Lewisburg STP is a municipal wastewater treatment facility located in Lewisburg, Tennessee, serving a population of around 10,500. The plant is situated in Marshall County, part of the Middle Tennessee region, and operates under the regulatory framework of the U.S. Clean Water Act.

The treated effluent from Lewisburg STP is discharged into a local receiving water body that ultimately drains into the Tennessee River, a major tributary of the Ohio River and part of the Mississippi River system. This watershed supports diverse aquatic life and provides drinking water for downstream communities, making proper treatment essential for environmental and public health.

The plant discharges into a local stream that flows into the Tennessee River, which then joins the Ohio River and eventually the Mississippi River before reaching the Gulf of Mexico. The Tennessee River basin supports a variety of fish species and is an important migratory corridor for birds. The plant's operations help protect water quality in this ecologically significant watershed.
