Winstonville POTW - Secondary Wastewater Treatment in Winstonville, Mississippi

Winstonville POTW is a municipal wastewater treatment plant located in Winstonville, Bolivar County, Mississippi. It serves a small population of 500 residents, reflecting the rural character of the Mississippi Delta region. The plant is situated near the Mississippi River basin, which ultimately drains into the Gulf of Mexico. The plant provides secondary treatment, a standard level required under the U.S. Clean Water Act for municipal facilities. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity of 283.91 million gallons per year suggests it can handle peak flows, though current discharge volume is 34.07 million gallons per year. Winstonville POTW discharges treated effluent into local waterways that are part of the Mississippi River watershed. The Mississippi River and its tributaries support diverse aquatic life and are critical for regional ecology and economy. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) to protect downstream water quality.

The plant's effluent enters the Mississippi River basin, which flows south through the Mississippi Delta and into the Gulf of Mexico. This watershed is ecologically significant, supporting a variety of fish, birds, and other wildlife. The Gulf of Mexico receives nutrient loads from the basin, contributing to seasonal hypoxic zones. Proper treatment helps mitigate these impacts.
