TOONE WWTP - Secondary Treatment Plant in Hardeman County, Tennessee

TOONE WWTP is a municipal wastewater treatment facility located in Hardeman County, Tennessee, serving a small population of 350 residents. The plant provides secondary treatment, which is the standard level for small communities in the United States under the Clean Water Act. The plant has a designed capacity of 113.56 cubic meters per day and currently treats an average daily flow of 75.71 cubic meters. As a small facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Tennessee Department of Environment and Conservation, ensuring compliance with federal water quality standards. The treated effluent is discharged to a local receiving water body, which ultimately drains into the Mississippi River watershed. This region of West Tennessee features agricultural and rural landscapes, and the plant plays a key role in protecting downstream water quality and aquatic habitats.

TOONE WWTP discharges into a local stream that flows into the Hatchie River, a major tributary of the Mississippi River. The Hatchie River is one of the longest free-flowing rivers in the southeastern United States and supports diverse aquatic life, including several species of freshwater mussels and fish. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, protecting the ecological health of this important river system.
