Senecaville WWTP and Sewer System - Secondary Treatment Plant in Senecaville, Ohio

Senecaville WWTP and Sewer System is a municipal wastewater treatment facility located in Senecaville, Ohio, United States. The plant serves a small population of 453 residents and operates under secondary treatment standards, which is the minimum required by the US Clean Water Act for municipal wastewater treatment. The plant has a designed capacity of 189.27 million gallons per year and currently discharges 132.49 million gallons per year. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body, likely a tributary of the Muskingum River watershed, which flows into the Ohio River and ultimately the Mississippi River. The plant's inland location and small scale reduce its environmental footprint, but proper operation is essential to protect downstream aquatic ecosystems.

The plant discharges into a local stream within the Muskingum River basin, which drains into the Ohio River and then the Mississippi River. The watershed supports diverse aquatic life and provides habitat for fish and macroinvertebrates. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality in this inland river system.
