CLARKTON WWTP - Clarkton, Missouri Wastewater Treatment Plant

CLARKTON WWTP is a municipal wastewater treatment facility located at 456 East Commercial Street in Clarkton, Dunklin County, Missouri. The plant serves a population of approximately 1,288 residents, classifying it as a small-scale facility within the state's wastewater infrastructure. The plant provides secondary treatment, a standard level required by the U.S. Clean Water Act for municipal facilities. With a designed capacity of 757.08 thousand cubic meters per year and an actual discharge volume of 567.81 thousand cubic meters, the plant operates well within its capacity. As a U.S. facility, it operates under an EPA National Pollutant Discharge Elimination System (NPDES) permit issued by the Missouri Department of Natural Resources, ensuring compliance with federal water quality standards. The treated effluent is discharged into local surface waters that drain into the Mississippi River basin. This water body supports aquatic life and is part of a larger watershed that ultimately reaches the Gulf of Mexico. The plant's operations help protect downstream ecosystems by reducing pollutant loads before discharge.

The plant discharges into local streams that flow into the Mississippi River basin, which drains into the Gulf of Mexico. This watershed supports diverse aquatic species and is an important migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient and organic loads, mitigating potential impacts on downstream water quality and the hypoxic zone in the Gulf.
