LAKE POTW Wastewater Treatment Plant, Lake, Mississippi

LAKE POTW is a municipal wastewater treatment facility located in Lake, Mississippi, United States. The plant serves a small community of approximately 1,044 residents and operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 454.25 units and an average daily discharge of 227.13 units, the facility operates well within its capacity. As a small-scale plant, it is subject to state-level oversight by the Mississippi Department of Environmental Quality. The treated effluent is discharged into a local water body that ultimately drains into the Pearl River basin, which flows south to the Gulf of Mexico. The plant plays a key role in protecting local water quality and supporting downstream aquatic ecosystems in the region.

The plant discharges into a receiving water body within the Pearl River basin, which flows through central Mississippi and Louisiana before emptying into the Gulf of Mexico. The downstream environment includes freshwater wetlands and estuarine habitats that support diverse fish and wildlife species. Maintaining secondary treatment standards helps reduce nutrient and pollutant loads to these sensitive ecosystems.
