This project consisted of Phase II wastewater treatment plant improvements. The Village of Granville completed an upgrade to its wastewater treatment plant (WWTP) in September of 2005 and its purpose was to increase flow capacity and improve the removal of phosphorus and ammonia. In an effort to reduce the cost of the first plant upgrade, the New York State Department of Environmental Conservation (NYSDEC) permitted the Village to only construct a portion of the phosphorous removal upgrade which included two additional clarifiers and a chemical addition system. It had been determined that further WWTP improvements were necessary to comply with its State Pollutant Discharge Elimination System (SPDES) permitted phosphorous limitations.
The major components of the project included the following:
- Two (2) tertiary cloth disk effluent filters
- Improvements to building’s structure – new roof and insulation, new insulated walls, and mechanical appurtenances
- Modifications to existing grit removal system
- Emergency replacement of existing outfall structure in the Mettawee River
This project consisted of improvements to an existing 0.600 MGD activated sludge, tertiary treatment wastewater treatment facility to improve and rehabilitate existing unit processes.
The major components of the project included the following:
- 16,975 LF Collection System Sewer Replacement

- New 150′ x 75′ Reed Bed for Sludge Disposal (designed for up to 300,000 gal of sludge per year)
- New 18 kW Roof-mounted Photovoltaic Electrical System
- Miscellaneous Electrical Improvements, Including 200 KW Emergency Generator with Automatic Transfer Switch
- Storm Sewer Improvements incl. multiple pipe road culvert crossings
