STRATTANVILLE BORO STP - Secondary Wastewater Treatment in Clarion Township, Pennsylvania

STRATTANVILLE BORO STP is a municipal wastewater treatment facility located in Clarion Township, Clarion County, Pennsylvania. The plant serves a small population of 662 residents and operates under secondary treatment, which is the standard for most U.S. plants under the Clean Water Act. The plant has a designed capacity of 567.81 thousand gallons per day and currently discharges an average of 264.98 thousand gallons per day. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids, meeting the effluent limits set by the National Pollutant Discharge Elimination System (NPDES) permit program. The treated effluent is discharged into a local waterway within the Allegheny River basin, which ultimately flows into the Ohio River and then the Mississippi River to the Gulf of Mexico. The plant plays a key role in protecting local water quality and downstream ecosystems in the Allegheny watershed.

The plant discharges into a tributary of the Allegheny River, which flows through western Pennsylvania before joining the Ohio River. The Allegheny River supports diverse aquatic life, including several species of freshwater mussels and fish. Downstream, the Ohio and Mississippi Rivers carry the water to the Gulf of Mexico, where nutrient loading from upstream sources can contribute to hypoxic zones. The plant's secondary treatment helps reduce organic pollutants and nutrients, mitigating its impact on this extensive river system.
