Preliminary Map, Plan, and Report Town of Batavia Pratt Road Water District -1- October 2012

I. General The Town of Batavia has received interest in establishing a water district. A water district is a special use district required by Town Law where a specific area of the town receives a specific benefit. The cost for receiving this benefit will be borne solely by those property owners in that specific area. The purpose of this project is to provide safe and reliable potable water supply and fire protec-tion to residences in the proposed Town of Batavia Pratt Road Water District. II. Project Planning Area

A. Location

The project area has been identified through public interest. The Town of Batavia Pratt Road Water District will connect to an existing Town of Batavia water district and in-clude approximately 16,000 linear feet of 8-inch diameter water main. The water main will be installed along Pratt and Powers Roads and serve approximately 32 units and is shown as the solid red line noted on Figure 1 at the end of this report.

B. Environmental Resources Present

There are farmlands present in the project area. All construction will be taking place in existing road-right of ways and proper construction mitigation and restoration efforts will be implemented based on standard practices common to the industry.

C. Growth Areas and Population Trends

The project area is primarily residential and agricultural. The total census population of the Town of Batavia in 1990 was 6,055. Between 1990 and 2000 the Town’s population decreased by 143 to 5,912.

III. Existing Facilities

A. Location Map

The proposed facilities are shown in Figure 1.

B. History

The entire area of the proposed water district is presently served by private wells.


C. Condition of Facilities

The Town of Batavia has received several complaints about the quality, and at times, quantity of the private water supplies in the area. From public input it is known that many wells in this area are contaminated with high levels of sulfur, iron, and coliform and high hardness level. Many of these wells require expensive treatment systems to make the wa-ter acceptable for domestic use.

D. Financial Status of any Operating Facilities

The residents of the entire area have private wells and furnish the operation and mainte-nance costs themselves.

E. Financial Status of any Operating Facilities

The existing demands for the proposed service area are as follows: Average Day 4,140 gpd Maximum Day 8,280 gpd Peak Hour 16,560 gpd

The future demands for the proposed service area will utilize a 2% increase per year. This increase takes into account population projections and the land use of the area.

IV. Need For Project

A. Health and Safety

The proposed water main project will provide safe potable water to the residents of the proposed Pratt Road Water District and will eliminate the health risks associated with the quality and quantity of ground water. The Genesee County Health Department began testing wells in the northeast area of the Town in March 2010 due to suspected manure contamination. The initial findings showed both bovine and human bacteria present in the wells. The results from the north-east area of the Town through April 28, 2010 include the following:

• 14 out of 38 tested positive for Bacteria • 12 out of 13 test results showed nitrate levels between 0.05 and 9.99 ppm, with

the remaining sample greater than 10 ppm.

As a result of the testing in the northeast area, the Town initiated well testing in other ar-eas with the following results:

• 11 out of 52 tested positive for Bacteria • 28 out of 47 test results showed nitrate levels between 0.05 and 9.99 ppm, and 3

out of 47 test results greater than 10 ppm.


A letter from the New York State Department of Health has been included as Appen-dix D.

B. System O & M

A water distribution network will replace highly expensive individual water treatment units; this will reduce the operation and maintenance costs borne by the residents at this time. Town of Batavia will provide operation and maintenance of the system.

C. Growth

While economic development is viewed as a project benefit, balancing economic devel-opment and land protection is necessary, critical, and provided for. The Town intends to limit water service connections within the boundaries of Agricultural Districts to only ag-ricultural structures or land and structures that have already been approved for development. Thus, there are no anticipated long-term impacts to the Agricultural Dis-tricts as a result of the proposed action including no change in use of agricultural/residential lands within the Agricultural District.

V. Alternatives Considered

A. Description

1. Alternative 1 – Null Alternative

This alternative proposes to “do nothing”. This would mean continued health risks for the residents of the proposed Districts.

2. Alternative 2 – New Water Distribution System

This proposed action includes the installation of approximately 16,000 lin-ear feet of 8-inch water main along Pratt and Powers Roads in the Town of Batavia. The water main will be PVC as the Town of Batavia utilizes PVC for their standard material. Various water main diameters were analyzed and the selected sizes were chosen based on providing adequate fire flows and taking into account future service areas. The proposed water main will be installed in the right-of-way in order to provide services to the residents on each side of the roadways.

3. Alternative 3 – Residential Well Supply

This alternative includes the establishment of a local source or multiple sources. The capital and long-term costs make this alternative prohibitive.


B. Design Criteria

The proposed Pratt Road Water District has been designed to provide safe potable water and fire protection to the Districts’ residents.

C. Map

Figure 1 shows the map of the proposed water system. The legal map has been provided in Appendix A.

D. Environmental Impacts

There are no anticipated environmental impacts associated with any of the alternatives. However, an environmental review will be completed for Alternative 2. All construction will be done in existing road-right-of-ways and proper construction mitigation and resto-ration efforts will be implemented.

E. Land Requirements

There are no additional land requirements for Alternative 2. All water main construction is anticipated to take place within existing road right-of-ways.

F. Construction Problems

There is no known construction problem for the new water system.

G. Cost Estimates (Total Capital Costs)

Alternative 1 Alternative 2 Alternative 3

$0 $937,200 $ 1,787,000

H. Advantages/Disadvantages

Alternative 2 is the most viable alternative as it is consistent with the goals and needs of the Town of Batavia. The advantage of Alternative 2 is as follows:

1. It will eliminate the ongoing health problems and risks associated with the quality

and quantity of ground water in the area. 2. It will create an alternate source of water for emergency use.


VI. Recommended Alternative

The recommended alternative is Alternative 2: New Water Distribution System.

A. Project Design

1. Water Supply

The proposed Pratt Road Water District will receive water from Genesee County and the City of Batavia water System. In case of emergency demands, the supply of water from the Town of Pembroke is received water from the MCWA.

2. Treatment

The City of Batavia Water Treatment Plant and the MCWA Shoremont Water Treatment Plant will provide treated water to the Alexander and Pike Road Water District. The treated water will meet all the state and federal drinking water standards. The ECWA will provide treated water in case of emergency demand flows to the proposed Pratt Road Water District. The treated water will meet all the state and federal drinking water standards.

3. Storage

A 1.5 and 1.25 million gallon water storage tank will provide the water storage needs for this Proposed District. No additional storage is required for this service area.

4. Pumping Stations

Pumps located at the City of Batavia Water treatment Plant and the North Road BPS pump water to the storage tanks and the distribution network.

5. Distribution Layout

The distribution network is shown in Figure 1 at the end of this report for the project area. The Town of Batavia will be responsible for system oper-ation and maintenance.


6. Services

The portion of the water service from the right-of-way to the main line will be installed under this project. The portion from the right-of-way to the home will be the responsibility of the homeowner.

7. Hydraulic Calculations

The hydraulic conditions of the proposed system were calculated using the WaterCad V8i hydraulic modeling software. The hydraulic analysis of the system includes the evaluation of available pressures and flows for the proposed Water District.

Hydraulic analysis of the system included the evaluation of available pres-sures and flows during minimum day (average day ÷ 4), average day, maximum day (average day x 2), and peak hour (average day x 6) demand conditions. This analysis also evaluated the available fire flows under maximum day demands and determined the age of the water in the distri-bution system.

The hydraulic analysis of the system indicates that adequate flows and pressures are available in the proposed system during average demand. Pressures in the new system range from 50 psi to 62 psi during average demand periods. The hydraulic analysis of the system indicates inadequate flows and pres-sures at the high point in the system during peak flow conditions at the intersection of Pratt and Powers Roads. The pressure at this location is un-der 20 psi when fire flows are approximately 460 gpm. At the required 500 gpm the pressures in the new system range from 17.8 psi to 45.3 psi. The relative low domestic demands on the proposed system would cause water quality issues if the size of the main was increased to a 12-inch di-ameter pipe. A secondary water source was determined the only option to supply ade-quate emergency flows and pressures to the new system. Investigation of alternative sources of water revealed the Town of Pembroke water distri-bution system was nearby. The proposed water distribution system design will include an 8-inch transmission main, beginning at the Pembroke Town line and continuing along Pratt Road until making the connection to the Pembroke water dis-tribution system near the intersection of Pratt and Indian Falls Road. The transmission main will be constructed of ductile iron pipe, the standard of the MCWA.


A pressure reducing valve (PRV) will be installed at the Pembroke Town line. The PRV will be designed to allow flows from the Town of Pem-broke water distribution system when the pressure in the proposed Pratt Road water district is below 35 psi. With the secondary source, fire flows will range from 770 gpm to 1,100 gpm in the proposed system while maintaining a minimum pressure of 20 psi. The project will meet NYSDOH standards and provide adequate fire flow.

B. Cost Estimate

The estimated total capital cost for the proposed service area is detailed in Appendix B and summarized as follows: Construction cost with 10% Contingency $767,000 Legal & Administrative Costs $36,700 Engineering Costs $53,500 Total Estimated Project Cost $937,200

Services During Construction $80,000

C. Town of Batavia Water Rate Information

1. The current water rate is $4.57 per 1,000 gallons of water used. 2. Quarterly water maintenance costs are $0.00 per 1,000 gallons. 3. Total rate equals $4.57 per 1,000 gallons.

D. Definition of a Unit

The Town of Batavia Water District Benefit Basis Unit Definition is included in Appendix C. The proposed district includes 32 units meaning they include single family hous-es, mobile homes, vacant land, manufactured homes, or non-residential properties.


VII. Annual Operating Budget A. Proposed Pratt Road Water District Unit Costs

The estimated average water district unit costs for the Town of Batavia are as fol-lows:

Capital Project Cost $937,200 Rural Development Grant $500,000 Total Debt $437,200 Annual Debt Service (38 years, 2.75%) $17,956 Annual Debt Service/Unit (24 units) $561 Average Annual Water Cost/Unit $288 ($4.42/1,000 gallons @ 63,000 gal. /year) Total Estimated Average Unit Cost $849 per year

B. Other Costs

Meter Charge $ 125 Service line $ 8-12/LF ($500 ave) Well abandonment or separation $ 200-600

VIII. Miscellaneous Information

A. Options for property owners well.

1. Abandon the well. 2. Keep well but separate it from public water plumbing. 3. Keep well and install backflow prevention.

B. Service line information

1. A service line will be installed to all residents. 2. There will be no future hook up charge for those that do not connect right

away. IX. Conclusions The Town of Batavia is committed to providing safe and reliable potable water supply to the res-idents in the project area. This specific project will be instrumental in achieving that goal.

Unit Definitions

Water District Benefit Basis

Unit Definition Each single-family residential dwelling shall be considered one unit. Included in this category will be single-family houses, mobile homes, and manufactured homes. Multiple single-family dwellings on the same parcel of land will each be considered an individual unit. Each additional livable area for apartments, duplexes, triplexes, etc. will be assessed 0.5 units for each additional livable area above the base unit of one. Seasonal or non-continuous occupancy will not be taken into consideration when determining what constitutes a unit. Any facility will be considered as a minimum of one unit. Vacant developable parcels will be assessed 0.1 units except for any vacant land currently in a certified Agricultural District. Non-residential, recreational, educational, commercial, industrial and agricultural facilities will be assigned an equivalent number of units based on the greater of the two methods as follows:

1. The average daily usage divided by 300 gpd (Average Daily Usage ÷ 300 = number of units).

2. Expected average daily usage (based on type of facility) divided by 300 gpd. Type of

facility and expected flow rates (gals/day) are listed below. (1):
