Peters Township Brush Run STP - Pennsylvania Wastewater Treatment Plant

Peters Township Brush Run STP is a municipal wastewater treatment plant located in Peters Township, Washington County, Pennsylvania. It serves a population of approximately 7,000 people in the Thompsonville area. The plant is part of the region's wastewater infrastructure, managed under local municipal authority. As a US facility serving a small-to-medium community, the plant operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. Plants of this scale typically employ secondary treatment to meet federal standards. The population served suggests a moderate-scale operation. The plant discharges treated effluent into Brush Run, a tributary of Chartiers Creek, which flows into the Ohio River and ultimately the Mississippi River system. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's performance is critical to maintaining the ecological health of these waterways.

The plant discharges into Brush Run, a stream that flows into Chartiers Creek, a major tributary of the Ohio River. The Ohio River drains into the Mississippi River, which empties into the Gulf of Mexico. This watershed supports a variety of fish and wildlife, and the plant's effluent must meet NPDES limits to prevent nutrient pollution and protect downstream ecosystems.
