Beallsville WWTP and Sewer System | Advanced Wastewater Treatment in Ohio

Beallsville WWTP and Sewer System is a municipal wastewater treatment facility located in Beallsville, Sunsbury Township, Monroe County, Ohio. Serving a small population of 423, the plant provides advanced treatment to protect local water quality in this rural Appalachian region. The plant has a designed capacity of 302.83 thousand cubic meters per year and currently discharges 227.13 thousand cubic meters annually. As a US facility, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to safeguard receiving waters. Advanced treatment goes beyond secondary standards, typically including nutrient removal or disinfection. The treated effluent is discharged into a local stream within the Ohio River basin, which ultimately drains to the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems from nutrient pollution and pathogens, supporting biodiversity in the region's streams and rivers.

The plant discharges into a tributary of the Ohio River, part of the vast Mississippi River watershed that empties into the Gulf of Mexico. This region supports diverse aquatic life, including fish and macroinvertebrates, and is influenced by agricultural runoff. Advanced treatment helps reduce nutrient loads that could contribute to downstream hypoxia in the Gulf.
