YOUGH SAN AUTH SS Wastewater Treatment Plant, Dunbar Township, Pennsylvania

YOUGH SAN AUTH SS is a municipal wastewater treatment facility located on Front Street in Dickerson Run, Dunbar Township, Fayette County, Pennsylvania. The plant serves a population of approximately 2,090 residents and operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges. The facility is situated inland, away from coastal areas, and its treated effluent is released into the local water system. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 1,063.70 thousand gallons per day and an average daily discharge of 794.94 thousand gallons per day, the facility operates at a moderate utilization rate. As a US-based plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection, ensuring compliance with water quality standards. The receiving water body is part of the Monongahela River watershed, which flows north to join the Allegheny River at Pittsburgh, forming the Ohio River. This river system supports diverse aquatic life and provides drinking water for downstream communities. The plant's secondary treatment helps protect the ecological health of the watershed by reducing pollutant loads before discharge.

The plant discharges into a tributary of the Monongahela River, which flows through southwestern Pennsylvania and joins the Ohio River at Pittsburgh. The Monongahela watershed supports a variety of fish species and is an important corridor for migratory birds. The plant's secondary treatment helps maintain water quality in this region, which is influenced by both urban and industrial activities upstream.
