1. PHASE I

1.1 Introduction

The Township of Essa has initiated a study, undertaken by AECOM Canada Ltd., to determine a preferred strategy for upgrades to the existing domestic water supply to address limitations related to the existing water works and to provide additional capacity for the existing Baxter settlement area and to accommodate future development. The study was originally completed under the Municipal Class Environmental Assessment (MCEA) process in 2004. Since that time the period of validity of 10 years for the Environmental Assessment has lapsed. This ESR will act as an update and allow additional opportunity for public input prior to proceeding with implementation.

1.2 Background

The Baxter settlement area includes a public elementary school and currently consists of 127 residential units with a population of approximately 450. The settlement pattern generally has residences fronting on Murphy Road and Denny Drive along with a subdivision fronting on Marshal Crescent. The existing Baxter Water Pumping Station presently services 53 residential units on Marshall Crescent and the elementary school. Domestic water supply for the remaining residences and business is by individual private wells. Sanitary servicing within the community is through individual private septic systems.

The existing pumping station was constructed in 1988 to provide a domestic water supply to the homes being constructed within the subdivision. It consists of a pre-engineered, brick structure located at Number 6 Marshall Crescent. This building houses process and disinfection equipment along with a standby diesel generator. The water supply consists of two drilled wells located east of the pumping station. Well No.1 is a 150 mm diameter, 85 meter deep drilled well equipped with a submersible well pump. Well No. 2 is also a 150 mm diameter well, 89 metres deep equipped with a submersible well pump. Well No. 2 is currently used as a standby well. There is no secondary pumping and the well pumps provide all flow and pressure to the water distribution system. Nominal water storage volume is provided by hydraulic tanks located within the pumping station to reduce well pump usage and cycling during periods of low flow. The existing communal wells are rated as per the Ministry Permit To Take Water at 255 cubic metres per day with one of the wells used as backup. The most recent Certificate of Approval, dated October 28, 2004, rates the treatment plant at a maximum capacity of 3.9 litres per second.

Potable water is discharged to the water distribution system through a 150 mm diameter watermain along Marshall Crescent and to the school. Fire hydrants are located along this watermain and are used only for flushing and watermain maintenance as the water supply system has insufficient capacity for firefighting purposes.

There have been historical complaints of water quality from some of the homeowners currently serviced by individual private wells. There is anecdotal evidence from the fact that the local store in Baxter sells a substantial amount of bottled water to the local residents.

Future expansion of the Baxter Settlement area currently includes vacant lands to the north of Murphy Road. Potential exists for an additional 250 units within the settlement area.

Township of Essa



Nearby communities include Angus, located approximately 8 kilometres north and Thornton, located 8 kilometres east. Angus has a current population of approximately 6,000 and Thornton has a population of approximately 1,000. Both of these communities have their own water supply and distribution systems.

1.3 Purpose of the Project

This Environmental Assessment was initiated to document the process to be followed to identify the preferred alternative solution to provide upgrades to the Baxter water supply and distribution system.

The Class Environmental Assessment was subsequent to investigations of the water quality and treatability studies of water from the existing wells. The Baxter area groundwater supply was identified as a result of testing to contain varying concentrations of ammonia levels. The presence of ammonia in the raw water results in the formation of chloramines when chlorine is added to the water for disinfection. Elevated pH and low free chlorine residuals are present even at high total chlorine concentrations. In addition, the ammonia concentrations are not consistent which makes treatment more difficult.

Consultations with representatives of the Ministry of Environment determined that to enhance water quality, the only feasible solution was removal of the ammonia from the water. This could be accomplished by either treatment or obtaining water from an alternate source. The final Certificate of Approval, dated October 26, 2004, contains requirements for upgrades for the removal of ammonia to prevent the formation of chloramines or to supply water from an alternative water supply which complies with the Ontario Drinking Water Quality Standards.

It should be noted that the water currently being supplied to the Baxter Community meets all Ontario Drinking Water Quality Standards and at no time has the water posed a health risk to consumers.

In addition to upgrades to service the existing residents the potential to service existing unconnected and future units should be examined.

1.4 Problem Identification

The problem identification for this Class Environmental Assessment is as follows:

Provide a source of drinking water for the Baxter Settlement area that meets current quality standards; and,

Upgrade the water supply system to accommodate existing and future development within the Baxter Settlement area.

1.5 Project Proponent

The proponent of this project is the Township of Essa.

Township of Essa



1.6 Project Location

The Settlement of Baxter is located east of the intersection of Simcoe County Roads 21 and 10, Lot 15, Concession 4, Township of Essa, County of Simcoe, and is shown on Figure 2.1.

2. CLASS ENVIRONMENTAL ASSESSMENT

2.1 General

The procedures to be followed in this Class Environmental Assessment are set out in the “Municipal Class Environmental Assessment” Document published by the Municipal Engineers Association, October 2000 as amended in 2007 and 2011. In accordance with that Document, the proposed undertaking corresponds to Project Schedule 2 of the Schedule “C” Water Projects: “Construct new water treatment plant or expand existing water treatment plant beyond existing rated capacity”. As such, the undertaking is considered to constitute a Schedule “C” project and the activity is subject to the full planning process of the Class EA. The planning process will therefore follow a phased approach as shown in the flow chart included in the MCEA Class EA Document. (See Appendix “A”). A minimum of three mandatory public contacts are required for Schedule “C” projects. A Notice of Study Commencement was issued on January 27, 2017. The notifications were by way of newspaper advertisements in the Alliston Weekender. Individual notices were also sent to review agencies. A copy of the Notice of Study Commencement as well as the list of review agencies is given in Appendix “B”. Following the original Notice of Study Commencement in 2004 no responses were received as a result of this initial notice.

2.2 Water Demands

2.2.1 Existing

Records for water demands for the years 2012 to 2016 have been compiled and presented in Appendix B. A summary of this data is given in the Table 2.1 below. The data presented in the Appendix represents total daily flows. Historical flow data was provided by the Ontario Clean Water Agency (OWCA) and is represented in tabular form below. The flow data for the year 2016 is current to December.

Township of Essa



The average day per capita flow is based on historical daily flows, 3.2 persons/lot for 53 lots or 170 persons. There is no data available for peak hour flows.

There is also a school in Baxter that is connected to the water system. Approximately 425 students attend the school of which 50 live in Baxter. Approximately 20 of the local students reside in the presently serviced area of Baxter and 30 of the students live in the unserviced area. At 30 L/c/d, an average daily flow of 12 m3/d is generated by the students who do not live in the presently serviced area. This means that the serviced residents of Baxter have an average daily water demand of 30 – 12 = 18 m3/d which equates to 106 L/c/d. This is well below the Provincial guideline of 450 L/c/d and the average daily water demand design flow of 212 L/c/d established in the 2006 report titled “Baxter Water Supply Improvements”. For design purposes moving forward the water demand design flow of 212 L/c/d will be adopted.

2.2.2 Existing Unconnected and Future Development

There are currently 75 existing residential units within the Baxter Settlement area that are currently serviced by individual private wells. In addition to the existing residential units, there is property presently designated for development that could support a draft plan of approximately 250 units. Any potential upgrades of the Baxter water supply and distribution system should take into account the opportunity for connection of these existing and future units. A summary table of existing and future demands is presented in Table 2.2

3. DESCRIPTION OF ALTERNATIVES

3.1 Introduction

Integral to the planning process is the adoption of alternatives to correct the noted deficiencies. The alternatives presented in this section are a broad range of potential solutions to address the problem of upgrading the water system for all lands within the study area. With the exception of Alternative 1 – Do Nothing, the alternatives will require the installation of servicing within designated servicing corridors, generally on public lands. In addition, there is potential for either upgrading the existing pumping station or construction of a new facility. Purchase of land for a new facility on a new site may be required.

3.2 Possible Alternatives

Reasonable alternatives for upgrades for the supply of potable water for the Baxter Settlement Area include the following: Alternative No. 1 – Do Nothing: Alternative No. 2 – Obtain water supply from the Collingwood Watermain: Alternative No. 3 – Obtain water supply from Angus: Alternative No. 4 – Obtain water supply from Thornton: Alternative No. 5 – Install new wells in the Baxter area: Alternative No. 6 – Treat water from existing Baxter wells: A summary of the above noted Alternatives are presented in the following paragraphs.

3.3 Alternative No. 1 – Do Nothing:

The Do Nothing alternative would leave the existing pumping station in operation and not expand the water system beyond the current serviced area.

3.4 Alternative No. 2 – Obtain water supply from the Collingwood Pipeline:

This alternative involves either upgrading the existing water pumping station to include storage and high lift pumping and connecting to the Collingwood Regional Pipeline as the source of water supply for the Community. The pipeline currently runs south along County Road 10 and a connection point was installed during construction of the pipeline at the intersection of County Road 21 for the possibility of a future connection to Baxter. Construction of a pumping station and reservoir could utilize the existing facility and property or another property could be purchased by the Township within the community. Due to the low pressure nature of the supply from the Collingwood Pipeline a location closer to the pipeline would be preferable.

Township of Essa



3.5 Alternative No. 3 – Obtain water supply from Angus:

A connection to the existing water system in the Community of Angus is an alternative that would require an 8000 metre long transmission watermain, a new reservoir and either upgrades to the existing pumping station or a new pumping station within Baxter. The reservoir and pumping station would be required to provide adequate storage pressure and fire flows due to the length of the transmission watermain from Angus. A transmission watermain from Angus could be constructed within existing right of ways. Depending on available capacity water would be supplied from existing and proposed new wells within Angus.

3.6 Alternative No. 4 – Obtain water supply from Thornton:

Implementation of this alternative is similar to obtaining municipal water from Angus. An 8500 metre long transmission watermain would be required in addition to new storage and pumping capacity located either in Thornton or Baxter. Water depending on demands and available water supply would be supplied from either existing or new wells in Thornton.

3.7 Alternative No. 5 – Install new wells in the Baxter area:

A local drilling program would be required to search for a new suitable source of water for the community. If a suitable water source was located then production wells would be required. In addition to new wells, the existing pumping station would have to be either upgraded or a new pumping station and reservoir would need to be constructed. Depending on the location of new wells, long watermains from the wells might be required to convey the water to the pumping station and reservoir. It is also likely that land acquisition would be required for new wells in the Baxter area.

3.8 Alternative No. 6 – Treat water from existing Baxter wells:

This alternative proposes installation of treatment equipment and processes to remove ammonia from the water from the existing wells or from new wells in the area. Treatment processes could include reverse osmosis or chemically enhanced filtration. In addition to treating the water most treatment processes produce reject water laden with the contaminants. A method and location for disposal of reject water would need to be established. This could involve several different processes including on-site dewatering to form a concentrate and then disposal of concentrate, or haulage of reject water to a sewage treatment plant.

In addition to treatment of the supply water, storage and upgrades to the existing pumping station or a new pumping station would be required to meet fire flow requirements.

4. PROJECT ENVIRONMENT

4.1 Introduction

This section provides a description of the physical, social and economic environment of the Baxter Settlement area. A combination of field investigation and review of existing engineering drawings was used to establish the inventory.

4.2 Physical Environment

1. Existing Vegetation

The proposed alternatives locate watermains within existing road right of ways. Locations for either a new pumping station and reservoir or new wells would require property outside of existing road right of ways. Within the existing road right of ways the existing vegetation is generally limited to grasses in the ditches and on the boulevards. Location of a new property for a pumping station is potentially identified as on either the north or south side of Murphy Road (County Road 21). Available property on the north and south sides of the road consists of farm fields. Existing trees are generally limited to hedgerows along property lines. Construction of a new facility could be located and designed to minimize impact to existing trees. Some vegetation will have to be removed for the proposed works. However, the impacts will be relatively minimal and will not remove rare vegetation or vegetation significant for wildlife habitat. 2. Sanitary System

There is no communal or municipal sanitary servicing within the study area. Existing sanitary servicing within the study area consists of individual private septic systems. Vacant lands and the existing park area are currently not serviced. 3. Storm Drainage

The study area is situated within the Nottawasaga River watershed. There are no storm sewers within the study area. Storm drainage generally discharges to the river through roadside ditches in developed areas, or by swales or overland flow within undeveloped areas. 4. Roads

Existing roads within the study area are constructed to a rural cross section with roadside ditches.

Township of Essa



5. Electrical Distribution System

The electrical distribution in the study area consists of overhead infrastructure along Murphy Drive (County Road 21) and underground infrastructure within the subdivision on Marshall Crescent. 6. Water Distribution System

Residents on Marshall Crescent and the Baxter Central Public School are currently serviced with by the communal water system. Depending on the outcome of this Environmental assessment, other areas within the settlement area may be serviced in the future. 7. Telephone System

Telephone service is provided in the area through underground infrastructure. 8. Gas Distribution System

Existing gas distribution piping is present along all roads within the developed area. 9. Photographs

Selected photographs within the study area are included in Appendix "D".

4.3 Social Environment

1. Heritage Resources

There are no heritage/cultural sites identified in the Baxter Settlement study area. 2. Parkland

There is a Township owned park within the study area. The park is currently clear of trees with a lit baseball diamond. Facilities within the park consist of a parking area and a covered pavilion.

4.4 Economic Environment

1. Economic Activities

Commercial activity in the Baxter Settlement area is limited to neighbourhood retail stores. There is no industrial base. Beyond the settled area the land is used for farming. The major intuitional use is the Baxter Central Public School with approximately 460 students. 2. Budget Considerations

Funding for the planning, design, and construction would come from the Township operating budget supplemented by provincial grants and/or development related contributions. This funding could be used to implement any of the alternative solutions presented within this study.

Township of Essa



Depending on the outcome of this environmental assessment, upgrades to an alternative will be budgeted in future years, or will be constructed in conjunction with future development within the settlement area. 3. Maintenance Costs

The pumping station on Marshall Crescent is currently in operation. Inspection and maintenance costs of water pumping stations are similar for most types of facilities and include regularly scheduled inspections and maintenance. 4. Construction Costs – General

The cost of the services would only be for residents who chose or are required to connect. The costs of a municipal pumping station and reservoir with backup power are estimated at $1,869,120. This construction cost estimate is for the facility only and does not include engineering, a source of water supply or any allowance for property acquisition. Lot owners would typically be required to pay a cost per lot plus the cost of a water service to property line. The supply and placement costs from the property line to the house, including any new internal pipe works, would be the lot owners’ responsibility. 5. Construction Cost of Alternatives

Alternative 1 – Do Nothing No Cost Alternative 2 – Obtain water supply from the Collingwood Pipeline Pumping Station Cost $1,969,120 Watermain Distribution System $17,500 Engineering and Contingency $319,000 TOTAL $2,305,620 Alternative 3 – Connect to Angus Water System Pumping Station Cost $1,969,120 Watermain Distribution System $35,000 Transmission Watermain $1,760,000 Engineering and Contingency $470,515 TOTAL $4,234,635 Alternative 4 – Connect to Thornton Water System Pumping Station Cost $1,969,120 Watermain Distribution System $35,000 Transmission Watermain $1,848,000 Engineering and Contingency $481,515 TOTAL $4,333,635 Alternative 5 – Install New Wells in Baxter Area Pumping Station Cost $1,969,120 New Wells and Watermains $1,054,000

Township of Essa



Watermain Distribution System $35,000 Engineering and Contingency $382,265 TOTAL $3,440,385 Alternative 6 – Treat Water From Existing Wells Pumping Station Cost $1,969,120 Treatment Works $819,000 Watermain Distribution System $35,000 Engineering and Contingency $339890 TOTAL $3,059,010 Refer to Appendix "C" for detailed breakdowns of costs for each alternative.

4.5 Design Considerations

Design considerations for an alternative include minimizing the environmental impact of any construction activities, keeping costs per unit of the project to a minimum, and minimizing long term maintenance costs. The selected alternative will need to provide capacity to service the existing population with both domestic and fire flows and have capacity for future expansion. The current pumping station is a single stage, direct pumping system with no water storage other than hydraulic pressure tanks. Since there is no storage and the wells have a limited capacity, fire flow is not provided by the system. Alternatives included above provide for a new pumping station and reservoirs to house upgraded equipment necessary to provide fire flows and standby power. In addition either above or below grade reservoirs are required. Construction of two reservoirs is recommended to allow one reservoir to remain in service while the other is removed from service for cleaning or maintenance work.

Maintenance costs of a facility with an enhanced treatment option could be substantially higher than the existing costs due to process, operational or water quality testing requirements. This can be a factor when considering life cycle costs of an alternative.

Preliminary engineering design for the various alternatives indicates that water supply infrastructure within the study area can be accommodated using minimum Township of Essa Design Standards. Looping of branches of new watermains is advisable to help create circulation within the system and prevent water from stagnating in dead end watermains.

5. SCREENING OF ALTERNATIVES

5.1 Introduction

The alternatives developed in Section 3 to address the problem statement in Section 2 are to be screened with respect to their impact on the physical, social and economic environments presented in Section 4. The potential environmental effects of the alternatives are listed in the respective Tables 1 to 6 at the end of this section:

5.2 Alternative No. 1 – Do Nothing:

Action Required: None. Advantages No additional construction required. Disadvantages Does not address the problem statement.

The Do Nothing alternative is not viable since upgrades to the existing water supply system are required under the current Certificate of Approval from the Ontario Ministry of the Environment.

5.3 Alternative No. 2 – Obtain water supply from the Collingwood Pipeline:

Action Required: Connect to Collingwood to Alliston Pipeline. Upgraded pumping station and storage reservoir. Advantages Water supply is an existing and proven source. Potential for expansion of supply. Supply is close to the Community, minimizing connection length. Disadvantages Supply of water is fixed, based on contractual quantity.

Construction of this alternative would involve a connection to the existing Collingwood Regional Pipeline at the intersection of County Roads 10 and 21. A connection is relatively straightforward since a connection point was established during original construction of the pipeline. Crossing of the intersection could be coordinated with a proposed future reconstruction of the intersection by the County of Simcoe. The Collingwood Regional Pipeline which became operational in May of 2000 is presently supplying treated water to the Town of New Tecumseth at a nominal rate of 9500 m3/d. At the present time, this figure is a minimum daily quantity. The initial capacity limit of the Regional Pipeline is 23,500 m3/d. The pipeline is designed as a low pressure, high volume transmission main which provides a relatively constant supply of water to municipal

Township of Essa



customers. Use of water from this pipeline requires a storage reservoir to provide a buffer for peak demands, emergency and fire flows, and a pumping station to pump from the reservoir to a distribution network.

Construction of a pumping station and reservoir could utilize the existing facility and property or another piece of vacant property could be purchased by the Township along Murphy Road. Due to the low pressure nature of the supply from the Collingwood Pipeline a location closer to the pipeline would be preferable.

The proximity of this proven source of water to the settlement area would minimize the length of watermain required for connection to this supply. Watermains could be run within existing road right of ways with the exception if a new property is used for construction of a new pumping station and reservoir. Water from the pipeline is purchased under contract for a set daily amount. Charges for the full daily volume of water are applied regardless if the contracted amount of water is used or not. If additional water supply is required, it would require amending the supply contract with New Tecumseth. Future expansion of supply from the watermain will depend on the amount of remaining capacity. The capacity in the pipeline is allocated on a first come basis. At the present time there is surplus capacity allocated for future expansion of the water supply system in the Baxter Settlement Area.

A significant advantage is that water from the pipeline is treated, approved and the source will not diminish in capacity since the water is obtained from Georgian Bay. Payment for the water includes all supply and treatment costs. It also removes the responsibility for supply and treatment from the Township of Essa

5.4 Alternative No. 3 – Obtain water supply from Angus:

Action Required: Connect to Angus water system with a 8,000m long watermain. Upgrade Baxter pumping station and storage reservoir. Advantages Water supply is an existing and proven source. Disadvantages Supply is far away, high capital cost for watermain. Limited supply in Angus. Does not provide for future expansion within Baxter.

A connection to the existing water system in the Community of Angus is an alternative that would require a transmission watermain and a reservoir and pumping station within Baxter. The reservoir and pumping station would be required to provide adequate pressure and fire flows due to the length of the transmission watermain from Angus.

A transmission watermain could be constructed within existing right of ways, thereby minimizing environmental impacts. The cost of a transmission watermain from Angus to Baxter would be expensive due to the length, reducing the feasibility of this alternative.

The use of existing wells in Angus as a source is not a viable alternative at this time since there is an identified shortfall in capacity for future growth in Angus. Using the Angus system to supply water to Baxter would compound the shortfall.

Township of Essa



5.5 Alternative No. 4 – Obtain water supply from Thornton:

Action Required: Connect to Angus water system with a 8,500m long watermain Upgrade Baxter pumping station and storage reservoir Advantages Water supply is an existing and proven source Disadvantages Supply is far away, high capital cost for watermain Limited proven supply in Thornton Does not provide for future expansion within Baxter

Implementation of this alternative is similar to obtaining municipal water from Angus. A transmission watermain would be required in addition to additional storage and pumping capacity located either in Thornton or Baxter.

5.6 Alternative No. 5 – Install new wells in the Baxter area:

Action Required: Undertake a drilling program to search for new sources of water Install municipal well and connect to Pumping Station with watermains Upgrade Baxter pumping station and storage reservoir Advantages Potentially a local source of water Disadvantages Unproven source, no existing suitable nearby wells May require property acquisition Drilling program is expensive and costs are not recoverable if a suitable source is not found.

A local drilling program would be required to search for a new suitable source of water for the community. A review of the area by a Hydrogeologist suggests that it is unlikely that an acceptable new source of water will be found in the vicinity of the community. A drilling program to verify the presence of an acceptable aquifer would cost approximately $150,000 with no guarantee of success.

If a suitable water source was located then production well would be required. In addition to new wells, the existing pumping station would have to be either upgraded or a new pumping station and reservoir would need to be constructed. Depending on the location of new wells, long watermains from the wells might be required to convey the water to the pumping station and reservoir. It is also likely that land acquisition would be required for new wells in the Baxter area.

5.7 Alternative No. 6 – Treat water from existing Baxter wells:

Action Required: Upgrade treatment at the Baxter Pumping Station; Upgrade Baxter pumping station and storage reservoir; Advantages Uses water from existing wells; Disadvantages

Township of Essa



Most treatment technologies create reject/backwash water and there is no place to discharge this water in the Baxter area;

Treatment equipment and operation is expensive; Requires haulage or dewatering of reject water.

This alternative proposes installation of treatment equipment and processes to remove ammonia from the water from the existing wells or from new wells in the area. The most significant problem with this alternative is that all processes for treatment of water, such as reverse osmosis or chemically enhanced filtration, produce reject water. There is no nearby sewage treatment plant or body of water where the reject water can be discharged. As a result the reject water from the treatment process would have to be hauled to a sewage treatment plant or concentrated on site and the concentrate then disposed. In addition to the issues of disposal of reject water, the long term costs of operation of this type of facility is more expensive due to future replacement of treatment equipment and ongoing operational costs.

5.8 Potential Mitigative Measures

1. Disruption to Trees and Vegetation

If a new location for a pumping station is required during the detailed design stage of the project, either a site with limited tree cover or the location of structures to minimize the impact on existing trees would be used. New watermains or transmission watermains would be run within existing road rights-of-way, which generally have few trees. If significant trees are encountered, then directional drilling could be used to avoid cutting established root systems. 2. Visibility of Pumping Station

Construction of a new pumping station and reservoir, either on the existing site or in a new location, would take into account neighbouring architecture. Architectural and landscaping details can be used to minimize the ocular impact of above grade structures.

3. Noise and Dust

All construction activities will temporarily generate noise and dust. The effect of dust can be minimized during construction by spreading calcium chloride and water on exposed dry granular bases. Construction activities would generally be limited to normal weekday working hours minimizing the impact of noise on residents. 4. Disruption of Utilities

All stakes-outs are to be arranged and hand digging techniques are to be employed when constructing services over or under existing utilities to minimize the potential disruption of utilities during construction. Construction may require utility relocations.

6. PUBLIC CONSULTATION

6.1 Introduction

A Public Open House was originally held in 2004 in accordance with requirements for a Schedule C Class Environmental Assessment. An Information Bulletin consisting of an executive summary of the Class EA document, a Comment Sheet, was distributed to attendees of the Open House. No Part II orders were received during the original EA process. As the original EA validity period of 10 years has expired, a Notice of Study Commencement was issued and the ESR was made available for public review for 30 days to invite additional comments and public engagement. A Copy of the Notice of Study Commencement is included in Appendix B for Reference.

6.2 Results of Original Public Consultation

In general, comments from the public were very supportive for the prospect of a new source of water for the community of Baxter. In addition to discussions from the Public Open House, one member of Council for the Township of Essa lives in Baxter and also owns the general store in the community. Because of this he was able to discuss the various options and get feedback from many member of the community that did not attend the Open House.

6.3 Major Areas of Concern

No Comment Sheet responses from the original Public Open House in 2004 were received. The major area of concern that was voiced by participants at the Open House is the cost to individual residents of providing upgraded water service. In addition, the quality of water was a concern since many residents are not satisfied with the taste of the water from both the municipal system and from private wells.

6.3.1 Costs of Services

The issue of cost was of prime concern to respondents with most of the respondents making a comment on project costs and the impact of these costs to the benefiting properties. Concerns were relayed that certain individuals were on fixed incomes already, and could not afford any additional costs. Water servicing for lots not currently connected, will be the individual homeowner’s responsibility to pay a fixed frontage cost, as well as a connection fee (nominal). To assist those on fixed incomes, Township staff will recommend to Council that the Township provide financing so that the costs for servicing can be spread over a longer period. Also, the Owner must pay for the connection from the property line into the house on private lands and plumbing costs within the house (cost varies between owners).

Township of Essa



Although there will be a cost to some individual homeowners at the outset, these costs will be offset by an elimination/reduction of future expenses related to operation and maintenance of individual water systems.

6.3.2 Environmental Concerns

Environmental issues were not a major concern with the participants at the Open House or respondents. The proposed locations for a new pumping station were generally in open areas so there would be limited to no effect on existing trees or sensitive vegetation. Construction activities would only have temporary effects with the majority of the construction activities located within road right of ways.

It is important to note also that the negative environmental effects of not dealing with substandard water quality in the community are far greater than that of any effects of temporary disruption while under construction.

6.3.3 Location of the Pump Station

There were several verbal questions regarding the location of the Pump Station. The Pumping Station location is proposed to be located either on the existing site or on the north or south side of Murphy Road (County Road 21). A new building is proposed to be aesthetically designed to blend into the existing neighbourhood or surrounding lands. The exact local of the Pump Station will be determined at the detailed design stage.

There were no objections for location of a new pumping station in either the existing location or along Murphy Road.

Township of Essa



7. SELECTION OF PREFERRED ALTERNATIVE

The selection of a preferred alternative for Phase II of the Class EA is based on the evaluation of the alternatives from criteria established for this document. The criteria for evaluating each alternative are presented in Table 7. The evaluation criteria are ranked based on their relative importance, and scored according to the individual effect to determine the net effect of each criterion. The total environmental effect is the sum of the net effects for each alternative.

Alternative 2 – Obtain Water Supply from the Collingwood Pipeline, was selected as a preferred alternative for the following reasons:

Addressed the problem statement; Evaluated with the highest score; Highest scores for impacts on the physical and social effects; and Overall lowest economic impact.

Township of Essa



8. ALTERNATE DESIGN CONCEPTS FOR THE PREFERRED SOLUTION

8.1 General

Several potential design concepts exist for the preferred solution of obtaining a new water supply from the Collingwood Water Pipeline. In general, the components required of any alternative include: A connection to the pipeline at the intersection of County Road 10 and Murphy Drive (County Road 10) Transmission watermain from the pipeline connection to a pumping station. Upgrades to the existing pumping station or a new pumping station including high lift pumping, electrical

controllers for the new pumps and a standby generator. Provision of above or below grade water storage.

The proposed water system for the Baxter settlement area will be constructed in phases to first service existing development and then service existing residents and finally to provide capacity for future expansion within the settlement area. Alternative designs for a municipal water system are limited by both Municipal and Provincial regulations and standards. Municipal design standards and MOE design criteria dictate level of service such as design flows, and minimum pressures. Municipal design criteria also require various levels of fire protection depending on the number of residences connected to the system.

To ensure sufficient capacity to directly provide fire flows, a storage reservoir is required. A storage reservoir is also required since supply from the Collingwood Pipeline is delivered over a 24 hour period. There is no guarantee of the rate of water supply from the pipeline only that the contracted amount is supplied every 24 hours. Since the pipeline cannot be relied upon to supply any demands storage is required for equalization.

8.2 Design Alternatives

The above mentioned components will be required to work as one unit to provide a functional water system. Several components, such as the connection to the pipeline and transmission watermain from the pipeline to the pumping station, are dependent on the location of the pumping station. Therefore, the primary decision is if a new pumping station is required and then the location of the pumping station can be assessed. In conjunction with a pumping station, the construction of reservoirs must be considered. Reservoirs for the pumping station can be constructed either above or below grade. The selection will depend on many factors such as ground conditions, and groundwater table, physical space available and aesthetics of the site. Because of the variables, the selection of the reservoir type will be determined at the detailed design stage of the project.

Possible design alternatives for the Pumping Station include the following:

1. Utilize existing pumping station with upgrades 2. New pumping station at existing site 3. New pumping station at a new location

Township of Essa



A summary and discussion of the above noted Design Alternatives is presented in the following sections.

8.3 Design Alternative 1 – Utilize existing pumping station with upgrades

This design would use the existing pumping station as a starting point for construction of an upgraded facility. Because of the relatively small size of the facility, an expansion would be required to house the additional required equipment. Difficulties arising with this alternative would be to maintain operation of the existing station and water system while construction proceeds within the same building. Effectively the project would result in a new, larger building. Construction of either above or below grade reservoirs would also be very difficult as the location would be constrained by both the location of the existing wells and the existing pumping station. Overall this would lead to a less than optimal location for the reservoirs. Construction of a larger building if combined with above grade reservoirs would have an aesthetic impact on the neighbourhood due to size and height of the standpipes. The transmission watermain from the Collingwood Pipeline to the pumping station would be a much greater distance when compared to possible locations for a new pumping station. This is a distinct disadvantage over a facility located closer to the pipeline since the pipeline operates as a relatively low pressure, high volume watermain. The longer distance would require a larger diameter pipe to meet the same flow rates. A longer and larger diameter transmission watermain would also contain a greater water volume, leading the possibility of water sitting in the transmission main for more than one day during low demand periods of the year.

8.4 Design Alternative 2 – New pumping station at existing site

A new pumping station located within the same site would be subject to similar constraints as expanding the existing pumping station. Construction works would be simpler as the existing station could remain in operation undisturbed while construction of a new station proceeds. Below grade storage could be utilized and form part of a foundation for the above grade structure. However, space constraints within the existing site are similar to Design Alternative 1, limiting site location to an even smaller unused area within the existing property. In this case, a pumping station and reservoirs would have to be located to avoid the existing wells in addition to the existing structure.

Comments from Design Alternative 1 regarding the length and diameter of a transmission watermain from the Collingwood Pipeline to the pumping station remain valid for this alternative.

8.5 Design Alternative 3– New pumping station at a new site

Planning Alternatives previously identified in Section 4 proposed a new location for a new pumping station and reservoirs. There is presently vacant land on both the north and south sides of Murphy Road (County Road 21), between County Road 10 to just west of the existing urbanized area of Baxter. A new pumping station could be

Township of Essa



located within this area. Advantages of a new site in this area would include the flexibility to locate and design a new pumping station and reservoirs without constraints that would occur on the existing site and the pumping station would be much closer to the Collingwood Pipeline, minimizing the size and length of transmission watermain that would be required.

Construction on a new site would also prevent interference with the existing pumping station and water supply system. The existing system could simply be shut down and abandoned with the new system supplying water to the community. After abandonment of the existing system, the property could be used for other functions, such as a park or the Township could sell the property to recover some costs.

8.6 Phasing of Construction

Upgrades or construction of a water system for the community could be done in phases. The first phase of construction would service existing water users within the community which was completed in 2007. The second and third phases would service currently unserviced properties and future development respectively.

Since fire flow is desired from the system, the water demand from fire flows is greater than either Maximum Day Demands or Peak Hour Demands for the third phase. Pumps can be installed with variable frequency drives to supply water for all phases up to the ultimate design yet have the capability of economically running the system at low flow rates.

The major change between phases would be the required reservoir storage capacity. Total storage capacity varies from a requirement of 404 cubic metres for Phase 1 to 750 cubic metres for Phase 3. Initial storage can be constructed to accommodate requirements for either Phase 1 or 2 and designed for expansion to service future Phase 3 development. Both above and below grade tanks can be designed to be expandable.

8.7 Evaluation of Potential Environmental Impacts

The environmental impacts of the design concepts generally differ due to location of the new pumping station and reservoir. Each alternative would utilize the same source of water, require a transmission main from the pipeline to the pumphouse and connect to the existing water distribution system in the community. The impacts of the three alternative designs for water storage reservoirs are provided in Table 8.1, 8.2 and 8.3 respectively.

8.8 Selection of Preferred Design

Based on the evaluation of the alternatives, the design concept with a new pumping station and reservoir on a new site is selected as the preferred design. The primary reasons for this selection include:

Minimum capital cost estimate, Flexibility for design and construction of the new facility while maintaining operation of the existing water

system, A new property can be purchased that is larger than the existing property to provide a larger area for

construction and mitigation. Aesthetic impact that can be mitigated through building height control and plantings,

Township of Essa



9. SELECTED DESIGN AND CONSTRUCTION REQUIREMENTS

9.1 Selected Design

The selected design will utilize the transmission watermain to discharge to the proposed reservoir. As previously noted the reservoir can be either above or below grade. High lift supply pumps will provide domestic and fire flows to service residents currently connected to the existing water system, and expansions of the Baxter water system to service unconnected properties and future development.

The proposed pumping station site should have a minimum area of approximately 45 metres by 45 metres. This provides adequate room for construction of the pumphouse and reservoir. The size of the site will provide adequate setbacks from existing road allowances and adjacent or future residences and septic systems.

The reservoirs can consist of above ground, pre-manufactured steel tanks or underground concrete tanks. The tanks would generally be located behind the pumphouse, or towards the rear of the site in the case of above ground tanks. The ultimate volume required for the tanks would be 750 cubic metres plus an additional emergency volume required if the Collingwood Pipeline is out of service. The reservoirs can be designed to be constructed to a volume to suit requirements of each phase of the water system and expanded as required.

High lift pumping would consist of multiple variable speed pumps to provide flows ranging from minimum demands to Maximum Day Flow plus Fire Flow. The pumps would be configured to provide redundancy to meet the maximum demands with the largest pump out of service.

Periods of low residential demand would be accommodated by controlling one of the duty pumps with a variable frequency drive controller. The controller allows the pump to run at varying speeds to match water demands

9.2 Projected Water Flow Demand

The following Table 9.14 is summarized from Table 2.2 and provides the design criteria that must be met for each phase of expansion of the proposed water system.

Peak Hour Demand 3.4 10.3 26.1

Fire Flow 38.0 38.0 43.7

Fire Flow + Max Day Demand 40.3 44.9 61.1

9.3 Water Supply from Collingwood Pipeline

The Collingwood Pipeline is designed to supply treated water to a reservoir over a period of 24 hours. Consequently sufficient reservoir capacity is needed to meet equalization, fire and emergency storage requirements in addition to providing sufficient volume to meet demands if the Collingwood Pipeline is out of service for 1 to 2 days. The recommended storage volume would provide approximately 2 days of water at Maximum Day Demand rates. If the Pipeline did shut down for an extended period then water conserving measures would be enforced in the community to maintain reserves in the reservoirs.

Some of this additional capacity would also be used on a day to day basis since the supply of water from the pipeline does not match daily demand variations. Minimum storage requirements assume that the supply rate equals the Maximum Day Demand flow rate. Since this is not the case, additional storage will be required. The actual amount of additional storage will be determined at the detailed design stage when operating characteristics and a supply contract is entered into for supply of water from the Pipeline. The following table presents water supply requirements from the Collingwood Pipeline and minimum and recommended reservoir storage volumes.

Minimum Storage Required 404 527 750

Recommended Storage (2 days) 404 1,186 2,670

Township of Essa



9.4 Use of Surplus Purchased Water in Angus

As previously noted, the contracted daily supply amount from the Collingwood Pipeline is paid for if it is required or not. It is expected that during the winter the demands will be approximately one third of the Maximum Day Demand. It is proposed that surplus water is diverted from Baxter to the Angus water system through a connection to the Collingwood Pipeline adjacent to the Mill Street Reservoir. This connection was previously addressed in an Addendum to the Angus Water Supply System Environmental Assessment, completed in 2004. As upgrades to the Angus water supply system have since been implemented this option is not likely required however remains an option for future consideration.

9.5 Distribution System

The initial phase of construction will connect the proposed pumping station to the existing water distribution system. Future phases will expand the existing water distribution system.

The water distribution system will generally consist of 150 mm diameter watermain, hydrants and valves installed within the road right of ways to Township standards. A looped configuration will be used to maintain flow and movement of water within the watermains. Service connections will be provided to the property lines of each lot. Watermains within future developments will be installed by the developer in conjunction with servicing of the subdivision.

The Township constructed the watermain to service the 53 existing residents in 2007. Hydrants were not installed as capacity for fire flows was not available, and services were terminated at the property line for residences along County Road 21. Costs for individual properties are based on the total cost of the watermain divided by the total number of properties that are serviced by that watermain.

9.6 Potential Impacts and Mitigating Measures

Previous sections of the report have identified potential environmental impacts associated with the selected design. This section addresses each of these impacts in list format and outlines the mitigating measures proposed to minimize the impacts.

Impact: Visual impact of new works

Landscaping of the grounds surrounding the reservoir and pumphouse. Limiting height of and above grade reservoir to approximately the height of residential houses or using a below

grade reservoir Architecturally acceptable building construction specified compatible with surrounding residential uses. Impact: Increase in noise/vibration levels

Specify adequate wall and roof insulation in the pumphouse construction; Provide anti-vibration mountings for certain pieces of equipment, e.g., diesel generator; Provide a vegetative buffer around the pumphouse; Maximize the distance between the pumphouse and the nearest building.

Township of Essa



Impact: Safety

Provide locked doors and covers to all building windows, chambers etc.; Provide an alarm system to warn of specific emergency condition that may arise.

Impact: Reliability of the water supply system

Provide backup power in the form of a generator; Provide backup units for major components e.g. pumps; Provide extra reservoir capacity to account for times when the Collingwood Pipeline may be out of service.

Impact: Disruption during construction

Locate the pumphouse away from existing residential properties. Confine construction activities to a localized

area.

9.7 Estimated Costs

The second phase of development which is currently required would include the expansion of the reservoirs and extension of the water distribution system. The estimated cost of the upgrades and watermain distribution system is $2,305,620.00.

Costs for extending the water system to future development could be paid through Development Charges. A summary of costs per phase is presented in Table 9.3 below.

Operational costs would be covered through water charges based on a metered rate. The metered rate will vary with the total number of customers connected to the system since full cost recovery for water systems has been mandated by the Province. Incremental costs of additional usage are minimal, consisting of electricity for pumping and chemicals for disinfection and treatment. The costs of inspection and water quality testing represent a large

Township of Essa



component of the total operational costs of a small system, estimated at $20,000 to $30,000 per year. The cost of water from the Collingwood Pipeline for 200 cubic metres per day would total approximately $23,000 in 2004 dollars. The water cost is fixed based on the contracted daily supply amount whether the water is used or not.

Township of Essa



10. SUMMARY

The proposed new communal water system for the Community of Baxter will provide a source of potable water for existing and future residents. The new system will use water from the Collingwood Pipeline, supplying treated water from Georgian Bay. Phasing of the system will provide the infrastructure necessary to expand the existing water system to existing unserviced properties within the community. The new water system will also offer positive benefits for future development within designated lands Operating costs for the homeowners of a municipal system will be in part offset by lower fire insurance premiums when fire protection is provided by the system. There are considered to be no major negative impacts resulting from the design, construction and operation of the proposed works. Negative impacts that have been identified can be readily accommodated in the final design. Positive impacts include the establishment of a water system that will provide a reliable and safe domestic supply, along with fire protection, to the Baxter Community. Based on the findings of the Environmental Study, the recommendation is to proceed with design on the basis of a new municipal water supply system to meet obligations under the current Certificate of Approval issued by the Ministry of Environment.

Notice of Commencement

PUBLIC NOTICE

CLASS ENVIRONMENTAL ASSESSMENT

TOWNSHIP OF ESSA (BAXTER SETTLEMENT AREA) WATER SUPPLY AND DISTRIBUTION SYSTEM UPGRADE

NOTICE OF STUDY COMMENCEMENT

The Township of Essa previously initiated a study to analyze various alternatives for upgrading the existing water supply facilities serving the Baxter Settlement Area in 2004. Due to the period of validity of the original Class Environmental Assessment expiring after 10 years, the study is now required to be updated and the public notified throughout the process. The purpose of the expansion would be to address limitations related to the existing water works and to provide additional capacity for the settlement area. Options may include locating a new water source, upgrading or decommissioning the existing water plant, and/or the construction of a new water pumping station and storage reservoir. This project is being planned under Schedule ‘C’ of the Class Environmental Assessment for Municipal Water and Wastewater Projects. Comments and input from the Public on the above noted proposed works are invited for incorporation into the selection of the preferred solution and will be received until February 24th, 2017. Further notices will be forthcoming by published announcement. Subject to the comments received and the receipt of other approvals as necessary, the Township of Essa intends to proceed with the planning, design, and construction of the project, to be completed by Summer 2018.
