Conemaugh Township Indiana STP - Secondary Wastewater Treatment in Pennsylvania

Conemaugh Township Indiana STP is a municipal wastewater treatment facility located in Conemaugh Township, Indiana County, Pennsylvania, United States. The plant serves a small population of 350 residents, reflecting its role in a rural community within the state. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal plants. With a designed capacity of 189.27 megaliters per year and an actual discharge volume of 132.49 megaliters per year, the plant operates below its capacity, indicating room for future growth. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Pennsylvania Department of Environmental Protection, ensuring compliance with federal water quality standards. The treated effluent is discharged into local streams that drain into the Conemaugh River, a tributary of the Kiskiminetas River, which flows into the Allegheny River and ultimately the Ohio River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's secondary treatment helps protect these water bodies from nutrient pollution and pathogens.

The plant discharges into the Conemaugh River watershed, which flows into the Kiskiminetas River, then the Allegheny River, and finally the Ohio River. This river system supports a variety of fish species and is used for recreation and drinking water. The secondary treatment process reduces organic matter and suspended solids, helping to maintain water quality in this inland basin.
