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

The Danville WWTP and Sewer System is a municipal wastewater treatment facility located on Richardson Street in Danville, Ohio, within Knox County. Serving a population of approximately 1,104 residents, the plant provides advanced treatment to protect local water quality. The facility operates under the regulatory framework of the U.S. Clean Water Act, administered by the Ohio Environmental Protection Agency, which issues National Pollutant Discharge Elimination System (NPDES) permits to control discharges. The plant treats an average daily flow of 946.35 cubic meters, with a designed capacity of 757.08 cubic meters, indicating it operates above its nominal capacity. Advanced treatment processes are employed to remove nutrients and other pollutants beyond secondary treatment standards, ensuring a high level of effluent quality. This treatment level is appropriate for a small community and helps meet state water quality standards. The treated effluent is discharged to a local receiving water body, which ultimately drains into the Muskingum River watershed and then the Ohio River. The Ohio River is a major tributary of the Mississippi River, supporting diverse aquatic life and providing drinking water for millions downstream. The plant's advanced treatment helps reduce nutrient loading and protect the ecological health of these downstream waters.

The Danville WWTP discharges into a local stream that flows into the Muskingum River basin, part of the larger Ohio River watershed. The Ohio River is a critical water resource for the region, supporting diverse fish populations and serving as a migratory corridor for birds. The plant's advanced treatment helps minimize nutrient pollution, which can cause algal blooms and hypoxia in downstream waters, including the Gulf of Mexico.
