Gainesboro STP - Secondary Wastewater Treatment in Gainesboro, Tennessee

Gainesboro STP is a municipal wastewater treatment facility located in Gainesboro, Jackson County, Tennessee. Serving a population of 923, the plant provides secondary treatment to manage domestic wastewater from the community. The facility operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment as the minimum standard for municipal plants. The plant has a designed capacity of 908.50 volume units and a current discharge volume of 317.98, indicating operational headroom. As a secondary treatment facility, it uses biological processes to reduce organic matter and suspended solids before discharge. The plant's permit is administered by the Tennessee Department of Environment and Conservation, ensuring compliance with state and federal water quality standards. The treated effluent from Gainesboro STP is discharged into local streams that flow into the Cumberland River, a major tributary of the Ohio River and ultimately the Mississippi River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's location inland, away from coastal areas, reduces direct marine impact but requires careful management to protect freshwater ecosystems.

The plant discharges into local waterways that drain into the Cumberland River, which flows through Tennessee and Kentucky before joining the Ohio River. The Cumberland River basin supports a variety of fish species and provides habitat for freshwater mussels. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to algal blooms in downstream reservoirs.
