Jasper Lagoon Wastewater Treatment Plant, Jasper, Tennessee

Jasper Lagoon is a wastewater treatment facility located in Jasper, Tennessee, within Marion County. The plant serves a population of approximately 2,500 residents, classifying it as a small-scale municipal treatment system in the southeastern United States. As a lagoon-based system, the plant typically relies on natural biological processes for treatment. Under the US Clean Water Act, facilities of this size are regulated through the National Pollutant Discharge Elimination System (NPDES), administered by the Tennessee Department of Environment and Conservation. Lagoons are common in rural areas due to lower operational costs and energy requirements. The treated effluent from Jasper Lagoon is discharged into local waterways that ultimately drain into the Tennessee River system, part of the larger Mississippi River basin. The Tennessee River supports diverse aquatic life and provides drinking water for downstream communities, making proper treatment essential for regional water quality.

The plant discharges into tributaries of the Tennessee River, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. The Tennessee River watershed supports a variety of fish species and provides habitat for freshwater mussels. Maintaining effective treatment is important to prevent nutrient loading and protect downstream ecosystems.
