GLOSSARY OF TERMS Asset – An asset is a physical component of a utility’s system, which deteriorates over time as the system ages. An asset for a water system can be visible or invisible (buried) and can include: pipelines, valves, tanks, pumps, wells, hydrants, treatment facilities, etc.1 Asset Attribute – the specific data attributed to an asset. These characteristics can be physical, financial, location, and asset management related. Asset Management – Asset management is an integrated set of processes to minimize life cycle costs of assets, at an acceptable level of risk, while continuously delivering established level of service. 2 Asset Management Plan – An Asset Management Plan (AMP) is a tool to help a utility implement its Asset Management Program. The AMP helps the utility ensure its ability to deliver the required level of service by determining when it’s appropriate to repair, replace, or rehabilitate assets and developing a long-term funding strategy to pay for these investments. MDEQ requires an AMP to have five core components: Asset Inventory, Level of Service, Criticality Assets, Revenue Structure, and Capital Improvement Project Plan. Capital Improvement Plan – A Capital Improvement Plan (CIP) is a multi-year program for expenditures for rehabilitation, replacement, and balancing of municipal infrastructure systems. Projects considered through the CIP process involve proposed investment in the City’s infrastructure and facilities, such as police and fire stations, parks and recreation facilities, community centers, offices, roads and sidewalks, and utilities. Consequence of Failure – Consequence of failure analysis should consider all the possible costs/impacts of an asset failure. Examples include: cost of repair, social cost, repair/replacement cost, legal costs, environmental costs, regulatory impacts, or impacts to the community. 3 Critical Assets – Two questions are important to determine criticality – how likely is it that the asset will fail; and what is the consequence of failure? The assets that have the greatest probability of failure and the greatest consequences associated with the failure will be the assets that are the most critical. Determining asset criticality will allow a utility to manage its risk and determine where to spend O&M dollars and plan capital expenditures. 4 Horizontal Assets – Horizontal assets refer to pipelines and their appurtenances, usually inventoried in a Geographic Information System (GIS) asset inventory. Level of Service – Level of Service (LOS) defines the way in which the utility stakeholders want the utility to perform over the long term. The LOS can include any technical, managerial, or financial components the utility wishes, as long as all regulatory requirements are met. 5

Likelihood of Failure – Likelihood of Failure describes an asset’s probability of failing, based on several factors such as age, condition, failure history/maintenance records, historical knowledge, and/or specific testing records. Redundancy – Redundancy refers to whether there are other installed assets that can provide the same service (either partially or fully) if failure occurs. Redundancy can significantly reduce risk. If the asset is determined to be very critical, then redundancy would be recommended. 6 Risk (also known as Criticality) – Risk is evaluated by considering an asset’s likelihood of failure, consequence of failure, and redundancy. Vertical Assets - Vertical assets refer to discrete assets found at facilities such as treatment facilities, pump stations, and storage facilities. Vertical assets are usually inventoried in a Computerized Maintenance Management System (CMMS).

EXECUTIVE SUMMARY The City of Flint’s water distribution system consists of approximately 582 miles of water pipelines and associated appurtenances, pumping facilities (Cedar Street, Torrey Road, West Side Avenue Pump Stations), the Flint Water Treatment Plant’s Pump Station #4 and Control Station #2, and water storage facilities (Cedar Street, Dort, and West Side Reservoirs, Clear Well #4, and WTP Elevated Storage Tank). This Asset Management Plan summarizes the following components for these assets: Asset Inventory, Level of Service, Critical Assets, Capital Improvement Project Plan, and Revenue Structure, in accordance with the guidelines and best practices outlined by MDEQ. For the purposes of this Asset Management Plan (AMP), the critical assets will be evaluated with a risk score.
ES-1 Asset Inventory This plan is focused on potable water distribution system assets which are owned, maintained, and operated by the City. The horizontal assets include: distribution mains, fire hydrants, control valves, system valves, meters, and service laterals. Meters and service laterals are not currently in the GIS inventory; however, it is recommended they are added in the future, and included in future AMP updates. The vertical assets in the AMP include: mechanical, structural, heating, ventilation, and air conditioning (HVAC), and electrical assets at the treatment facility, pump stations, and water storage facilities. The horizontal assets inventory was based on the Geographic Information System (GIS) and hydraulic model data in conjunction with field survey efforts and scanned atlas drawings. The vertical asset inventory data is currently housed in asset spreadsheets, which the City uses for maintenance management. Only basic attribute data was included in these spreadsheets - such as facility, asset ID, and asset name. As part of the AMP development, condition assessment of pump station assets was performed, and additional physical attributes were captured from the asset nameplates. Improvements in attribute data gaps are recommended for the horizontal asset inventory. Pipe installation years were assumed based on pipe replacement project dates and hydrant fabrication dates for the AMP risk analysis. The accuracy of pipe installation years affects the pipe’s estimated useful life (EUL), critical for rehabilitation and replacement (R&R) planning. The City plans to implement Cityworks Computerized Maintenance Management System (CMMS) in 2018. Horizontal and vertical asset inventories should be included in the CMMS program, utilizing the AMP developed hierarchy for vertical assets. An asset hierarchy is not required for horizontal assets unless the City would like to review asset risk by zones. Comprehensive SOPs are recommended to ensure the asset inventory is maintained as changes occur over time.
ES-2 Level of Service The City drafted twenty-five Level of Service (LOS) measures and key performance indicators (KPIs) using guidance from the MDEQ and the American Water Works Association’s (AWWA) Utility Benchmarking publications. The measures will be implemented in a tiered approach, with Tier 1 containing the most important measures to maintain the required LOS. The City will use a pilot program to implement the Tier 1 measures, so that adjustments can be made to the program before rolling out Tier

2 and 3 measures. The City will use the model of “Plan-Do-Check-Act” to ensure the performance management program is continually enhanced throughout its five-year full implementation. During the implementation phase of the City’s asset management (AM) program, the City will need to develop LOS definition sheets to identify owners and targets for the selected measures.
ES-3 Critical Assets To determine critical assets, a risk analysis was performed, including an asset-level evaluation of the likelihood of failure (LOF), the consequence of failure (COF), and asset redundancy. The likelihood of failure analysis is based on the physical and performance condition of assets, and the consequence of failure analysis is based on a Triple Bottom Line (TBL) approach evaluating economic, social, and environmental impacts. Risk scoring for horizontal and vertical assets is distributed on a scale from 1 (lowest risk) to 25 (highest risk), and assets are organized into one of five risk groupings: Lowest (1 – 5), Low (6 – 10), Medium (10 –16), High (16 – 20), and Highest (21 – 25). The majority of horizontal and vertical assets were categorized as having Lowest to Medium Risk. The highest risk horizontal assets included pipes with high LOF with the ability to impact multiple customers if failure occurs. The high LOF scores were due to the age of pipe and results from the hydraulic model (i.e. low c-factor or high head loss). Overall, the system included only 0.25% of highest risk scoring pipes; with the majority of pipes falling into the lowest risk category.
Table 1: Horizontal Critical Assets Summary
Risk Group Segments Miles % System
Lowest Risk (1-5) 8,392 277.00 47.5%
Low Risk (6-10) 5,764 174.00 29.8%
Medium Risk (11-15) 2,639 7900 13.6%
High Risk (16-20) 1,541 51.00 8.7%
Highest Risk (21-25) 28 1.50 0.3%
The vertical assets were mostly categorized as lowest risk, with only 5 assets (or 3%) falling into the high-risk category. This is due to limited data to evaluate the asset performance issues and redundancy in the system. Currently, not all of the facilities are being operated and there is ample redundancy at the pump stations. The high-risk vertical assets are pumps at multiple facilities and the Cedar Street Pump Station building. Many of the pumps have an increased LOF due to leakage issues, corrosion, and steel/concrete support issues. At the time of the inspection, the building at the Cedar Street Pump Station had a flooded basement. Additional investigation is needed to evaluate if there was any damage caused by the flooding to the substructure. The consequence of these failures are high replacement costs and time (up to 24 hours) required to respond and repair the assets.

ES-4 Capital Improvement Project Plan For linear assets, Arcadis used a GIS-based capital planning model that applies service level, criticality, condition, pipe deterioration curves and replacement cost criteria in conjunction with budget alternatives to plan for the replacement & rehabilitation. Various budget scenarios were modeled to show how the system-wide condition and risk change based on higher or lower funding levels. This allows for choosing the most appropriate long-term funding to achieve service level and risk goals. The model was configured to allot 20% of funding to high risk pipes and 80% of funding to those in the worst condition (high LOF score). For example, in 2018, $12 million was budgeted for water main replacement. Therefore $2.4 million went to replace the highest risk pipes and the remaining $9.6 million was used to replace the worst condition pipes. This configuration ensures that the highest risk pipes due to poor performance scores are replaced while still applying funds to minimizing the rising break rate. Four funding scenarios were run based on this configuration. All three scenarios start with the previously planned funding of $12M in 2018, $19M in 2019 and $7M in 2020. Scenario 1 is also based on the previous plan which allocated a constant $5M per year from 2021 through 2037. Scenario 2 increased funding by $0.5M each year starting at $7M in 2020 and finishing at $15.5M in 2037. Scenario 3 increased funding by $1M each year starting at $7M in 2020 and finishing at $20M in 2037. Scenario 4 increased funding by $2M each year starting at $7M in 2020 until reaching and holding $21M per year from 2027 through 2037. The following table shows how the break rate, physical condition, performance condition, overall LOF, and risk change by the end of each scenario. All scenarios show an increase in break rate and thus the physical condition, but the performance condition shows marked improvement in each scenario. This is primarily because almost 47% of the water mains have initial performance scores of 4 or 5, which represents poorer condition. In Scenario 1, the increased physical score overwhelms the improved performance score, resulting in an increased risk score. The better physical scores of Scenarios 2, 3 and 4 along with the reduced performance scores result in a risk reduction as shown in the table below.

Scenario 3: $1.0M Ramp Up
2037 39.33 2.53 1.93 2.84 6.05 42.2%
Scenario 4: $2.0M Ramp Up to $21M/year
2037 34.90 2.35 1.73 2.63 5.59 37.1%
Scenario 3 represents the recommended funding scenario. It includes an aggressive ramp up of water main replacement as shown in the following figure. Over 20 years, $310M is spent to replace 198 miles of water mains, which is 1/3 of the existing system. Although the system wide break rate increases initially, it levels off and reduces to under 40 breaks per 100 miles per year. Maintaining a target of 40 breaks per 100 miles per year represents maintaining the current condition of the system. Scenario 3 Risk is gradually reduced almost every year in the plan.

For Vertical Assets, Arcadis developed capital projects in Excel based on the risk analysis and remaining useful life. The risk evaluations for vertical assets yielded twenty-four assets that are recommended to be replaced within the next five years based on risk, present condition, and remaining useful life. The following chart indicates the number of assets to be replaced in the following increments, based on the risk and RUL analysis: 0-2, 3-5, 6-10, 11-20, and 20+ years. All critical assets are included for replacement in the first five years.

Figure 2: Assets Replacement based on RUL
Installation cost was estimated based on the methodology outlined in Section 6.3.2, for the twenty-four assets recommended to be replaced or repaired in years 1-5. For mechanical, electrical, and HVAC assets, complete replacement of the asset was considered at the end of the asset’s useful life and replacement cost was estimated for the asset. For structural assets, since complete replacement is unlikely due to the expense, structural repairs were estimated and used in the analysis. CIP Group 1 includes R&R of assets with an RUL from 0 up to 2; CIP Group 2 includes R&R of assets with an RUL 2 up to 3; CIP Group 3 covers assets with RUL 3 up to 4; CIP Group 4 covers RUL 4 up to 5 and CIP Group 5 covers RUL 5 up to 6. A total investment of almost $2M is required to rehabilitation/replace these assets over the next five years, as illustrated in the chart below. Based on discussions with the City, there is a line item included in the current CIP line item for “Pump Station Improvements” that could potentially cover the anticipated replacement needs. If it is determined that the anticipated replacement needs ($2M) for the first five years are not addressed in the current CIP, then the financial model will need to be adjusted accordingly.

* It is assumed that the approximately $2M in anticipated vertical asset R&R is addressed in the current “Pump Station Improvements” CIP line item, so no additional investment is shown here for vertical assets. If this is not the case, the financial model will need to be adjusted accordingly to include the anticipated investment for vertical assets.
The investment in horizontal assets, based on the recommended capital model scenario outlined in Section 6.4, will require $1M additional funding each year to replace poor condition, high risk pipes. Therefore the 20-year CIP will include $1M increases each year as listed in the table below, ending at $24M in 2037. The total investment in horizontal assets R&R is $310M, with a total of approximately 200 miles replaced.
2017 WATER SYSTEM ASSET MANAGEMENT PLAN

For vertical assets, the 5-year CIP is assumed to be addressed in the Pump Station Improvements CIP line item, so no additional investment is shown for the 5-year period. Beyond the 5-year CIP, an average R&R rate of 3% was estimated based on the overall replacement cost of the pump stations.

As noted above, Scenario 3 is the recommended Asset Management Plan for the City. The financial analysis in Section 6.0 of this Report outlines the analysis that determines the estimated funding gaps, as well as the revenue increases needed to meet the following:
Annual O&M expenses, including water system operation and maintenance and annual payments for water service.
Cash Funded Capital – This includes annual amounts to fund the cash portion of the City’s CIP, and annual replacement amounts for Scenario 3 for horizontal and vertical assets.
Reserve Balances – This includes transfers to or from the available Operating Fund balance. The City targets for the Water Fund to maintain 25 percent of the annual expenditures for O&M and debt service, and Transfers to the General Fund.
The following chart reflects the funding gap for implementing the Scenario 3 Asset Management Plan
2017 WATER SYSTEM ASSET MANAGEMENT PLAN
arcadis.com 9
Figure 4: Funding Gap Summary
To close the funding gap, the City will need regular increases to its water system rates and charges. This includes the annual increases noted in Table 66 of Section 6.4. The percent increases needed assume that the City will fund the annual Scenario 3 requirements from water system operating revenues. The City has indicated that it will be extremely difficult to undertake the revenue increases necessary to implement the Scenario 3 plan. As such, it will pursue various other funding sources such as state and federal grants to offset the funding gap. It also plans to offset rate impacts through initiatives that would improve operating efficiencies; improve revenue collection rates; or enhance low-income assistance. These alternative funding sources and initiatives would help close the funding gap for the Scenario 3 plan beyond FY 2022. The City could also attempt to pursue future state revolving fund loans or other financing for a portion of the Scenario 3 replacements. In recent years the City retired its outstanding debt service, and this Asset Management Plan does not reflect a plan for the City to issue debt or take advantage of state revolving fund (SRF) loans. If available, and if desired by the City, these mechanisms could push revenue increases to future fiscal years, and mitigate revenue increases as the Scenario 3 replacement capital ramp up begins.
ES-5 Revenue Structure The City currently utilizes a two-part rate structure for its water system. The first part includes a monthly service charge that is graduated by meter size (5/8-inch to 20-inch). The volume charge is a declining block structure with three blocks:

Using the current rates, projected accounts, and volumes by block provided by the City, Arcadis estimates the City’s water system will produce the following annual revenue for the 5-year period FY 2018 to FY 2022. As is seen, the revenue under existing rates increases slightly due to projected better collection rates from billings to customers over the next five years. The City projects that it will collect approximately 65% of billings from Residential customers in FY 2018, but expects this to improve to 85% by FY 2022.

Water system revenues are managed in the Operating Fund and are used to meet the revenue requirements of the system. The City targets an Operating Fund balance of 25 percent of annual operations and maintenance (O&M) and debt service expenditures. The projected 5-year revenue requirements consist of O&M expense and cash funded capital (including replacement of horizontal and vertical assets). The following presents the projected water system revenue requirements:

As is seen, water revenues under existing rates are less than the projected revenue requirements. To close the gap and maintain the appropriate balance of cash reserves in the Operating Fund, Arcadis estimates that the following annual revenue increases would be needed:

Arcadis also evaluated the 20-year revenue requirements for O&M and cash funded capital. The 20-year projection in Section 6.4 includes Arcadis’ estimate of needed horizontal and vertical asset replacement for Scenario 3 of the Section 5.4 Asset Management Plan. The analysis included maintaining the Operating Fund at a balance of 25 percent of O&M and debt service. Beyond FY 2022, the analysis reflects that annual revenue increases of 3 percent to 7 percent would be necessary should these be funded with cash from operations. The financial analysis reflects a conservative estimate of the revenue increases that would be necessary to meet the revenue requirements associated with Scenario 3 of the Asset Management Plan. There are several areas and initiatives that could mitigate the revenue increases, including:
Pursuit and attainment of additional state and federal grants to fund a portion of the projected capital improvements
Use of state revolving fund loans or other debt financing options as feasible to fund a portion of future capital improvements
Water shut off policy to improve revenue collection rates from customers
Improving operational efficiencies
Enhancing low-income assistance programs for customers
Alternative water rate structure to mitigate impact on low-income customers
As the City evaluates or undertakes areas and initiatives, Arcadis recommends that the City perform regular financial planning to derive the optimal financial plan that mitigates rate impacts to customers.

1.0 ASSET MANAGEMENT PROGRAM OVERVIEW
1.1 City and Water Department Overview The City of Flint operates a public water system which supplies drinking water to a population of over 98,000 through 582 miles of distribution mains. The system supplies an average of 13.2 million gallons per day (MGD). Incorporated in 1855, it is estimated that the City of Flint’s first water distribution pipelines were installed as early as 1912. The City currently purchases finished water from Great Lakes Water Authority (GLWA), boosting the concentration of chlorine and orthophosphate for corrosion control and adjusting the PH, prior to distribution. The City also owns and operates the Flint Water Treatment Plant (WTP), which was originally constructed in 1952, and recently renovated in 2014. The plant has historically been used as a backup supply with the ability to intake from the Flint River. However, an interconnection with Genesee County will serve as a future backup supply. Four pump stations, Pump Station #4, Cedar Street, Torrey Road, West Side Avenue Pump Stations were constructed in 1948, 1948, 1948, and 1972, respectively. The City maintains five storage facilities, as listed below. Under current operating conditions, the Dort Reservoir, Clear Well #4, West Side Avenue Pump Station and Reservoir are not in use.

Overall, the City of Flint’s water distribution system includes approximately 582 miles of pipelines and appurtenances, and vertical assets at four pump stations, one water treatment plant, control station 2, and five storage facilities. Historically, the City purchased water from GLWA; however, in 2013, the City decided to purchase water from a new regional water supplier, the Karegnondi Water Authority (KWA). During the transition, the City drew water from the Flint River and treated the water via the Flint WTP prior to distribution. Following the City’s drinking water crisis, the City switched back to the finished water supply from GLWA. A 30-year contract to continue purchasing water from GLWA was signed in November 2017. That contract includes a credit from GLWA to the City for the share of the KWA raw water pipeline debt. In addition, an interconnection with Genesee County is being constructed to serve as a backup supply. The City is currently undergoing a Water Distribution System Optimization effort, which involves several components including identification and implementation of distribution system operational best practices, standard operating procedures, corrosion control testing, hydraulic modeling and system operations

recommendations, Enterprise Asset Management (EAM) functional requirements definition, and the development of this AMP. The recommendations from the Hydraulic Modeling Technical Memorandum (issued as draft in October 2017, and currently being updated) was used to develop an understanding of what facilities will be included in the future water distribution system. This AMP assumes that the future plan for water distribution facilities in operation will include:
Treatment: Flint Water Treatment Plant, consisting of flow monitoring and chemical adjustment only (chlorine, orthophosphate and pH – depending on water quality)
Pumping: Cedar Street Pump Station, Pump Station #4, Torrey Road Pump Station o West Side Avenue Pump Station will remain out of service
Storage: Cedar Street Reservoir, WTP Elevated Tank, and Dort Reservoir (placed into service) o West Side Avenue Reservoir and Clear Well #4 will remain out of service
1.2 Brief History of Asset Management Efforts
The City has performed many studies and master plans over the years. In 2008, the City of Flint Water System Review (Michigan Department of Environmental Quality (MDEQ) 2008) cited many key improvements necessary to the water supply, including the recommendation to develop an Asset Management System. The City embarked on subsequent asset management activities including field verification of hydrants and valves, the development of a GIS-based model, the development of a replacement program for assets more than fifty years old, and various assessments of pumping and treatment facilities. However, like many water utilities across the country, the City lacked the resources to implement the proposed Asset Replacement Program and other recommendations documented within the reports. City resources often were shifted away from this preventive work to respond to corrective issues, such as emergency breaks or construction activities.
In 2014, the City experienced a highly-publicized drinking water crisis. In response to the state of emergency declaration and United States Environmental Protection Agency (USEPA) emergency administrative order, multiple projects were initiated between 2015 and 2017. Efforts related to asset management included:
Resume purchasing water from the Great Lakes Water Authority (formerly Detroit Water and Sewerage Department)
Provide an inventory of lead service lines, water interruptions, and unoccupied homes
Develop and implement a distribution system water quality optimization plan (Arcadis 2017)
Valve Assessment and Exercising (Wachs Water Services 2015)
Development of a Capital Improvement Plan (DLZ Michigan 2015)
Deliver a Fiscal Year 2016 Year-End Report (Water Service Center 2016)
In 2016, the City published their first Draft Asset Management Report (Rowe Engineering 2016). The purpose of the report was to “…develop an inventory and define the needs of the City’s utilities and roadways.” It was a good first step in the process of asset management and began to provide information for the City to make decisions and establish priorities for maintenance and replacement of the City’s infrastructure. The Report was reviewed by the MDEQ and feedback was provided for areas of improvement, to be addressed in future updates, which are now included in this document.
2017 WATER SYSTEM ASSET MANAGEMENT PLAN
arcadis.com 14
1.3 Purpose of This Document The purpose of the 2017 Water System AMP document is to build upon the first Asset Management (AM) report and further develop and implement an AMP with the following criteria:
Meets the minimum criteria established within the MDEQ Asset Management Program Checklist and Asset Management Guidance for Water Systems (Appendices A and B, respectively)
Includes the following core components: Asset Inventory, Level of Service, Critical Assets, Capital Improvement Project Plan, and Revenue Structure
Addresses all assets related to potable water distribution, pumping, and storage assets maintained by the City’s Department of Public Works - Water Service Center and Water Treatment Plant divisions
Contains a schedule for the development and implementation of an AM Program that can be achieved in 3-5 years
Is submitted to the MDEQ on or before January 1, 2018
1.4 Mission, Goals, and Asset Management Strategy The Mission Statement for the City of Flint’s Asset Management Program is as follows: We commit to protecting public health through the effective management of our drinking water system pumping, storage, and distribution assets. We strive to make the most cost-effective renewal and replacement investments in our system, while being transparent in justifying our investment decisions to our stakeholders. We endeavor to win back the confidence of our customer base through implementing best practices and industry standard asset management practices to ensure our system yields safe drinking water. The goals of our Asset Management Program are the following:
Increase customer confidence in our ability to effectively manage our assets.
Work together, across divisions, to ensure utility-wide buy-in to asset management practices.
Produce a risk-based CIP that will justify a 20-year asset rehabilitation and replacement plan
Work together, with our customers, to reduce delinquent accounts and increase collection rates over the next five years.
The objectives of our Asset Management Program are the following:
Develop an Asset Management Plan, acceptable to the MDEQ, by January 1, 2018. The AMP will be updated at least annually going forward.
Implement a full Asset Management Program based on industry best practices and MDEQ guidance in the next 3-5 years.
Develop a transparent capital improvement plan that can be easily justified to our stakeholders by 2019.
Implement an Enterprise Asset Management (EAM) program to bring success to our program through effective management of asset inventory, condition, COF, and risk data by 2020.
2017 WATER SYSTEM ASSET MANAGEMENT PLAN

Implement a proactive asset replacement strategy to ensure reliable water supply to our customer base in time for the 2021 CIP.
1.5 Adopted Framework In the United States, the USEPA promotes the use of AM and application of associated strategic AM concepts such as level of service, life cycle analysis, and risk. This focus builds on the development of asset management elsewhere, with the International Infrastructure Management Manual (IIMM) spearheaded in Australia and New Zealand, and the British Standards Institution’s Publicly Available Specification 55 (PAS 55) for asset management in the United Kingdom. Over the last decade, these concepts have been widely adopted and continually refined in these countries. Recently, in the United States, municipalities and utilities have begun to recognize the need to develop a more structured approach to ensure accurate/defendable budget forecasting and project prioritization. A wide variety of organizations have published their own unique approach to asset management, as there is no “one size fits all” standard. The City’s approach to the development of the AMP is based firstly on MDEQ Guidance, and complies with both of the following publications:
Asset Management Program Review Checklist (MDEQ 2017) – Appendix A
Asset Management Guidance for Water Systems (MDEQ 2013) – Appendix B The MDEQ Guidance requires five core components to an AMP: Asset Inventory, Level of Service, Critical Assets, Revenue Structure, and Capital Improvement Project Plan. The AM Program Review Checklist provides specific details as to what information should be included in each section. In addition to meeting these minimum requirements, the AMP considers other best practices, such as:
Asset Management Guidance and Best Practices (USEPA 2008)
Asset Management Systems Requirements and Guidelines for the Application of ISO 55000-2 (International Organization for Standardization 2014)
International Infrastructure Management Manual (IIMM 2015)
IAM Anatomy of Asset Management (Institute of Asset Management 2015) Lastly, the City of Flint considered the goals and objectives in the AMP development. The goals and objectives were developed through conversations with AM Steering Team Representatives: Rob Bincsik, Director of Public Works and Mark Adas, City Engineer. The result is a blended approach to AMP development illustrated in the following diagram.

2.0 ASSET INVENTORY
2.1 Assets Included in AMP The AMP is focused on potable water distribution system assets which are owned, maintained, and operated by the City. The horizontal assets included in the AMP include: distribution mains, fire hydrants, control valves, and system valves. Meters and service laterals are not currently in the GIS inventory; however, it is recommended they be added in the future, and included in future AMP updates. This may be accomplished as part of a comprehensive AMI project that the City is planning. The vertical assets included in the AMP are: mechanical, structural, HVAC, and electrical assets at the treatment facility pump station and control station, other pump stations, and water storage facilities. Fixed assets excluded from the AMP are: water treatment plant (except pump station 4 and control station 2), dams, other minor water-related appurtenances/facilities, water administration buildings, facilities, and yards, land/real estate, and other asset types (wastewater, stormwater, streets, traffic, etc.). Non-Fixed Assets (also known as expendable/portable assets) which are not included are: fleet, equipment/major tools, spare parts inventory, office equipment and computers, etc. Since the scope of this AMP is to address horizontal and vertical water distribution assets, these other assets will not be included in the AMP. It is the intention that the AMP will serve as a template and other City asset types could be added as separate documents.
2.2 Asset Definition and Level of Detail
2.2.1 Horizontal Assets
The horizontal asset water main inventory was based on the GIS and hydraulic model data in conjunction with field survey efforts and scanned atlas drawings. The GIS has been updated based on the ESRI Local Government Information Model (LGIM) format. The GIS is built within an ESRI personal geodatabase named Flint_pgdb.mdb, using the NAD 1983 State Plane Michigan South International Feet projection. This geodatabase was initially populated from different data sources provide by the City. Water mains were populated from a shapefile named WaterPipes_83. These pipes were matched to the hydraulic model and adjustments were made to both datasets to align pipe segments, geometry, and diameters. Through this process, 17,683 segments representing 573.54 miles (98.58%) of the GIS water mains were linked to the hydraulic model data. The link was established by storing the unique hydraulic model label attribute in the GIS Model_ID attribute. Fire hydrants and system valve assets were populated from a file geodatabase named Flint_Master_GDB. This geodatabase utilized the NAD 1983 State Plane Michigan South US Feet projection, therefore the feature classes were re-projected to International Feet. Additional fire hydrants and water valves assets were field surveyed and appended to their respective feature classes. Currently, these surveyed appurtenances do not line up with the water main features. This is not a major short-term
2017 WATER SYSTEM ASSET MANAGEMENT PLAN
arcadis.com 20
problem, because these appurtenances are not considered a primary asset. Future data clean-up should be performed to align the water mains with these surveyed points. The water main feature class within GIS and the hydraulic model did not contain any asset installation dates. The City identified mains that were part of eight recent water main replacement projects between 1998 and 2012. These pipes were assigned install years based on their respective project years. The hydrant data included the fabrication year for 3,503 of the 3,604 records (97.2%). This data was used to estimate the water main installation years which were not populated. To be conservative, the oldest hydrant fabrication date was assigned to the nearest stretch of water main having the same diameter and material from interaction to intersection. Hydrant fabrication dates after 1995 were ignored because the eight replacement projects captured all the new water mains. The remaining pipe install years were populated based on adjacent connected pipes where the hydrant fabrication year was applied. If better information becomes available in the future, these install dates should be updated in a future AMP update. GIS network structures were populated based on the hydraulic model tanks and reservoirs. Pumps in the GIS were also populate based on the hydraulic model. Populated LGIM feature classes are as follows.
Table 12: Assets Feature Classes
Feature Class Description Quantity Length (miles) Category

wNetworkStructure Storage Nodes 9 NA Vertical Asset
wPump Nodes 14 NA Vertical Asset
wSystemValve Nodes 9,577 NA Appurtenance
Only the water mains are considered assets for the capital planning model. Although there are 18,655 water main segments (589.12 miles) in the GIS, only 18,364 segments (581.84 miles) are owned by Flint, active, connected and are not piping within a pump station facility boundary. Information regarding horizontal assets in the rest of this document will be related to the 582 miles water mains. Network structures and pumps are contained within the GIS but are considered under the vertical asset category. Appurtenances such as valves and hydrants are not considered individually, however they are accounted for within the water main replacement costs based upon typical spacings.
2.2.2 Vertical Assets
The City of Flint determined that the following three questions will guide the definition of a vertical asset for the AMP.
1. Will a work order be written to this specific item? 2. Will a separate condition assessment need to be performed on this item?
2017 WATER SYSTEM ASSET MANAGEMENT PLAN
arcadis.com 21
3. Will depreciation or costs need to be tracked separately on this item?
The specific level of detail was defined further for mechanical, electrical, HVAC, and structural assets so that it is clear to what granularity assets will be tracked. Mechanical assets are defined as:
All pumps and process mechanical equipment
All actuated gates/valves
Manual valves >= 14” are assets (cost dependent). o Valves < 14” are assessed as part of the piping collection. o Actuators are assessed as part of gate/valve
Cranes, hoists, sump pumps
Electrical assets are defined as:
All motor control centers (MCCs) o Individual MCC buckets are assessed as part of the overall MCC.
Electrical panels
Transformers
Generators
Variable frequency drives (VFDs)
Motors (over 100 HP) o Motors less than 100 HP are assessed as part of the piece of equipment.
Remote instrumentation and remote-control panels are assets. o Local instrumentation or control panels are assessed as part of the piece of equipment. o PLC/RTU assessed as part of control panel, except stand-alone PLC panels in the
control room which are considered assets.
I&C assets such as: transmitters, controllers, analyzers, SCADA equipment, etc. HVAC assets are defined as:
Fans (exhaust and supply)
Unit heaters
Dehumidifiers
Air conditioners Structural assets are defined as:
Buildings o The building roof is defined as a separate asset
Process tanks (buried or above ground)
Process structures (wet wells, chambers, etc.)

2.3 Asset Attributes Asset attributes describe an asset’s characteristics and they generally fall into four categories: physical, financial, location, and asset management related. The tables in each section below lists each type of attribute and where the data should be stored and maintained.
2.3.1 Horizontal Assets
The GIS houses attributes such as material, diameter, length, and install year. Additionally, financial and asset management attributes have been loaded into the GIS from the data source listed below.

2.3.2 Vertical Assets
The vertical asset data is currently housed in asset spreadsheets, which the City uses for maintenance management. Only basic attribute data is included in these spreadsheets - such as facility, asset ID, and asset name. As part of the AMP development, condition assessment of pump station assets was performed, and additional physical attributes were captured from the asset nameplates. As the City prepares for Cityworks implementation in 2018, this asset data should be used as a basis for populating the CMMS.

2.4.2 Vertical Asset Inventory
Asset inventory for vertical assets for the City of Flint is currently maintained in an asset register spreadsheet and summarized in Appendix C. As part of the AMP development effort, asset inventory and condition assessment activities were carried out at four facilities, listed below, and detailed asset inventory, attribute, and condition data was recorded. A total of 160 assets were assessed, and likelihood of failure, consequence of failure, and risk evaluations were performed on these assets, which is detailed in Section 4.

at this time. The City of Flint has identified the location of the water storage facilities on its system-wide map, and they are contained within the GIS and the hydraulic model being developed. A future step can be to perform structural condition assessments and COF analyses of the storage facilities once the City confirms which facilities will be used going forward. In addition, a structural assessment was performed on the Dort Reservoir in 2017. This plan will be updated with this information if the City chooses to utilize the Dort Reservoir for future operations.

2.5 Data Improvements
2.5.1 Incomplete or Low Confidence Data
As part of the AMP development effort, data gaps were identified in the GIS and those gaps were closed to perform a complete risk assessment. The updates to the GIS are detailed in Section 2.2.1; recommendations for further improvements to both horizontal and vertical asset data are outlined below.
2.5.2 Recommendations for Improvements
2.5.2.1 GIS Improvements
The horizontal asset inventory is contained within the GIS and has been updated as part of the AMP development effort. Some additional recommendations for improvement include:
1. The assumed installation years, based on hydrant fabrication represents the least confident data that has the greatest impact on replacement planning and defining critical assets. All available record drawings and institutional knowledge should be mined to update the install years with more confident data.
2. The 26 water mains with unknown diameters should be researched and updated. 3. The 85 water mains with unknown material should be researched and updated. 4. The locations of water mains should be updated based on the field surveyed hydrant and valve
locations. Additional field location work may be needed in area with minimal survey data. 5. A review of asset definition and hierarchy should be performed prior to the implementation of
Cityworks. If the segments are too small, it will be problematic to write work orders to specific pipe segments.
6. Consider adding meters and service lines as part of future AMI project.

2.5.2.2 CMMS Implementation
The City currently manages its vertical asset inventory with spreadsheets and hard-copy work orders for maintenance activities. The City expects to be implementing the Cityworks CMMS program in 2018. The vertical asset inventory developed as part of the AMP development should be prepared for import to the new Cityworks program. Vertical asset data is best organized in an asset hierarchy and includes unique asset identification numbers and associated asset attributes. Vertical assets that were condition assessed were organized into a five-level asset hierarchy as follows:
1. Utility (City of Flint) 2. Facility (Flint WTP, West Side Pump Station, Cedar Street Pump Station, Torrey Road Pump
Station) 3. Process (Chemical Feed, HS Pumping, Booster Pumping) 4. Group (Valves, Cranes, Pumps, Electrical, HVAC, Buildings, I&C, Sump Pumps) 5. Asset
It is recommended that this hierarchy framework be used going forward, as the City prepares its data for Cityworks implementation. It is important that the City’s asset inventory is maintained properly so that it remains an accurate representation of the asset base. It is recommended that standard operating procedures (SOPs) for adding and removing assets, and updating asset data in the CMMS are developed to ensure the asset inventory is maintained properly. Recommendations include:
1. Utilize the detailed asset and condition data for the four visually assessed facilities. 2. Develop a detailed asset inventory for the water storage facilities. 3. Perform a field condition assessment and COF analysis for water storage facilities. 4. Build the hierarchy for Cityworks based on the hierarchical framework developed for condition
assessment. 5. Develop SOPs for addition, modification, and removal of assets from CMMS. 6. The installation years used were based primarily on facility construction dates and secondarily on
institutional knowledge on process (e.g. chemical feed) or group (e.g. pumps, HVAC) replacement dates. The City would have a more accurate representation of install dates if a review was conducted of all available records, nameplates, and institutional knowledge on an asset by asset basis.

3.0 LEVEL OF SERVICE
3.1 Development Methodology Four main sources provide guidance for the development process for Levels of Service (LOS): Effective Utility Management Primer, AWWA Benchmarking publications, MDEQ Guidance, and the City’s goals and objectives for its Asset Management Program. For the development of Levels of Service, the MDEQ Guidance has included fifteen questions to consider:
1. What is the LOS goal for health, safety, and security? 2. How often is the system out of compliance with regulations? 3. Are the operators properly certified? 4. How does the utility stay aware of and prepare for new regulations? 5. Do you share your LOS statement with your customers? 6. How do you track and respond to customer needs/complaints? 7. Can the current process be improved? 8. How quickly does the utility respond to customer issues? 9. Is maintenance being deferred to save money? 10. How much will the improvements cost and how will they be funded? 11. Are assets being properly maintained to insure they are in reliable working condition? 12. What areas within the system are most important to insure the best LOS possible? 13. When considering a preferred LOS, are asset age and life cycles, asset conditions, funding
availability, etc. being factored in? 14. How often will the LOS statement be reviewed in order to capture changes such as funding
availability (growth and decline), regulatory requirements, demand of customers (increases/decreases in customers), and physical deterioration of assets (addressing water loss/maintenance)?
15. Are O&M activities being maximized to meet the LOS goals?
The City of Flint’s Levels of Service will also consider the best practices outlined in the ISO 55000 Standard. ISO 55000 refers to Levels of Service as “Objectives” and outlines the following requirements:
1. Provide the essential link between the organizational objectives (i.e. your strategic plan) and the asset management plan(s)
2. Are tailored to suit each organization’s needs, which may include addressing subsets of objectives (e.g. for the asset management system, asset portfolios, the asset system and at asset level)
3. Can vary for different functions carried out to meet stakeholder requirements 4. Should consider information or data from internal and external sources including contractors, key
suppliers, regulators or other stakeholders 5. Should be “SMART” -specific, measurable, achievable, realistic and time-bound 6. Can be both quantitative measurements (e.g. mean time between failure) and qualitative
measurements (e.g. customer satisfaction)
2017 WATER SYSTEM ASSET MANAGEMENT PLAN

There are hundreds of performance measures used in the water and wastewater sector. The Effective Utility Management (EUM) Primer and the MDEQ guidance were both used as resources in the development of the City of Flint’s LOS and performance measures. The EUM Primer was originally released in 2008 and has been updated recently in January 2017.The Primer outlines ten categories for an effectively managed utility, listed below:
Product Quality
Customer Satisfaction
Employee and Leadership Development
Operational Optimization
Financial Viability
Infrastructure Strategy and Performance
Enterprise Resiliency
Community Sustainability
Water Resource Sustainability
Stakeholder Understanding and Support The City of Flint developed an LOS statement to guide the development of the measures: The City strives to provide safe drinking water to its customers, meeting all regulatory requirements, through the effective maintenance of its assets. The City will review the LOS statement annually as part of the AMP review and update effort. The following goals and performance measures will be implemented to ensure this LOS statement is met.
3.2 LOS Goals and Performance Measures The City will implement a tiered approach to performance measurement, with the most important LOS and KPI goals implemented first in Tier 1. The City will need to develop LOS and KPI definition sheets in 2018 for the Tier 1 measures. The definition sheets will assign owners and targets for the measures. The implementation of Tier 2 and 3 measures will follow, after the Tier 1 measures are piloted and any necessary adjustments are made as part of the familiar continuous improvement cycle of Plan-Do-Check-Act. The approach enables staff buy-in and ensures that measures are meaningful for decision making. The City is currently in the process of selecting and implementing a CMMS and real-time modeling software. Once the systems have been implemented, the City will evaluate the data sources to determine if some additional leading indicators can be added to the selected LOS and KPIs shown below:

3.3 Performance Management Tracking Each of the twenty-five LOS and KPI goals will be further defined by the City of Flint as the pilot performance measurement begins with the Tier 1 measures. Many of the measures will be measured manually at the start, but as the City implements Cityworks, reports can be developed to make the process more automated. The table below includes recommended frequency and data source for each performance measure. Currently, targets for these measures are not defined. As the City pilots the Tier 1 measures, performance targets can be established, and adjustments may be made to the frequency and data source recommendations.

4.0 CRITICAL ASSETS
4.1 Likelihood of Failure (LOF) Factors and Scoring Scales
4.1.1 Horizontal Assets Factors and Scoring
For horizontal assets, physical condition is based on Estimated Useful Life (EUL) of different pipe materials and break data. The AWWA Buried No Longer EUL data and experience with other utilities by region were used to produce an exponential deterioration curve representing the break rate increase as a pipe ages.
The Buried No Longer EUL, measured in years, for Midwest water utilities, regardless of size is shown in the following table.
Table 22: AWWA Buried No Longer Estimated Useful Life by Material
Cast Iron Ductile Iron PVC Steel Concrete PCCP
Long Short Long Short 120 85 110 50 55 80 105 105
Cast iron and ductile iron have a range of EUL (from long to short) while PVC, steel, concrete and PCCP only have a single estimated serviceable age. Experience shows that smaller diameter cast iron and ductile iron have a shorter useful life than larger diameter mains. Cast iron pipe also was produced using different casting methods and to different standards over time. Cast iron was initially pit cast until about 1920 when spun cast became the standard. Spun cast had superior strength than pit cast therefore around 1945 the wall thickness was reduced to save cost. In general, pre-1920 cast iron is not as good as later pipe, but those that are still in service clearly were installed well and have not been subjected to typical stresses that would cause them to fail at an earlier age. For this reason, all pipe prior to 1945 were given the same relatively long EUL. Post 1945 cast iron were assumed to have a shorter EUL. Buried No Longer does not list galvanized pipe but experience shows this is typically used in smaller diameters and has a very short life compared to other materials.
The following table lists the EUL used for the pipe materials, sizes and install years in the City’s inventory. The pipes are listed as cohorts, which represent groups of pipes with different structural properties.

Each pipe of the City’s inventory is associated with one specific cohort. As a pipe ages, it follows its cohort degradation curve, thus increasing its break rate. Each pipe is assigned a physical
condition score from 1 to 5 based on its age and corresponding break rate. The condition score starts at 1 and increases by 1 for every increase of 20 breaks per 100 miles per year as shown on the right vertical axis. Pipes that have experienced a break have their break rate increased by 10 breaks per 100 miles per year.
For horizontal assets, performance condition is based on the hydraulic model C-factor and head loss gradient. Lower C-factors yield higher head loss and will result in reduced flows and pressure.
The performance and physical condition criteria are shown in Table 24. The final overall pipe condition score is the maximum of any of the three criteria.
Table 24: Physical and Performance Condition for Horizontal Assets
Criteria 1 2 3 4 5
Model Pipe C-Factor <= 100 > 50 and <= 100 > 30 and <= 50 > 15 and <= 30 <= 15
Model Head Loss Gradient (Ft/1000Ft)

Break Rate (per 100 miles per year)
<= 20 > 20 and <= 40 > 40 and <= 60 > 60 and <= 80 > 80
Actual Breaks Increase Individual Pipe Score by 10 breaks per 100 miles per year if a Break Occurred
4.1.2 Vertical Asset Factors and Scoring
There are two components of the vertical asset likelihood of failure assessment as well – physical condition and performance condition. Physical condition refers to the current state of repair and operation of an asset, as influenced by age, historical maintenance, and operating conditions. Performance condition refers both to the current state of performance and the ability of the asset to meet operational requirements in the future. To evaluate asset condition, a standard 1 to 5 scale is used (1 – excellent and 5 – very poor), which results in a comparative ranking of assets. The overall condition of an asset is the maximum of all the physical and performance condition criteria. The table below provides generalized descriptions which correspond to each physical condition score. For vertical assets, physical condition is evaluated through visual inspection and utilizing physical condition scoring criteria defined for each assessment type. Each assessment type includes the following criteria:
Mechanical – corrosion, leakage, vibration, and damage to concrete pedestals, steel supports, piping/valves, local panels, field instruments, and electrical connections.
Electrical/I&C – corrosion, vibration, dielectric leakage, electrical damage, damage to concrete
2017 WATER SYSTEM ASSET MANAGEMENT PLAN

pedestals, steel supports.
Structural – leakage, cracking, steel damage, wood damage, water drainage, roof damage, walkways/platforms, doors/hatches/windows.
HVAC – corrosion, leakage, vibration, concrete support/base damage, steel supports, piping/valves, local control panels, field instruments, electrical connections.
Core and ancillary criteria are defined in the tables below for each assessment type. Only the scores of core criteria carry forward to the risk calculation. Ancillary scores will not affect the overall score of the asset. However, if the ancillary criteria are in poor condition the City should replace or repair the ancillary item to prevent an asset failure as part of their maintenance work. The specific factors included in the evaluation of physical condition for mechanical, electrical, structural, and HVAC assets are listed in the four tables below:

The performance condition captures the modes of asset failure in addition to mortality, and include the following main factors:
Capacity – considers current and future needs Efficiency
o Reliability - average time equipment is available when needed o O&M Issues – frequency of O&M Issues beyond regular maintenance o Obsolescence – technology / availability of parts
Level of Service – considers current and future needs o Regulatory/customer commitments
The table below provides generalized descriptions which correspond to each performance condition score.
Table 29: Vertical Asset Performance Condition - General
Score Description of Performance Condition
1 – Excellent Meets all capacity and regulatory requirements in all current and future anticipated demand conditions. State of the art technology with overall excellent performance.
2 – Good
Meets all capacity and regulatory requirements in current and future anticipated average conditions. May have minor risk under current peak conditions and will not meet anticipated future peak capacity conditions. Future regulatory compliance may require some modifications. Overall performance excellent to very good with tried and true technology
3 – Moderate
Current capacity is acceptable under average conditions but does not consistently meet current peak condition and would likely not meet future peak conditions. Current regulatory requirements are met, but future requirements will likely not be met, even with modifications. Overall performance and efficiency are average.
4 – Poor Current performance is marginal and will not meet future additional requirements or increased demand (e.g. capacity, level of service goals and/or future regulatory requirements).
5 – Very Poor Current performance unacceptable and does not meet currently required performance criteria (e.g. capacity, level of service goals and/or regulatory requirements).
Performance scoring is completed through a desktop analysis that includes document reviews and staff interviews. For vertical assets, the factors considered in assessing the performance condition are shown below:

4.1.3 Horizontal Assets Likelihood of Failure Summary
For horizontal assets, a standard performance indicator for asset condition is the number of main breaks per 100 miles of distribution system. The breaks per year are listed in Table 31 along with the associated break rate based on 582 miles of water mains. This results in an average current break rate of 34.3 breaks per 100 miles per year. If one excludes the breaks related to the water crisis in 2014 and 2015, the average current break rate would be 29.6 breaks per 100 miles.

4.1.4 Vertical Assets Likelihood of Failure Summary
Likelihood of failure is based on the asset condition score, ranging from 1 (very good) to 5 (very poor). The assets with a physical and/or performance condition score of 4 or 5 are more likely to fail. Based on the physical condition assessment, 13% of assets are likely to fail, and based on the performance assessment, 3% of assets are likely to fail. Overall the pumps at the stations appear to be working, but near the end of their useful life as well as some of the chemical feed equipment. In additional, the

majority of the HVAC equipment appear to be original installs at past their typical life expectancy. The majority of assets are in very good to fair condition. Several pieces of equipment are newer and were brought online to treat the water supplied by GLWA in 2016.

In general, the majority of vertical assets rated in good-to-fair physical condition. There is ample redundancy in the system and several assets do not need to operate on a daily basis, therefore many of the assets exhibit a better physical condition than would be expected based on the age of the facilities. However, seven assets rated very poor and fifteen rated poor. These assets are listed below, with their reason for being scored poorly.

In general, the majority of vertical assets rated in very good performance condition. Given that the City does not have a CMMS, there was limited data to review for performance scoring. Additional feedback is need from the City to identify additional performance issues throughout the system. The scores indicate that the assets are currently meeting all capacity and regulatory requirements, have current state of the art technology, and have overall good performance. The twenty-five assets rated as “fair” were all electrical assets (motors, MCCs, transformers, switchgear, and panels).

Figure 12: Vertical Asset Performance Condition Summary
The assets which received poor performance condition scores were at the Flint Water Treatment Plant and include two broken unit heaters, and at Torrey Road Pumping Station and include two pumps, MCC 01, and a control panel. Pump 2 was out of service; pump 1 was in service at the time of the assessment, and had active leaks and bearing noise indicating failure was imminent. The MCC and control panel were deemed obsolete and had exposed wires. Overall, poor scores were due to obsolete design, unreliable performance, and O&M issues resulting from a lack of corrective work orders.

4.2 Consequence of Failure (COF) Factors and Scoring Scales The consequence of failure analysis is based on a triple bottom line (TBL) evaluation, which considers the economic, social and environmental consequences of a failure. Where applicable, the potential costs of failure are assigned to specific criteria within each TBL category to develop the best approximation of the overall potential cost. The following COF factors and scoring descriptions are presented below: Economic Consequence: The criteria and measures for evaluating direct economic impact considers repair costs and disruption to operations, including effort to repair (time, cost, and need for outside expertise) and impact to operations (loss of redundancy, impacts to upstream and/or downstream processes.) Environmental Consequence: The criteria and measures for evaluating environmental impact consider timing and magnitude of impacts to the environmental and regulatory violations. Social Consequence: The criteria and measures for evaluating social impact consider timing and magnitude of impacts to customers and stakeholders, including disruption of service and disruptions to the community.

4.3 Redundancy Redundancy is a specific measure in place to reduce the impact of an asset failure. In practice, risk mitigation can be achieved through any number of techniques including design measures such as redundancy and pump-arounds, operational measures such as diversions, heightened monitoring, and offline spares. A redundancy analysis was not performed as part of this AMP development; however, it is recommended for future updates to the AMP. The basic methodology for calculating redundancy is outlined below: For vertical assets, redundancy should be evaluated at peak operating conditions. For example, if three pumps are needed to satisfy peak demand and four are installed and functional, then one quarter of the pumps can fail with minimal consequence and the risk mitigation score is reduced from 1 by one quarter. Redundancy and redundancy factor are calculated using the following equation:
Redundancy = Number Installed – Number Needed Number Installed
Redundancy Factor = (1 – Redundancy)
For horizontal assets, redundancy can be applied on a case-by-case basis considering situations such as parallel water mains or multiple distribution paths to a service point.
4.4 Risk (Criticality) Factor Calculation The distribution system assets provide vital services to customers, and failure represents a unique risk to
the City from social, environmental, or economic ramifications. Through risk analysis, we can compare
the relative risks embedded in the system to make better resource allocation decisions. When assets
throughout the organization are scored using a consistent methodology, the calculated risk score
provides a common basis for comparison of a highly diverse collection of assets.
To calculate risk, the likelihood of failure score is multiplied by the consequence of failure score. If any
redundancy factor is available, it can be multiplied to reduce the overall risk.
The risk score is calculated using the following formulas for each asset type:
2017 WATER SYSTEM ASSET MANAGEMENT PLAN
arcadis.com 59
Horizontal Asset Risk Calculation: Risk = Max Likelihood of Failure x Max Consequence of Failure
Vertical Asset Risk Calculation:
Risk = Max Likelihood of Failure x Weighted Max Consequence of Failure x Redundancy Factor

Risk of both vertical and horizontal assets will be distributed on a scale of 1 (lowest risk) to 25 (highest
risk). Based on the risk score, assets are organized into one of five risk groupings: Highest (21-25), High
(16-20), Medium (11-15), Low (6-10) and Lowest (1-5). Using the assets relative risk ratings, projects can
be scoped and prioritized to address the greatest risks to the organization. The risk ratings serve as a
crucial communication tool to guide capital improvement planning efforts and O&M funding decisions.
4.4.1 Horizontal Asset Risk Summary
The following summary table illustrates that the majority of horizontal assets fell within the lowest risk categories (1-5 and 6-10). Less than 51 miles of pipe were designated as high risk (16-20) and less than 2 miles were scored highest risk (21-25).

Figure 19: Vertical Asset Risk Matrix
The following table includes the high-risk assets – Pumps 1 & 2 at Torrey Road Pumping Station, the Pump Station Building and Pump 1 at Cedar Street, and Pump 7 at Flint WTP. The assets below are high-risk because they are in poor condition and have a high consequence of failure. Several pumps have leakage issues, corrosion, steel/concrete support, and performance issues as well. In addition, the basement of the building at the Cedar Street Pump Station was flooded during the site inspection. Additional investigation is needed to determine the cause of flooding, if any equipment was damaged, or if there are any substructure issues. The consequence of these failures are high replacement costs and time (up to 24 hours) required to respond and repair the assets. High level summary information can be found in the table below, and full details can be found in Appendix C.

5.0 CAPITAL IMPROVEMENT PROJECT PLAN
5.1 Introduction to Horizontal Capital Planning Tool Arcadis used a GIS-based capital planning model that applies service level, criticality, condition, pipe deterioration curves and replacement cost criteria in conjunction with budget alternatives to plan for the R&R of linear assets. Various budget scenarios were modeled to show how the system-wide condition and risk change based on higher or lower funding levels. This allows for choosing the most appropriate long-term funding to achieve service level and risk goals.
5.2 Estimated Useful Life and Remaining Useful Life Estimated Useful Life (EUL) and Remaining Useful Life (RUL) are critical in supporting long-term capital and financial planning and asset management. EUL defines the total expected service life in years of an asset from the time it is commissioned, and RUL estimates the years of service life between the time of analysis and the time an asset is expected to need replacement. Years in Service is based on the install date of the equipment.
RUL = EUL – Years in Service
5.2.1 Horizontal Assets
As described in Section 4.1.1, the following table represents the Estimated Useful Life of the water main cohorts. The table list the number of segments, miles and percentage of pipe based on length within each cohort.

The asset’s effective useful life will be adjusted based on the assigned physical condition of the asset and the percent of its useful life already expended. This results in an adjusted effective useful life for each asset based on physical condition. By subtracting the asset age from the adjusted effective useful life, a more realistic remaining life can be calculated for each asset. The adjusted useful life calculations based on physical condition and expended useful life are provided below.

5.3.2 Vertical Assets
Replacement costs were developed for vertical assets that are recommended to be replaced in the next five years. For electrical, mechanical, and HVAC assets, replacement costs were estimated and for structural assets, repair costs were estimated using the following methodology:
1. Review existing drawings and asset photos where available. 2. Estimate replacement costs using RS Means Cost Works as a guide where asset class and
capacity is available for assets (such as fans, generator, pumps, large motors, boilers, hoists, panels, small valves etc.)
3. Estimate replacement costs for large assets based on project experience and historical pricing information for assets (such as MFP’s, switchgear, large valves, etc.)
4. Include demolition, material cost, installation, and start-up costs. 5. Escalate replacement costs by a factor of 1.4 to account for Level V cost estimating that assumes
30-50% contingency. 6. Escalate the costs for overhead and profit by a factor of 1.21, to arrive at installation cost. (The
total markup for the RS Means assumption is 1.694.)
A recommendation for future versions of the AMP involves creating asset-level cost estimates for all assets.
5.4 Capital Planning Model Configuration and Scenario Results
5.4.1 Horizontal Assets
The model considers the pipes for replacement that meet the following thresholds defined in the table below. For example, for a pipe with the highest COF score of 5, the model considers that pipe for replacement when it reaches a break rate of 60 or has a performance score of 4 or higher. Conversely, a pipe with the lowest COF would not be considered for replacement until it reaches a break rate of 80 or a performance condition of 5. Each year, every pipes’ break rate will increase, but their performance score will stay constant until they are replaced, at which time the performance changes to a 1. For each year, every pipe that meets the thresholds identified below are eligible for replacement.
Table 49: Thresholds for R&R
COF Description Break Rate Performance Score
1 Lowest 80 5
2 Low 75 5
3 Medium 70 5
4 High 65 4
5 Highest 60 4
The model was configured to allot 20% of funding to high risk pipes and 80% of funding to those in the worst condition (high LOF score). For example, in 2018, $12 million was budgeted for water main replacement. Therefore $2.4 million went to replace the highest risk pipes and the remaining $9.6 million
2017 WATER SYSTEM ASSET MANAGEMENT PLAN

was used to replace the worst condition pipes. This configuration ensures that the highest risk pipes due to poor performance scores are replaced, while still applying funds to minimizing the rising overall break rate. Four funding scenarios were run based on this configuration. All three scenarios start with the previously planned funding of $12M in 2018, $19M in 2019 and $7M in 2020. Scenario 1 is also based on the previous plan which allocated a constant $5M per year from 2021 through 2037. Scenario 2 increased funding by $0.5M each year starting at $7M in 2020 and finishing at $15.5M in 2037. Scenario 3 increased funding by $1M each year starting at $7M in 2020 and finishing at $20M in 2037. Scenario 4 increased funding by $2M each year starting at $7M in 2020 until reaching and holding $21M per year from 2027 through 2037. For comparison the initial 2018 system-wide average scores by length are:

% Max Risk
33.95 2.16 3.00 3.17 2.25 2.25 11.25 7.18 54.8%
The overall minimum possible system wide risk of 2.25 would occur if every pipe was new and therefore had an LOF score of 1. Conversely the maximum possible system wide risk of 11.25 would occur if every pipe was at end of useful life with an LOF score of 5. The initial 2018 system wide risk of 7.18 therefore represents (7.18 – 2.25) / (11.25 – 2.25) = 4.93 / 9.0 = 54.8% of maximum risk. The following table shows how the break rate, physical condition, performance condition, overall LOF, and risk change by the end of each scenario. All scenarios show an increase in break rate and thus the physical condition, but the performance condition shows marked improvement in each scenario. This is primarily because almost 47% of the water mains have initial performance scores of 4 or 5. Scenario 1 increased physical score overwhelms the improved performance score, resulting in an increased risk score. The better physical scores of Scenarios 2, 3 and 4 along with the reduced performance scores result in a risk reduction as shown in the table below. The results of all four scenarios are shown in Appendix D.

Scenario 3 represents the recommended funding scenario. It includes an aggressive ramp up of water main replacement as shown in the following figure. Over 20 years, $310M is spent to replace 198 miles of water mains. Although the system wide break rate increases initially, it levels off and reduces to under 40 breaks per 100 miles per year. Scenario 3 Risk is gradually reduced almost every year in the plan.
Figure 20: Scenario 3 Water Main Replacement Costs, Break Rate, and Risk
The following graph shows the Risk Matrix (length of pipe by COF and LOF) for the initial and final year of the plan. These graphs show the length of pipe by LOF within each of the five COF groups. The goal is to minimize the amount of high LOF pipe in the high COF groups. The initial risk profile in 2018 shows 7.56 miles of LOF 4 and 5 in the COF 5 group. There are also 44.46 miles of LOF 4 and 5 in the COF 4 group. By 2037, there is no LOF 5 and only 0.53 miles of LOF 4 in the COF 5 group. The COF 4 group has been reduced to 11.75 miles of LOF 4 and 5 pipe, with almost none of it being LOF 5. Therefore, the miles of pipe in the two highest Risk groups will be reduced by 75% from over 52 miles to less than 13 miles.

5.4.2 Vertical Assets
The City of Flint has a Capital Improvement Plan in place for FY2018 through FY2022. The LOF, COF, and risk evaluations for vertical assets yielded twenty-four assets that are recommended to be replaced within the next five years based on risk, present condition, and remaining useful life. The following chart indicates the number of assets to be replaced in the following increments, based on the risk and RUL analysis: 0-2, 3-5, 6-10, 11-20, and 20+ years. All critical assets are included for replacement in the first five years.
Figure 22: Assets Replacement based on RUL
Installation cost was estimated based on the methodology outlined in Section 6.3.2, for the twenty-four assets recommended to be replaced or repaired in years 1-5. For mechanical, electrical, and HVAC assets, complete replacement was considered at the end of the asset’s useful life; and for structural, repair, not complete replacement, was considered in the analysis. CIP Group 1 includes R&R of assets with an RUL from 0 up to 2; CIP Group 2 includes R&R of assets with an RUL 2 up to 3; CIP Group 3 covers assets with RUL 3 up to 4; CIP Group 4 covers RUL 4 up to 5 and CIP Group 5 covers RUL 5 up to 6. A total investment of almost $2M is required to rehabilitation/replace these assets over the next five years, as illustrated in the chart below. Based on discussions with the City, there is a line item included in the current CIP line item for “Pump Station Improvements” that could potentially cover the anticipated replacement needs. If it is determined that the anticipated replacement needs ($2M) for the first five years are not addressed in the current CIP, then the financial model will need to be adjusted accordingly

* It is assumed that the approximately $2M in anticipated vertical asset R&R is addressed in the current “Pump Station Improvements” CIP line item, so no additional investment is shown here for vertical assets. If this is not the case, the financial model will need to be adjusted accordingly to include the anticipated investment for vertical assets.
It is estimated that the completion of the following projects will be the end of their corresponding fiscal year.
5.6 20-Year CIP The investment in horizontal assets, based on the recommended capital model scenario outlined in Section 6.4, will require $1M additional funding each year to replace poor condition, high risk pipes. Therefore the 20-year CIP will include $1M increases each year as listed in the table below, ending at $24M in 2037. The total investment in horizontal assets R&R is $310M, with a total of approximately 200 miles replaced. For vertical assets, the 5-year CIP is assumed to be addressed in the Pump Station Improvements CIP line item, so no additional investment is shown for the 5-year period. Beyond the 5-year CIP, an average R&R rate of 3% was estimated based on the overall replacement cost of the pump stations. The 3% reinvestment rate is based on an estimated useful life for a pump station of 30 years.

5.7 CIP Funding Gap Discussion As noted above, Scenario 3 is the recommended Asset Management Plan for the City. The financial analysis in Section 6 of this Report outlines the analysis that determines the estimated funding gaps, as well as the revenue increases needed to meet the following:
Annual O&M expenses, including water system operation and maintenance and annual payments for water service.
Cash Funded Capital – This includes annual amounts to fund the cash portion of the City’s CIP, and annual replacement amounts for Scenario 3 for horizontal and vertical assets.
Reserve Balances – This includes transfers to or from the available Operating Fund balance. The City targets for the Water Fund to maintain 25 percent of the annual expenditures for O&M and debt service, and Transfers to the General Fund.
The following chart reflects the funding gap for implementing the Scenario 3 Asset Management Plan
2017 WATER SYSTEM ASSET MANAGEMENT PLAN
arcadis.com 79
Figure 24: Funding Gap Summary
To close the funding gap, the City will need regular increases to its water system rates and charges. This includes the annual increases noted in Table 67 of Section 6.4. The percent increases needed assume that the City will fund the annual Scenario 3 requirements from water system operating revenues. The City has indicated that it will be extremely difficult to undertake the revenue increases necessary to implement the Scenario 3 plan. As such, it will pursue various other funding sources such as state and federal grants to offset the funding gap. At this time, the 5-year CIP includes significant funding from grant sources. Beyond FY 2022, it is not clear how much grant funding might be available for the City’s water system, and therefore the financial analysis assumes cash funding of the future replacement capital per Scenario 3. The City could also attempt to pursue future revenue bonds or SRF loans to offset some of the Scenario 3 replacement capital. In recent years the City retired its outstanding debt service, and this Asset Management Plan does not reflect a plan for the City to issue debt or take advantage of SRF loans. If available and if desired by the City, these mechanisms could push revenue increases to future fiscal years and mitigate revenue increases once the replacement capital ramp up begins. Once water system operations and business functions are stabilized, the City may be able to consider using state revolving fund loans or revenue bonds to fund a portion of the future horizontal asset R&R. This would result in a lower level of total revenue requirements over the 20-year period to the benefit of current ratepayers.

6.0 REVENUE STRUCTURE An effective AMP requires a corresponding financial plan to ensure that the City understands the necessary funds for performing operations and implementing the capital improvements. Arcadis completed a financial plan that is based in part on a rate study currently being performed by the City and another consultant. The City’s rate study projections to FY 2026 serve as the baseline projection for revenue under existing rates and revenue requirements such as operation and maintenance (O&M) and cash funded capital. Arcadis then incorporated the capital improvement recommendations outlined in this report, and extended the financial plan to a 20-year projection through FY 2037. The financial plan calculates the estimated revenue increases that are required for the City to meet the projected operating budget and capital costs, including the capital plan recommendations outlined in this report. The following sections outline the financial projections developed as part of this asset management plan, including an overview of the City’s revenue structure, its operating budget, anticipated annual capital improvements, and the estimated annual revenue increases from rates and charges needed to implement the plan.
6.1 Water System Revenue Under Existing Rates The City has developed a projection of revenue under existing rates and charges for the water system. The following sections provide an overview of the projected revenue under existing rates and charges.
6.1.1 Existing Rate Structure
The legal basis for setting the City’s water rates is found in the City of Flint Code of Ordinances. Chapter 46-52.1 outlines the City’s requirement to calculate and transmit a new schedule of water rates on or before April 15th of each year. The City submits a budget each year that includes a schedule of rates and charges for the water system. The City Council reviews and adopts the annual budget, including the underlying schedule of water system rates and charges. The City’s existing water rate structure consists of a monthly fixed service charge graduated by meter size, and a declining block volume charge. The City has separate rates and charges for customers that reside within the City limits and customers that reside outside of the City limits. The following presents the City’s existing rates and charges for general water service.
Table 56: Monthly Water Service Charge

Inside City Outside City Residential Non-Residential Residential Non-Residential
1st Block 0 to 35 Ccf $ 6.187 $ 6.187 $ 9.285 $ 9.285
2nd Block 36 to 2,000 Ccf $ 5.835 $ 5.835 $ 8.939 $ 8.939
3rd Block Over 2,000 Ccf $ 4.755 $ 4.755 $ 7.140 $ 7.140
Arcadis did not perform a detailed cost of service study and rate design for this AMP, however, the rate structure used by the City is common within the water industry. The graduated monthly service charge by meter size (Table 56) reflects the relatively higher cost incurred by water utilities for operation and maintenance and capital replacements of larger connections and meters. The declining block rate structure (Table 57) is also common. It is generally used by communities to recover system costs from a variety of customer types, e.g., residential, commercial, multi-family, and industrial. The blocks and associated rates are typically designed to recover each class’ respective cost of service.
6.1.2 Projected Accounts and Volumes
The City has developed projected water system accounts and usage volumes for the period FY 2018 to FY 2026. The City’s basic assumptions related to the number of water accounts are shown in the following Table for the 5-year period FY 2018 through FY 2022:
Table 58: Projected Water Accounts

TOTAL 30,848 30,848 30,848 30,848 30,848
As the table reflects, the City projects the number of Inside City and Outside City customers to remain stable for the foreseeable future.

As is seen the total billed volume shows a decrease from year to year. This reflects the City’s estimate that Residential and Non-Residential billed volume will decrease by 2.0 percent per year to FY 2026 to reflect a general trend in the water industry of declining water consumption. Beyond FY 2026, it is assumed that the per capita consumption will then remain stable.
6.1.3 Projected Revenue Under Existing Rates and Charges
Arcadis applied the existing water rates and charges to the projected monthly billings and billed volume to derive an estimate of revenue under existing rates and charges. The following Table presents the estimated water revenue under existing rates and charges.

A significant issue for the City is the estimated revenue collection factor, particularly for the Residential customers. For FY 2018, it is estimated to be 65 percent of billings. This results in less revenue available to meet system revenue requirements. The City estimates that the collection factor will improve to 85 percent by FY 2022 for Residential customers.
6.1.4 Miscellaneous Revenue
The City also maintains fees and charges for miscellaneous services provided. These include fees and charges related to activities such as water turn on/off services; meter testing requests; and other miscellaneous services, as well as interest income. The City estimates that miscellaneous revenue will be approximately $1.2 million per year.
6.2 Water System Revenue Requirements The City’s revenue requirements generally consist of:
1. Operation and maintenance expenses necessary to provide the labor, materials, and supplies required to provide drinking water to the citizens of Flint.
2. Capital-related expenditures to design and construct the necessary water system improvements, as well as provide funds for the normal renewal and replacement of water system assets as they reach the end of their useful life. This would include any debt service or loan payments should the City determine to fund capital improvements with debt.
3. Operating reserves to ensure the City has sufficient funds on hand to adequately fund system operations should unanticipated revenue shortfalls or expenses occur.
6.2.1 Operation and Maintenance Expenditures (OpEx)
The water system projected OpEx are derived from the FY 2018 and FY 2019 Adopted Budget, which includes the operating budget approved by the City Council for the water fund. The following Table reflects the Adopted Budget for the Water Fund for FY 2018 and FY 2019. The Table also reflects adjustments made by the City to better reflect anticipated O&M expenditures since the budget was adopted. These adjustments are related to the City’s determination that it will obtain finished drinking water from the Great Lakes Water Authority (GLWA) in lieu of treating water at its own treatment plant.

As can be seen, the City expects water OpEx to be approximately $28.8 million and $30.9 million for FY 2018 and FY 2019, respectively. Significant OpEx is related to the City’s contractual obligations for water supply. Utilities Administration includes approximately $7.0M in FY 2019 for the payment of annual debt service related to the Karegnondi Water Authority’s (KWA’s) project to supply raw water from Lake Huron. Water Plant Operations includes approximately $5.7M in FY 2019 for the annual payment related to GLWA’s supply of finished water to the City. The annual bill from GLWA will be $12.7M with $7.0M going to a trust for the KWA bond payment. To estimate the future OpEx for the water system, the City anticipates OpEx categories to generally increase on an annual basis. The following reflect annual cost escalation factors used to project OpEx to FY 2026.
Salaries, Wages, and Benefits - 3.0%
Pension - 5.0%
Materials and Supplies - 3.0%
Power - 4.0%
GLWA Supply Costs - 5.0% The following Table presents the projected OpEx for the water system by operating unit. The Table shows that water system OpEx is projected to increase from approximately $28.8M in FY 2018 to $33.6M in FY 2022. This reflects an average annual increase in OpEx of 3.9% for the 5-Year projection period.

6.2.2 Capital Expenditures (CapEx)
The City has significant capital improvements planned for the 5-Year and 20-Year projection period. The following Table presents the City’s projection of capital improvements for the period FY 2018 to FY 2022. Column 6 of the Table reflects how the City anticipates funding these capital improvements. The current plan calls for using either available grant funding or cash from water system revenues. The City does not anticipate issuing any revenue bonds or loans from state revolving fund (SRF) programs.

As can be seen in the Table above, the City anticipates meeting significant capital needs from state and federal grants. This requires the amount seen on Line 17 to be funded from operations, and is accordingly included as part of the water system annual revenue requirements. Line 6 reflects the results of the Scenario 3 Asset Management Plan recommendation for horizontal assets. The Scenario 3 recommendations for additional replacement of vertical assets is set to begin in FY 2023 at approximately $200,000 per year.
6.2.3 Total Revenue Requirements
The following Table summarizes the annual revenue requirements for the water system from the above sections.

6.3 Additional Revenue Required to Close Funding Gap To meet the revenue requirements above, the City will require additional water rate increases. The Table below presents the total revenue requirements, offset by 1) other miscellaneous revenue; 2) interest income; and 3) transfers to and from the operating balance to supplement revenue or maintain targeted operating balances per City policy. The City’s policy is to maintain an operating fund balance that is equal to 25% of the operating budget and annual debt service expenditures. At the beginning of FY 2018, the City anticipates that approximately $15,577,700 will be on hand for the Water Fund.

As is seen, the projected net revenue requirements from rates and charges (Line 4) are projected to increase to approximately $42.7 million by FY 2022. This is more than the projected revenue under existing rates and charges seen in Table 66. To close the gap between projected revenue requirements and revenue under existing rates, the City would need annual rate increases beginning in FY 2019. The following Table reflects the planned rate increases and additional revenue to meet the projected revenue requirements. It is assumed that any revenue increase is implemented to recover a full year’s worth of revenue with increased rates and charges.

As can be seen, the City would require revenue increases to water rates and charges seen in Lines 2 through 6. This produces revenue from rates and charges that increases to approximately $42.7 million by FY 2022. Combined with Miscellaneous Revenue (Line 8) it produces Total Revenue (Line 9) to meet the projected revenue requirements (Line 10). The difference (Line 11) reflects sources and uses of Operating Funds on hand to maintain a targeted Operating Fund balance that is equal to 25 percent of annual O&M and any debt service. In this instance, the ending balance (Line 13) by FY 2020 approximates 25 percent of annual O&M expense as the water system currently has no outstanding debt service.
6.4 20-Year Projection For the 20-year projection, the increasing rate of replacement for horizontal assets, combined with annual replacements for vertical assets, will continue to require additional funding from the City. The following Table presents the projected revenue, revenue requirements, and necessary revenue increases to close the funding gap.

Note: Minor variances in summations due to rounding
As can be seen in Column 9, the City will require regular, annual increases from rates and charges to meet its projected O&M expenses, fulfill capital improvement requirements (including the recommendations in this Asset Management Plan), maintain an Operating Fund balance of 25 percent of O&M and debt service. The cumulative revenue derived from the increases above will provide the necessary revenue to offset the annual gaps seen in Column 8.
6.5 Mitigation of Revenue Increases The percent revenue increases noted above are considered to be a conservative estimate. The City has several ongoing initiatives that should mitigate the increases, including:
The promotion of more efficient operations/staffing over time to reduce costs and improve performance of the water system
Improved revenue collections from customers resulting from the implementation of the City’s shut off policy
Enhancement of low income assistance programs
2017 WATER SYSTEM ASSET MANAGEMENT PLAN
arcadis.com 91
Use of alternative rate design to address affordability for customers that use a minimal amount of water
There are other areas that would offset the conservative revenue increases noted above. This includes the continued pursuit of state and federal grants to offset a portion of the projected renewal and replacement capital over the 20-year projection period. If feasible, and if desired by the City, consideration should also be given to using SRF loans or other similar mechanisms to finance a portion of the future renewal and replacement capital. This would help to push rate increases further into the future to the benefit of Flint’s current customers. Finally, the revenue requirements are based on the CIP which includes cost estimates based on a conservative, open-cut method for the replacement of the distribution system. If feasible, other, less expensive methods of rehabilitation should be considered to reduce the financial burden for the City and its customers. Arcadis recommends that the City continue with regular financial planning to appropriately incorporate the results from the areas and initiatives mentioned above. Any benefits in terms of cost savings or revenue enhancement can be factored in to the financial plan, providing future, mitigated rate increases for customers.

7.0 FY2017 YEAR-END REPORT The City of Flint began a Drinking Water Optimization Project in 2017, which included the development of an MDEQ compliant Asset Management Plan. This year, the City’s preparation to submit the AMP has included the following efforts:
Development of Levels of Service measures
Development of methodologies to score likelihood and consequence of failure for horizontal and vertical assets, and how to calculate risk.
Review and update of GIS inventory data.
Condition assessment of vertical assets at pump station and water treatment plant facilities.
Configuration of Capital Planning Model, scenarios, and development 20-year CIP plan
7.1 Asset Inventory Summary The following summary tables detail the progress made to date in identifying the City’s water distribution system assets. The intent is use these tables to track and show progress with each yearly AMP update.
7.1.1 Horizontal Assets
The GIS horizontal asset inventory, detailed in Section 2.2.1, includes 582 miles of water main, 3,604 hydrants, 9,577 valves, and 16,656 fittings. A data profile analysis was performed to determine the completeness of the fields in the GIS database tables. The fields were summarized as to percent populated, zero, or negative. Many data gaps were identified through this process and recommendations are detailed in Section 2.5.2.1. Key attributes for water mains and their profile results are detailed below; the complete data profile results are summarized in Appendix E.
Table 68: Horizontal Assets - Inventory Summary for Water Mains
Key Attribute % Populated % Zero % Negative
Diameter 100% 0% 0%
Material 100% - -
Install Date 1% 0% 0%
Length 100% 0% 0%
To resolve the low percentage of install dates populated in the GIS, data gaps were closed by using pipe replacement project dates, using hydrant fabrication year dates, and using install dates based on adjacent pipes.
7.1.2 Vertical Assets
The City performed a condition assessment on 160 assets at four pumping facilities listed below; the five storage facilities were not condition assessed at this time. However, all facilities have been inventoried with respect to MDEQ requirements. The City can increase the number of attributes collected, as well as the LOF, COF, and Risk scores in future updates of the AMP.

7.2 Detailed Expenditures The City of Flint experienced a drinking water crisis in 2014, and has since been operating in crisis-mode with a very reactionary approach to rehabilitation and repair. The table below reflects that in FY2017, no dollars were invested in pipe replacement or facility improvements. The City intends to move to a more proactive approach going forward in FY2018-FY2022.
Table 70: Expenditures for FY2017
Estimated Cost Comment
Pipe Repair TBD To be provided by City of Flint
Pipe Replacement 0 No investment made in FY2017
Facility Expenditures – Capital Investment
0 No investment made in FY2017
Corrective Maintenance TBD Future measurement when CMMS is implemented
Preventative Maintenance TBD Future measurement when CMMS is implemented
While the City of Flint did perform Corrective Maintenance and Preventative Maintenance activities in 2017, it is difficult to track given the current lack of CMMS program. In future updates to the AMP, hours for both CM and PM should be summarized, along with the cost for each, by asset class.

CIP Utilize current CIP, with additional recommendations for vertical and horizontal
R&R as outlined in Section 5.
Revenue Structure
Factor the results of this Asset Management plan into the City’s internal budget discussions.
Recommend relevant increases to water rates and charges as part of the annual budget process.
Continue to pursue alternative grant funding sources to offset projected vertical and horizontal R&R as outlined in Section 6.
8.2 Alternative Pipeline Renewal Approach Currently the R&R budget is conservatively estimated based on open-trench construction. Determining the appropriate pipeline renewal approach will significantly influence the City’s R&R planning and budget. Before employing a replacement or rehabilitation method, determining the structural condition of the water main is necessary. Evaluations can range from simple and inexpensive to high-tech and costly. Examples of successful methods for determining pipeline renewal approach include leak/break performance,
2017 WATER SYSTEM ASSET MANAGEMENT PLAN
arcadis.com 95
sample extraction/evaluation, and in-situ testing. Several variables impact the cost of water main renewal including, but not limited to project size, pipeline diameter, renewal method, bypass requirements, MOT, and number of service lines, valves, and fittings. Depending on the renewal method, the cost could be between 25 percent and 100 percent of conventional open-trench construction. The pipeline renewal approach analysis should include direct contracting and related costs, as well as indirect costs associated with public disruption, longer-term maintenance, and other life-cycle costs. Arcadis performed an extensive field effort in support of recalibration of the City’s hydraulic model in May 2017. The flow tests indicated severe degradation of the tested piping, which could limit pipe renewal options. Due to the current condition of the pipes and projected R&R need, the City should evaluate rehabilitation options versus traditional open-trench construction. By selecting an alternative rehabilitation technology, the City could potentially reduce the projected R&R needs and allow for the City to replace more pipes over the 20-year period. Upon completion of the Distribution System Optimization Study, the City should update this AMP to reflect the selected optimal operating scenario.

MDEQ Asset Management Guidance for Water Systems
1 July 2013
Asset Management Guidance for
Water Systems
What is Asset Management? Water systems are made up of assets; some are buried assets and “invisible,” while the rest are visible. These are the physical components of the system and can include: pipe, valves, tanks, pumps, wells, hydrants, treatment facilities, and any other components that make up the system. The assets that make up a water system lose value over time as the system ages and deteriorates. As the assets deteriorate, the level of service the utility’s customers desire may become compromised, operation and maintenance (O&M) costs can increase, and the utility may be faced with excessive costs it can no longer afford. There is an approach to managing the assets of the system that can assist the utility with making better decisions on caring for these aging assets. This approach is called asset management. The International Infrastructure Management Manual defines the goal of asset management as meeting a required level of service in the most cost-effective way through the creation, acquisition, operation, maintenance, rehabilitation, and disposal of assets to provide for present and future customers. A water utility has a responsibility to manage its assets in a cost-effective manner for several reasons:
1) these assets represent a major public investment
2) well-run utilities are important to economic development
3) proper operation and maintenance of a utility is essential for public health and safety
4) utility assets provide an essential customer service
5) asset management promotes efficiency in the operation of the system
6) properly managing the assets is the basis of self-sufficiency
The intent of asset management is to ensure the long-term sustainability of the water utility. By helping a utility manager make better decisions on when it is most appropriate to repair, replace, or rehabilitate particular assets and by developing a long-term funding strategy, the utility can ensure its ability to deliver the required level of service perpetually.
Asset management is a set of procedures to manage assets through their life cycles, based on principles of life cycle costing. These procedures, to be effective, must be implemented in a programmatic way. Properly practiced, it involves all parts of the organization and entails a living set of asset performance goals to implement asset management. An Asset Management Plan is a tool to help the utility implement its Asset Management Program.
Core Components of an Asset Management Plan
Typically, there are five core components in an Asset Management Plan:
1) Asset Inventory
2) Level of Service
3) Critical Assets
2 July 2013
4) Revenue Structure
5) Capital Improvement Project Plan
As part of this guide, the Michigan Department of Environmental Quality (DEQ) has developed an Asset Management Plan Workbook. This workbook is in Excel and can be used as an active asset management tool or as a guide for what an asset management plan can look like.
Effective asset management implementation is comprehensive. It may involve integrating a number of tools along with other existing systems (accounting, financial reporting, purchasing and stores, payroll, etc.) to create a comprehensive information system that will support an integrated Asset Management Program. An Asset Management Program will have a Mission Statement. This Mission Statement defines the program.
The following is an example of a Mission Statement:
We commit to improving and maintaining the public health protection and performance of our drinking water plant and distribution utility assets, while minimizing the long-term cost of operating those assets. We strive to make the most cost-effective renewal and replacement investments and provide the highest-quality customer service possible.
A DEQ-approved Asset Management Plan will include a Mission Statement and list Asset Management Team members. A Mission Statement should be an overarching purpose for maintaining an Asset Management Program. Consider the impacts to public health, your ability to comply with regulations, and financial stability if you do not manage utility resources. An Asset Management Plan will have short-term and long-term processes to evaluate current conditions and revise/update as needed. It will also contain an Action Plan that identifies actions needed to make improvements and meet goals.
When assembling an Asset Management Team, consider current and past municipal staff (officials, board members, clerks, accountants, and engineers), current and past utility staff (operators and other service workers), and any other stakeholders that can help in assembling the information to develop your Asset Management Plan. Asset Inventory The first core component of asset management is the asset inventory. This component is probably the most straightforward of all. It is also, arguably, the most important and time consuming. Questions that the utility will ask itself in this component are:
• What do I own?
• Where is it?
• What condition is it in?
• What is its remaining useful life?
• What is its value?
What do I own?
The most fundamental question a utility owner, manager, or operator can ask is, “what assets do I have?” It is absolutely critical for a utility to understand what it owns. It is difficult to manage something effectively if you don’t know what that “something” is. However, this is not
3 July 2013
an easy question to answer: some assets are underground and can’t be seen; assets generally are put in at different times over a long period of time; records regarding what assets have been installed may be old, incomplete, inaccurate, or missing; and staff turnover in operations and management may limit the historical knowledge of system assets. Because of these difficulties, doing a complete asset inventory on the first try may not be possible. It is important to recognize that asset inventory is an ongoing process. To develop the initial inventory, there are a number of resources a utility can draw upon such as as-built drawings, invoices, staff knowledge, visual observation, interviews with residents and consultants. A utility should use as many approaches as it deems necessary to get the best initial inventory of assets. Information on each asset may include the manufacturer, original price, and category (i.e., distribution, collection, storage). Where are my assets? Once you know what you have, it is important to know where the assets are located. This involves two steps:
1) connecting the asset in the inventory to a specific location
2) mapping the assets
The first step is to connect the asset with a location. The location could be a street name, street address, or building location such as pump house or treatment building. The addresses should be as specific as possible; that way, assets can be grouped together based on their asset type, such as all hydrants on Main Street.
Mapping will provide a visual picture of the asset locations, especially buried assets. The map can be as simple as a hand drawn map or as complex as a Geographic Information System (GIS) map.
What is the condition of my assets?
After the assets have been identified and located, it is important to know the condition of the assets. A condition assessment can be completed in many different ways, depending on the capability and resources of the utility. The simplest way is to assign a numerical ranking to each asset. This approach uses the best information available. Below is an example of a ranking system.
Condition Assessment
Condition Rating Description
5 Unserviceable
4 Significant Deterioration
3 Moderate Deterioration
2 Minor Deterioration
1 New or Excellent Condition
If resources are available, a higher level of assessment could include leak detection for water pipes.
4 July 2013
What is the remaining life of my assets?
All assets will eventually reach the end of their remaining useful lives. Some assets will reach this point sooner than other assets. There are many factors that will affect the useful life of an asset such as maintenance practices, type of materials, usage, and surrounding environment. Useful life will also vary over time; for example, a pump may originally have been assigned a useful life of 15 years, but with proper maintenance that useful life may extend to 20 years. Useful life should be reevaluated on a regular basis. Past experience, system knowledge, existing and future conditions, and maintenance practices will dictate ongoing changes/updates to the useful life.
What is the value of my assets?
The value of the asset is the cost to replace the asset after it has exhausted its useful life. Obtaining costs for the asset replacement is not easy. In some cases, the utility will use an estimate based on best practices; in other cases, the utility may rely on a consultant or manufacturer’s catalogs and sales representatives. More reliable data can be added when available.
Organizing the Asset Inventory/Summary There are many options regarding how to manage the asset inventory data. There are commercial and open-source software options available as well as the opportunity for a utility to create its own database for asset inventory. The key to any asset inventory is that the data is comprehensive, accessible, and there is a means to safeguard the data. It is important to develop at least a rudimentary asset inventory with all of the characteristics discussed above. The data quality can be increased over time as the system gathers more information and the Asset Management Team becomes more comfortable with the concept of asset management.
It is critical for utilities to understand that asset inventory is an ongoing process. Over time, assets will be added and deleted from the asset inventory. Utilities should also be careful to not let themselves get “bogged down” in the asset inventory component. Asset inventory, while critical, should not be all consuming. As time goes on, a utility should consider ways in which it can make the inventory more sophisticated. As an example, a system may want to develop a GIS map and database or add radio frequency tagging of the assets for tracking purposes.
Using the Asset Inventory Tab
An Asset Inventory Tab has been included as part of the Asset Management Workbook. This Excel spreadsheet allows users to input data in each of the cells. The spreadsheet lists assets in column A and can be expanded by inserting any additional number of desired rows. More columns can be added to expand the number of asset identifiers such as serial number or date installed. Columns for Probability of Failure and Consequence of Failure perform mathematical functions to determine the Criticality Factor and should not be used to enter data. The forthcoming section on Critical Assets will provide information on inputting data into cells.
Level of Service Level of Service (LOS) defines the way in which the utility stakeholders want the utility to perform over the long term. The LOS can include any technical, managerial, or financial components the utility wishes, as long as all regulatory requirements are met. The LOS will become a fundamental part of how the utility is operated.
The best way to understand LOS may be to think of a worst case scenario. Imagine a water system that struggles with constant water main breaks, a water tower in need of painting, low- water pressure, has inaccurate billing numbers due to water meters over 30 years old, and has
5 July 2013
no idea how to start addressing their problems. Because of these issues, the water system has difficulty with compliance and receives customer complaints regularly, even though water rates are low. The LOS for this system would be considered low.
All utilities must operate within the state and federal regulations and requirements. These regulations are generally specified in the Safe Drinking Water Act for water systems, but there are additional rules and regulations at the state and federal level. Although the state and federal regulations set bare minimum standards of operation in the LOS, these standards will not adequately address all areas of operation and should not be the sole factor of the LOS. Utilities should include many other factors to delineate important areas of the utility’s operation.
Within the range of the minimum (regulations) and maximum (absolute capabilities of assets), there are numerous items a utility could include within its LOS. Items may be included so the utility can communicate its intentions with its customers, measure its performance, and determine critical assets. Understanding what LOS to choose will help in developing an Asset Management Plan that truly captures the utility’s performance and how to accomplish future goals.
It is important for the utility to communicate with its customers to avoid confusion, bad feelings, accusations of improper operation, and to make clear what the customer’s expectations should be. This need for communication is particularly important for smaller, rural systems, but it is important for all systems. The Asset Management Team should develop a LOS Statement to help focus efforts on what an Asset Management Plan should accomplish and how to be most cost effective while meeting customer expectations and complying with state and federal regulations. The LOS Statement should address the service areas, identify any deficiencies, and set goals for improvement.
Defining the LOS sets the goals for the utility. These goals allow the operations staff to have a better understanding of what is desired from them, and the management has a better understanding of how to use staff and other resources more efficiently and effectively. Reviewing how the utility is meeting LOS also allows the management to shift resources if needed from one task to another to meet all the goals most effectively. Understanding the desired LOS will help to prioritize and characterize the system’s assets, as well as how to manage finances to reach the LOS goals.
There is a direct link between the LOS provided and the cost to the customer. When a higher LOS is provided, costs to provide that higher level will likely increase. This direct link demands that the utility have an open dialogue with its customers regarding the LOS desired and the amount the customers are willing to pay for this LOS or increased services.
Ideally, the public or customers of the utility would be actively involved in the development of the LOS. Similar to the overall Asset Management Plan that will change and adjust over time, the LOS may need to be adjusted from time to time. This adjustment may be required because the system may discover that it is too costly to operate the system at the levels previously defined. Or the adjustment may be necessary due to new rules or regulations that require a change in operation. Additionally, the customers may feel that they desire a different level of service. As with all components of asset management, LOS is an ongoing process and determining and detailing the level of service that the system is going to provide is a key step in asset management.
6 July 2013
Typical questions to consider when developing the LOS for the system:
1) What is the LOS goal for health, safety, and security?
2) How often is the system out of compliance with regulations?
3) Are the operators properly certified?
4) How does the utility stay aware of and prepare for new regulations?
5) Do you share your LOS statement with your customers?
6) How do you track and respond to customer needs/complaints?
7) Can the current process be improved?
8) How quickly does the utility respond to customer issues?
9) Is maintenance being deferred to save money?
10) How much will the improvements cost and how will they be funded?
11) Are assets being properly maintained to insure they are in reliable working condition?
12) What areas within the system are most important to insure the best LOS possible?
13) When considering a preferred LOS, are asset age and life cycles, asset conditions, funding availability, etc. being factored in?
14) How often will the LOS statement be reviewed in order to capture changes such as funding availability (growth and decline), regulatory requirements, demand of customers (increases/decreases in customers), and physical deterioration of assets (addressing water loss/maintenance)?
15) Are O&M activities being maximized to meet the LOS goals?
Critical Assets Not all assets are equally important to the utility’s operation. Some assets are highly critical to operations and others are not critical at all. Certain assets or types of assets may be critical in one location, but not critical in another. For example, a well pump serving the downtown area may be deemed more critical than a well pump servicing an industrial park under construction. A utility must examine its assets very carefully to determine which assets are critical and why.
Determining Criticality
In determining criticality, two questions are important. The first is how likely is it that the asset will fail; and second, what is the consequence of failure? Determining an asset’s criticality will allow a utility to manage its risk and aid in determining where to spend operation and maintenance dollars and plan capital expenditures.
To determine the probability of failure a utility needs to look at a number of factors: asset age, condition of asset, failure history, historical knowledge, experiences with that type of asset in general, maintenance records, and knowledge regarding how that type of asset is likely to fail. Below is an example of a ranking system for probability of failure.
7 July 2013
Probability of Failure Levels
Description Performance Rating
Failure of Individual Item Type of Failure
Imminent 5 Likely to occur in the life of the item
Continuously experienced
Probable 4 Will occur several times in the life of an item
Will occur frequently
Occasional 3 Likely to occur sometime in the life of an item
Will occur a few times
Remote 2 Unlikely but possible to occur in the life of an item
Unlikely, but can reasonably be expected to occur
Improbable 1 So unlikely, it can be assumed occurrence may not be experienced
Unlikely to occur, but possible
To determine the consequence of failure, it is important to consider all of the possible costs of failure. These costs include: cost of repair; social cost associated with the loss of the asset; repair/replacement costs related to collateral damage caused by the failure; legal costs related to additional damage caused by the failure; environmental costs created by the failure; loss of business revenue to the community; and any other associated costs or asset losses. The consequence of failure can be high if any one of these costs is significant or the accumulation of several costs occur with a failure. Below is an example of a ranking system for the consequence of failure.
Consequence of Failure Levels
Description Level
Catastrophic disruption
5 Massive system failure, severe health affect, persistent and extensive damage
Major disruption 4 Major effect, major loss of system capacity, major health effects, major costs, important LOS compromised
Moderate disruption
3 Moderate effect, moderate loss of system capacity, moderate health effects, moderate costs, important LOS still achieved
Minor disruption 2 Minor effect, minor loss of system capacity, minor health effects, minor costs
Insignificant disruption
1 Slight effect, slight loss of system capacity, slight health effects
8 July 2013
Assessing Criticality
Assessing criticality requires an examination of the probability of failure and the consequence of failure as discussed above. The assets that have the greatest probability of failure and the greatest consequences associated with the failure will be the assets that are the most critical. The table below is an example of assessing criticality.
An analysis of different assets will reveal which asset has the highest criticality factor and, therefore, which asset would require the most attention either for repair or replacement.
Assessing Criticality
Multiplied Consequence (Cost) of Failure
1 2 3 4 5
Probability of Failure
1 1 2 3 4 5
2 2 4 6 8 10
3 3 6 9 12 15
4 4 8 12 16 20
5 5 10 15 20 25
To use this table, estimate the probability of failure from 1 to 5, with 5 being very high probability of failure and 1 being a very low probability of failure. Then assess the consequence of failure from 1 to 5 in the same manner. Using the number for probability of failure, move across the row until the column associated with the number for consequence of failure is reached. Alternatively, move down the column for the consequence of failure until the row for probability of failure is reached. Locate the number that is in the box where the row and column intersect. That is the criticality number for the asset.
As an example in a water system:
Asset: Pine Street water main; constructed in 1950
Service History: One service repair in the past 15 years
Probability of failure: 3 – the water main is old, and will most likely need to be replaced in the next 10 years, but is still in reasonable condition
Consequence of failure: 2 – The water main services a now-abandoned industrial park. The city wants to maintain fire service, but presently serves no customers. The water main has easy access, so repair is relatively easy and timely.
Probability of failure * Consequence of failure = Criticality factor
3 * 2 = 6
Criticality Factor: 6 – A 6 would not be considered a critical rating. Typically, an asset falling in the criticality range of 1 to 8 will not be considered critical. An asset falling in the criticality range of 9 to 16 will be important, but not critical. An asset above 16 in the criticality range will be considered critical.

Redundancy
When determining the criticality factor of an asset, one more element is considered – that of redundancy. Redundancy can significantly reduce risk. If one part of a system fails and there is not another part for redundancy and/or backup to immediately take its place, then risk is increased. Lack of redundancy in any system is not good.
Redundancy refers to whether there are other assets that are able to provide the same service if failure occurs. Does the utility have any other asset, system, or approach that will completely fulfill the function of the critical asset if it fails? Does the utility have any other asset, system, or approach to partially fulfill the function of the critical asset if it fails? If an asset is determined to be critical, then redundancy is critical. Risk should be managed in any decision-making process. The utility should analyze and document acceptable risk tolerance for all critical assets.
Criticality Analysis Over Time
The condition of the asset will change over time as will the consequences related to failure. Therefore, it will be necessary to periodically review the criticality analysis and make adjustments to account for changes in the probability of failure and the consequence of failure. As with all the components of the Asset Management Plan, the criticality analysis is an on-going process.
Using the Asset Inventory Tab
The Asset Inventory Spreadsheet, which is part of the workbook, has cell inputs for Probability of Failure and Consequence of Failure and then calculates the Criticality Factor. Use the Asset Description Tab to determine the numerical rating for Probability and Consequence for each asset. The Asset Inventory Spreadsheet will then calculate a Criticality Factor. If the Criticality Factor is greater than 18, the number will be bolded and the cell will be highlighted in red. This indicates that the asset and its failure is significant and should be added to the Capital Improvement Project Plan Tab.
Revenue Structure The rate methodology is a tool to determine rates and charges that will provide sufficient revenues to cover operation, maintenance, replacement, capital improvement projects, and debt costs. A billable flow methodology will generate revenue through a commodity rate based on usage. A readiness to serve or fixed charge methodology will generate revenues through a fixed unit such as a residential equivalent unit or meter equivalent unit. A fixed and variable methodology is a combined methodology and will generate revenues for fixed expenses through a fixed unit and generate revenues for variable expenses through a commodity rate. The fixed unit generates a fixed revenue stream, which is used to recover those costs that are incurred regardless of flow, such as insurance and debt payments. The variable rate generates revenue based on flow, which is used to recover those costs incurred due to usage, such as chemicals and power.
The budget should consist of the actual budget line items as required by the State of Michigan Chart of Accounts and other accounting statutes, rules, regulations, and requirements applicable to municipal entities. Only those costs related to the water system should be listed in the water budget. Accurate budgeting will help track and control spending, ensure accountability, and improve the ability to anticipate expenses.
Once total expenses have been identified, rates and charges can be reviewed to determine which will provide sufficient revenues to cover expenses. If subsidies occur, then the users of the system are not paying for the true cost of service – someone else is making up the difference. While temporary subsidies are sometimes necessary to cover unexpected costs,
10 July 2013
continued use of subsidies will result in either significant rate increases in the future or a problematic deficit in the water budget.
Replacement
The rate methodology should also include a replacement breakdown. This breakdown will identify items owned by the utility. These operating pieces of equipment generally have a useful life of 20 years or less with values of more than $500, contain moving parts, and would include such things as vehicles, generators, pumps, meters, and computers. Replacement items will also appear in the asset inventory, but usually have a dedicated funding source due to their limited useful life and importance to the operation of the system. On an annual basis, replacement funds are set aside in a dedicated “Replacement Fund” and build up until needed. The purpose of the Replacement Fund is to set aside money on an annual basis for items that will need to be replaced during the normal course of operating the system. Once a particular item fails, money is drawn from the Replacement Fund to replace the item in question without disrupting the existing budget.
Using the Replacement Tab
A Replacement Tab is developed that lists operating assets that will be replaced within the next 20 years that will be funded out of system revenues. The Replacement Tab will contain assets identified as replacement items. For each item, a remaining useful life and replacement cost is identified. The replacement cost is the cost to replace the item at failure or replacement time. The replacement cost is divided by the remaining useful life to calculate an annual contribution to the Replacement Fund for each item. The annual total amount for replacement will then be included in the budget as a line item. These items will be funded out of system revenues, so they must be accounted for in the annual budget and in the rates and charges.
Capital Improvement Project Plan A long-term Capital Improvement Plan (CIP) should look at the utility’s needs for the future. Ideally, the planning period would be at least 20 years, with a minimum of 5 years. It is understood that the specific expenditures and needs of the utility in the latter years, say 15 to 20 years, are more speculative than the needs for the first 5 to 10 years, particularly the first 5 years. However, the inclusion of the needs for this longer time period will provide a better opportunity for the water system to plan for its capital needs. Capital improvement projects are projects that the utility has an extended period of time to plan for and are projects that usually cover high cost, non-recurring items.
There are several categories of capital improvements that must be considered. The categories are listed below.
• Capital Needs Related to Future/Upcoming Regulations
• Capital Needs Related to Major Asset Replacement
• Capital Needs Related to System Expansion
• Capital Needs Related to System Consolidation or Regionalization
• Capital Needs Related to Improved Technology
In order to fund any short or long-term project, the utility must first identify the desired project and its anticipated cost. Once costs have been identified, the utility can begin to set money aside to fund future projects. The Capital Improvement Fund is funded on an annual basis and the accumulated Capital Improvement Fund monies can be used to supplement bonding for the
11 July 2013
particular project, act as a down payment or cover the entire cost of the project as determined by the utility.
Funding for Capital Improvement Projects
The utility determines the estimated cost of each identified project and the intended date for project initiation. The clear identification of the project, its cost, and the intended timeframe provides the utility with a defensible presentation for setting aside and safeguarding funds for projects.
The following information is helpful when prioritizing and gaining support for a capital improvement project:
• Description of the project
• Brief statement regarding the need for the project
• Year project needed
• Is the year needed flexible or absolute
• Estimate of project cost
• How costs were estimated
• Funding source(s) considered/available for this type of project
• Changes in overall operations that may occur as a result of the project (include operator requirements, additional O&M costs, regulatory changes, any efficiencies that may be gained, etc.)
• Impact of the project on LOS
As stated previously, the CIP should cover a 20-year period. It should be updated each year so that it always shows 20 years of needs. If there are no needs in a particular year, the CIP can reflect this. Annual review of the project list may reveal that some projects can safely be pushed back for several years or may not be needed due to changing conditions. The projects are planned several years in advance, so conditions may have changed, eliminating or reducing the need for an identified project. Alternatively, some projects may now need to be addressed sooner than anticipated and the CIP will need to be adjusted accordingly.
Some of the expenses related to capital improvements may be funded out of the system’s revenues rather than solely outside sources. If system revenues are to be used either to offset costs or as a debt repayment stream, the budgets and rates must reflect the costs.
Using the Capital Improvement Project Tab
A Capital Improvement Project Tab lists those projects that are planned for in the next 20 years. The spreadsheet will identify the projects, the anticipated timeframe in which the project will occur, the anticipated cost of the project, and the annual contribution to the Capital Improvement Fund for the item. The annual total amount for Capital Improvement Fund will then be included in the budget as a line item. These items will be funded out of system revenues, so they must be accounted for in the annual budget and in the rates.

Conclusion
Asset management is a systematic process of operating, maintaining, and upgrading assets cost-effectively. It is an active, on-going process that provides information to managers in order to make sound decisions about their capital assets and allows decision makers to better identify and manage needed investments in their utility’s infrastructure.
As the concept of asset management has grown in recent years, an extensive body of resources is now available to help develop and expand our knowledge and practice of asset management. This includes resources for utilities, such as software and guidebooks, as well as resources to help local officials understand and support asset management efforts. Asset management has been a major focus of the Environmental Protection Agency (EPA). The EPA has a dedicated website to asset management with numerous guidebooks for communities, which also offers on-line training and regional seminars on the subject. In addition, the EPA has also developed asset management software called Check Up Program for Small Systems (CUPSS), which is targeted for small communities. Furthermore, the DEQ has developed the asset management workbook described in this guide which is one of many tools a community can use for asset management.
Drinking water rules now require a detailed inventory of assets and capital improvement plans for publicly-owned water systems beginning in 2016. With more and more focus on asset management, it is important for your community to begin asset management planning and seek out the resources that will provide for current and long-term sustainability of your water systems.

Data Profiler Report – GIS Inventory
Summary Records per Table
Data ProfileThe following list contains the profiled database table names and their record count. The table name and record count are highlighted red if there are no records in a table. An asterisk (*) is placed in front of any table without a Primary Key and it is highlighted yellow.
The following pages detail each table having one or more records.Each table field is listed with the percent of populated, zero and negative values. An empty field has a Null value, zero length string or all spaces. Zero or negative values may occur in a numeric field. Although empty, zero and negative values are not necessarily invalid, they may indicate a problem. Fields containing all empty, zero or negative values are highlighted red. Fields containing 50-100% empty or zero values or any negative values are highlighted yellow.
Text fields may have the top 10 most occurring value lengths listed. If listed, the quantity of zero length strings will be highlighted red.The top 10 most occurring values (greater than 1% and occurring more than once) will be listed. Empty or zero values will be highlighted red.
An asterisk (*) is placed in front of any field containing all unique values, they are highlighted blue and **UNIQUE** is shown next to the field name.
