West Liberty WWTP and Sewer System | Ohio Wastewater Treatment Plant

The West Liberty WWTP and Sewer System is a municipal wastewater treatment facility located in West Liberty, Ohio, serving a population of approximately 1,813 residents. The plant is situated in Liberty Township, Logan County, and is part of the village's public infrastructure for managing domestic wastewater. As a small-scale facility in the United States, the plant operates under the regulatory framework of the Clean Water Act, administered by the Ohio Environmental Protection Agency. Facilities of this size are typically required to meet secondary treatment standards through the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent from the plant is discharged into a local waterway that ultimately drains into the Ohio River basin. The plant plays a key role in protecting downstream aquatic ecosystems by reducing pollutant loads before discharge, supporting water quality in the region's streams and rivers.

The plant discharges into a tributary of the Scioto River, which flows southward to join the Ohio River. The Scioto River watershed supports diverse aquatic life and provides habitat for fish and macroinvertebrates. The plant's treatment helps maintain water quality in this ecologically important river system, which is a major tributary of the Mississippi River basin.
