Warsaw V STP - Wastewater Treatment Plant in Village of Warsaw, New York

Warsaw V STP is a municipal wastewater treatment facility located on Linwood Avenue in the Village of Warsaw, Wyoming County, New York. The plant serves a population of approximately 4,480 residents, classifying it as a small agglomeration under U.S. regulatory frameworks. Its inland location in western New York places it within the Great Lakes Basin watershed. As a U.S. facility, Warsaw V STP operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, administered by the New York State Department of Environmental Conservation. For small agglomerations like this, secondary treatment is typically required to meet effluent limits for biochemical oxygen demand and total suspended solids. The plant's treatment processes and capacity are designed to comply with state and federal standards for protecting local water quality. The plant discharges treated effluent into a receiving water body that ultimately drains into the Genesee River and then Lake Ontario, part of the Great Lakes system. This downstream environment supports diverse aquatic life and provides drinking water for millions. The facility plays a key role in preventing nutrient and pathogen pollution in this ecologically sensitive region.

Warsaw V STP discharges into a tributary of the Genesee River, which flows north into Lake Ontario, a major Great Lake. The watershed supports coldwater fisheries, including trout and salmon, and provides habitat for migratory waterfowl. Protecting water quality in this basin is critical for maintaining the ecological health of Lake Ontario and downstream communities.
