MONACA BORO STP - Monaca, Pennsylvania Wastewater Treatment Plant

MONACA BORO STP is a municipal wastewater treatment plant located in Monaca, Beaver County, Pennsylvania, serving a population of around 6,286. The facility is part of the region's infrastructure managed under the U.S. Clean Water Act, which sets standards for wastewater treatment and discharge through National Pollutant Discharge Elimination System (NPDES) permits. As a small-to-medium agglomeration, the plant is expected to meet secondary treatment requirements to protect receiving waters. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency and the Pennsylvania Department of Environmental Protection. Plants of this scale typically employ biological treatment followed by disinfection to reduce pollutants before discharge. Its population served indicates a moderate-scale operation. Treated effluent from MONACA BORO STP discharges into a tributary of the Ohio River, which flows into the Mississippi River and ultimately the Gulf of Mexico. The Ohio River watershed supports diverse aquatic life and provides drinking water for millions. The plant's performance is critical to maintaining water quality in this ecologically and economically important river system.

The plant discharges into the Ohio River basin, a major tributary of the Mississippi River that drains into the Gulf of Mexico. The Ohio River supports diverse fish species and provides habitat for migratory birds. Downstream, the Mississippi River delta is an ecologically sensitive area with extensive wetlands and marine fisheries. Maintaining nutrient and pollutant removal at the plant helps prevent algal blooms and hypoxia in the Gulf.
