Nashville WWTP and Sewers - Secondary Treatment in Holmes County, Ohio

Nashville WWTP and Sewers is a municipal wastewater treatment facility located in Jefferson Township, Holmes County, Ohio. The plant serves a small population of 40 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all wastewater discharges. For small facilities like this, secondary treatment is the standard requirement, ensuring that effluent meets water quality standards to protect receiving waters. The designed capacity of 18.93 units indicates the plant's scale matches the local demand. The treated effluent from Nashville WWTP and Sewers is discharged into nearby streams that drain into the Muskingum River watershed, ultimately reaching the Ohio River and then the Mississippi River. This connection to a major river system underscores the importance of effective treatment to prevent nutrient pollution and protect downstream aquatic ecosystems, including the Gulf of Mexico.

The plant discharges into local tributaries of the Muskingum River, which flows into the Ohio River and then the Mississippi River, eventually reaching the Gulf of Mexico. This watershed supports diverse aquatic life and is part of a larger system affected by nutrient loading. The rural setting means the plant's discharge contributes to base flow in small streams, which are ecologically sensitive to changes in water quality.
