The Plains WWTP and Sewers - Municipal Wastewater Treatment in The Plains, Ohio

The Plains WWTP and Sewers is a municipal wastewater treatment facility located in The Plains, Ohio, a small community in Athens County. Serving a population of about 4,000, the plant is part of the region's essential water infrastructure, treating domestic wastewater from the local area. As a small-scale facility in the United States, the plant is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting, administered by the Ohio Environmental Protection Agency. For communities of this size, secondary treatment is typically required, though specific treatment processes and capacity details are not publicly available in this record. The plant discharges treated effluent into local waterways that ultimately drain into the Ohio River basin. The receiving water body supports aquatic life and is part of a larger watershed that flows into the Mississippi River and the Gulf of Mexico, making proper treatment important for downstream water quality.

The Plains WWTP discharges into tributaries of the Hocking River, which flows into the Ohio River, a major tributary of the Mississippi River system. This watershed supports diverse aquatic species and provides drinking water for downstream communities. The plant's location in a rural area means effluent quality is critical for maintaining the ecological health of small streams that feed larger rivers.
