Perrysville WWTP and Sewer System - Secondary Treatment Plant in Ohio

Perrysville WWTP and Sewer System is a municipal wastewater treatment facility located in Perrysville, Ohio, United States. The plant serves a small population of 816 residents in the village and surrounding areas of Green Township, Ashland County. It operates as part of the local infrastructure managed by the village. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. Its designed capacity is 454.25 thousand cubic meters per year, and it currently discharges approximately 189.27 thousand cubic meters annually. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Ohio Environmental Protection Agency. The treated effluent is discharged into a local water body that ultimately drains into the Black Fork of the Mohican River, part of the Muskingum River watershed. This watershed flows to the Ohio River and then the Mississippi River, supporting diverse aquatic life and recreational uses downstream. The plant's location inland and away from coastal areas reduces direct marine impact.

The plant discharges into a tributary of the Black Fork of the Mohican River, which flows into the Muskingum River and eventually the Ohio River and Mississippi River. This inland watershed supports diverse freshwater ecosystems, including fish species such as smallmouth bass and sunfish. The plant's secondary treatment helps protect water quality in this region, which is important for local recreation and downstream communities.
