Elma T SD7 STP and Onsite Systems - Secondary Wastewater Treatment in Elma Center, New York

Elma T SD7 STP and Onsite Systems is a municipal wastewater treatment facility located in Elma Center, Erie County, New York. Serving a small population of 180, the plant provides secondary treatment to meet local water quality standards. The facility has a designed capacity of 75.71 m³/day and currently discharges 37.85 m³/day of treated effluent. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater. As a small facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation, ensuring compliance with effluent limits and monitoring requirements. The treated effluent from the plant is discharged into local waterways that ultimately drain into the Great Lakes basin, specifically Lake Erie. This region supports diverse aquatic life and is an important resource for recreation and drinking water. The plant's operations help protect downstream water quality in the Buffalo River watershed and Lake Erie.

The plant discharges into tributaries of the Buffalo River, which flows into Lake Erie, part of the Great Lakes system. Lake Erie is a vital freshwater resource supporting diverse aquatic ecosystems, including fish species such as walleye and perch. The watershed is ecologically sensitive due to historical nutrient pollution, and the plant's secondary treatment helps reduce the risk of eutrophication in the lake.
