Massillon WWTP and Sewer System - Municipal Wastewater Treatment in Ohio

The Massillon WWTP and Sewer System is a municipal wastewater treatment facility located in Massillon, Stark County, Ohio, United States. It serves a population of approximately 92,325 residents, classifying it as a medium-to-large agglomeration under typical US regulatory frameworks. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. For a plant serving this population size, secondary treatment is the minimum standard, with potential requirements for additional nutrient removal depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into the Tuscarawas River, which flows into the Muskingum River and eventually the Ohio River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's performance is critical for maintaining water quality in this ecologically important river system.
