  2. Problem Statement Current Waste Water Treatment Plant Condition Current Sanitary Sewer Costs Alternatives for Sewage Treatment and Disposal Estimated Cost of Alternatives Proposed Project Benefits of Proposed Project Project Plan Project Implementation Q & A Tonight’s Agenda

  3. Problem Statement • The existing Scottsville WWTP is at its limit of its permitted capacity largely because of excessive wet weather flow during spring months. • The existing process equipment is at the limit of its useful life. • Key treatment processes further limit actual plant capacity, especially grit removal and influent pumping. • Inefficient sludge disposal system. • Plant is subject to periodic flooding and/or hydraulic overloading.

  4. Current WWTP Condition • The Scottsville WWTP was constructed in 1968 (42 year old facility). • Much of the original equipment from 1968 is still in use and has reached the end of its intended design life. • The existing WWTP can only process 20% of sludge solids. The remaining 80% of sludge solids must be hauled from the WWTP, for disposal at the Monroe County Van Lare WWTP. • The WWTP has a permitted capacity for treatment of 0.65 Million Gallons per Day. During Spring months this permitted capacity is quite often exceeded. • The existing WWTP has virtually no excess capacity available to accommodate additional customers.

  14. Current Sanitary Sewer Costs Village of Scottsville Household The typical Village household sewer rate is currently $260 per year. • About $ 115 of this amount is for operation and maintenance of the Village sanitary sewer collection system. • About $ 145 of this amount is for operation and maintenance of the Village waste water treatment plant. • Currently the Village sanitary sewer operation is debt free.

  15. Current Sanitary Sewer Costs Town NE Sewer District Household The typical NESS household sewer rate is currently $183 per year. • About $38 of this amount is utilized by the Town for NESS collection system operation and maintenance. • About $145 of this amount is paid to the Village for sewage treatment and disposal.

  16. Current Sanitary Sewer Costs Village Household WWTP O&M $145 / year Sewer O&M $115 / year $260 / year • The difference in Village - $115/year and Town - $38/year sewer operation and maintenance costs is primarily due to differences between the two collection systems, especially age, pipe materials, and availability of storm sewers. • Town – Sewer Mains are 5 to 40 years old. • Village – Sewer Mains are 20 to 90 years old. Town NESS Household WWTP O&M $145 / year Sewer O&M $38 / year $183 / year

  17. Village Household Sanitary Sewer Rates Currently the Village sewer rate is $260. The graph shown below projects this sewer rate into the future at a 1.6% per year increase. In the past 20 years this rate has increased at an average of $6.00 per year.

  18. Monroe County Pure Waters Sewage Rates Currently the MCPW household sewage treatment rate is $81.40 per year. The graph shown below projects this household sewage treatment sewer rate into the future at a 1.6% per year increase. In the past 20 years this rate has increased at an average of $1.67 per year

  19. Village Household Sewer Rates – Pumping to MCPW By utilizing MCPW for sewage treatment, the Village household sewage treatment rate would be $81.40 per year. The sanitary sewer collection system household rate would be $115.32 per year. This represents an estimated yearly household treatment and collection system savings of $63.00. Current Village Sewer Rate of $260 per year

  20. Alternatives for Sewage Disposal • Complete Reconstruction of WWTP • Repair / Replace WWTP Equipment • Regional Pump Station & Force main to convey Sewage to Monroe County Pure Waters.

  21. Alternative 1 – WWTP Reconstruction • Complete Reconstruction of WWTP. • Estimated project cost is $7.0 Million. • Village must continue its commitment to Operate & Maintain WWTP. • Higher Household sewage treatment costs. • New larger plant may be subject to additional permit limits for nitrogen and phosphorus. • Will provide capacity to accommodate additional customers. • Continued discharge to Oatka Creek.

  22. Alternative 1 – WWTP Reconstruction Alternate3

  23. Alternative 2 – Repair/Replace WWTP Equip. • Repair / Replace WWTP Equipment. • Project cost is estimated at $1.7 Million initially. At 15 year intervals additional expenditures of $1.5 Million would be anticipated. • Service life is dependent on continued periodic expenditures to address future equipment and structural deficiencies. • Village must continue a commitment to the cycle of borrowing and debt repayment to keep an operational WWTP. • Village must continue its commitment to Operate & Maintain WWTP. • Higher sewage treatment costs. • Will not provide additional capacity. • Continued discharge to Oatka Creek • May be subject to more restrictive discharge limits in the future.

  24. Alternative 2 – Repair/Replace WWTP Equip. Alternate3

  25. Alternative 3 – Regional Pump Station • Construct a Regional Pump Station and Forcemain. • Estimated Project Cost is $4.5 Million. • Monroe County Pure Waters will operate & maintain the Pump Station & force main, and provide waste water treatment at VanLare. • Lower sewage treatment costs. • Eliminates potential future costs to the Village, once project debt service has been repaid. • System will provide additional capacity. • Eliminates WWTP discharge to Oatka Creek.

  30. Regional Pump Station & Forcemain Project Cost Estimate • Village is eligible for USDA Rural Development project funding. • Project funding will be accomplished through long term project financing. • Maximum Interest Rate of approximately 4% for a 38 year term.

  31. Regional Pump Station & Forcemain Project Benefits Lowest Yearly Cost • Represents a household cost increase of about $49 for the first year. • Lowest average yearly cost for 40 year service period. Operation and Maintenance • Village is no longer committed to WWTP Operation and Maintenance. • Monroe County Pure Waters will operate & maintain pump station system. • Lowest yearly Operation and Maintenance Cost. Environmental • Eliminates WWTP discharge to Oatka Creek. • Consolidates Waste Water Treatment to one Monroe County location. • Overland sludge hauling is eliminated. Service Life and Capacity • Long service life. • MCPW is responsible for future capital cost expenditures. • Will provide additional excess capacity.

  32. Regional Pump Station & Forcemain Project Plan • Construct a Regional Pump Station and Forcemain. • Pump Station to be located at existing WWTP site on River Road. • Pump station to be constructed to MCPW standards. • Forcemain will be a 17,000 feet long, 14-inch diameter pipe. • Forcemain will extend northward to NYS Route 253, then eastward along Route 253 to the Monroe County Interceptor Sewer located in Henrietta. • Project will address current problems with existing N.E. gravity trunk sewer located along the Greenway.

  33. Regional Pump Station & Forcemain Project Implementation Anticipated Schedule • Commence Construction in 2012 • Project Completion in 2013 Inter-Municipal Agreements (IMAs) Financing Requirements • Bond resolution • Final application to USDA Rural Development • Continue with other funding opportunities Easement Acquisitions Construction Impacts
