I. EXECUTIVE SUMMARY

The Town of Gorham (Town) Water Treatment Plant (WTP) was originally constructed in the 1960s. Over the past 50 years, the WTP has maintained efficient and effective water treatment. However, much of the existing facility is nearing or past its useful life, lacks redundancy and needs replacement. Additionally, recent source water concerns such as Harmful Algal Blooms (HABs), emergent contaminants such as perfluorooctanesulfonic acid / perfluorooctanoic acid (PFAS/PFOS), and high turbidity events have necessitated an evaluation of treatment operations, and potential adjustment to equipment and treatment processes. The Town has requested a technical evaluation of the WTP and Preliminary Engineering Report (PER) that provides feedback on existing operations, as well as recommendations for upgrades to provide a high level of water quality under various raw water conditions and provide additional treatment for HABs, emergent contaminants and high turbidity events. The PER will be compiled in accordance with the New York State Environmental Facilities Corporation (EFC) guidelines in order to seek funding for any noted capital improvements. After a full economic analysis considering the capital costs, the recommended improvements were separated into individual subprojects. The following table lists each subproject with an associated estimated cost.

Alternative Description Est. Cost

Alternative 1 System Upgrades $8.98 M

Alternative 2 Absorption Clarifier/Mixed Media filter

Package Plant $10.8 M

Alternative 3 Ultrafiltration Plant $7.97 M

Based on the overall analysis, Alternative 3 provides the most cost effective solution for water treatment for the Town and provides a high level of treatment for HABs, emergent contaminants and high turbidity levels. This solution also utilizes a modern SCADA system to assist in operations, conserves overall water volume throughout the treatment process, and has a relatively small footprint.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 2

According to 2020 United States Census Bureau data, the total estimated population for the Town was 4,469, the MHI was $63,218, and the poverty level was 11%. Therefore, the Town does not meet the criteria for hardship grant funding, but would likely qualify for subsidized financing through EFC grant opportunities. Due to the magnitude of the project, the Town would significantly benefit from a low interest loan and/or some grant funds to help offset these costs. It is recommended that this Preliminary Engineering Report be used to pursue funding assistance from multiple agencies, including the EFC through the Drinking Water State Revolving Fund (DWSRF) and Water Infrastructure Improvement Act (WIIA), USDA Rural Development (RD), and the New York State Office of Community Renewal, Community Development Block Grant (CDBG) program.

II. BACKGROUND

The Town of Gorham (Town)/Gorham Water District #1 owns and operates a Water Treatment Plant (WTP) located at 4285 New York State Route 364 at Crystal Beach and a water booster station on Turner Road. The water system includes a water storage tank on County Road 1, a water storage tank on Lake to Lake Road (with a booster station), and a distribution system that generally serves the hamlets of Crystal Beach and Gorham, and several roads within the Town of Gorham via the Gorham Water Districts. The Town also sells water to the Town of Hopewell. Although the WTP is operating fairly efficiently to meet current demands and providing treated water at or below mandated EPA quality thresholds, some of the existing equipment is old and outdated. There are seasonal algal blooms that create high turbidity influent to the treatment system, straining the existing DE filters. Therefore, the Town has requested a technical evaluation of the WTP that provides feedback on existing operations, as well as recommendations for upgrades and/or alternative treatment technologies. The following items were considered in the comprehensive analysis:

• Overall system capacity calculations based on existing and future development loads

• Age and condition of WTP components with respect to their intended useful life

• Discussion about existing intake pumping operations

• Condition of both raw and finished water quality and its impact on the community

• Treatment process calculations to determine maximum efficiency and redundancy

• Evaluation of filtration media and technology

• Environmental analysis of existing chemical treatment and disinfection processes

• Backwash and sludge removal efficiency in relation to discharge into Deep Run Creek or

the sanitary sewer system

III. PROJECT PLANNING A. SITE INFORMATION

The Town is located in Central Ontario County surrounded by Canandaigua Lake, the Town of Canandaigua, the Town of Hopewell, the Town of Seneca, the Town of Potter, and the Town of Middlesex. The Town has a total area of 53.2 square miles, of which 48.9 square miles is land and 4.3 square miles is water. The Town sits at the south border of the county, southeast of Canandaigua. The Water Treatment Plant (WTP) located at 4285 New York State Route 364.

B. ENVIRONMENTAL RESOURCES PRESENT According to the DEC online Environmental Resource Mapper tool, the WWTP is not located in an area that requires special environmental permitting. The only area of rare plants and animals is within the bounds of Canandaigua Lake. Neither the Town nor the WTP are located in an Environmental Justice area. The United States Geographical Survey (USGS) 7.5 minute series quadrangle maps and United States Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) were used to compile information regarding the topography, soil data, depth to any restrictive layer, depth to groundwater, and flooding considerations. According to USGS, the bedrock types surrounding the WTP are defined by the Ludlowville Formation (Dhld). The Town encompasses three surficial geologic types. The WTP is located on an area of Till (t), with variable texture from boulders to silt and variable permeability with compaction. According to data from USDA-NRCS, the WTP sits on soils made up of Guyanoga channery silt loam (15B), Honeoye loam (101C), Palmyra and Howard Soils (120E), and Lima loam (201B). Soil 15B is classified as Hydrologic Soil B. It has a slope ranging from 3 to 8%, a depth to water table between 36 to 72 inches, a depth to a restrictive soil layer of more than 80 inches, rare frequency of flooding, no frequency of ponding, low available water storage (about 5.0 inches), and is considered well drained.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 5

Soil 101C is classified as Hydrologic Soil B. It has a slope ranging from 8 to 15%, a depth to water table more than 80 inches, a depth to a restrictive soil layer of more than 80 inches, no frequency of flooding or ponding, moderate available water storage (about 7.4 inches), and is considered well drained. Soil 120E is classified as Hydrologic Soil B. It has a slope ranging from 25 to 45%, a depth to water table more than 80 inches, a depth to a restrictive soil layer of more than 80 inches, no frequency of flooding or ponding, low available water storage (about 5.5 inches), and is considered well drained. Soil 201B is classified as Hydrologic Soil B/D. It has a slope ranging from 3 to 8%, a depth to water table between 18 to 24 inches, a depth to a restrictive soil layer of more than 80 inches, no frequency of flooding or ponding, moderate available water storage (about 7.2 inches), and is considered moderately well drained. Therefore, depending on the required depth, there is no anticipated difficulty during construction. An extensive geologic survey is recommended for any proposed construction. Site location, Environmental Resource and Waterbody, bedrock and surficial geology maps, and soil maps and descriptions are included in Appendix A.

C. OWNERSHIP AND SERVICE AREA

Ownership The Water Treatment Plant is owned and operated by the Gorham Water District #1. Improvements to the WTP will be subject to Town Law 202-b. Service Area According to the 2012 Recommended Standards for Water Works (Ten States), the design period for new processes and equipment should be 20 years. Therefore, both recorded and projected population estimates were considered. Population data for the Town was obtained from the Genesee/Finger Lakes Regional Planning Council and the U.S. Census Bureau. Based on the data provided, the Town population makes up about 3.9% of the entire population of Ontario County. Therefore, this percentage was used to aid in the estimated projected populations:

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 6

Year Ontario County Population Town Population 2020 111,117 4,373 2030 113,818 4,479 2040 116,163 4,571

As shown, there is an expected increase in population of about 198 people between 2020 and 2040. Therefore, future design criteria will be based on a population estimate of approximately 5,000 people. This allows for a robust system to encompass unexpected economic or urban development. A summary of population estimates and projections are included in Appendix B. According to the 2019 Annual Drinking Water Quality Report, the Town Water Department serves approximately 4,950 people through 1,560 connections in the Towns of Gorham and Hopewell. The main source of drinking is Canandaigua Lake. The Hopewell Water District and the Town of Seneca provide back-up sources of water, purchased for water emergencies. The Hopewell system uses surface water, whereas the Seneca system uses groundwater. A copy of the 2019 Annual Drinking Water Quality Report is included in Appendix C. According to Ontario County Planning, the Town provides public water to three water districts. Review of the DEC water supply permits for the Town issued between 1964 and 2008 indicate there are more than thirteen water district extensions, most of which are associated with various subdivisions. Based on the location of water meters to water district boundaries, it is evident there are many users outside the district as well. A copy of the water distribution map is included in Appendix D.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 7

D. DESIGN CRITERIA

Based on review of discharge monitoring reports (DMR) from January 2019 through May 2021, the existing two- and half-year average flow is summarized in the table below.

Existing Conditions Flow Factor Average Daily Flow 0.46 MGD - Peak Month ADF 0.46 MGD 1.0 Peak Day 0.85 MGD 1.8

WTP Design Conditions Flow Factor

Design Capacity 1.50 MGD -

In order to determine potential growth and future demand on operations, historical and projected population data from the Genesee/Finger Lakes Regional Planning Council was analyzed up to the year 2040 for the Town of Gorham and Town of Hopewell. Based on these estimates, there was a potential increase in service area of 210 persons, which equates to a demand of 0.05 MGD. Therefore, the following future flows including water demand were considered:

Future Conditions Flow Factor Est. Average Daily Flow 0.52 MGD - Est. Peak Month ADF 0.51 MGD 1.0 Est. Peak Day 0.94 MGD 1.8

The estimated peak day at 0.94 MGD is conservative, but still far below the rated max capacity of the WTP at 1.50 MGD. Therefore, design calculations are calculated for both growth and development options, as well as the maximum permitted withdrawal limit from Canandaigua Lake to ensure the proposed improvements meet Ten States. A summary of the DMR data, and design criteria calculations and estimates are included in Appendix E.

E. EXISTING FACILITIES AND PRESENT CONDITION

The following sections outline the flow of water through the system, starting at Canandaigua Lake, through treatment, into storage, and out to distribution. An existing site layout and

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 8

process schematic are included in Appendix F. 1. Water Source

The Town obtains water from Canandaigua Lake under Water Supply Application No. 4788 issued in December 3, 1964. The Permit ID Number is 8-3232-0032/00013. According to the application, the WTP is permitted to withdraw up to a maximum of 1.5 MGD from the lake for use within the Gorham Water District. However, the actual diversion of water is limited to the existing capacity of the filter plant based on the design filter rate of 1.0 gpm/SF of filter area. In accordance with DEC and New York State Department of Health (DOH) standards, changes to the treatment process that allow withdrawal over 1.5 MGD, or increasing filter loading rate to be greater than 1.0 gpm/SF, require regulatory approval and modification of the water supply permit.

2. Water Treatment Plant The WTP is located at 4285 New York State Route 364. The treatment process consists of a raw water intake, raw water pumps, diatomaceous earth (DE) filters, and ultraviolet light (UV) reactor, chlorine gas, a clear well storage tank, and a high lift pump station. All unit processes are located inside a single building. The following sections summarize each of the components.

a. Raw Water Intake

The raw water intake consists of 1,175 feet of 12-inch steel pipe with an intake that is approximately 51.9 feet to 53.9 feet deep depending on the time of year. The intake can prove 1,320 gpm (1,9 MGD) at 5.8 feet of head loss when the lake is low. The raw water intake has sufficient capacity for existing and estimated future demands within the Town, the areas supplied in the Town of Hopewell, plus the Rushville/Middlesex water system.

b. Raw Water Pumps

The raw water pump station is located inside the WTP and contains two (2) pumps: 50 HP, Gould’s Model VIT-FFTM, size 8FLDLO, with 3 stages. Each pump is rated at 650 gpm at 235 feet, and 3,550 RPM.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 9

Flow from the raw water pumps is controlled by a variable frequency drive and a rate of flow control valve installed after the DE filters. Based on review, the pumps appear to operate at approximately 86.5% of speed (51.9 Hz); a single pump at full speed can provide up to 810 gpm, and both pumps at full speed can provide 1,320 gpm. Therefore, a single pump can provide the existing maximum day demand, but two pumps are required to meet peak hour demand. Additional pump capacity may be necessary to supply future system maximum day and peak hour demands.

c. DE Filters

The DE filters are an RP Adams Model IWF-269 four filter system with a capacity of 1,076 gpm with all four filters in service and loaded at 1.0 gpm/SF in accordance with the water supply permit. According to Ten States, the use of DE filters is best for application to surface waters with low turbidity and low bacterial contamination. At least two (2) filters should be provided, and the filters should be capable of meeting the WTP design capacity at the approved filtration rate with one filter removed from service. At 1.0 gpm/SF, this equates to approximately 807 gpm with one filter out of service. Ten States recommends a maximum filtration rate of 1.5 gpm/SF, which equates to approximately 1,210 gpm with one filter out of service. In order to increase the filtration rate from 1.0 gpm/SF to 1.5 gpm/SF, regulatory approval from the DOH would be required to increase the filter loading rate. Therefore, the existing DE filters can provide the average day demand with one unit out of service, while being loaded at 1.0 gpm/SF. Future maximum day demands would require all four filters to be in use.

It is important to note that the DE filter pre-coat on the bottom of the clear well should be cleaned and inspected to ensure the septum do not pass pre-coat media. According to Ten States, a uniform pre-coat shall be applied hydraulically to each septum by introducing a slurry to the tank influent line and employing a filter-to-waste or recirculation system.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 10

d. Wastewater (DE) Decant Basin

A dry feed system applies DE to the filters through the raw water pumps. When the headloss across the filters reaches a set point, the filters are backwashed to a wastewater decant basin adjacent to the WTP. The basin has an 8,900-gallon capacity at high water level. Filter backwash settles in the basin before being decanted to County Lake District Sewers adjacent to the plant. Decant drawdown volume is up to 5,050 gallons. Solids collected in the basin are routinely removed by the operator. The County Sewer District reports that DE frequently carries over from the decant basin to the County’s pump station to the immediate north of the WTP. The DE typically causes problems with the pump station necessitating maintenance. The county has requested any improvements to the WTP include provisions to eliminate the potential for DE reaching the pump station.

e. UV Reactor

Primary disinfection is provided by a single Trojan UV Swift TM 12 reactor with a design flow rate of 1,400 gpm and average flow rate of 400 gpm. The unit provides 40 mJ/cm2 based on a UV transmittance of 95%. According to Ten States, the installed unit provides the required dosage, but does not provide redundancy. In addition, the unit does not provide the required upstream and downstream pipe lengths.

f. High Lift Pumps

The two (2) high lift pumps are Gould VIT-DITM, 8RJHC 3-stage units with a design point of 650 gpm at 233 feet of head. Review of the system curve for the pumps determined that a single unit provides approximately 661 gpm at 228 feet of head during peak hour demands when Tank #1 is low. The flow increases to 1,249 gpm at 242 feet with both pumps operating. When system demands are low, Tank #1 level is high, and flow

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 11

from a single pump reduces to 590 gpm at 250 feet. The flow from both pumps is approximately 991 gpm at 278 feet.

The 1996 plans indicate that the maximum depth in the clear well is 2 feet. Literature provided by the manufacturer indicate that the minimum submergence required for the proper pump operation is 2.1 feet. Therefore, depending on actual operation conditions, the raw water pumps may cavitate when the clear well approaches the low level. The high life pumps can provide existing maximum day demand in the lower service area with one pump in service. Future maximum day demands would require both pumps to be in service. The high lift pumps cannot provide the anticipated peak hour demands with both pumps in service. Therefore, the lower service area relies on storage to supplement flow during peak hour demands.

g. Clear Well

The clear well is located below the WTP and shares a wall with the raw water wet well. The normal volume of the clear well is 49,900 gallons at high operating level. The operating volume is 40,600 gallons, and volume at low level is 9,300 gallons. The low-level volume was used for disinfection contact time calculations. Flow to the clear well is controlled by a rate of flow control valve with a maximum rate limited to the capacity of the DE filters of 1,076 gpm. Under normal operating conditions, with only one high lift pump on at a time, the clear well fills while producing water. When both pumps operate simultaneously, the clear well drains in approximately 3.9 hours. Based on these factors, the WTP appears to have sufficient capacity to supply daily demands. However, additional controls may be required to maintain a proper operating level for 3-log disinfection inactivation. During review of the WTP, the level sensor for the clear well appears to measure the depth above the low operating level and not the actual depth.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 12

The level sensor should be adjusted or replaced to measure actual depth. Review of the record drawings for the WTP revealed an opening in the wall between the clear well and the raw water wet well that serves as an overflow. The elevation of the overflow invert is 694.43 feet, approximately 7 feet above the Canandaigua Lake rule curve high water level of 687.34 feet. Therefore, this separation provides a sufficient air-gap to prevent backflow of raw water into the finished water storage.

3. Electrical Systems & Mechanical Systems

As part of the Preliminary Engineering Report phase, Jadestone Engineering was retained to perform an Electrical and Mechanical review of the building systems. Generally, the systems are from the original construction of the water plant and are at the end of their useful life. The generator is also undersized for the existing building loads and would presumably be undersized with any improvements. A copy of the electrical and mechanical evaluation is included in Appendix S.

4. Distribution System

The Town distribution system is comprised of asbestos cement, ductile iron, steel, and PRV pipe, ranging from 0.75 to 10 inches in diameter. Overall, the pipe is in good condition, with the number of breaks commensurate with the age of the system.

5. Water Storage The distribution system contains two (2) storage tanks, one in the Lower Service Area and one in the Upper Service Area. Water storage tanks should contain the following storage components:

• Operating Storage

The volume between pump on and pump off levels

• Equalization Storage The volume between pump on and the level needed to maintain 35 psi at all points

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 13

in the distribution system

• Fire Suppression Storage The volume between pump on and the level needed to maintain 20 psi at all points in the distribution system

• Standby Storage The volume between the levels needed to maintain 35 psi and 20 psi at all points in the distribution system

• Total Storage The volume between the overflow and the bottom of the tank

a. Lower Service Area

Tank #1 is located in the Lower Service Area, and provides system pressure

equalization and storage. Review of the tank and tank sizing guidelines

indicate that Tank #1 does not contain equalization of fire suppression

storage. This is primarily due to the ground elevations east of Summit

Parkway.

b. Upper Service Area

Tank #2 is located in the Upper Service Area, and provides system pressure equalization and storage. Review of the tank and tank sizing guidelines indicate that Tank #2 does not contain equalization storage. This is primarily due to the ground elevations along Depew Road between CR-17 and CR-18.

6. Turner Road Pump Station

The Turner Road pump station supplies water to the upper service area and fills Tank #2. Each pump is 50 HP with a design capacity of 600 gpm at 218 feet. Review of the system curves determined that a single pump can provide between 589 gpm at 253 feet of head and 661 gpm at 229 feet of head depending on system demands and tank water levels.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 14

With both pumps operating, the flow increases to between 992 gpm at 279 feet of head and 1,249 gpm at 242 feet of head depending on system demands and tank water levels. Therefore, the Turner Road pump station can adequately supply existing maximum day demand to the upper service area with one pump. Two pumps are required for peak hour demands. Comparison of the Turner Road pump station and high lift pump station indicates a similar capacity when one or two pumps are operating simultaneously. This indicates that during normal demands, when the same number of pumps are operating at each location, the system demands in the lower service area are supplied by Tank #1. In order to fill Tank #2, either both high life pumps need to operate while only one pump operates at Turner Road, or the one high lift pump can operate when the Turner Road pump station is off. The Turner Road pump station relies on a portable emergency generator stationed at the WTP for standby power in the event of a power failure. This generator also provides standby power for the WTP. It is recommended to install fixed generators at both locations to protect against a wide-spread power outage that may impact both facilities.

F. WATER QUALITY

To comply with New York State regulations, the Town issues annual drinking water quality reports. The purpose of the reports is to raise drinking water understanding and awareness needed to protect the drinking water source, Canandaigua Lake. In 2020, the Town conducted tests for various contaminants, including total coliform, inorganic compounds, nitrate, volatile organic compounds, and synthetic organic compounds. The following sections discuss leading water quality contaminants, and their impacts on the system. Copies of the Citizens Statewide Lake Assessment Program (CSLAP) reports are included in Appendix G.

1. Blue-Green Algae

According to the 2018 CSLAP report, cyanobacteria, or blue-green algae, had the highest populations in Canandaigua Lake. The water quality conditions indicate a low susceptibility to blooms, with frequent blooms along the shoreline or in open

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 15

water. The site confirms the majority of algal blooms occur three times a year during the summer months. These blooms typically last a few days. Excessive growth of algae can cause problems such as bad taste and odor, potential cyanotoxins from lysed cells, increased color and turbidity, and decreased filter run times. The blooms are often controlled by reducing farm runoff into the water source. Although the site does not report excessively high turbidity or odor issues, it is recommended to consider additional filtration to control or mitigate the potential for cyanotoxins and/or turbidity levels caused by excessive seasonal algal blooms.

2. Turbidity

Turbidity is caused by particles suspended or dissolved in water that scatter light, making the water appear cloudy or murky. Particulate matter can include clay and silt sediment, fine organic and inorganic matter, soluble colored organic compounds, algae, and other microscopic organisms. Turbidity is tested in drinking water distribution systems to measure the filtration process effectiveness. Turbidity is measured in Nephelometric Turbidity Units (NTUs), where a greater scattering of light indicates low water clarity, and a lower scattering of light indicates high water clarity. The EPA maximum treated turbidity reading is 0.3 NTU, and New York State regulations require the treated turbidity always be below 1.0 NTU.

According to the Annual Water Quality Report, the highest monthly average turbidity recorded before treatment was 3.9 NTU, which is below the 5.0 NTU Maximum Containment Level (MCL). The average treated turbidity recorded at the filters was 0.16 NTU, well below the EPA and New York State regulations.

3. Invasive Species

Invasive species reported in Canandaigua Lake include Eurasian Watermilfoil, Curly Leafed Pondweed, and Water Chestnut. Fishhook Waterflea, Chinese Mystery Snail, Asian Clam, Common Carp, Quagga Mussel, Zebra Mussel, and Scud have also been reported. According to the site, there are no significant impacts on the treatment process or disinfected drinking water effluent from these species. However, Canandaigua Lake has a high vulnerability for new invasive species based on the calcium levels and available public access.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 16

4. Disinfection

The EPA reaffirms its commitment to the current Safe Water Drinking Act, which includes regulations related to disinfection and pathogenic organism control for drinking water supplies. The Surface Water Treatment Rule requires treatment for Giardia lamblia (Giardia) and viruses of all surface water and groundwater under the direct influence of surface water. Public water systems are required to comply with a new operating parameter referred to as a CT value, which is the concentration of free chlorine multiplied by the physical contact time in the storage tank. The CT value is used as an indicator of the effectiveness of the disinfection process. This parameter depends on pH and temperature to remove or inactivate Giardia and viruses that could pass through water treatment unit processes. According to Title 10 of New York Code of Rules and Regulations (10NYCRR), Subpart 5-1, Section 5-1.30 of the State Sanitary Code, total treatment of the system must achieve at least 99.9% (3-log) removal or inactivation of Giardia cysts and 99.99% (4-log) removal or inactivation of viruses.

The current treated water sampling point is downstream of the treatment plant. In order to determine the most conservative contact time, it was assumed that as the temperature decreases, the pH increases, and the chlorine residual is at a maximum value. The maximum pH was 8.0 and the minimum temperature was 1.7 deg-C. The chlorine residual for each piece of equipment was measured on site. The baffling factors for the raw water intake, DE filters, and clear well were estimated at 0.9, 0.7, and 0.5 respectively.

CT calculations were evaluated for three (3) different flow rates: existing max day, design max day, and max WTP capacity. These flow rates were based on existing WTP operating data and design criteria. Based on the analysis, the existing treatment system far exceeds the 4-log inactivation requirement for viruses for all flow rates, but only passes the 3-log inactivation requirement for Giardia under existing max day of 0.85 MGD and design max day at 0.94 MGD. For the existing max WTP capacity at 1.5 MGD, the 3-log inactivation fails. Further, the existing treatment system does not provide

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 17

the required CT for treatment of Microcystin (MCLR) at existing average day flows. However, according to the EPA’s Surface Water Treatment Rule (SWTR), inactivation credits can be provided by filtration and UV. The max WTP capacity can only meet inactivation with the credits. Therefore, additional DE filters or a larger low-level operating volume in the clear well are required to meet the required CT time at these flow rates. Full CT contact time calculations are included in Appendix H.

5. Disinfection By-Products

Over the past years, the Environmental Protection Agency (EPA) has worked collaboratively with stakeholders to develop regulations that will provide a balance between the need to disinfect drinking water and the need to protect citizens from potentially harmful contaminants. The EPA has set MCLs for total trihalomethanes (TTHMs) and haloacetic acids (HAAs) of 80 and 60 micrograms per liter, respectively, based on annual averages of quarterly sample results taken from the distribution system. According to the Annual Water Quality Report, the average TTHM level recorded was 49 ug/L and the average HAA level recorded was 36 ug/L. Although none of the averaged TTHM data exceeds the EPA limit of 80 µg/L, there were samples above this point, ranging up to 100 ug/L. Therefore, it is important to implement improvements to address THM levels before distribution to the community.

6. Water Loss

Old and poorly constructed pipelines, inadequate corrosion protection, poorly maintained valves, and mechanical damage are some of the factors contributing to leakage. One important effect of water leakage, besides the loss of water resources, is reduced pressure in the system. Raising pressures to make up for these losses increases energy consumption as well as making leaking worse. In general, a 10 to 20% allowance for unaccounted water is normal. A loss of more than 20% requires priority attention and corrective actions.

Unaccounted water is the difference between water produced at the treatment facility and metered use by customers. In 2019, the total annual use drawn from

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 18

Canandaigua Lake and treated at the WTP was approximately 115.1 MG, whereas the total amount consumed was about 155.8 MG. Approximately 19.8 MG were accounted for due to water main failures, frozen meters and services, Fire Department usage, and flushing hydrants. Therefore, the total unaccounted loss for the system is about 13%, which falls within the normal range. In order to prevent future leaks, it is recommended to initiate leak detection efforts in the near future that focus on distribution policies that encourage conservation, public education programs, pressure reduction, requests for voluntary cutbacks or bans on certain water uses, and water recycling.

G. FLOOD PROTECTION

According to the FEMA Flood Insurance Risk Map effective December 5, 1996, the existing WTP is located in Zone C, which is representative of areas of minimal flooding hazards. However, the Flood Insurance Rate Maps are only an approximation.

Ten States requires that other than surface water intakes, all water supply facilities and water treatment plant access roads shall be protected to at least the 100-year flood elevation or maximum flood of record, as required by the reviewing authority. A freeboard factor may also be required by the reviewing authority. It is also important to consider the impact climate change may have on the 20 year design life of the WTP installations. Climate change may increase currently identified flood risks due to increased precipitation, larger run-off volumes, sea-level rise, and higher storm surges. As shown, any new equipment would be far above the 100-year flood level. A FEMA Flood Insurance Rate Map is included in Appendix I.

H. FINANCIAL STATUS

The 2018 American Community Survey Statewide Median Household Income (MHI) for New York State is $62,765, which is adjusted for certain counties by a Regional Cost Factor (RCF). The RCF for Upstate is 1.0, and therefore the adjusted MHI is $62,765. The 80% MHI is $50,212. The Drinking Water State Revolving Fund (DWSRF) hardship program offers both interest free and/or grant funding to eligible projects.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 19

According to 2020 United States Census Bureau data, the total estimated population for the Town was 4,469, the MHI was $63,218, and the poverty level was 11%. Therefore, the Town does not meet the criteria for hardship grant funding, even if given a high enough IUP listing. A summary of the Census Bureau data for the Town is included in Appendix J.

I. NEED FOR PROJECT

1. Health and Safety

The Town of Gorham has identified a need to provide treatment enhancements to counter changing source water conditions, including Harmful Algal Blooms, Emergent Contaminants (such as PFAS/PFOS), and high turbidity events. Blue Green Algae (BGA) has been detected in the source water since the summer of 2016. The Gorham WTP is the only facility on Canandaigua Lake that does not provide enough CT to treat for the most prevalent cyanotoxin: MCLR. Additionally, the DE filters are the most likely treatment type (in the presence of chlorine) to lyse cells releasing cyanotoxins.

2. Aging infrastructure

The Town of Gorham’s WTP was constructed in the late 1960s with the current DE

Filters. These filters are showing signs of disrepair and are near the end of their

useful life (50 years +/-). Any future project needs to include replacement of these

filters (in kind or otherwise).

a. Loss of source capacity

The Town of Gorham’s WTP experiences loss of capacity during high

source-water turbidity events as is typical of most DE filtration plants.

Additionally, HAB events also decrease the capacity of the WTP to

minimize the potential for lysing BGA cells. Any future project needs to

include treatment for HABs and high turbidity events.

3. Compliance with current design standards

The existing WTP was evaluated against Ten States Standards and found the

following:

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 20

• The DE Filters fail to provide the required redundancy with one (1) filter offline and meet the design flow of 1.5 MGD.

• The low lift (raw water) and high lift pumps do not provide the required redundancy at the design flow of 1.5 MGD.

• The clearwell lacks the necessary volume providing the required contact time to meet disinfection requirements at the design flow of 1.5 MGD.

• UV disinfection system fails to provide the required redundancy (single unit) and additionally does not comply with the installation requirements (straight pipe lengths upstream and downstream from the reactor) for the UV certification.

J. SYSTEM O&M

WTP and Distribution System Operation and Maintenance will continue to be the

responsibility of the Town of Gorham.

K. GROWTH

The water system design assumes a steady 1.5% annual increase in population in the Town

by the year 2040, based on documentation from the US Census Bureau and Genesee Finger

Lakes Regional Planning Council.

L. COMMUNITY ENGAGEMENT

The Town recently adopted the Gorham Water Master Plan prepared by MRB Group. The

Water Master Plan was presented to the public at a public hearing and after taking input from

the public, the planning document was adopted the next regular Town Board meeting. The

Water Master Plan identified several needs of the overall system, but the highest ranked

improvement was for upgrades to the WTP process to improve the resiliency under various

raw water conditions such as HABs, emergent contaminants and high turbidity events.

MRB Group Project No. 0735.21001.000 Page 21

IV. ALTERNATIVES ANALYSIS

Overall the WTP operates efficiently, however, the existing treatment system lacks redundancy and does not provide adequate treatment for HABs, emergent contaminates and high levels of turbidity. The existing DE filters are outdated, and do not sufficiently combat high turbidity. Due to the age of the system, various upgrades could provide redundancy to facilitate routine operation and maintenance, ensure a robust system, and provide for future growth. Based on the analysis of existing conditions and process data, the following sections outline system improvements, recommendations, and future capital projects as three varying treatment processes. All alternatives are designed with filter redundancy to be able to produce 1.5 MGD with a filter offline. Each alternative includes carbon filtration for treatment of cyanotoxins, emergent contaminants and potential taste and odor issues. All the alternatives consider a discharge to the County’s sewer and potentially Deep Run Creek. The existing sewer flows by gravity to a pump station of limited capacity. Design Criteria: The design criteria for each alternative will be consistent with “Recommended Standards for Water Works” (RSWW) or more commonly known as ‘Ten States Standards’ and/or the requirements and approval conditions of the NYSDOH. Each alternative considers the design flow of 1.5 MGD with a filter out of service and carbon filtration with at least 10 minutes of Empty Bed Contact Time (EBCT). Environmental Impacts: Each alternative will require the construction of a new Filter Building and an Equalization Tank of various sizes. Alternatives 1 and 2 may require a discharge to Deep Run Creek and a discharge to the County Lake Sewer District. Alternative 3 only requires a discharge to the county sewer. If necessary, the Town will work with NYSDEC and/or Ontario County to obtain any proper permits for those discharges. The SEQR/NEPA environmental review will document any design or construction constraints associated with archaeological sensitivity, endangered or threatened species, and rare plants or animals. A. ALTERNATIVE 1 – TREATMENT ENHANCEMENTS

Based on the varying turbidity levels over the course of the year, insufficient capacity for the existing DE filters, failure to meet Ten States standards for several thresholds, and the lack of redundancy to provide minimal risk during routine or unexpected operation and maintenance, Alternative 1 includes addition of pre-filtration, backwash recovery,

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 22

replacement DE filters, carbon filtration, and a redundant UV system, construction of a backwash equalization tank. This system would be rated for 1.5 MGD to be consistent with the maximum withdrawal permit of 1.5 MGD. Details for the proposed system upgrades, along with a process schematic are included in Appendix K.

1. Pre-Filtration

In order to combat high turbidity levels at the intake, pre-filtration in the form of multimedia pressure filters will be added. Eight (8) carbon steel painted pressure filters are proposed to meet the 1.5 MGD total design capacity. The filters are designed for flow rates between 640 and 1,910 GPM, with an anticipated backwash rate of 240 GPM.

2. DE Filters

The existing are outdated, and will be replaced. Each filter will contain filter elements totaling 240 SF or filter area. Each filter tank will be fabricated of 304 stainless steel DE Filters with stainless steel internals and filter elements for 100 pounds of pressure. Each filter will have 6-inch flanged connections.

3. Carbon Filtration

In order to add another layer of filtration, while addressing any potential taste and odor complaints, it is proposed to install two (2) granular activated carbon (GAC) filters following the DE filters. GAC is used to adsorb a variety of natural organic, synthetic organic, and taste and odor compounds. In this process, the porous media provides a large surface area for containment adsorption. Water from the DE filters will be introduced to each cell, where it passes through a bed of GAC media to remove constituents. The water then passes through an underdrain plate and exits the system as treated effluent to the UV system. Filter piping and valving for a multiple unit system can be arranged to account for parallel flow, series flow, or single-unit flow patterns. This allows the operator flexibility to operate as needed. As the media is spent, the level of constituent in breakthrough will increase, indicating replacement is required. Backwashing is used to remove dust and fines

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 23

after media replacement. It is proposed to send the backwash to the head of the plant and/or discharge to Deep Run Creek under a SPDES permit.

4. UV Disinfection

The proposed TrojanUVSwift™ ultraviolet system consists of an inline system with two (2) reactors. Each reactor contains two (2) lamps, for a total of 4 lamps. The system is rated for a peak design flow of 2.0 MGD, 95% UV transmittance, and a design does 40 mJ/cm2. A touch smart controller will be included for system control. The system includes the ActiClean™ automatic chemical and mechanical cleaning system. The proposed UV system, and associated electrical equipment will be housed inside an insulated pole barn structure to protect the equipment from direct sunlight and precipitation, and to assist in preventing algae growth.

5. Backwash Recovery

As part of future conservation efforts, and removal of excess solids, a backwash recovery system is proposed. The system will include an equalization tank and an inclined plate system. This system includes a combination rapid mix and flocculation tank. Water from the pre-filter units is fed to the rapid mix chamber, where coagulant is added to neutralize charge on the suspended particulates. Following a 30 to 60 second rapid mix period, the water flows over a baffle into the flocculation zone, where particles are gently mixed for approximately 5 to 10 minutes to promote collision and formation of larger flocs. The flocculated water then flows under another baffle to enter the separator transfer pipe under laminar flow conditions to the inclined plate basin. Water enters the inclined plate system at the base of the plates, where feed chemicals are specially designed to promote quiescent flow into the plates, minimizing re-entrainment of already settled solids. Water continues to slowly flow upwards through the plates, while solids settle and collect along each plate surface. Quiescent flow is critical for allowing the water to rise without affecting the settling velocity of the solids. As solids accumulate on the plate surface, they begin to slough off the plates and fall to the hopper at the bottom of the inclined plate basin.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 24

Solids collect at the bottom of the conical hopper, where an operator can blowdown the solids that have collected over time. Blowdown frequency is dependent on the solids loading to the system and how quickly the hopper bottom fills with settled solids. Sample taps at various heights are installed in the hopper to determine the level of solids and when blowdown is required. Settled solids are intermittently flushed from the sludge hopper and discharged. It is proposed to send supernatant from the backwash recovery system back to the head of the WTP, and the remaining waste will be sent to the sanitary sewer. The rate of discharge will be metered as to not overload the systems or exceed 10% of instantaneous raw water flow.

B. ALTERNATIVE 2 – ABSORPTION CLARIFIER AND MULTIMEDIA FILTER PACKAGE PLANT

Again, in order to combat varying turbidity levels and minimize strain on the existing filters, and minimize overall operations, Alternative 2 includes construction of a package plant. This system would include Trident® absorption clarifiers and filters to combat varying turbidity levels, a backwash recovery system, carbon filtration and UV to provide disinfection and algal toxin treatment. The Trident® filters would replace the existing DE filters. Details for the proposed system upgrades, along with a process schematic are included in Appendix L. 1. Package Plant

The Trident® system combines a variety of chemical treatment solutions, including a patented adsorption clarifier system and mixed media filter to deliver excellent predictable finished water quality. The system also includes a direct retention air/ water backwash underdrain system. Each system includes a program for continuous effluent quality control. Backwash will be sent to the backwash recovery system.

2. Backwash Recovery

As part of future conservation efforts, and removal of excess solids, a backwash recovery system is proposed. The inclined plate system includes a combination rapid mix and flocculation tank. Water from the pre-filter units is fed to the rapid mix chamber, where coagulant is added to neutralize charge on the suspended particulates. Following a 30 to 60 second rapid mix period, the water flows over a baffle into the flocculation zone, where particles are gently mixed for approximately

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 25

5 to 10 minutes to promote collision and formation of larger flocs. The flocculated water then flows under another baffle to enter the separator transfer pipe under laminar flow conditions to the inclined plate basin.

Water enters the inclined plate system at the base of the plates, where feed chemicals are specially designed to promote quiescent flow into the plates, minimizing re-entrainment of already settled solids. Water continues to slowly flow upwards through the plates, while solids settle and collect along each plate surface. Quiescent flow is critical for allowing the water to rise without affecting the settling velocity of the solids. As solids accumulate on the plate surface, they begin to slough off the plates and fall to the hopper at the bottom of the inclined plate basin. Solids collect at the bottom of the conical hopper, where an operator can blowdown the solids that have collected over time., Blowdown frequency is dependent on the solids loading to the system and how quickly the hopper bottom fills with settled solids. Sample taps at various heights are installed in the hopper to determine the level of solids and when blowdown is required. Settled solids are intermittently flushed from the sludge hopper and discharged. It is proposed to send supernatant from the backwash recovery system back to the head of the WTP, a portion of the supernatant to discharge in Deep Run Creek under s SPDES permit via a monitoring manhole, and the remaining waste will be sent to the sanitary sewer. The rate of discharge will be metered as to not overload the systems.

3. UV Disinfection

As with Alternative 1, the proposed TrojanUVSwift™ ultraviolet system consists of

an inline system with two (2) reactors. Each reactor contains two (2) lamps, for a

total of 4 lamps. The system is rated for a peak design flow of 2.0 MGD, 95% UV

transmittance, and the design is 40 mJ/cm2.

A touch smart controller will be included for system control. The system includes

the ActiClean™ automatic chemical and mechanical cleaning system. The proposed

UV system, and associated electrical equipment will be housed inside an insulated

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 26

pole barn structure to protect the equipment from direct sunlight and precipitation,

and to assist in preventing algae growth.

C. ALTERNATIVE 3 – ULTRAFILTRATION PLANT

In order to minimize overall operations, Alternative 3 includes construction of an ultrafiltration plant. This system would include ultrafiltration to combat varying turbidity levels and carbon filtration to address any potential cyanotoxins breakthrough or emergent contaminants as well as unwanted taste and odor. The ultrafiltration system would replace the existing DE filters and UV system. Details for the proposed system upgrades, along with a process schematic are included in Appendix M.

1. Ultrafiltration

The proposed ultrafiltration system consists of three (3) membrane filtration units sized to achieve a net production capacity of 1.5 MGD. Each unit has capacity for up to 34 modules, with 32 installed. The filtration process is an outside/inside, pressure-driven process to remove suspended solids and turbidity, and to achieve 4-log reduction of pathogens. Ultrafiltration membranes can also achieve greater than 1.5-log reduction of waterborne viruses. Raw water from Canandaigua Lake would be transferred to the feed tank. VFD-controlled feed pumps direct water to a 200 µm pre-filter for removal of larger debris. The feed pump controls will be configured to minimize flow variation between steps and instantaneous flux by operation of the maximum number of available units. Filtrate will then be sent to the backwash supply tank. Backwashing will be used to remove accumulated foulants by reversed inside/outside flow at an interval of 20 to 60 minutes with air scour for increased agitation. A drain or filter-to-waste step will be used to remove any additional accumulated material. Automated chemical cleaning will be performed biweekly to recover membrane permeability. Following chemical cleaning procedures, the membrane units are drained by gravity or a pressurized drain-to-waste, and waste is subsequently sent to the discharge location.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 27

Backwash water generated from the Ultrafiltration system will be discharged to an equalization tank and eventually the sanitary sewer. The rate of discharge will be controlled to not overwhelm the sanitary sewer.

2. Carbon Filtration

Carbon filtration is proposed to provide treatment of any potential cyanotoxins

breakthrough (from HABs), emergent contaminants and/or taste and odor issues.

The carbon system proposed will include two (2) granular activated carbon (GAC)

filters following the UF filters. The GAC filters are designed to provide ten (10)

minutes of EBCT at the design flow. Ten (10) minutes of EBCT is proposed since

UF provides a 78% reduction of cyanotoxins. GAC is used to adsorb a variety of

natural organic, synthetic organic, and taste and odor compounds. In this process, the

porous media provides a large surface area for containment adsorption.

Water from the DE filters will be introduced to each cell, where is passes through a

bed of GAC media to remove constituents. The water then passes through an

underdrain plate and exits the system as treated effluent to the UV system. Filter

piping and valving for a multiple unit system can be arranged to account for parallel

flow, series flow, or single-unit flow patterns. This allows the operator flexibility to

operate as needed.

As the media is spent, the level of constituent in breakthrough will increase,

indicating replacement is required. Backwashing is used to remove dust and fines

after media replacement. It is proposed to send the backwash to the head of the plant.

D. ADDITIONAL CONSIDERATIONS

The following sections discuss additional considerations for improvement in conjunction with the selection of one of the aforementioned alternatives.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 28

1. Pump Station Upgrades

With the addition of more complex treatment equipment and processes, it is recommended to upgrade both the low-lift (raw water) and high-lift pumps. The proposed high lift pumps include two (2) vertical turbine pumps each rated for 1,041 gpm at 245’ total dynamic head (TDH). The low-lift pumps are each rated for 1,041 gpm at 100’ TDH.

2. Filter Building

With the additional equipment, treatment systems, and infrastructure associated with

all three proposed alternatives, additional process space is required. Based on

available land space on the existing parcel, an insulated pole barn will be constructed

to house the new equipment. The filter building will also include laboratory space,

HVAC, mechanical and electrical rooms, an office, and a restroom for employees.

Any available space in the existing WTP building will be utilized if possible to

reduce overall energy costs.

3. Permitting

Coordination with the DEC and DOH will be required for all proposed system

improvements. Based on recent conversations with the DEC, once a SPDES

application is received, the DEC will begin drafting a permit, including a water

quality review for the receiving surface water. Any additional monitoring

requirements will be identified at this point.

Based on recent conversations with Ontario County, once final upgrade equipment

and processes are determined, the volume of potential waste effluent into the sanitary

sewer system will be quantified. Metering and monitoring operations will be

determined based on these findings, and regulated as needed in the future.

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 29

4. Chlorine Analysis

The presence of chlorine residual in drinking water indicates that a sufficient amount

of chlorine was added initially to inactivate bacteria and viruses, and that the water

is protected from recontamination during storage. The project will have a water

quality monitoring panel that includes online measurement of finished water

turbidity, free chlorine, temperature, pH and conductivity for the purpose of

optimizing the treatment process and recording finished water quality.

In the event that a discharge to Deep Run Creek is necessary, a chlorine (TOC)

analyzer will monitor/record the chlorine levels in the discharge. The proposed

colorimetric chlorine analyzer uses colorimetric DPD chemistry to continuously

monitor water for free or total chlorine. The analyzer will operate unattended for 30

days and is compliant with US EPA regulation 40 CFR 141.74. Monthly routine

maintenance can be performed in a few minutes, including changing reagents and

cleaning the colorimetric cell.

V. COST ESTIMATES

The following economic analysis includes review of water use and associated costs per dwelling and type of user, and cost estimates for the proposed improvement alternatives. A. CAPITAL COST ESTIMATES

The 2021 water budget was estimated at $796,625, with about $27,000 spent on source of supply and transmission/distribution equipment. Based on the comprehensive WTP analysis, the cost estimates are separated by alternative:

Alternative Description Est. Cost

Alternative 1 Prefilter & DE Filter $8.98 M

Alternative 2 Absorption Clarifier & Multimedia

Filter Package Plant $10.8 M

Alternative 3 Ultrafiltration Plant $7.97 M

Further details of the overall cost estimates for each alternative are included in Appendix N.

B. EDU ANALYSIS

An Equivalent Dwelling Unit (EDU) is defined as a one single-family residential household. It is the unit of measure by which a user could be charged for water services provided by the municipal water district. Non-residential facilities EDU’s are calculated based on their demand. Agriculture is assessed at 50% of a typical single-family home usage. The Town serves a population of 4,373 through 1,590 water service connections. This includes services to the hamlets of Crystal Beach and Gorham, and several roads within the Town of Gorham. The Town also sells water to the Town of Hopewell. In 2018, the total annual use for the service area was approximately 125,458,549 gallons, with an average daily use of 343,722 gpd. Based on the calculations for water use in the community, the average single-family

residential consumption rate was 123 gpd or roughly 44,895 gpm. Residential EDUs total

2,055 due to the significant water usage by seasonal residential properties (24%) from 133

water accounts equaling 672 EDUs. The water usage by Agricultural operations represents

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 31

a significant portion of the overall system demand at nearly 18%. The Town of Hopewell as

a wholesale user represents roughly 478 EDUs based on the annual water demand of

21,398,000 million gallons. Total system EDUs is roughly 3,033. The breakdown of EDUs

for all residential, commercial, institutional, and industrial users are as follows.

A copy of the 2020 water budget and full analysis of EDU calculations for the Town are included in Appendix O.

C. FINANCING OPTIONS

Current Town residents are charged a base water rate of $37.25 per quarter for up to 8,000 gallons, and $4.50 per 1,000 gallons additional. Out of district users are charged an additional 25 percent. The formula for calculating most quarterly bills is the base rate plus the quantity of water times the water rate.

The Drinking Water State Revolving Fund (DWSRF) and New York State Environmental Facilities Corporation (EFC) provides several options for funding opportunities through WIIA grant programs. The Town can submit the projects for one or both of these opportunities. The WIIA program provides a 60% match toward the total project cost, up to $3 million dollars. An analysis of the potential funding opportunities at both subsidized and market rates over 30-year loans, along with the latest water budget are included in Appendix P.

VI. RECOMMENDED AND SELECTED ALTERNATIVE

The recommended alternative is selected based on the following design criteria:

• Ten States Standards • Ability to provide treatment for HABs • Ability to provide treatment for Emergent Contaminates like PFOS/PFAS • Provides the simplest treatment scheme • Produces the least amount of wastewater • Overall footprint • Capital cost • Will reliably produce high quality water

Based on a comprehensive WTP evaluation, there are a number of alternative improvements or upgrades to improve overall efficiency and address the need for treatment enhancements for HABs, Emergent Contaminants and high turbid events; however, Alternative 3 provides a comprehensive solution and excels based on the design criteria above. Alternative 3 includes ultrafiltration filters and carbon filters to treat for HABs, emergent contaminants and high turbid events, while also addressing CT issues without the need for a separate UV disinfection system. This alternative requires a lesser volume of backwash for the overall treatment process than the other alternatives. The overall system requires a smaller footprint because membranes are very compact and efficient. Additionally, this project will include conversion from gas chlorine to sodium hypochlorite for chlorination. See Appendix T for the Proposed Site Plan. Further, a backwash recovery system and UV system are not needed; the backwash-holding tank is approximately 1/3 of the volume needed for the other alternatives. Ultrafiltration can provide up to 3-log removal of Giardia and Cryptosporidium as filtration credits per EPA Guidance Manual for Compliance with the Filtration and Disinfection Requirements for Public Water Systems Using Surface Water Sources (1991). The basis of design ultrafiltration system completed a NSF/ANSI Standard 419-2018 challenge test (dated August 15, 2019) in which the reported log removal credits for cryptosporidium was reported to be >5-log. The NSF official listing for the Toray Industries, Inc. membranes is a log removal value of 6.05 log. Once complete, the ultrafiltration system has fewer costs associated with operation and maintenance, and provides a robust solution

for future growth and development of the community and surrounding service areas. The following table summarizes the log removal credits under the ultrafiltration treatment alternative.

A. PROJECT SCHEDULE

The following is an estimated project schedule (weather dependent), under assumption that

DWSRF financing is available for 2022 and notification of WIIA grant funding by December

2021:

• Complete Pilot Study/Approvals: June 2022

• Complete Design and Permitting/Approvals: December 2022

• Complete Bidding: January/February 2023

• Construction: April / May 2023

• Complete Construction: Spring 2024

B. PERMIT REQUIREMENTS

The project may require permits from the NYSDEC for work in proximity or crossing

streams. The need for these permits will be determined during the design phase. The project

may require coverage under the NYSDEC SPDES General Permit for Storm Water

Discharges (Permit No. GP-0-15-002). Regulatory approval from the NYSDOH is also

required.

C. ENGINEER’S OPINION OF PROBABLE COST

The Engineer’s Opinion of Probable Cost is $7,970,000.00, presented in Section V. and

Appendix H of the PER for the recommended alternatives, including requisite construction

and non-construction costs. A 20% construction contingency is incorporated into the total

estimated project cost.

Legal, Administrative and Engineering Costs have been estimated at 25% of the construction

cost, which is within the typical range for projects of this nature. A preliminary breakdown

of non-construction costs is as follows. This breakdown will be finalized when the requisite

Agreements are signed.

• Administration ..................$ 235,000.00 • Legal .................................$ 40,000.00 • Engineering .......................$1,099,000.00

There is no separate annual O&M budget for the project. The Town collects O&M via an

ad valorem charge. The 2021 O&M charge is approximately $0.237 cents per 1,000 TAV.

The Ad valorem charge generates roughly $121,000 per year in revenue according to the

Town’s budget records for 2019 and 2020.

D. ANNUAL OPERATING BUDGET

1. Income

The Town will continue to maintain and operate the system and deliver water to its

customers on a retail /ad valorem basis. The Town’s retail charge will need to be

increased to account for the Short-Lived Assets identified below.

2. Annual O&M Costs and Financing

Estimated project financing has been developed based on the following assumptions:

• Total project cost is estimated at $7,970,000.00 as per the Engineer’s Opinion of

Probable Cost in Appendix N.

• The project would qualify for a WIIA grant of $3,000,000.00 from NYSEFC

Preliminary Engineering Report Town of Gorham Water Treatment Plant Improvements September 2021

MRB Group Project No. 0735.21001.000 Page 36

• The project would qualify for a Grant/Loan funding package of $7,970,000.00

via the DWSRF program. Loan terms were assumed for 30 years at 2.5%

(assumed subsidized interest rate).

The ad valorem O&M charge for the Town will be not be changed as a result of this

project. Commodity charges will be made to all users on a quarterly schedule and

based on their individual metered consumption times the Town adopted rates. The

debt service charge will be included in the quarterly bills. The current Town water

quarterly $37.25 for the first 8,000 gallons plus $4.50/1,000 gallons after. Table VI.1

represents a summary of the estimated annual costs to a “typical single-family

residential property” within the District.

3. Short-Lived Assets

The proposed project is a replacement water treatment system with a design life of

at least 30 years. There are no short-lived assets that would require expenditure of

capital dollars other than the normal O&M expenses associated with operating the

system. Table V-2 includes a summary of the Short-Lived Assets. O&M costs are

covered through the Town’s retail consumption rate structure and ad valorem charge.

VII. CONCLUSIONS AND RECOMMENDATIONS The Town of Gorham has provided a reliable and cost-effective potable water service to residents for 50+ years. There is a substantial need to replace the aging water treatment plant, as documented in this report. In order for this project to be reasonably affordable to residents, financing in accordance with the information in Table VI.1 is required. Based on the favorable disposition of all of the above factors, it is the recommendation of MRB to apply for DWSRF/RD funding and implement the program, accordingly. Town of Gorham is also encouraged to apply for a NYS Water Infrastructure Improvement Act (WIIA) program grant. Improvements to the WTP would be pursuant to Town Law section 202-b.

The Genesee-Finger Lakes Region of New York State..............................................................................................................7 Municipalities of the Genesee-Finger Lakes Region..................................................................................................................8

I. Introduction This report includes population projections out to the year 2050 for the all counties, cities, towns and villages in the Genesee-Finger Lakes Region. A top down approach was used, where the region was capped within New York State, and then each county within the region, and finally all the municipalities within the counties were finalized.

II. Methodology

The methodology was developed primarily by the Capital District Regional Planning Commission, and has been reviewed and agreed upon by the other Regional Planning Organizations within New York State.

The Population Projection Model involves two distinct stages: a quantitative first stage using a log-linear projection model set up in a MS Excel Workbook, and a qualitative second stage using non-quantitative judgments of the likelihood and extent of future population change within particular jurisdictions. The result is a final population projection for each county, and the towns and villages within it.

A. Quantitative Stage

The Log-Linear model — so-called because of its straight-line form when plotted and a logarithmic scale for X-axis measurements — uses historic population to forecast or project future population based on a logarithmic curve, which is the best general model for natural populations. The mathematical form of the model is:

Y = b0 + b1 × ln(X) where Y = the Dependent Variable population and X = the Independent Variable for the time period (years or index years). The Y-Intercept (point at which ln(X) = 0) is represented by b0, while b1 represents the Coefficient or slope of the natural logarithm (base e = 2.71828183) of X [ln(X)]. After converting the Independent Variable X into logs (log transformation), the Model is “fitted” by the standard (least squares) method of minimizing the sum of the squares of the deviations between the Model values and the actual values as in a Simple Regression Model.

1

Log-Linear models when used for forecasts project the historic rate of change of the actual data into the future at a steadily declining rate (i.e., historic growth or decline will continue, but at a lesser rate). Log-linear models are an excellent basis for population forecasts because they project average historic rates of change into the future in a manner consistent with the average changes in natural populations. While short-term population data will typically exhibit some variety of saw tooth pattern when charted, long-term population data usually follow a log-linear trend. The MS Excel Workbook requires input of historic (and optionally, Census-estimated) population data for the region’s nine counties and its towns and villages. The sum of the historic populations of the sub-divisions (counties) should equal the region total, as should each county’s town and village total equal the county population. Thus, in the case of a county and its Minor Civil Divisions (MCDs), a town may be divided into its constituent villages together with the town population outside of the villages. A MCD may also be divided into the population in group quarters (e.g., for prisons and dormitories) and the population in households to better reflect the diverse population trends of the defined sub-divisions. The Workbook model uses "Index Years" in place of actual years for computing the natural logs of the Independent Variables, with the first year, 1960, set equal to one (1960 = 1). The default "Log Index Factor" for each area and sub-division has been set to one, so that 1961 = 2, 1962 = 3, 1990 = 31, etc. Varying the Log Index Factor will change the slopes of the Population Trend, Initial Projections, and Final Projections for the area or sub-division selected because the absolute value of the slope of a log-linear model declines as the model’s X-values increase. Thus, entering a number greater than one (e.g., 2, so that 1961 = 3, 1962 = 5, etc.) as a Log Index Factor will result in smaller slopes (absolute value) for the Population Trend, Initial Projections, and Final Projections. Whereas entering a number less than one but greater than zero (e.g., 0.5, so that 1961 = 1.5, 1962 = 2, etc.) will result in larger slopes (absolute value). Once the historic (and estimated) data was entered and the Log Index Factor set, the Workbook Model computed the Log-Linear Population Trends of the data using simple regressions on the population data and the natural log of the Index Years. It next computed Initial Projections based on the Population Trends and the historic (and estimated) data. The Initial Projections are derived by computing the difference between the actual data and the Population Trend data for the last year of the actual data (either historic or estimated), and adding that difference to the coefficients of the Population Trends. This creates new trend lines that extend directly from the last year of the actual data and have the same shape (slopes) as the Population Trend lines. The final procedure in the Quantitative Stage is to force the sum of the sub-divisions to equal the area total for each projection year. Given the independently derived nature of the area and sub-division projections, the sum of the sub-division projections for any particular projection year will virtually never equal the area total. The Workbook Model computes for each projection year the value (factor) which, when applied to all sub-division projections, will yield a sub-division sum equal to the area total.

2

The use of a constant factor (0% < Factor £ 300%) applied to all of the sub-divisions within a projection year results in distributing the required gain or loss of population in proportion to each sub-division’s population size. The extent to which sub-divisions must be adjusted to equal the area total checks the reasonableness of the log-linear trend used in the quantitative model. Adjustment factors for one or more projection years that are much less than 90% or much greater than 110% may indicate a discrepancy between the trends fitted to the area total and the trends fitted to the sub-divisions. This may be reduced by changing the Log Index Factor or making Flat Revisions to area or sub-division values.

B. Qualitative Stage The projections derived from the Log-Linear Model provide a basis from which to further analyze the forces that affect population change in each area and sub-division, and are not necessarily intended to represent final population projections. There are many historic trends other than simple population which may give an indication of the direction and extent of future population change, including but not limited to: average persons per household, persons in group quarters, building permit issuances, new home construction, immigration and emigration patterns, and labor force data. In addition, there may be new development opportunities or constraints for particular jurisdictions embodied in zoning and sub-division regulations, economic development programs, and capital budgets for transportation facilities. Infrastructure is also looked at as an asset or liability to growth and development in the municipalities. As much of this information as possible has been considered in reviewing the projections derived from the Log-Linear Model for each jurisdiction, and changes made as appropriate. The forecasts first take into consideration the population occupying group quarters. The number of people occupying group quarters were removed from the total population for each county, town and village before being run through the Model and were then added in as a flat revision after the projections have been made. This ensures that the group quarter numbers, which are typically static, are not factored in as a population that will have a natural increase over time. New or expanded group quarters and the elimination or downsizing of group quarters are additionally taken into account as flat revisions.

Additional considerations used to modify forecast numbers after being run through the model are as follows:

Input/Output

This includes looking at the total number of births and deaths for each town and village. In addition, the number of people migrating into and out of the area was taken into consideration. The total number of people coming into the area, through new births and in migration, minus the number of people who have died or left the area yields a new population through 2010. The birth and death rates in addition to in and out-migration trends can therefore be used for evaluating and modifying the initial population projections through 2050.

3

Housing and Occupancy Data

Following the trends in new housing construction in the towns and villages gives another check to the projections obtained through the model. By utilizing data such as the: 1) number of new major subdivisions, which is classified by producing at least four lots, 2) total number of lots resulting from new major subdivisions, 3) persons per household, 4) vacancy rate, and 5) building permit activity, new population entering the municipality can be estimated. The number of new housing lots, minus the number of vacant housing units, is multiplied by the average persons per household for that municipality resulting in the number of new residents in the municipality. This trend can then be projected through 2050 and used to modify initial forecast numbers.

Land Use and Regulatory Considerations

Each municipality has unique circumstances that require special consideration. Since quantitative data alone cannot accurately portray the possibilities for future growth or development, additional information was acquired from town and village officials. This includes the acreage available for residential development, the existence and condition of infrastructure, municipal growth management policies and the land use and zoning of available land. A contact at each county was actively involved in providing this information and supplying additional comments that may assist in modifying the initial population projections. This information provides an overview of the growth potential for each municipality and is an indicator of the type of future development that is likely to occur. Therefore, the quantitative data was complemented by qualitative information resulting in the best forecast possible.

III. Review Process Each county planner has had the opportunity to review and comment on the methodology, initial projections, and final projections. Once the initial projections were completed, staff went to each county with supporting data and discussed modifications that needed to be made that the quantitative portion of the model would not take into consideration. All modifications that were made to the initial figures were recorded and a justification was given to the planners for review. At every stage, the county planners have been involved in the process and have given staff the critical support and information to make the best possible forecasts. A few points of discussion were brought up regarding the population projections, especially by the rural counties. The model, which is heavily dependent on historical data, may be more appropriate for non-rural areas. Rural towns and villages can increase their

4

population by a significant percentage as a result of a new mobile home park or new subdivision. Since many of the towns and villages have a very small base population, this type of new development would greatly impact the growth rate. However, this type of development is not as predictable in rural areas as it may be in more urbanized areas. Furthermore, much of the data collected for the qualitative portion of the methodology is not as significant in rural counties. For example, looking at the amount of land available for residential development in a rural town is not indicative of the potential for growth. Although some urban towns are inhibited by the amount of land available for new development, rural areas have more land available than is often in demand. These types of qualitative indicators were, therefore, not given as much consideration in the projection process.

IV. Genesee-Finger Lakes Region Trends The Genesee-Finger Lakes Region has been increasing in population since 1960. In the last 50 years, the population has increased by 30%, about 285,000 people. The future population is projected to increase as well but at a decreasing rate. It is projected the region will grow by 3.6% from 2010 to 2050, an increase of 44,394 people. Ontario County is projected to have the highest percent increase at 9.5%. Other counties with a higher rate than the region average include Orleans (8.0%), Wyoming (7.2%), Seneca (5.9%) and Livingston (4.1%). It is projected that Genesee (2.7%), Yates (3.0%) and Monroe County at 3.2% will fall slightly below the regional projected average. Having been the focal point for much of the region in the past 50 years, the projected population for Monroe County follows the regional trend of increasing at a decreasing rate. Monroe County has seen significant growth in the past, an increase of more than 180,000 people in the last 50 years. Recent trends show population moving outward and at a much slower rate. Overall, the population in the Genesee-Finger Lakes Region remains strong and it appears it will continue to be so in the future. Each county has remained stable with only slight increases and is projected to stay that way. The largest county, Monroe, decreased from 62.4% of the region's population in 1960, to 61.2% in 2010, to a projected 60.5% in 2050. The smallest county, Yates, went from 2.0% of the region's population in 1960, to 2.1% in 2010 is projected to remain constant at 2.1% in 2050.

V. Genesee County Trends Genesee County is made up of 13 towns, 6 villages and the City of Batavia and a portion of the Tonawanda Reservation. The projected rate of population is consistent with the historical patterns of the county. From 1960 to 1970 the population increased by 4,728. From 2000 to 2010 the population decreased by 291 people. As a percentage, the total gain through 2050 is projected to be 2.7%. The towns that are projected to have the greatest increase in population will be Batavia, LeRoy, and Bergen. These three towns, located in the northeast corner of Genesee County, have adequate land available for residential development and may see some migration from Monroe County. The population has historically been stable and will likely continue into the future. With a current population just under 16,000 people, the City of Batavia is the center of Genesee County. Although the historical trend has shown the decreasing rate to be declining, the projection still has the City slightly gaining population to 2020 then decreasing in subsequent decades. The City of Batavia has decreased in population by almost 2000 people since 1960 and is projected to gain just under 300 by the year 2050. The remaining towns and villages within Genesee County are projected to remain relatively stable, increasing or decreasing at an average rate around 0.5%.

VI. Livingston County Trends Historically, Livingston County has had exceptional growth within the Genesee-Finger Lakes Region. In fact, Livingston County had the second highest growth rate (48.4%) within the region in the last 50 years. The growth is projected to remain, but not at as high rate of the past. One problem encountered when gathering historical data for Livingston County, was a misplacement of group quarters data within Mount Morris from the 2000 Census. These numbers were corrected so that the overall population would not reflect the error. The majority of the towns and villages in Livingston County have a projected increase in population. The Village of Geneseo has the largest projected increase due to the presence of SUNY Geneseo. Towns such as Avon and Lima will see an increase in population, likely due to its location in the Region. Avon is expected to continue to have sizeable development due to its proximity to Interstate 390.

VII. Monroe County Trends Major population changes have been happening within Monroe County for many years, and that scenario will likely continue. From 1960 to 2010, the population increased by 157,957 (26.9%) and is projected to increase by 23,780 (3.2%) by 2050. Municipalities that are projected to have a decrease in population include the City of Rochester, the Town of Irondequoit and the Town/Village of East Rochester. These three places have seen declining population for many years and appears this trend will continue. The City of Rochester has plans for residential development throughout the City but it appears the population will continue to decrease, although at a decreasing rate. The Towns of Greece and Webster have been gaining the most population the past few decades. Although the Town of Greece is projected to increase at a relatively small rate (1.5%), they will likely pass 100,000 population by the year 2040. The Town of Webster has seen the most growth since 1990. The Town of Penfield is projected to increase approximately 2.0% while the Town of Perinton is projected to increase about 3.0% through 2050.

IX. Orleans County Trends Having been one of the Region’s fastest growing counties in the past, Orleans County is projected to continue to grow at high percentage rate. With an increase of 3,420 population through 2050, the average decennial rate of increase is projected to be 8.0%. Unlike the past, when the increase was credited to the county’s correctional facilities, the future growth rate appears to be based on the rise of seasonal houses being converted into year-round homes and the proximity to Monroe County. The Towns of Kendall, Murray and Clarendon all border Monroe County. Water lines along Route 531 appear to be promoting additional development in the eastern part of the county.

XII. Wyoming County Trends Wyoming County increased in population by nearly 10,000 from 1960 to 2000 but then experienced a decrease of -1,269 between 2000 and 2010. Migration patterns and lower birth rates have affected Wyoming County’s population, causing it have a lower total and rate of population increase The Town of Arcade is likely to continue to experience a population increase because of its inexpensive electric power that has facilitated economic and residential development. The projected total percent increase for the Town of Arcade is an average decennial rate of about 2.9%. The Town of Bennington is likely to experience some population growth as well because of its close proximity to a metropolitan center (City of Buffalo). It is likely that Bennington will have significant new public water in the coming decades and is projected to increase at an average decennial rate of about 2.0% through 2050. The Village of Castile also has inexpensive electric power and is actively pursuing a sewer system in the near future that could make it the most attractive community on the eastern part of Wyoming County.

XIII. Yates County Trends Yates County is considered rural with the Village of Penn Yan being its most populated community of approximately 5,100 residents in 2010. The projected trend is that the Village will decline in population but only at an average decennial rate of about 0.3% through 2050. After a loss of population in the 1990’s, Penn Yan stabilized by 2010 likely by the efforts in removing brownfields near Keuka Lake and replacing them with single family homes. The largest gain in population is projected to occur in the Town of Jerusalem with an increase of about 350 people at an average decennial rate of about 2.5% by 2050. With its proximity to Keuka Lake, Jerusalem is feeling the growth pressure of the 2000’s when many people started to convert seasonal homes into year round housing. Many retirees are migrating to Yates County as well. The Town of Middlesex has seen over a 50% increase in its population over the past 50 years and will likely continue to increase in the future but not at the same rate. Many people living in Middlesex are located close to Canandaigua Lake and commute to the City of Canandaigua for work. The decennial net increase is projected to be similar to the historical figures but the total percent increase through 2050 is projected to be minimal. The Town of Benton has seen a large increase in population due largely to the increase of the Mennonite population. The last two decades saw an increase of over 20% in total population but is projected to be much lower in the future given the agricultural base in the community.

APPENDIX C

WATER QUALITY

Where does my water come from, and how is it treated?

The Town of Gorham Water Department serves approxi-mately 4950 people through 1560 connections in the Towns of Gorham and Hopewell. The water supply for the Town of Gorham consists of one primary source and two secondary sources. The main source of drinking water is Canandaigua Lake. The surface water from the lake is piped into the Gor-ham Water Treatment Plant where it is treated using a Dia-tomaceous Earth Filtration System and Chlorination to remove turbidity and mi-croorganisms. The water is also treated with ultraviolet disinfection equipment. The Hopewell Water Dis-trict and the Town of Se-neca provide our back-up sources of water. The back up sources are purchased for water emergencies. The Hopewell system uses surface water and the Seneca system uses groundwater. The back-up systems were minimally used during the 2019 year.

The NYS Department of Health completed a source water assessment of our water. This assessment found a moderate susceptibility to contamination for this source of drinking water. The amount of agricultural lands in the assessment area results in elevated potential for protozoa, phosphorus, DBP (disinfection byproduct) precursors, and pesticide contamination. There is also a moderate density of sanitary

wastewater discharges, but the ratings for the individual discharges do not result in elevated suscepti-bility ratings. However, it appears that the total amount of wastewater discharged to surface water in this assessment area is high enough to further raise the potential for con-tamination (particularly for proto-zoa). There are no noteworthy contamination threats associated with other discrete contaminant sources.

In general, the sources of drinking water (both tap and bottled water) include rivers, lakes, streams, ponds, reser-voirs, springs and wells. As water travels over the surface of land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activities. Contaminants that may be present in source water include: microbial contaminants; inorganic contaminants; pesticides and herbicides; organic chemical contaminants; and radioactive contaminants. In order to ensure that tap water is safe to drink, the State and EPA prescribe regulations which limit the amount of certain contaminants in water provided by public water systems. The State Health Department’s and the FDA’s regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

2019 Town of Gorham Annual Water Quality Report

Public Water Supply ID#: 3401170

Mr. Greg Coston, Chief Operator

Town of Gorham Water Department

P.O. Box 224

Gorham, NY 14461

Phone: 585-394-1580

The Town of Gorham annually issues a re-

port describing the quality of your drinking

water. The purpose of this report is to raise

your understanding of drinking water and

awareness of the need to protect our drink-

ing water sources. Included are details

about where your water comes from, what it

contains, and how it compares to NYS Stan-

dards. We want you to be informed about

your drinking water.

Annual Water Usage and Cost

The Town of Gorham had an annual water usage of 155,801,000 gallons in 2019. We successfully delivered 115,099,655 gallons to customers. The annual water loss for 2019 was 40,701,345 gallons. All but 19,849,942 gallons have been accounted for. Some loss was due to water main failures, frozen meters and services, Fire Department usage, use by churches, flushing hydrants, etc. Unaccounted losses were 12.7 % this year. For the year of 2019 the average cost of water, per family, was $400.00 per year.

Water Conservation

Water conservation helps the environment by preserving this natural resource. You can conserve water by:

Checking for and repairing leaks inside and out.

Checking your toilet for leaks (put a few drops of food coloring in the tank, if the color shows up in the bowl within a few minutes, you have a leak) Making repairs can save 30,000 gallons of water a year.

Replacing older fixtures with water saving showerheads, faucet aerators, toilet dams, or low flush toilets.

Using swimming pool covers to minimize evapora-tion

Watering lawns less frequently and preferably early in the morning or late in the evening.

Turning off the tap when brushing your teeth.

If you use an automatic dishwasher, waiting to run it until it is loaded to capacity.

GET INVOLVED!

As you can see from the table, we had no viola-tions this year. Some people may be more vul-nerable to disease causing microorganisms or pathogens in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing che-motherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infec-tions. These people should seek advice from their health care provider about their drinking water. EPA/CDC guidelines on appropriate means to lessen the risk of infection by crypto-sporidium, giardia, and other microbial patho-gens are available from the Safe Drinking Wa-ter Hotline, 1-800-426-4791.

The Town of Gorham is required to monitor your drinking water for specific contaminants on a regular basis. Results of regular monitor-ing are an indicator of whether or not your drinking water meets health standards.

If you have any questions about this report or your water utility, call Greg Coston at 585-394-1580 or the NYSDOH at 315-789-3030.

In the 2019 year, the Town of Gorham con-ducted maintenance work on equipment throughout the water system. In addition cus-tomer water meters have been upgraded to a remote read system that provides capabilities of detecting water leaks.

In the year 2020, the Town, will be continuing maintenance to the existing equipment and distribution system. The Town is investigating the use of carbon filters to provide additional treatment of Canandaigua Lake water.

If you are interested in opportunities to become more involved with your water supply, the Canandaigua Lake Watershed Commission holds its meetings on the third Tuesday of January, March, June, September, and Decem-ber. For more information contact Jim Abra-ham or Gordy Frieda at the Canandaigua Hur-ley Building, 205 Saltonstall Street, Canandai-gua, NY 14424 or 585-396-5060.

TESTING RESULTS FOR 2019—TABLE OF DETECTED CONTAMINANTS As you review the results, keep in mind that all drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline at 1-800-426-4791. As state regulations require, the Town of Gorham routinely monitors your drinking water for various contaminants. These contaminants include total coliform, inorganic compounds, nitrate, volatile organic compounds and synthetic organic compounds. The contaminants detected in your drinking water are included in the following table. The State allows us to monitor for some contaminants less than once per year because the concentrations of these contami-nants do not change frequently. Some of our data, though representative, is more than one year old.

*During 2017 we collected and analyzed 21 samples for lead and copper. The level included in the table represents the 90th percentile of the 21 sites tested. A percentile is a value on a scale of 100 that indicates the percent of a distribution that is equal to or below it. The 90th percentile is equal to or greater than 90% of the lead values detected at our water system. One site exceeded the action level for lead. The action level for copper was not ex-ceeded. **Highest monthly average. ***MLC for combined Radium 226 & 228. A MCL violation occurs when the annual composite of four quarterly samples or the average of the analysis of four quarterly samples exceeds the MCL. ****This level represents the highest locational running annual average calculated from data collected.

MCL - (Maximum Contaminant Level) - The highest level of a contaminant that is allowed in drinking water. AL - (Action Level) - The concentration which, if exceeded, triggers treatment or other requirements which

MCLG - (Maximum Contaminant Level Goal) - The level of a contaminant in drinking water below which there is no known expected risk to health. MCLGs allow for a margin of safety. MCLs are set as close to the MCLG as possible. MRDL - (Maximum Residual Disinfectant Level) - The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. MRDLG - (Maximum Residual Disinfectant Level Goal) - The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contamination. Turbidity - A measure of the cloudiness of water. It is a good indicator of the effectiveness of a filtration system.

Definitions TT - (Treatment Technique) - A required process intended to reduce the level of a contaminant in drinking water. pCi/L - (Picocuries per liter) - The measure of radioactivity in water. NTU - (Nephelometric Turbidity Units) - A measure of the clarity of water. Turbidity in excess of 5 NTUs is just noticeable to the average person. mg/l - (Milligrams per liter) - Corresponds to one part of liquid in one million parts of liquid (parts per million - ppm). ug/l - (Micrograms per liter) - Corresponds to one part of liquid in one billion parts of water (parts per billion - ppb). ND - Not Detected. NA - Not Applicable.

CSLAP sampling summary- Canandaigua Lake (S2), 2018 Q. What is the condition of the lake? A. Canandaigua Lake continues to be mesoligotrophic, or moderately unproductive, based on moderate water clarity, moderate algae levels (chlorophyll a), and low nutrient (phosphorus) levels. Soluble nutrients were analyzed for the first time in 2017. Some of the phosphorus in the lake is soluble, indicating some potential for more algae growth. Most of the nitrogen in the lake is soluble. The lake has slightly alkaline, extremely hard water, low water color, and moderately low nitrogen levels. Q. How did 2018 compare to previous years? A. Water clarity was slightly higher in 2018 than in 2017, consistent with lower algae and phosphorus levels (and despite higher conductivity and lower TN levels). However, annual changes are difficult to detect with only two years of data. Q. How does this lake compare to other nearby lakes? A. Compared to other nearby lakes, Canandaigua Lake usually has higher water clarity and conductivity, and lower pH, chlorophyll a levels and phosphorus readings. Canandaigua Lake usually has similar water quality and recreational assessments, and similar aquatic plant coverage. Water quality conditions are similar in the north and south CSLAP sampling sites. Productivity may be slightly higher in the northern end, based on slightly lower water clarity, although most of the other water quality indicators do not show a significant difference between these sites. Q. Are there any (statistically significant) trends? A. With only two years of data, long-term trends can’t be evaluated. Q. Has the lake experienced harmful algal blooms (HABs)? A. Water quality conditions indicate a low susceptibility to blooms, with frequent blooms along the shoreline or in the open water. The open water algal community in the lake is usually comprised of low cyanobacteria levels. Overall open water algae levels are low to intermediate. Open water toxin levels are consistently below recreational levels of concern. Shoreline blooms have been documented in the lake, comprised primarily of cyanobacteria comprised of Microcystis, with lesser amounts of Dolichospermum (previously called Anabaena) and Woronichinia. The shoreline algal community exhibits periodically high toxin levels.

In 2018, overall algae levels were low to intermediate, with diatoms the most common taxa in open water samples, and with low cyanobacteria levels. Open water toxin levels were undetectable. Shoreline blooms in 2018 were documented in the lake, generally at the South end of the lake, comprised primarily of cyanobacteria with high toxin levels. This led to a drinking water advisory for the Village of Rushville. The most common taxa were the same as reported in previous years. Q. Have any aquatic invasive species (AIS) been reported? A. There are invasive plants reported or present at Canandaigua Lake, and invasives have been reported in nearby waterbodies. Invasive species reported in the lake include Eurasian watermilfoil, curly leafed pondweed, water chestnut, and starry stonewort. Fishhook waterflea, Chinese mystery snail, Asian clam, common carp, quagga and zebra mussel, and scud have been reported in Canandaigua Lake. Canandaigua Lake has high vulnerability for new invasives, based on calcium levels, the presence of multiple AIS, and available public access. Q. Are any lake uses likely to be affected by these conditions? A. Canandaigua Lake supports potable water, recreation and public bathing use. It is likely that many of the actual or potential impacts described below are present in some parts of the lake, particularly the north end, and not present in other parts of the lake. Public water supply is stressed by drinking water advisories, and impacted by shoreline HABs and raw water cyanotoxins. Public bathing and recreation are stressed by shoreline cyanotoxins, and impacted by shoreline and open water HABs. Aquatic life is threatened by the presence of invasive animals. Aesthetics are poor due to HABs, and impacted by less than favorable recreational and water quality perception, and the presence of invasive aquatic plants. Habitat is fair due to the presence of invasive aquatic plants, although these conditions may be worsening due to the spread of starry stonewort. Fish Consumption use is considered to be unassessed. There are no health advisories limiting the consumption of fish from this waterbody (beyond the general advice for all waters). However, due to the lack of actual fish sampling data, fish consumption use is noted as unassessed, rather than fully supported but unconfirmed.

How to Read the Report This guide provides a description of the CSLAP report by section and a glossary. The sampling site is

indicated in the header for lakes with more than one routine sampling site.

Physical Characteristics influence lake quality:

• Surface area is the lake’s surface in acres and hectares.

• Max depth is the water depth measured at the deepest part of the lake in feet and meters.

• Mean depth is either known from lake bathymetry or is 0.46 of the maximum depth.

• Retention time is the time it takes for water to pass through a lake in years. This indicates

the influence of the watershed on lake conditions.

• Lake classification describes the “best uses” for this lake. Class AA, AAspec, and A lakes may

be used as sources of potable water. Class B lakes are suitable for contact recreational

activities, like swimming. Class C lakes are suitable for non-contact recreational activities,

including fishing, although they may still support swimming. The addition of a T or TS to any

of these classes indicates the ability of a lake to support trout populations and/or trout

spawning.

• Dam classification defines the hazard class of a dam. Class A, B, C, and D dams are defined as

low, intermediate, high, or negligible/no hazard dams in that order. “0” indicates that no

class has been assigned to a particular dam, or that no dam exists.

Watershed characteristics influence lake water quality:

• Watershed area in acres and hectares

• Land use data come from the most recent (2011) US Geological Survey National Land Use

Cover dataset

CSLAP Participation lists the sampling years and the current year volunteers.

Key lake status indicators summarize lake conditions:

• Trophic state of a lake refers to its nutrient loading and productivity, measured by

phosphorus, algae, and clarity. An oligotrophic lake has low nutrient and algae levels (low

productivity) and high clarity while a eutrophic lake has high nutrient and algae levels (high

productivity) and low clarity. Mesotrophic lakes fall in the middle.

• Harmful algal bloom susceptibility summarizes the available historical HAB data and indicates

the potential for future HAB events.

• Invasive vulnerability indicates whether aquatic invasive species are found in this lake or in

nearby lakes, indicating the potential for further introductions.

• Priority waterbody list (PWL) assessment is based on the assessment of use categories and

summarized as fully supported, threatened, stressed, impaired, or precluded. Aesthetics and

habitat are evaluated as good, fair, or poor. The cited PWL assessment reflects the “worst”

assessment for the lake. The full PWL assessment can be found at

http://www.dec.ny.gov/chemical/36730.html#WIPWL.

Current year sampling results

• Results for each of the sampling sessions in the year are in tabular form. The seasonal change graphically shows the current year results. Red shading indicates eutrophic readings.

• HAB notification periods on the DEC website, updated weekly http://www.dec.ny.gov/chemical/83310.html

• Shoreline HAB sample dates and results. Samples are collected from the area that appears to have the worst bloom. Red shading indicates a confirmed HAB.

• HAB sample algae analysis. Algae types typically change during the season. These charts show the amount of the different types of algae found in each mid-lake or shoreline sample. Samples with high levels of BGA are HABs. The second set of charts show the level of toxins found in open water and shoreline samples compared to the World Health Organization (WHO) guidelines.

• If there are more than ten shoreline bloom samples collected in a year, bloom sample information is instead summarized by month (May-Oct.) as minimum, average, and maximum values for blue-green algae and microcystin.

Long Term Trend Analysis puts the current year findings in context. Summer averages (mid-June

thru mid-September) for each of the CSLAP years show trends in key water quality indicators. The

graphs include relevant criteria (trophic categories, water quality standards, etc.) and boundaries

separating these criteria.

In-Season Analysis shows water temperature and water clarity during the sampling season. These

indicate seasonal changes and show the sample year results compared to the typical historical

readings for those dates.

The Lake Use Scorecard presents the results of the existing Priority Waterbody List assessment for

this lake in a graphical form and compares it to information from the current year and average

values from CSLAP data and other lake information. Primary issues that could impact specific use

categories are identified, although more issues could also affect each designated use.

The Lake Summary reviews and encapsulates the data in the lake report, including comparisons to

historical data from this lake, and results from nearby lakes.

Glossary of water quality and HAB indicators

Clarity (m): The depth to which a Secchi disk lowered into the water is visible, measured in meters.

Water clarity is one of the trophic indicators for each lake.

TP (mg/L): Total phosphorus, measured in milligrams per liter at the lake surface (1.5 meters below

the surface). TP includes all dissolved and particulate forms of phosphorus. TSP, or total soluble

phosphorus, was collected in 2018 and discussed in the lake narrative section.

Deep TP: Total phosphorus measured in milligrams per liter at depth (1-2 meters above the lake

bottom at the deepest part of the lake)

TN: Total nitrogen, measured in milligrams per liter at the lake surface. TN includes all forms of

nitrogen, including NOx (nitrite and nitrate) and NH4 (ammonia).

N:P Ratio: The ratio of total nitrogen to total phosphorus, unitless (mass ratio). This ratio helps

determine if a lake is phosphorous or nitrogen limited.

Chl.a (µg/L): Chlorophyll a, measured in micrograms per liter. Indicates the amount of algae in the

water column. This is an extracted chlorophyll measurement.

pH: A range from 0 to 14, with 0 being the most acidic and 14 being the most basic or alkaline. A

healthy lake generally ranges between 6.5 and 8.5.

Cond (µmho/cm): Specific conductance is a measure of the conductivity of water. A higher value

indicates the presence of more dissolved ions. High ion concentrations (> 250) usually indicate

hardwater, and low readings (< 125) usually show softwater.

Upper Temp (°C): Surface temperature, measured in degrees Celsius

Deep Temp (°C): Bottom temperature, measured in degrees Celsius

BG Chl.a (µg/L): Chlorophyll a from blue-green algae, measured in micrograms per liter. This is an

“unextracted” estimate using a fluoroprobe. This result is not as accurate as the extracted

chlorophyll measurement described above.

HABs: Harmful Algal Blooms. Algal blooms that have the appearance of cyanobacteria (BGA)

BGA: Blue-green algae, also known as cyanobacteria

Microcystin (µg/L): The most common HAB liver toxin; total microcystin above 20 micrograms per

liter indicates a “high toxin” bloom. However, ALL BGA blooms should be avoided, even if toxin levels

are low.

Anatoxin-a (µg/L): A toxin that may be produced in a HAB which targets the central nervous system.

Neither EPA nor NYS has developed a risk threshold for anatoxin-a, although readings above 4

micrograms per liter are believed to represent an elevated risk.

Water Quality Assessments

The Waterbody Inventory/Priority Waterbodies List (WI/PWL) is a statewide inventory of New York's water resources that is used to track a waters ability to support its’ best use(s), identify pollutant(s) causing impairment of best use(s), and follow the status of restoration, protection and other water quality activities and efforts. Data collected through CSLAP contributes to the WI/PWL. In order to be included as an assessment unit in the WI/PWL, a lake, pond, or reservoir must be at least 6.4 acres in size.

To view current water quality assessment results: o Visit https://www.dec.ny.gov/pubs/109457.html - follow the link to launch the DECinfo Locator o Search for waterbody name, address or nearby landmark in the search tool at the top of the left

banner o Click and Expand the ‘DEC Information Layers’ tab of the left banner o Click and expand the 'Environmental Monitoring' tab of the left banner o Check the 'Lakes and Reservoirs' layer o Click on the waterbody of interest in the map view to display a pop-up with more information

about the waterbody o Follow the 'Fact Sheet' link in the pop-up to learn more about the current use assessment of the

waterbody

Lake Stewardship Actions

Individual stewardship activities can help improve water quality: maintain your septic system, reduce

fertilizer use, grow a buffer of native plants next to the lake shore, and reduce shoreline erosion and

runoff into the lake. Visiting boats should be inspected to prevent the spread of invasive species, and

continued community education about and monitoring for invasive species is recommended. Routine

education about algae and harmful algal blooms (HABs) within your lake community is recommended; to

learn more about HABs and see examples of HABs visit http://www.dec.ny.gov/chemical/81962.html.

Occurrences of HABs can be reported to NYSDEC. For more information on keeping New York waters

clean, visit http://www.dec.ny.gov/public/43661.html.

Canandaigua Lake - 2019 Lake Summary

Q. What is the condition of the lake? A. Canandaigua Lake - North Site continues to be mesoligotrophic, or moderately unproductive, based on moderate water clarity, moderate algae levels (chlorophyll a), and low nutrient (phosphorus) levels. Soluble nutrients were analyzed again 2019. Most of the nitrogen in the lake is soluble, indicating a potential for more algae growth. The lake has slightly alkaline, extremely hard water, low water color, and moderately low nitrogen levels. Q. How did 2019 compare to previous years? A. Calcium readings were lower than normal in 2019. Each of the other water quality indicators was close to normal in 2019. Q. How does this lake compare to other nearby lakes? A. Compared to other nearby lakes, Canandaigua Lake - North Site usually has higher water clarity, conductivity, calcium levels, and chloride levels, and lower chlorophyll a levels and phosphorus readings. Canandaigua Lake - North Site usually has similar water quality assessments, similar recreational assessments, and similar aquatic plant coverage. Q. Are there any (statistically significant) trends? A. Since 2017, there have been no significant water quality trends. Q. Has the lake experienced harmful algal blooms (HABs)? A. Water quality conditions generally indicate a low susceptibility to blooms, though frequent blooms along the shoreline or in the open water have been documented. The open water algal community in the lake is usually comprised of low cyanobacteria levels. This community is dominated by Microcystis. Typically, open water algae levels are intermediate. Overall open water toxin levels are consistently below recreational levels of concern. Shoreline blooms have previously been documented in the lake, comprised primarily of cyanobacteria dominated by Microcystis. The shoreline algal community typically exhibits high toxin levels.

In 2019, overall algae levels were intermediate, with green algae the most common taxa in open water samples, and with intermediate cyanobacteria levels. Open water toxin levels were at times low but detectable in 2019. Shoreline blooms in 2019 were documented in the lake, comprised primarily of cyanobacteria with high toxin levels. The most common taxa were Microcystis. Q. Have any aquatic invasive species (AIS) been reported? A. There is at least one invasive plant reported or present at Canandaigua Lake. Invasive species reported in the lake include Eurasian Watermilfoil, Curly Leafed Pondweed, and Water Chestnut. Fishhook Waterflea, Chinese Mystery Snail, Asian Clam, Common Carp, Quagga Mussel, Zebra Mussel, and Scud have been reported in Canandaigua Lake. Canandaigua Lake has high vulnerability for new invasives, based on calcium levels.

How to Read the Report This guide provides a description of the CSLAP report by section and a glossary. The sampling site is

indicated in the header for lakes with more than one routine sampling site.

Physical Characteristics influence lake quality:

• Surface area is the lake’s surface in acres and hectares.

• Max depth is the water depth measured at the deepest part of the lake in feet and meters.

• Mean depth is either known from lake bathymetry or is 0.46 of the maximum depth.

• Retention time is the time it takes for water to pass through a lake in years. This indicates

the influence of the watershed on lake conditions.

• Lake classification describes the “best uses” for this lake. Class AA, AAspec, and A lakes may

be used as sources of potable water. Class B lakes are suitable for contact recreational

activities, like swimming. Class C lakes are suitable for non-contact recreational activities,

including fishing, although they may still support swimming. The addition of a T or TS to any

of these classes indicates the ability of a lake to support trout populations and/or trout

spawning.

• Dam classification defines the hazard class of a dam. Class A, B, C, and D dams are defined as

low, intermediate, high, or negligible/no hazard dams in that order. “0” indicates that no

class has been assigned to a particular dam, or that no dam exists.

Watershed characteristics influence lake water quality:

• Watershed area in acres and hectares

• Land use data come from the most recent (2011) US Geological Survey National Land Use

Cover dataset

CSLAP Participation lists the sampling years and the current year volunteers.

Key lake status indicators summarize lake conditions:

• Trophic state of a lake refers to its nutrient loading and productivity, measured by

phosphorus, algae, and clarity. An oligotrophic lake has low nutrient and algae levels (low

productivity) and high clarity while a eutrophic lake has high nutrient and algae levels (high

productivity) and low clarity. Mesotrophic lakes fall in the middle.

• Harmful algal bloom susceptibility summarizes the available historical HAB data and indicates

the potential for future HAB events.

• Invasive vulnerability indicates whether aquatic invasive species are found in this lake or in

nearby lakes, indicating the potential for further introductions.

• Priority waterbody list (PWL) assessment is based on the assessment of use categories and

summarized as fully supported, threatened, stressed, impaired, or precluded. Aesthetics and

habitat are evaluated as good, fair, or poor. The cited PWL assessment reflects the “worst”

assessment for the lake.

Current year sampling results

• Results for each of the sampling sessions in the year are in tabular form. The seasonal change graphically shows the current year results. Red shading indicates eutrophic readings.

• HAB notification periods on the DEC website http://www.dec.ny.gov/chemical/83310.html

• Shoreline HAB sample dates and results. Samples are collected from the area that appears to have the worst bloom. Red shading indicates a confirmed HAB.

• HAB sample algae analysis. Algae types typically change during the season. These charts show the amount of the different types of algae found in each mid-lake or shoreline sample. Samples with high levels of BGA are HABs. The second set of charts show the level of toxins found in open water and shoreline samples compared to the World Health Organization (WHO) guidelines.

• If there are more than ten shoreline bloom samples collected in a year, bloom sample information is instead summarized by month (May-Oct.) as minimum, average, and maximum values for blue-green algae and microcystin.

Long-Term Trend Analysis puts the current year findings in context. Summer averages (mid-June

thru mid-September) for each of the CSLAP years show trends in key water quality indicators. The

graphs include relevant criteria (trophic categories, water quality standards, etc.) and boundaries

separating these criteria.

In-Season Analysis shows water temperature and water clarity during the sampling season. These

indicate seasonal changes and show the sample year results compared to the typical historical

readings for those dates.

format, comparing information from the current year and historical average of the CSLAP data.

Indicators include (1) trophic status of phosphorus, chlorophyll (or algae) and secchi (or clarity); (2)

presence or absence of aquatic invasive plants or animals; (3) lake user perception based on

perceived physical condition and recreational suitability of the lake; (4) harmful algal bloom samples

or reports; and (5) algae levels in the open water of routinely sampled sites.

The Lake Summary reviews and encapsulates the data in the lake report, including comparisons to

historical data from this lake, and results from nearby lakes.

Glossary of Water Quality and HAB Indicators

Clarity (m): The depth to which a Secchi disk lowered into the water is visible, measured in meters.

Water clarity is one of the trophic indicators for each lake.

TP (mg/L): Total phosphorus, measured in milligrams per liter at the lake surface (1.5 meters below

the surface). TP includes all dissolved and particulate forms of phosphorus.

Deep TP: Total phosphorus measured in milligrams per liter at depth (1-2 meters above the lake

bottom at the deepest part of the lake or a fixed depth in the hypolimnion of very deep lakes).

TN: Total nitrogen, measured in milligrams per liter at the lake surface. TN includes all forms of

nitrogen, including NOx (nitrite and nitrate) and NH4 (ammonia).

N:P Ratio: The ratio of total nitrogen to total phosphorus, unitless (mass ratio). This ratio helps

determine if a lake is phosphorous or nitrogen limited.

Chl.a (µg/L): Chlorophyll a, measured in micrograms per liter. Indicates the amount of algae in the

water column. This is an extracted chlorophyll measurement.

pH: A range from 0 to 14, with 0 being the most acidic and 14 being the most basic or alkaline. A

healthy lake generally ranges between 6.5 and 8.5.

Cond (µmho/cm): Specific conductance is a measure of the conductivity of water. A higher value

indicates the presence of more dissolved ions. High ion concentrations (> 250) usually indicate

hardwater, and low readings (< 125) usually show softwater.

Calcium (mg/L): Calcium, a component of lake buffering capacity (the ability to neutralize acid

inputs), as measured in milligrams per liter at the lake surface (1.5 meters below the surface).

Chloride (mg/L): Chloride, or chloride ions, as measured in milligrams per liter at the lake surface

(1.5 meters below the surface).

Upper Temp (°C): Surface temperature, measured in degrees Celsius.

Deep Temp (°C): Deep water temperature, measured in degrees Celsius.

BG Chl.a (µg/L): Chlorophyll a from blue-green algae, measured in micrograms per liter. This is an

“unextracted” estimate using a fluoroprobe. This result is different from the extracted chlorophyll

measurement described above.

HABs: Harmful Algal Blooms. Algal blooms that have the appearance of cyanobacteria (BGA).

BGA: Blue-green algae, also known as cyanobacteria.

Microcystin (µg/L): The most common HAB liver toxin; total microcystin above 20 micrograms per

liter indicates a “high toxin” bloom. However, ALL BGA blooms pose a potential health risk and

should be avoided.

PROPOSAL FOR THE GORHAM EXPANSION, NY

The TrojanUVSwift™ is currently being used to treat over 2 billion gallons a day in municipal drinking water plants around the world. With over 500 installed reactors, the TrojanUVSwift™ has demonstrated

its proven, validated solutions for disinfection and taste & odor treatment.

Gorham Expansion, NY - 2 -

We are pleased to provide the following TrojanUVSwift™ proposal for the Gorham Expansion, NY project.

The TrojanUVSwiftTM is well suited to meet current and upcoming regulations to protect the public from various pathogens including the chlorine-resistant Cryptosporidium and Giardia. The system uses high-intensity, medium- pressure lamps to minimize footprint and headloss. The ActiClean™ cleaning system meets NSF 60/61 compliance and eliminates routine quartz cleaning. All Trojan installations are supported by a global network of certified Service Representatives, providing local service and support.

The TrojanUVSwiftTM system can be initially designed to enable a simple and cost-effective upgrade in the future to a UV-oxidation system for the treatment of chemical contaminants. In addition to disinfection, the UV-oxidation process can be used for taste and odor treatment as well as the destruction of pesticides, volatile organic compounds, and pharmaceuticals/personal care products. Contact your Trojan Representative for more information.

Please do not hesitate to call us if you have any questions regarding this proposal. Thank you for the opportunity to quote the TrojanUVSwift™ and we look forward to working with you on this project.

With best regards,

John Faber 3020 Gore Road London, Ontario N5V 4T7 (519) 457-3400 ext. 2389 [email protected]

Gregg Palmer Koester Associates, Inc. C/O MRB Greg Hotaling P.E.

Dear Greg,

Trojan Technologies is pleased to submit this cost estimate for the supply of a TrojanUVSwift™ECT UV-Oxidation treatment system for the Gorham Water Treatment Plant in New York. Our current understanding is that the TrojanUVSwift™ECT system will be used to provide disinfection and Algal Toxin treatment. For the purposes of sizing the UV system, 1.0 log reduction of microcystin LR (MCLR) is the contaminant targeted for removal.

Because more UV light is required for cyanobacteria treatment than disinfection, during algal bloom events disinfection is simultaneously achieved. During these events, the system operates in “MCLR Control + Disinfection Mode.” This mode requires that the system deliver more UV energy into the water (by increasing lamp power) and requires the dosing of hydrogen peroxide (H2O2). UV in combination with H2O2 is a process known as UV- oxidation. UV- oxidation also destroys a wide variety of pesticides, industrial contaminants, pharmaceuticals, and endocrine disrupting chemicals. When no requirement for UV oxidation treatment exists, the UV system can be operated in “Disinfection-Only Mode.” During Disinfection-Only Mode, H2O2 is not dosed and the lamp power is turned down to levels sufficient for disinfection.

The TrojanUVSwift™ECT UV-oxidation system will cost-effectively treat MCLR present in the water. The recommended Trojan UV-oxidation equipment, hydrogen peroxide concentrations, and capital equipment price are listed below.

As with all UV-oxidation projects, this estimate is conditional upon the receipt of a water sample by Trojan for testing to verify UV system sizing. The sizing provided is based on propriety sizing models developed by Trojan and may not be shared or made public without Trojan’s consent.

DESIGN CRITERIA

Peak Design Flow: 2 MGD (expandable)

UV Transmittance: 97% (Estimated background scavenging demand)

Target Contaminant Removal 1.0 log Microcystin LR (MCLR)

Disinfection Treatment 40 mj/cm2 (higher dose available)

Hydrogen Peroxide Dose 3.0 ppm (residual 2.5ppm)

Proposed TrojanUVSwift™ECT System Description

The proposed UV-Oxidation System consists of one (1) train of one (1) TrojanUVSwift™ECT Model 8L24 (for disinfection, redundancy will be required) reactor for MCLR removal. During disinfection-only mode, one train of one reactor is operated (running in 2 lamp mode at reduced power levels). During algal bloom events all lamps would be utilized and the H2O2 dosing pump would begin dosing at the prescribed amount in order to maintain the required UV-Oxidation treatment level.

Total Capital Cost: $325,000 (USD)

Total Capital Cost: $95,000 (USD)

The pressurized UV system consists of stainless steel reactor chambers, lamps, appropriate flanges, and associated power distribution and control systems. Trojan’s chemical-mechanical quartz sleeve wiping system, Acticlean™ is standard equipment on the TrojanUVSwift™ECT. The H2O2 dosing and storage system consists of a primary metering pump skid, interconnecting piping, remote monitoring equipment and a 1,100 gallon double- contained HDPE storage tank. H2O2 is injected upstream of the UV reactors and is only injected when treating MCLR. The H2O2 delivery system and the UV reactors are integrated through control system algorithms. Trojan can provide 50% drinking water-grade H2O2 delivered to the site. A device, such as a static mixer (not provided by Trojan), may be required to achieve uniform distribution of the H2O2 in the water stream. All equipment has a one-year manufacturer’s equipment warranty.

This Trojan UV-oxidation package also includes Trojan’s sophisticated automatic Master Control system. Trojan has implemented a patent-pending Programmable Logic Controller (PLC) based control system that automatically optimizes UV lamp operation and dosing of hydrogen peroxide (H2O2) in such a way as to minimize ongoing operation and maintenance costs. This algorithm resides within the PLC and uses several online measurements to set the optimum ballast power and hydrogen peroxide levels that provide the required treatment level at the minimum operating cost. This control system ensures that the system is as operator-friendly and easy to use as possible.

As part of the TrojanUVSwift ECT™ UV-oxidation system offering, Trojan is able to provide ongoing supply, service support and application optimization of H2O2 . This includes remote monitoring through the ChemWatch™ system, automatically scheduled deliveries, automatic invoicing, remote diagnostics, and all handling of H2O2 (plant operators never need to come in direct contact with H2O2). The package can be continued simply by purchasing H2O2 from Trojan. Due to the large volume of H2O2 delivered through Trojan, H2O2 can be provided at the lowest market prices.

About Trojan UV-Oxidation

UV-oxidation is a photochemical process that breaks down chemical constituents into their non-odorous component parts. Trojan has revolutionized UV-oxidation, making it an efficient and cost-effective approach to treating and destroying many T&O-causing compounds.

Trojan UV-oxidation involves the addition of H2O2 to the influent, and a photochemical reaction that occurs almost instantly within the UV reactor. UV light incident on H2O2 breaks H2O2 (through the UV- photolysis reaction illustrated at right) into two hydroxyl radicals. These highly reactive radicals destroy MIB and geosmin.

Benefits of Trojan UV-Oxidation

• Elimination of your taste and odor problem

• Disinfection in accordance with LT2 at no additional capital cost (i.e. 2-log crypto credit)

• The process does not form potentially hazardous by-products such as bromate

• Capital and O&M costs are both lower for the TrojanUVSwift™ECT Solution relative to ozone

• The footprint is very small relative to ozone and other technologies. This results in a simpler installation with a significantly reduced building capital cost

• Flexibility: if no T&O event, the system remains in disinfection-only mode and therefore annual O&M costs are in the range of 1 cent/1,000 gallons

• It can be easily retrofitted into existing plants • It is safer than ozone

The TrojanUVSwift™ECT

The TrojanUVSwift™ECT employs H2O2 and sophisticated controls to optimize the treatment of environmental contaminants. The broad light spectrum of light emitted by the medium pressure lamps in the TrojanUVSwift™ECT makes it extremely well suited for the treatment of many contaminants, particularly some pesticides and taste and odor-causing compounds found in surface waters. Its ultra-compact footprint, its ability to apply large amounts of UV light, and high flow capacity make it an excellent reactor for use as part of a multi- barrier system in large municipal applications.

Key Benefits of the TrojanUVSwift™ECT:

TrojanUVSwift™ECT is: • The most compact UV reactor available • Capable of treating hundreds of millions of gallons per day • Available in a variety of power capacities (i.e. number of lamps) • Designed for hydraulic efficiency using computational fluid dynamics • All wetted surfaces constructed of NSF-listed materials • Integrated (via control algorithms) with the H2O2 delivery system

• Equipped with a control algorithm to minimize electrical consumption by dimming lamps while still maintaining performance

• Available with Acticlean™, a chemical/mechanical wiper mechanism for maximization of quartz sleeve transmittance

EQUIPMENT WARRANTEES

1. Trojan Technologies warrants all components of the system (excluding UV lamps) against faulty workmanship and materials for a period of 12 months from date of start-up or 18 months after shipment, which ever comes first.

2. UV lamps purchased are warranted for 9,000 hours of operation or 3 years from shipment, whichever comes first. The warranty is pro-rated after 1,000 hours of operation. This means that if a lamp fails prior to 1,000 hours of use, a new lamp is provided at no charge.

3. Electronic ballasts are warranted for 10 years, pro-rated after 1 year.

FEATURES & BENEFITS

Lifetime Performance Guarantee Trojan offers an unparalleled Lifetime Performance Guarantee. The spirit of this guarantee is simple: the Trojan equipment, as sized for the project, will meet the disinfection requirements for the life of the system.

Validation The TrojanUVSwift™ is fully validated at a wide range of flow rates and UV transmittance levels in full compliance with the protocols of the USEPA UV Guidance Manual.

Multiple Barrier Treatment Approach UV offers an additional barrier of protection to safeguarding drinking water against virtually all microorganisms treated by chlorine – as well as proven inactivation of chlorine-resistant protozoa, including Cryptosporidium and Giardia.

Upgradability from Disinfection-only System If you choose to forego UV Oxidation for a disinfection system at this point in time, you may wish to explore the low-cost way of preparing to upgrade to UV Oxidation system for future treatment requirements. Ask your TrojanUV representative about this option.

Clarifications and Exceptions General Clarifications Terms & Conditions: This proposal, including all terms and conditions contained herein, shall become part of any resulting contract or purchase order. Changes to any terms and conditions, including but not limited to submittal and shipment days, payment terms, and escalation clause shall be negotiated at order placement, otherwise the proposal terms and conditions contained herein shall apply.

Paint: If your equipment has paint included in the price, please take note to the following. Primer paints are designed to provide only a minimal protection from the time of application (usually for a period not to exceed 30 days). Therefore, it is imperative that the finish coat be applied within 30 days of shipment on all shop primed surfaces. Without the protection of the final coatings, primer degradation may occur after this period, which in turn may require renewed surface preparation and coating. If it is impractical or impossible to coat primed surfaces within the suggested time frame, WesTech strongly recommends the supply of bare metal, with surface preparation and coating performed in the field. All field surface preparation, field paint, touch-up, and repair to shop painted surfaces are not by WesTech.

Escalation: If during the performance of the contract, the price of labor, material, freight, and other costs significantly increase, through no fault of WesTech, the price shall be equitably adjusted and subject to escalation. A significant price increase shall mean any price increase from proposal date to material procurement greater than 2.5% from stated prices. Delays and costs associated with a Force Majeure event shall also be equitably adjusted and subject to a change in price and/or schedule. Escalation to be based on cost increases, (without additional profit, overhead or margin) and shall include labor, material, freight, and other costs to WesTech that occur in the specified time period. Any revisions or changes requested by the customer will be priced on a case-by-case basis. Such price increases shall be documented through third party sources. Carbon material escalation will be based on the US Midwest Domestic Index, current flats and longs indexes, in effect at the time of bid. Stainless material escalation will be based the Argus Metals Stainless Steel ex works US base price plus surcharge for flat and bar (per design specified alloy), in effect at the time of bid.

USA Tariffs and Current Trade Laws: All prices are based on current USA and North America tariffs and trade laws/agreements at time of bid. Any changes in costs due to USA Tariffs and trade laws/ agreements will be passed through to the purchaser at cost.

Trident Clarifications • Due to the current market volatility with material cost, the budget price should be updated

routinely or when there are changes in the scope of supply. Note the budget price is only valid for 30 days from dated of budget proposal.

• The Trident system design is for an N+1 redundancy condition to treat 1.5 MGD. • Tank is designed for installation on coal tar or asphaltic type base mastic compound applied to

concrete base pad by others. • The filter is periodically backwashed (using treated water). The Adsorption Clarifier is normally

washed (using influent water) one or more times between filter backwashes. The waste holding system should be sized to handle a total of two complete flush/wash volumes from each compartment.

Proposal: 2030312_Rev11 15

• The influent pumping system should provide a range of 20–30 feet head at tank inlet connection. The high-rate water only backwash of the filter shall be 15–18 gpm/ft2 with an available head of 13 feet at the tank connection.

• A 50 percent duty cycle is recommended for the compressed air system. • Availability of equipment components specified may dictate substitutions of equal quality at the

discretion of WesTech. • All hardware is crated and shipped to the jobsite for assembly by the contractor.

Items Not Furnished by WesTech • Unloading of equipment from delivering carrier, protected storage of equipment • Installation of equipment, supervision of installation • All underground and interconnecting piping, filter face piping and fittings, pipe supports, wall

High�Density�Crosslinked�Polyethylene

High-density crosslinked polyethylene, or XLPE, is a thermoset resin that is specifi cally designed for critical applications like chemical storage. During the XLPE manufacturing process, a catalyst (peroxide) is built into the resin, which creates a free radical. The free radical generates the crosslinking of the polymer chain, so the tank essentially becomes one giant molecule. The result is a resin that is specifi cally designed for critical chemical applications.

XLPE versus Linear Polyethylene

• XLPE has 20 times the environmental stress crack resistance of HDPE.• It has 10 times the molecular weight of HDPE.• It has 5 times the impact and tensile strength of HDPE.

XLPE versus Fiberglass-Reinforced Plastic (FRP)

• XLPE off ers seamless construction for greater strength.• With FRP, chemicals can wick into the fi ber, compromising tank life.• XLPE can have a lower cost of ownership, due to the low amount of required maintenance compared to FRP.• FRP o� en requires special handling to avoid cracking.

XLPE versus Carbon and Stainless Steel

• XLPE has seamless one-piece construction, which eliminates the potential for chemical a� ack points and bad welds.

• Unlike carbon and stainless steel, XLPE has very broad chemical resistance capabilities without the need for high-cost coatings.

• XLPE does not require ongoing maintenance and inspection.• XLPE is a cost-eff ective solution to high-priced alloys.

Design Information

Water Quality

WesTech UF/MF systems will consistently produce high purity treated water even with variation in the feed source due to a small nominal pore size in an absolute barrier configuration.

Feed Water Quality* Description Unit Concentration Source - Surface Water pH - 6.5 – 8.5 Temperature °C 5 – 20 Turbidity NTU < 25 Total Suspended Solids mg/L < 5 Total Organic Carbon mg/L < 3 Iron mg/L < 0.3 Manganese mg/L < 0.05

*Values are assumed and should be verified. It is noted that the use of charged polymeric flocculant aids increases risk of irreversible membrane fouling and should be discussed with WesTech, and this risk is applicable to all polymeric MF/UF membrane manufacturers. The presence of oil and grease in the source water should also be minimized.

Treated Water Quality Description Unit Concentration Turbidity NTU ≤ 0.10, 95% of the time

≤ 0.3 maximum Total Suspended Solids mg/L < 1 Silt Density Index - ≤ 3 Giardia Removal* - ≥ 4 log (99.99%) Cryptosporidium Removal* - ≥ 4 log (99.99%) Virus Removal* - ≥ 1.0 log removal (90.00%) Certification Standards NSF/ANSI 61, NSF/ANSI 419, UL 508A Listed

*Challenge-testing certification is provided by independent evaluation through NSF/ANSI 419. Typical removal levels exceed the certification level and are often on the order of 6-log. Additionally, the UF membranes achieve 1.5 log removals of viruses, though virus removal certification is only recognized up to 1.0 log by CDDW for any membrane filter.

Proposal: 2030312_Rev12 5

Process Description

Described in this proposal is the preliminary process and design of the WesTech membrane filtration system for the Gorham WTP project. The preliminary system design consists of three (3) membrane filtration units sized to achieve a net production capacity of 1.5 MGD with one unit offline. Accordingly, the system is designed with N+1 redundancy. Each unit has capacity for up to 34 modules, with 32 installed.

The filtration process is an outside/in, pressure-driven process to remove suspended solids and turbidity, and to achieve 4-log reduction of pathogens like Giardia and Cryptosporidium. Ultrafiltration membranes can also achieve >1.5 log reduction of waterborne viruses. Raw water from the water source is transferred to the feed tank. VFD-controlled feed pumps direct the source water to a 200 µm pre-filter for removal of larger debris. The feed pump controls will be configured to minimize flow variation between steps and instantaneous flux by operation of the maximum number of available units.

Filtrate is sent to the backwash supply tank (by others). Backwashing is used to remove accumulated foulants by reversed inside/out flow at an interval of 20 - 60 minutes with air scour for increased agitation. A drain or filter-to-waste step is used to remove any additional accumulated material. Membrane integrity testing is conducted automatically once every 24 hours. The pressure decay test (PDT) is capable of detecting a single fiber break.

Maintenance cleans (MCs)/chemically-enhanced backwashes (CEBs) and clean-in-place (CIP) procedures are automated chemical cleaning processes used to recover membrane permeability. MCs/CEBs are typically performed with NaOCl biweekly. The automated clean-in-place procedure is designed to occur no more frequently than once per month, is conducted with either NaOCl or acid, and is initiated when membrane permeability decreases to a specified value.

Following chemical cleaning procedures, the membrane units are drained by gravity or a pressurized drain-to-waste, and waste is subsequently sent to the discharge location. A rinse step and backwashing are used to remove residual chemical prior to resuming production. If desired, chemical cleaning waste can be captured and neutralized prior to discharge.

Labor Estimate

The ultrafiltration system is programmed for automatic operation, but operator involvement is required to make system adjustments, monitor performance, and perform routine maintenance. It is requested that the operator complete a basic operating log. While many of these parameters are automatically logged by the system, it is beneficial for the operator to directly observe and understand these parameters on a regular basis to ensure proper operation. A basic outline of the operator time requirements to operate the ultrafiltration system is as follows.

• 1 hour per day to perform a daily check and complete daily operating logs • 4 hours per week to measure data in operating logs and to perform routine maintenance • 8 hours per month per skid to monitor clean-in-place procedures • Additional labor as required for maintenance

Maintenance and Parts

Components are selected by WesTech for their durability and reliability. The majority of components are not expected to require replacement in the first 10 years of operation. An example of parts that are recommended to be replaced and maintained are as follows:

• pH Electrode: Replace every 1-2 years • Compressor Oil and Oil Filter: Replace every year or every 2,000 hours operation • Compressor Air Filter and Oil Separator: Replace every year or every 4,000 hours operation • Butterfly Valves: Inspect and replace valve seat when necessary

ELECTRICAL AND MECHANICAL EVALUATION

(JADESTONE ENGINEERING)

Jade Stone Engineering, PLLC

1 Water Treatment Plant Evaluation Town of Gorham

Electrical Evaluation:

Electrical Service and Distribution Equipment:

The Water Treatment Plant (WTP) is served by an overhead 200 AMP, 480/277 volt, three phase, 4-wire electrical service. The electrical service originates from three utility pole-top transformers (NYSEG owned) located adjacent to the site. From utility pole-top transformers the electrical service enters the building overhead through a weather head with a 2” conduit down to the meter. The service entrance feeder terminates within a heavy-duty safety switch located on the exterior of the WTP. The utility owned metering equipment (meter, etc.) is located on an exterior wall of the WTP so that it is accessible to the utility company on an as needed basis. Once thru the main service disconnecting means, power is routed thru a 200-amp, ASCO, Automatic Transfer Switch (ATS), and then distributed throughout the building/site to various distribution panelboards, transformers, and devices/equipment.

The electrical distribution system is made up of a main service disconnect switch (MDS), an automatic transfer switch (ATS), distribution panelboard, process control panels, several dry-type transformers, several panelboards, and several equipment disconnects across the site. The distribution equipment is of various sizes, ratings, and manufacturers. That said, most equipment is as manufactured by Square D. It was observed that most distribution equipment appears original to the facility with the exception of the service entrance cable and a panelboard which were replaced within the last 15 years. Original construction is from the late-1960s. Cursory observations indicate that original electrical distribution equipment has not had industry accepted preventative maintenance which would provide a better understanding of the internal working condition. The overcurrent protective devices (circuit breakers & fuses) within the distribution equipment that is original to the 1960s is using outdated technology, and thus have slow clearing/trip times in the event of a fault/problem (in comparison to modern equipment). As a result of slow clearing/trip times the equipment has the potential to build energy and cause a significant arc flash event which can be extremely dangerous. Facility personnel noted nuisance circuit breaker tripping has been an issue.

Equipment that dates to the 1960s has reached the end of its useful life and is now considered obsolete. Note, typical useful life of distribution equipment like that installed around the WTP is 30 years. With replacement parts for the existing distribution equipment becoming increasingly difficult to locate, facility downtime could become a significant factor in the event of an equipment failure. Operators noted it being a challenge to find replacement circuit breakers.

An additional observation regarding the distribution equipment is that we observed some panelboards and motor control centers which were primarily full of branch breakers and buckets with little to no space for future additions.

Most existing interior conduit systems where visible and able to be inspected, appeared to be in satisfactory condition. Existing conduit systems (where in satisfactory condition) in the event of a capital improvements project have the potential to be reutilized where practical/feasible.

Emergency Generator System:

Jade Stone Engineering, PLLC

2 Water Treatment Plant Evaluation Town of Gorham

The WTP has one (1) existing emergency generator system (EGS). The EGS is natural gas fuel fired and is manufactured by Generac. The EGS is rated 25kW and housed in an outdoor enclosure. The EGS appears to be installed in 2011. The EGS system provides emergency power to select loads throughout the facility given a normal power failure. The transfer of power from normal to emergency power is accomplished by automatic means by use of an automatic transfer switch. The engine generator system is currently the only permanent means of emergency power for the WTP’s critical operations and systems given a normal power failure. Emergency power is only provided to select loads and not the entire WTP. Per conversations with facility personnel, it was noted that there is also a trailer mounted 127kW generator available that is capable of running the entire facility. The trailer mounted generator can be used through means of a double throw safety switch which allows selection of either the 25kW generator (mentioned above) or the trailer mounted generator (when connected).

Lighting Systems – General Lighting, Emergency Lighting, & Exit Signage:

Most of all interior and exterior lighting systems consist of LED fixtures. Most of the existing lighting control was observed to be by means of manual switching (no automatic control observed), which is not in compliance with the current New York State Energy Code. It was noted while on site that the exterior lighting is accomplished by means of exterior building mounted wall-pack lighting fixtures. The lights were all recently upgraded to LED.

Egress emergency lighting was not observed to follow current code requirements. It was also noted that exist signage needed a replacement along with the need for additional signs to follow current codes/standards.

Variable Frequency Drive Discussion:

Upon preliminary review, the only motors observed to utilize a variable frequency drive (VFD) for motor starting/control were the two (2) 50HP high lift pumps. All other major motors at the WTP appear to not have an associated VFD, but rather use an across the line style motor starter. The two (2) VFDs that were observed were installed in 2017. These VFDs appear in good working condition. It was noted that the VFDs do not appear to have bypass capability which would provide additional flexibility by allowing the motors to be started across the line and continue to be operational in the event there is an issue/failure with the VFD itself.

NEC Required Working Clearance:

There were instances around the WTP in which current NEC required working clearances were not adequate. Clearances are to provide protection to workers, access to the equipment, and protection of the equipment from nonelectric equipment. For example, per code dedicated working space is required from the floor to a height of 6’-6” and extend 3’-0” in front of a typical panelboard. No other objects are to be within this dedicated working space. We noted that in front of the panelboards and disconnects in the WTP there were stored items within the dedicated working space.

Jade Stone Engineering, PLLC

3 Water Treatment Plant Evaluation Town of Gorham

Exposed Equipment/Devices/Wiring:

It was observed that there are instances in which existing electrical equipment has missing covers and/or faceplates, exposing energized (live) electrical components. This creates an unsafe working environment.

Feeders/Branch Circuitry:

Existing electrical feeders and branch circuitry was not examined as part of the field survey as these items were not visible nor readily accessible without removing covers and panel doors. It is assumed that the majority or all electrical feeders and branch circuitry are original to the facility (date to the 1960s). It was noted during the site visit that the electrical service entrance feeder was recently replaced from the pole overhead to the facility.

New York State Energy Code Compliance:

The current New York State Energy Code requires spaces within administrative type areas to have automatic operation of lighting systems as a means of energy conservation. No automatic lighting controls were observed where required by code.

Power System Analysis:

Per NEC and NFPA, arc flash warning labels shall be applied to all electrical equipment likely to require examination, adjustment, servicing, or maintenance while energized. This may include, but is not limited to, motor control centers, panelboards, control panels, transfer switches, disconnects, controllers, etc. No arc flash labeling was observed during our field investigation at the WTP. In addition, service equipment shall clearly identify the maximum available fault current to properly verify equipment is sufficiently rated to withstand such a fault. The service equipment was observed to not be properly labeled.

Electrical Recommendations:

Electrical Service and Distribution Equipment:

As mentioned within the evaluation section above most electrical distribution equipment is original to the facility in which it is installed within, and dates to the late-1960s. This equipment has reached the end of its useful life and is now considered obsolete. Note, typical useful life of distribution equipment like that installed around the WTP is 30 years. With replacement parts for the existing distribution equipment becoming increasingly difficult to locate, facility downtime could become a significant factor in the event of an equipment failure.

For these reasons it is recommended that all original (late-1960s vintage) electrical distribution equipment such as the motor control center, panelboards, dry-type transformers, etc. be replaced with modern gear throughout the WTP. By replacing distribution equipment before it ultimately fails, staff will avoid the tedious process of seeking replacement parts for aging electrical equipment (a process with the potential for extended downtimes). Where installed, all new equipment to be by a single manufacturer for ease of operation and maintenance. As part of these replacements, the existing overcurrent protective devices (circuit breakers & fuses) will be replaced with new, which consist of modern technologies (electronic trip units) greatly reducing clearing/trip times and creating a much safer environment for personnel who come into contact and work around the distribution equipment (in comparison to current conditions). All new equipment to be rated and suitable for use with the electrical service. All new equipment to be rated and suitable for use with the existing electrical service.

Preliminary loading calculations were developed to verify existing electrical service size. An electrical service can be loaded to 80% its listed rating, thus the existing 200-amp service can safely support 160 amps worth of electrical load. The service calculation was developed using utility demand data for 2020. Utility data reviewed ranged from December 2019 through December 2020. Results of reviewing previous utility data showed that the peak demand over the range of dates was 95.6 kW within the month of July 2020. This equates to roughly 142.5 amps (built in 1.25% safety factor) of electrical load on the existing service. This indicates the electrical service is approaching its upper limits/capacity with little room for additional load.

During the final design phase an additional approach/calculation will be used to verify the capacity of the existing electrical service. This approach will involve creating an inventory of major motor loads and factoring load diversity such as operational procedures into the calculation. Although using previous utility demand information suggest that the electrical service is at maximum capacity, we want to ensure this is accurate given worst case operational scenarios that might not have been experienced over the course of 2020. Further evaluation and analysis required during the final design phase, but it is more than likely that a larger electrical service will be required if additional load (UV Disinfection System) is to be added to the facility.

The incoming electrical service conductors will be evaluated during the final design phase to ensure they have adequate capacity to carry the load of the WTP as outlined above. It is anticipated that the existing service conductors have a 200-amp capacity.

Jade Stone Engineering, PLLC

5 Water Treatment Plant Evaluation Town of Gorham

During a cursory review it was noted that the existing utility transformers where the electrical service is derived from is comprised of three (3) pole-mounted transformers. As it is anticipated that additional electrical load will be added to the WTP, updated loading information will be required to be submitted to the utility (NYSEG) to ensure proper utility transformer sizing. Utility coordination to occur during the final design phase.

Emergency Generator System (EGS):

Given the inadequate sizing and criticality of the existing emergency generator system (EGS) the existing system is recommended to be replaced with new. It is proposed that the replacement system be installed outdoor, in a weatherproof & sound attenuated enclosure. By installing a generator outdoors, numerous HVAC requirements and monitoring requirements can be avoided. Also, architectural, and structural modifications that might be necessary to achieve required clearances can be avoided. It is proposed that the replacement EGS be natural gas fuel fired.

As part of the recommended generator replacements, a new modern automatic transfer switch is recommended be installed with the new generator system to ensure complete system compatibility. The transfer switch is to be located at the beginning of the electrical distribution system. Note, with an ATS located at the front end of the electrical distribution system, the EGS will have the capability to power any electrical load associated with the WTP, it is simply a question of whether the generator has the capacity to do so. This provides the WTP staff additional flexibility when under emergency power situations. The ATS is to be utilized to transition to generator power automatically given a normal power failure.

During the final design phase emergency generator system sizing calculations will be performed for the proposed generator system to determine a size of the EGS with the capability of powering all critical loads. Close coordination with the WTP staff required to identify all emergency power requirements. The critical loads will be staged into different steps, assuming a slight time delay between each step to prevent large in-rush currents. This allows the generator systems to bring loads online at different times and recover engine capacity before starting the next critical load. Critical loads will be coordinated during final design.

The following parameters will be utilized when performing generator sizing calculations.

1. 480V, 3 phase, 60 Hertz

2. 125°C temperature rise

3. Class H insulation

4. 20 percent max allowable voltage dip

5. 10 percent max allowable frequency dip

6. Standby operation

7. PMG excitation

8. Outdoor generator set

9. Single engine generator set (no paralleling)

10. Load stepping

There would be a programmed time delay between the starting of each process/load. Utilizing multiple steps to load the generator prevents grossly oversizing an emergency generator by allowing the unit to recover after each loading step, separating out the load on the generator.

Based upon preliminary loading information, a new generator unit with ratings capable of handling the entire WTP (125kW) is anticipated, with a final size established upon coordinating critical loads. Final generator loading and parameters will be closely coordinated with the Town and facility personnel during final design.

Lighting (General Lighting, Emergency Lighting, & Exit Signage):

It is recommended that all interior fixtures be controlled by means of an occupancy sensor or vacancy switch where practical (administrative areas). All exterior lighting fixtures to be controlled via a programmable time switch for automatic control (on at sunset and off at sunrise). Inadequate illumination levels to be improved and corrected to current lighting standards. By utilizing improved controls, the WTP will experience a reduction in energy consumption and all facilities will meet/exceed current New York State Energy Code requirements.

It is also recommended that facility emergency lighting and exist signage be added/installed per current standard and codes throughout the WTP.

Variable Frequency Drive Discussion:

It is recommended to implement VFDs on any new process equipment with a significant motor size in lieu of across the line motor starters. VFDs allow motors to be brought up to speed gradually to reduce the amount of inrush current seen by the electrical distribution system (much less of a strain on the electrical distribution system) and to reduce harmonic transients. The VFDs will also allow for increased control flexibility, increased monitoring capability, increased efficiency, as well as allow for ease of integration within a future modern SCADA/Control system. Note, as part of implementing VFDs all new associated motors are to be of the inverter duty type and suitable for use with a VFD. Although this is not a National Electrical Code (NEC) requirement, it is good practice. New insulated-gate bipolar transistor (IGBT) types of VFDs will damage non-inverter duty rated motors due to their high harmonic content. The insulation inside a continuous duty rated motor is typically not suited for use on a VFD and the motor will likely fail at any given time due to high voltage peaks typically present on a VFD output feeder. An inverter duty rated motor provides increased longevity over a continuous duty rated motor when used with an associated VFD. For these reasons when VFDs are proposed it is suggested that the associated motors be of the inverter duty type.

Also note, VFDs with bypass capability provide additional flexibility by allowing the motors to be started across the line and continue to be operational in the event there is an issue/failure with the VFD itself.

Although a beneficial feature, this option adds substantial cost and size to the VFD enclosure. For these reasons it is not recommended to proceed with bypass capability on any new VFDs.

NEC Required Working Clearance:

All new electrical equipment installations to follow National Electric Code (NEC) required working clearance requirements. Where possible it is recommended that all existing National Electric Code (NEC) required working clearance violations be corrected.

Exposed Equipment/Devices/Wiring:

It is recommended that all existing electrical equipment, devices, boxes, or conduit systems with a missing or damaged cover/faceplate have one provided to eliminate the exposure of energized electrical components, creating a safer working environment for WTP personnel.

Feeders/Branch Circuitry:

It is recommended that new branch circuitry and electrical feeders be installed for all proposed process improvements. It is recommended to reuse electrical feeders to distribution equipment where feasible and practical. The underground distribution system is anticipated to be re-used to the greatest extent possible. Conduit material to vary by space. For example, in damp unconditioned spaces rigid galvanized conduit should be utilized, in finished and conditioned spaces electrical metallic conduit can be utilized, and in corrosive/hazardous areas it is recommended that PVC coated rigid conduit be utilized. Any new required conductors to be copper and utilize THHN (interior) or XHHW (exterior/underground) insulation.

Exposed Equipment/Devices/Wiring:

It is recommended that all existing electrical equipment, devices, boxes, or conduit systems with a missing or damaged cover/faceplate have one provided to eliminate the exposure of energized electrical components, creating a safer working environment for WTP personnel. It is also recommended that any junction boxes that have deteriorated or rotted out be replaced.

Motor Disconnects:

Motor disconnect switches to be implemented on all new equipment per current NEC requirements. In addition, all newly installed disconnect switches to comply with height restrictions outlined within the NEC to ensure the operating handle is no higher than 6 feet 6 inches above finished floor/grade for ease of accessibility.

New York State Energy Code Compliance:

Jade Stone Engineering, PLLC

8 Water Treatment Plant Evaluation Town of Gorham

The use of vacancy sensors to automatically turn lights off after a programmed time delay is the most common practice to meet the New York State Energy Code requirements. It is recommended to implement these automatic controls where practical in the form of occupancy sensors, vacancy switches, and programmable time switches. Refer to the above lighting article for additional information.

Power System Analysis:

A power system study is to be completed as part of the construction phase per current NEC, NFPA, and OSHA codes/requirements for all electrical distribution equipment. As a result, arc flash warning labels will be applied to new electrical equipment that is likely to require examination, adjustment, servicing, or maintenance while energized. Labels to provide qualified individuals who intend to perform tasks on equipment during an energized state critical personal protective equipment (PPE) information and boundary information (limited approach, restricted, approach, etc.). The power study will identify proper PPE that is required for qualified individuals to perform work on existing energized gear.

Preventative Maintenance:

It is recommended that a preventative maintenance plan be implemented for all electrical distribution equipment upon project completion. A preventative maintenance plan will increase life expectancy of equipment as well as provide advance warning of potential failures. Final preventative maintenance and testing actions to follow the current ANSI standard for maintenance testing specifications of electrical power equipment and systems. Preventative maintenance to include but is not limited to the following: equipment cleaning, connections torqued down, inspections made, megger tests completed, current injection testing, thermal imaging, lubrication applied, etc.

Temporary Power:

The proposed improvements are anticipated to require minor temporary power provisions to maintain normal plant operation during the electrical distribution equipment modifications, generator replacement, and select process improvements. A few options will be investigated during final design to maintain normal operations during select electrical replacements. One option investigated will be to install replacement gear (where necessary) in a different location versus current locations, to get new equipment installed/connected while maintaining existing equipment online and a second option investigated will be to install replacement gear in the same location as existing. All options will likely require the need for temporary power stations, temporary cabling, and a temporary trailer mounted generator to facilitate continued operations. Temporary power provisions and a phasing plan will be established and investigated further during the final design phase.

Energy Efficiency:

It is recommended that improvements follow the high standards of energy efficiency. A couple items of note, all proposed significant motors (greater than 10HP) to be provided with associated variable

frequency drives where practical to conserve energy and help mitigate any potential peaks in electrical demand, which would result in increased electrical utility costs. It is also recommended as previously stated that all new lighting systems be of modern energy efficient LED technology with associated automatic controls to reduce energy consumption. Lastly all motors and HVAC equipment are to be of the energy efficient type to follow the trend of high efficiency equipment installed within WTPs of the 20th century.
