Central Indiana County JSA Wastewater Treatment Plant, Center Township, Pennsylvania

Central Indiana County JSA is a municipal wastewater treatment facility located in Center Township, Indiana County, Pennsylvania. It serves a population of about 7,500 residents in the surrounding community, providing essential sanitation services to this inland region of the state. As a US-based plant serving a small agglomeration, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program established by the Clean Water Act. This regulatory framework requires permits that set effluent limits and monitoring requirements to protect water quality. The plant discharges treated wastewater into local waterways that drain into the Ohio River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. Its operations are important for maintaining water quality in the region's streams and supporting downstream aquatic ecosystems.

The plant discharges into tributaries of the Ohio River system, which flows into the Mississippi River and then the Gulf of Mexico. This watershed supports diverse aquatic life and provides drinking water for communities downstream. The plant's location in a rural area means its discharge can affect local streams that are ecologically sensitive, particularly during low-flow conditions.
