Jackson POTW Trahon and Big Creek Wastewater Treatment Plant, Mississippi

Jackson POTW Trahon and Big Creek is a municipal wastewater treatment plant located in Jackson, Mississippi, serving a population of about 19,440. The facility is situated in Hinds County and is part of the city's wastewater infrastructure, managed under the regulatory framework of the US Clean Water Act. As a plant serving a medium-sized agglomeration, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting requirements. Under the Clean Water Act, such facilities must meet secondary treatment standards to control pollutants before discharge. The plant's design and operation align with these federal and state regulations to protect water quality. The treated effluent from the plant is discharged into local streams that flow into the Pearl River, which ultimately drains into the Gulf of Mexico. This river system supports diverse aquatic life and provides habitat for fish and wildlife. The plant plays a crucial role in maintaining the ecological health of the Pearl River basin by reducing nutrient and pollutant loads.

The plant discharges into tributaries of the Pearl River, which flows south through Mississippi and Louisiana before emptying into the Gulf of Mexico. The Pearl River basin supports a variety of fish species and provides critical habitat for migratory birds. The plant's operations help mitigate nutrient pollution that could otherwise contribute to hypoxic zones in the Gulf.
