Conemaugh Township Tire Hill STP - Pennsylvania Wastewater Treatment Plant

Conemaugh Township Tire Hill STP is a municipal wastewater treatment plant located in Conemaugh Township, Somerset County, Pennsylvania. Serving a population of approximately 5,105, the facility is part of the region's wastewater infrastructure, treating domestic sewage from the local community. Under the US Clean Water Act, municipal treatment plants of this scale are typically required to provide secondary treatment, which removes at least 85% of biochemical oxygen demand and suspended solids. The plant's discharge is regulated through a National Pollutant Discharge Elimination System (NPDES) permit issued by the Pennsylvania Department of Environmental Protection, ensuring compliance with water quality standards. The treated effluent from the plant is discharged into a local waterway that ultimately drains into the Ohio River basin, contributing to the Mississippi River watershed. This connection to a major river system underscores the importance of effective treatment in protecting downstream aquatic ecosystems and drinking water sources.

The plant's discharge enters a tributary of the Conemaugh River, which flows into the Kiskiminetas River, then the Allegheny River, and eventually the Ohio River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The region's karst geology and agricultural land use require careful nutrient management to prevent eutrophication in receiving waters.
