N AND S SHENANGO STP - South Shenango Township, Pennsylvania Wastewater Treatment Plant

N AND S SHENANGO STP is a municipal wastewater treatment plant located in South Shenango Township, Crawford County, Pennsylvania. It serves a population of about 5,502 people, typical of a small community in the rural northwestern part of the state. The plant is situated near Dam Road, close to local waterways that drain into the Shenango River watershed. As a US facility, the plant operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Pennsylvania Department of Environmental Protection. For a plant of this scale, secondary treatment is the standard requirement, ensuring that effluent meets federal water quality standards before discharge. The plant's design capacity and treatment process details are not publicly available, but regulatory compliance is expected for continued operation. The treated effluent from the plant discharges into a receiving water body within the Shenango River basin, which flows into the Beaver River and eventually the Ohio River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant plays a key role in protecting local water quality and the ecological health of the region's streams and rivers.

The plant discharges into the Shenango River watershed, part of the larger Ohio River basin. The Shenango River flows through western Pennsylvania and into the Beaver River, which joins the Ohio River near Pittsburgh. This river system supports a variety of fish species and provides habitat for aquatic invertebrates. Downstream waters are used for recreation and as a drinking water source, making effective wastewater treatment essential for maintaining water quality and ecosystem health.
