Technical Memorandum DATE: February 9, 2018 PROJECT: 17-5-094 TO: Gordon Stankowski, General Manager, Rural North Vacaville Water District CC: Justin Hopkins, PE, Senior Civil Engineer, Solano Irrigation District Matthew Medill, PE, Superintendent of Water & Power, Solano Irrigation District Sue Murphy, Water Quality Specialist, Solano Irrigation District FROM: Justin Shobe, PE, Senior Engineer, LSCE Aaron King, Project Engineer, LSCE SUBJECT: Board Summary: Vendor Proposals for Well 2 Arsenic Treatment

INTRODUCTION This memo provides a summary of the evaluation from the review of vendor proposals for the Well 2 arsenic treatment system. A Request for Proposals (RFP) was issued to arsenic vendors on November 2, 2017. Eight different treatment systems were proposed by vendors in response to the RFP. A meeting was held on January 16, 2018 among the recipients of this memo to review the proposals. At the meeting we narrowed the systems to two top-ranked vendors that LSCE then contacted for further information. A follow up meeting was to discuss the two top-ranked proposals. The purpose of this memo is to summarize the conclusions from the evaluation and the recommendations moving forward for vendor selection and system design.

VENDOR SELECTION In total eight arsenic treatment systems were proposed from six different vendors; four were adsorption systems and four were coagulation/filtration (C/F) systems. The proposed base system costs are shown below.

Table 1: Vendor System Costs Adsorption vs. C/F Systems Adsorption systems have significantly lower labor costs and operational complexity, while producing less waste requiring disposal, as compared with coagulation/filtration systems. Those positive characteristics are somewhat offset by the high cost of the adsorption media and its requirement for replacement every 1 to 3 years. The lowest capital-cost adsorption proposal (* on table at left), from AdEdge, was selected for implementation, although this was not the primary concern in the selection process.

Technology Base Cost Adsorption Vendor A $669,625 Adsorption Vendor B $180,000 Adsorption Vendor C $185,000 Adsorption Vendor D * $178,500 C/F Vendor A $929,000 C/F Vendor B $267,338 C/F Vendor C $220,000 C/F Vendor D $245,280

BOARD SUMMARY: ARSENIC VENDOR PROPOSALS FEBRUARY 9, 2018

LUHDORFF & SCALMANINI CONSULTING ENGINEERS 2

Proposals were evaluated based on the following criteria with input from RNVWD and SID.

1. Proposal Responsiveness to RFP and Overall Quality

2. Design Quality

3. Complexity and Ancillary Equipment

4. O&M Cost and Complexity

5. Performance Guarantee

6. Purchase Cost

Adsorption was chosen over coagulation/filtration due to the level of operational complexity associated with coagulation/filtration in terms of maintenance tasks (daily backwash cycles, backwash waste water storage, and sludge drying beds, and hazardous waste disposal). Coagulation/filtration also has a higher capital cost.

Among the 4 adsorption proposals, AdEdge (adsorption Vendor D in Table 1) was chosen for the following major reasons.

1. Local service personnel (locations in Sacramento and San Francisco),

2. Demonstrated a strong understanding of the specific water chemistry issues on Well #2 (high silicate), and provided realistic and conservative estimates of expected performance

3. AdEdge is the manufacturer of the adsorption media they use, unlike some of the other vendors that purchase the media from others. This translates to better understating of the media performance given the high silicate issues with Well #2.

4. Design and engineering quality, i.e. fully assembled, skid-mounted treatment vessels and valving, complete drawings and specs.

5. Competitive capital pricing and O/M costs.

NEXT STEPS Bench-scale standardized (Rapid Small-Scale Column Test) testing of the adsorption media with a representative sample of Well #2 water under normal operating conditions will be conducted to verify the estimate of media life (frequency of media exchanges). This will allow for more certainty in the ongoing costs of the system, which are driven primarily by the cost to replace the media. The cost of the test ($14,000) is a small fraction of the life-time cost of the system and would likely result in an improved performance guarantee in favor of RNVWD.

Preliminary designs will be developed with input from SID, RNVWD, and AdEdge, as well as the California State Water Resources Control Board Division of Drinking Water (DDW).

Permits and documentation of all certifications will be obtained and filed when DDW is satisfied that the designs meet all requirements.

Bid solicitation will commence when designs are finalized, and contractor(s) are selected to install the system.

Section 1: System Overview As detailed in this plan, the Rural North Vacaville Water District (RNVWD) and its staff will strive to provide a safe and reliable water supply for its customers. In the interests of public health and optimized domestic water system operation, RNVWD will adhere to the performance standards and operational goals as detailed in the California Safe Drinking Water Act and the California Water Works Standards, Title 22, California Code of Regulations, designed to maintain the operations and protect the quality of the water delivered to its users. RNVWD is a community water system serving an unincorporated area of rural Solano County, north of Vacaville, CA. The surrounding land is mixed agricultural and rural-residential comprised of the 22 square mile service area enveloping Cantelow Road, English Hills, Gibson Canyon, and Steiger Hill. The system is designed to provide drinking water for 533 metered service connections or approximately 1,508 people, by way of LAFCO’s Municipal Services Review Report 2.83 multiplier of people per households. The sources of supply are two (2) groundwater wells, Well 01, Primary Station (PS) Code 4810013-001 and Well 02, PS Code 4810013-002. RNVWD wells are located approximately 1000 feet apart, drilled to a depth of 1,400 feet (ft.), and producing as much as 350 gallons per minute (gpm). Well 02 continues to serve as an emergency standby source due to a history of arsenic contamination greater than 10 parts per billions (ppb), the maximum contaminant level. The wells are located in the Solano sub-basin of the Sacramento County Valley groundwater basin, DWR basin number 5-21.66. RNVWD chlorinates its water supply on a continuous basis. A supervisory control and data acquisition (SCADA) system monitors chlorine residual levels. The feed rate is controlled manually to provide delivered chlorine residual levels ranging between 0.5 and 0.8 mg/L. Using a double-walled containment for chemical storage, RNVWD stores 12.5% sodium hypochlorite with no dilution upwards of six (6) months before refill. The treatment facility is stored in a secure shed adjacent to Well 01. Each well is supplied chlorine by the centralized chlorine injection system supplied from a centralized treatment storage shed adjacent to Well 01. As a safety precaution, an eye wash station is located at each well site. The disinfection and oxidation chemical stored on site is 1087 Sodium Hypochlorite 9. The product is NSF/ANSI 60 certified per title 22 CCR §64590. The Prominent Control chlorine analyzer and chemical metering pumps inject chlorine through polyethylene black tubing downstream of Well 01’s check valve. The target residual fed to the well head is 1.5 mg/L free chlorine. RNVWD has two (2) storage tanks, one (1) surge tank, and one (1) hydropnuematic pressure tank. They are as follows:

Storage Facilities The RNVWD distribution system currently consists of 398 service connections across five (5) pressure zones. Water is delivered through approximately 40.3 miles of water mains ranging in size from four (4) inches to 12 inches in diameter, consisting of mostly Class 150 and 200 PVC piping. Security for the distribution system is adequate, as it includes chain linked fences, locked pump sheds, and storage tanks with locked ladders reducing risk of unauthorized entry, theft, or vandalism.

Tank 01 Station Site 3 300,000 gallons Coated Steel

Tank 02 Station Site 4 300,000 gallons Coated Steel

Pressure Tank Station Site 4 5,500 gallons Hydropnuematic Pressure Tank

The well pumps are operated by the tank level controllers and operate in series to supply the distribution system. Throughout the distribution system the pressure range varies between 60 and 130 psi due to terrain. The elevation in the system varies from 170 feet to 980 feet above sea level. Finished Water Pump Facilities Finished water pumping stations in the distribution system are adequate, with each facility having two (2) pumps. The pumps alternate, but can be activated to pump simultaneously to meet peak demands.

Table 2. RNVWD Pumps Facilities

RNVWD utilizes a SCADA system to continuously monitor and remotely operate the system as needed. This feature allows the system to set pressure parameters throughout the distribution system to alarm in case of malfunction requiring further investigation.

Pressure regulating valves are installed and maintained at each residential service connection to ensure an adequate delivery pressure range. Additionally, RNVWD contains four (4) pressure reducing valves located in Zone 2 supplying the greatest number of service connections along the English Hills service area. Cross Connection Control RNVWD is required by Title 17, Section 7584 of the California Code of Regulations (17 CCR §7584) to implement a cross-connection control program. RNVWD’s cross-connection control program includes: backflow protection devices at each service connection, personnel training, annual backflow prevention device testing, and records maintenance. RNVWD contracts with Trites Backflow Services to perform annual testing and cross connection surveys. The most recent cross connection survey was completed on August 1, 2016. Certified Operators In accordance with Title 22, Section 64413.3 of the California Code of Regulations (22 CCR §64413.3), RNVWD is classified as a D1 level distribution system. RNVWD meets the distribution system staff certification requirements of 22 CCR §64413.7 by contracting at least one (1) D1 designated chief operator, and at least one (1) D1 designated distribution operator whom are available to be contacted within one (1) hour.

Section 2: Routine Operational Practices

On a regular basis the RNVWD operations staff perform such duties listed below throughout the distribution system: Daily Operational Procedures

1. Monitor and record tank levels, well production, pumping plant flow rates, chlorine residuals and operating pressures.

2. Visually inspect for leaks, openings into the water system through spill pipes and air vents not being properly screened, lubricants, electrical hazards, chemical leaks, safety hazards and proper operation of pumps, wells and monitoring equipment.

3. Visually inspect tanks for leaks, corrosion, and deteriorated piping.

4. Visually inspect facilities for proper lighting and security throughout the perimeter of the facilities.

5. Visually inspect chlorine pumps, disinfectant reservoirs, disinfectant residual in all pressure zones of the distribution system, and disinfectant concentrations by using free chlorine test kits.

6. Inspect all gauges and meters for proper operation, leaks, and corrosion. Repair or replace apparatus as needed and keep records of the dates in which the corrections were made.

The RNVWD pressure is maintained by the existing water storage tanks and the booster stations. The operation of the well pumps and booster station 3 is controlled by a start and stop water level inside the water storage tanks. Booster stations 4 and 5 are controlled by specific pressure set points. If the distribution system pressure begins to drop below the specified set point, the booster stations are turned on in sequence to provide the required water delivery and maintain the pressure in the distribution system. In the event the system continues to lose pressure, an automated alarm system notifies operations staff of the problem. Staff will then respond to the alarming facility to verify the problem and take corrective action to maintain the pressure. The corrective action shall include appropriate flushing and disinfection with sampling to verify bacteriological quality and chlorine residual.

Reservoir Inspections and Cleaning In addition to RNVWD’s daily operational practices, biannual exterior reservoir inspections are conducted to determine the condition of:

Protective coatings and paint

- 6 -

Vents, overflows, drain pipe covers, and screening

Facility security, condition of access ladders, and tank entries

Condition of staff gauges

Floating surface water material

Interior inspections are conducted in accordance with AWWA Standard M42-2013 at least every five (5) years to determine the condition of:

Protective coatings and paint

Interior ladder

Overflows

Cathodic Protection

Support Columns

Floor to wall seems

And overall condition of the storage facility

Tank Disinfection Procedures Dry Entry: The disinfection and bacteriological testing of the tank prior to entering into service shall adhere to AWWA Standard C652-11. Water and chlorine are added to the storage facility in amounts such that the solution will initially contain 50mg/l available chlorine and will fill approximately five percent (5%) of the tank volume. The solution shall be held in the tank for a period of not less than six (6) hours. The tank will then be filled to the overflow level by flowing potable water into the tank. Once full, the solution shall be held for a period not less than 24 hours. When the tank level of chlorine residual has returned to 2 parts per million (ppm) the first bacteriological sample can be taken. After two (2) tests for coliform taken 24 hours apart are negative, the storage facility may be placed in service. If the test shows the presence of coliform bacteria, then repeat samples shall be taken until two (2) consecutive samples are negative or the facility must repeat the disinfection procedure. Diver Entry: Tanks that are cleaned by divers must first establish the chlorine residual and turbidity before entering the tank. Prior to entering the tank, all personnel and equipment are disinfected in accordance with AWWA Standard C652-11. After all personnel and equipment are removed from the tank, the chlorine residual in the tank should be re-tested. If the chlorine residual in the tank

- 7 -

did not drop during the inspection the facility can be returned to service as soon as a bacteriological sample is taken. If it was necessary to rebuild the chlorine residual the tank should not be returned to service until after completion of bacteriological analysis. Water Main Disinfection Procedures New Water Main Procedures: New water mains that are installed, whether expanding a distribution system or replacing a line, must be physically separated from the existing system until satisfactory flushing, pressure testing, disinfection, and bacteriological sampling has been completed. The new water main must be considered contaminated and the chlorine concentration used for disinfection makes the water non-potable. After satisfactory bacteriological sample results are obtained from the new water main, a section of connecting pipe must be installed between the new section and the existing system. Before installation, the interiors of all pipes and fittings used to make the connection must be swabbed or sprayed with an l% hypochlorite solution. Flushing and pressure testing the new water main must be completed and approved before beginning disinfection procedures. Upon completion and approval of the pressure test by the RNVWD project manager the M&I Operations Department will be notified. The disinfection and bacteriological testing of the new main shall adhere to AWWA Standards (AWWA C65l-14). The number of water samples taken will depend upon the length (one (1) sample for every 1,000 feet), and number of branches off the new main but a minimum of two (2) samples must be taken. These samples shall be taken from each end of the new water main. Two (2) consecutive samples at least 15 minutes apart must be reported and return negative bacteriological results. Results from bacteriological testing will be available the day after the sample is taken. Repairing existing mains: Leaks and breaks that are repaired while the mains remain full of pressurized water may present little danger of contamination and therefore do not require disinfection. When existing mains are wholly or partially dewatered, after the following procedures the existing main may be returned to service prior to the completion of bacteriological testing in order to minimize the time customers are without water. Slug chlorination is performed in the isolated section by applying chlorine continuously and for a sufficient period of time to develop a solid column, or slug, of chlorinated water that will, as it moves through the main, expose all interior surfaces to a concentration of approximately 100 mg/L for a least three (3) hours. If at any time the chlorine residual drops below 50 mg/L, the flow shall be stopped; chlorination equipment shall be relocated at the head of the slug and, as flow resumes, chlorine shall be applied to restore the free chlorine in the slug to not less than 100 mg/L. After the retention time, heavily chlorinated water should not remain in prolonged contact with the pipe. In disposing of heavily chlorinated water, a neutralizing chemical shall be applied to thoroughly neutralize the residual chlorine.

Distribution System Flushing/Dead-End Main Flushing RNVWD maintenance staff conduct routine systematic flushing of the RNVWD distribution system for the purpose of sediment removal and biofilm control. The frequency is typically biennial but may be modified based on water quality complaints, degradation, or drought. Flushing of dead-end mains is conducted annually but may be modified based on observed water quality. Records are maintained to document the date and location of all pressure and water quality complaints to help determine flushing locations and frequencies. The following procedures are followed during flushing activities:

Start at or near the water source working outward to not disturb sediments in portions of the system that have not yet been flushed

A minimum flushing velocity of 2.5 feet per second will be achieved

Distribution system pressure will not be allowed to drop below 20 psi during flushing activities

Flushing water energy will be diffused to prevent property damage and erosion

All water flushed will have its chlorine concentrations neutralized by dissolving sodium bisulfate tablets with in the diffuser

Flushing records will be maintained documenting the date, flow, flushing duration, discharge water quality and hydrant condition for a minimum of five (5) years

Inspecting and Exercising Water Main Valves To ensure that distribution system valves are accessible and operable at all times, the following water main valve exercising and inspection procedures take place biannually:

All valves are cycled from fully open to fully closed and then back to open. Caution is used when large valves in critical single-source transmission mains are cycled. Demand should be minimal and all valves should be cycled slowly to prevent potential water hammer impacts.

Inspection includes the examination of the condition of the valve box or vault and removal of any debris, if needed.

Records of all operation and maintenance are retained for a minimum of three (3) years.

- 9 -

Maintenance and Testing of Backflow Prevention Devices RNVWD staff are responsible for the protection of the water distribution system from contamination or pollution due to the backflow of contaminants or pollutants through water service connections. A State approved backflow assembly at each customer’s water service connection is required by RNVWD. The following procedures will take place:

All backflow assembly installations shall be approved by the RNVWD Cross-Connection Control Specialist

The type of backflow assembly required shall be a reduced pressure principle backflow preventer

All testing of system backflow assemblies shall be performed by an AWWA certified tester or Cross-Connection Control Specialist

All system backflow assemblies shall be tested annually

All system backflow assemblies shall be tested immediately after they are installed, relocated or repaired and placed into service

All testing records shall be retained for a minimum of 10 years
