Savannah STP Wastewater Treatment Plant, Savannah, Tennessee

Savannah STP is a municipal wastewater treatment plant located on Legion Drive in Savannah, Hardin County, Tennessee. Serving a population of around 7,500, the facility is part of the region's infrastructure for managing domestic wastewater in West Tennessee. Under the U.S. Clean Water Act, municipal treatment plants of this scale are typically required to provide secondary treatment, which involves biological processes to reduce organic pollutants and suspended solids. The plant's operations are regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Tennessee Department of Environment and Conservation. The treated effluent from Savannah STP is discharged into a local waterway that ultimately drains into the Tennessee River, a major tributary of the Ohio River and part of the Mississippi River basin. This downstream connection supports diverse aquatic life and provides water resources for communities along the river system.

The plant discharges into a local stream that flows into the Tennessee River, which then joins the Ohio River and eventually the Mississippi River. This watershed supports a variety of fish and wildlife, including species that rely on healthy water quality. The Tennessee River basin is an important ecological corridor in the southeastern United States.
