Karns Beaver Creek STP - Knox County, Tennessee Wastewater Treatment Plant

Karns Beaver Creek STP is a municipal wastewater treatment plant located in Knox County, Tennessee, serving an estimated population of 51,000. The facility is part of the region's wastewater infrastructure, handling domestic and commercial flows from the surrounding community. As a US-based plant serving over 10,000 people, it falls under the National Pollutant Discharge Elimination System (NPDES) permitting program established by the Clean Water Act. This regulatory framework requires secondary treatment as a minimum standard for municipal facilities, with more stringent limits possible for discharges to sensitive waters. The plant's design and operation are subject to state-level oversight by the Tennessee Department of Environment and Conservation. The plant discharges treated effluent into local waterways that ultimately drain into the Tennessee River system. The Tennessee River flows westward to join the Ohio River, which then connects to the Mississippi River and the Gulf of Mexico. The watershed supports diverse aquatic life and provides drinking water for downstream communities, making proper treatment essential for protecting water quality and ecosystem health.

The plant discharges into the Tennessee River basin, which flows through eastern Tennessee before joining the Ohio River. This watershed supports a variety of fish species and provides habitat for freshwater mussels. Downstream waters eventually reach the Mississippi River and the Gulf of Mexico, where nutrient loading from upstream sources can contribute to hypoxic zones. Effective treatment at this plant helps reduce pollutant loads to the river system.
