East Sevier County UD STP - Advanced Wastewater Treatment in Sevier County, Tennessee

East Sevier County UD STP is a municipal wastewater treatment facility located in Sevier County, Tennessee, within the East Tennessee region. The plant serves a small population of approximately 1,100 residents, providing advanced treatment to protect local water quality. The facility operates with advanced treatment processes, which exceed the secondary treatment standard required by the U.S. Clean Water Act for most municipal plants. Its designed capacity of 155.20 units and current discharge volume of 94.64 units indicate operational headroom. As a U.S. facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Tennessee Department of Environment and Conservation, ensuring compliance with federal water quality standards. The treated effluent is discharged into a local waterway that ultimately drains into the Tennessee River system, a major tributary of the Ohio and Mississippi Rivers. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The advanced treatment helps minimize nutrient and pollutant loading, contributing to the ecological health of the region.

The plant discharges into a tributary of the Tennessee River, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This watershed is ecologically significant, supporting diverse fish and wildlife habitats. Advanced treatment reduces nutrient pollution, helping to prevent algal blooms and maintain water quality in downstream reservoirs and coastal zones.
