Warsaw WWTP and Sewer System | Advanced Treatment Plant in Warsaw, Ohio

Warsaw WWTP and Sewer System is a municipal wastewater treatment facility located on Mill Street in Warsaw, Coshocton County, Ohio. The plant serves a small population of 781 residents, reflecting the rural character of the area. It operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the Clean Water Act for municipal facilities. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) or other specialized processes to meet stringent water quality standards. The plant has a designed capacity of 643.52 m³/day and currently treats an average daily flow of 378.54 m³/day, indicating operational headroom for future growth. The treated effluent is discharged to a receiving water body within the Muskingum River watershed, which ultimately drains to the Ohio River and then the Mississippi River system. This discharge contributes to the ecological health of downstream aquatic habitats, supporting diverse fish and macroinvertebrate communities. The advanced treatment level helps protect water quality in the region, particularly in areas sensitive to nutrient pollution.

The plant discharges into a tributary of the Muskingum River, which flows into the Ohio River and eventually the Mississippi River. The local watershed supports diverse aquatic life, including game fish species and freshwater mussels. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream water bodies and maintaining ecological balance in the region.
