COAHOMA POTW - Clarksdale, Mississippi Advanced Wastewater Treatment Plant

COAHOMA POTW is a municipal wastewater treatment facility located in Clarksdale, Coahoma County, Mississippi. Serving a small population of 347, the plant provides advanced treatment to protect local water quality. Its operations are part of the broader wastewater infrastructure in the Mississippi Delta region. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the US Clean Water Act for most municipal facilities. With a designed capacity of 189.27 volume units and an average daily discharge of 147.63, it operates below capacity, indicating room for future growth. As a US facility, it is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Mississippi Department of Environmental Quality. The treated effluent is discharged into a local waterway that ultimately drains into the Mississippi River, a major ecological and economic artery. The plant's advanced treatment helps reduce nutrient loading and protect downstream aquatic habitats, including the Mississippi River's diverse fish and wildlife populations.

The plant discharges into a tributary of the Mississippi River, which flows into the Gulf of Mexico. The Mississippi River basin supports a vast array of aquatic life and is a critical migratory corridor for birds and fish. Advanced treatment at this plant helps mitigate nutrient pollution that can contribute to hypoxic zones in the Gulf, supporting downstream ecosystem health.
