Elizabethton WWTP | Wastewater Treatment Plant in Elizabethton, Tennessee

Elizabethton WWTP is a municipal wastewater treatment facility located at 217 Sycamore Shoals Drive in Elizabethton, Carter County, Tennessee. The plant serves a population of about 14,300 people, classifying it as a medium-sized agglomeration under U.S. regulatory frameworks. As a U.S. facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Tennessee Department of Environment and Conservation. For plants of this scale, secondary treatment is typically required, with possible additional nutrient removal depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into the Watauga River, which flows into the South Fork Holston River, part of the Tennessee River basin. This watershed ultimately drains into the Mississippi River and the Gulf of Mexico. The Watauga River supports diverse aquatic life and is used for recreation, making proper treatment essential for downstream water quality.

The Watauga River flows through northeastern Tennessee and joins the South Fork Holston River, which feeds into the Tennessee River system. This watershed is part of the larger Mississippi River basin, draining into the Gulf of Mexico. The river supports a variety of fish species and provides habitat for freshwater mussels. Downstream reservoirs, such as Boone Lake, are used for recreation and hydropower, highlighting the importance of maintaining nutrient and pollutant limits to prevent eutrophication.
