EVANS CITY BORO STP - Jackson Township, Pennsylvania Wastewater Treatment Plant

EVANS CITY BORO STP is a municipal wastewater treatment plant located at 558 Lindsay Road in Jackson Township, Butler County, Pennsylvania. The facility serves a population of 2,453 and is part of the region's wastewater infrastructure, contributing to local water quality management. As a small-scale plant in the United States, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which is authorized by the Clean Water Act. This regulatory framework requires treatment facilities to meet effluent limitations that protect receiving water bodies, with secondary treatment being the minimum standard for municipal plants of this size. The plant discharges treated wastewater into a local waterway that ultimately drains into the Ohio River basin, which flows into the Mississippi River and then to the Gulf of Mexico. The facility plays a role in protecting downstream aquatic ecosystems and maintaining water quality in the region.

The plant's discharge enters a tributary of the Ohio River, which is part of the larger Mississippi River watershed. This river system supports diverse aquatic life and provides drinking water for millions. The plant's treatment processes help reduce nutrient and pollutant loads, protecting downstream habitats and recreational uses.
