Summerville Boro STP is a municipal wastewater treatment plant located in Summerville, Jefferson County, Pennsylvania. The facility serves a population of approximately 1,050 residents and is situated in a rural inland area of the state. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. It has a designed capacity of 340.69 megaliters per year and currently discharges 227.13 megaliters annually, indicating operational capacity below its design limit. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Pennsylvania Department of Environmental Protection. The treated effluent is discharged into a local waterway that ultimately drains into the Allegheny River, a major tributary of the Ohio River. This river system supports diverse aquatic life and provides drinking water for downstream communities. The plant's operations help protect water quality in the region by reducing pollutant loads before discharge.

The plant discharges into a tributary of the Allegheny River, which flows into the Ohio River and eventually the Mississippi River. This watershed supports a variety of fish species and is an important ecological corridor in western Pennsylvania. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain the health of the receiving water body.
