Please refer to the general layout drawings of the water pollution control plant, at the conclusion of this section, depicting the existing facilities. The current permitted hydraulic capacity of the facility is 4,900,000 gallons per day and is an advanced wastewater treatment facility. The treatment plant is an aerobic biological treatment facility with grit removal, primary clarification, trickling filters, secondary clarification, nitrification towers, shallow bed sand filtration units, ultraviolet disinfection, sludge thickening, anaerobic biological sludge stabilization, sludge dewatering, thermally treated sewage sludge process, septage receiving station, and methane gas utilization facilities. PA 0025674 and is located on Meadowbrook Road in the Municipality of Murrysville. This facility is operated under National Pollutant Discharge Elimination System (NPDES) Permit No. This sewer system serves the Municipality of Murrysville, the Borough of Export, the Borough of Delmont, and portions of Salem Township, Penn Township, Municipality of Monroeville and Plum Borough. Wastewater from the well drilling and hydraulic fracturing (fracking) operations is not treated at our facility.The Franklin Township Municipal Sanitary Authority Sewage System comprises one (1) sewage treatment plant, fourteen (14) sewage pumping stations, collector sewers, conveyance sewers, five (5) regulators, and associated sewer appurtenances. Though these high flow rates exceed the plant's design capacity of 13.1 MGD, the plant still typically meet our mandated effluent limits.Īlong with wastewater from the municipal owners, the IAWWTF also treats peak weather flows diverted from the Cayuga Heights Wastewater Treatment Plant, and trucked wastes including: septage, landfill leachate, municipal sludge, alkaline hydrolysis waste, and airplane deicing fluid. This primarily results from: old sewers with cracks or leaky joints, illegally connected house footing drains, sump pumps, roof drains, and leaky manhole covers. This vast increase is due to the infiltration and inflow (I&I) of other water into the sewer. In addition, short term increases in volume, at times of rain fall and snow melt, can reach flow rates of 30 to 35 MGD. The plant treats approximately 6.5 million gallons per day (MGD) of raw sewage, although there are noticeable seasonal variations tied to school schedules. The IAWWTF is designed to remove nutrients, solids, and waterborne pathogens from the wastewater and to recycle clean water into Cayuga Lake. In addition, there are a small number of pump stations that help deliver wastewater to the IAWWTF for the treatment. Wastewater flows through the sanitary sewer mains primarily by gravity.

The service area has separate sanitary and stormwater collection systems.

There are approximately 80 miles of sanitary sewer mains located underground in the City of Ithaca, with many additional miles in the other areas served. The discharge permits for the IAWWTF can be found here.Īfter water is used in homes, institutions, and businesses, it is delivered as wastewater to the publicly owned sanitary sewer system. Several agencies are responsible for regulating different aspects of the operations at IAWWTF the New York State Department of Environmental Conservation (DEC), the Environmental Protection Agency (EPA), the New York State Department of Health (DOH), and the National Environmental Laboratory Program (NELAP). The Special Joint Committee (SJC), representing the three municipal partners, oversees operations, budget, and regulatory environment for the IAWWTF.Ĭayuga Lake is part of the Great Lakes Basin (Oswego-Seneca-Oneida Drainage Basin)> The Great Lakes Water Quality Initiative sets the effluent limits for the IAWWTF. Prior to 1987, the major portion of the wastewater plant was located in what is now the Sciencenter.
