Gnadenhutten WWTP and Sewer System - Secondary Treatment Plant in Ohio

Gnadenhutten WWTP and Sewer System is a municipal wastewater treatment facility located in Gnadenhutten, Ohio, a village in Tuscarawas County. The plant serves a population of approximately 1,280 residents, reflecting a small community-scale operation typical of rural Ohio. 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 946.35 thousand cubic meters per year, with an actual discharge volume of 605.67 thousand cubic meters per year. As a facility in the United States, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Ohio Environmental Protection Agency, ensuring compliance with effluent limits. The treated effluent is discharged into a local waterway that ultimately drains into the Tuscarawas River, a tributary of the Muskingum River, which flows to the Ohio River and then the Mississippi River. This connection to the Gulf of Mexico highlights the plant's role in protecting downstream water quality across multiple states.

The plant discharges into a local stream that feeds the Tuscarawas River, part of the Muskingum River basin. This watershed supports diverse aquatic life and provides habitat for fish and macroinvertebrates. The downstream Ohio River and Mississippi River system is a major migratory corridor for birds and fish, making nutrient and pollutant control critical for ecosystem health. The plant's secondary treatment helps reduce organic load and suspended solids, protecting these waters from eutrophication and other impacts.
