Shawnee WWTP and Sewer System - Advanced Wastewater Treatment in Shawnee, Ohio

The Shawnee WWTP and Sewer System is a municipal wastewater treatment facility located in Shawnee, Ohio, within Perry County. Serving a small population of around 770 people, the plant provides essential wastewater services to this rural community in the Appalachian region of southeastern Ohio. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the U.S. Clean Water Act. With a designed capacity of 352.04 megaliters per year and an actual discharge volume of 227.13 megaliters, the facility operates below its capacity, indicating room for future growth. As a U.S. facility, it operates under an EPA National Pollutant Discharge Elimination System (NPDES) permit issued by the Ohio Environmental Protection Agency, which sets effluent limits to protect water quality. The treated effluent is discharged into local streams that are part of the Muskingum River watershed, which ultimately flows into the Ohio River and then the Mississippi River. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's waterways.

The plant discharges into tributaries of the Muskingum River, which flows into the Ohio River and eventually the Mississippi River. This watershed supports diverse aquatic life and is important for regional biodiversity. The advanced treatment helps minimize nutrient and pollutant loads, protecting downstream habitats and water quality in the Ohio River basin.
