JCUA PASCAGOULA POTW - Pascagoula, Mississippi Wastewater Treatment Plant

JCUA PASCAGOULA POTW is a municipal wastewater treatment plant serving the city of Pascagoula, Mississippi, in the United States. The plant serves a population of approximately 37,926, placing it in the medium-agglomeration category for US facilities. It is situated near the Gulf of Mexico, within 50 km of the coast, and its operations are subject to federal and state environmental regulations. As a US wastewater facility, JCUA PASCAGOULA POTW operates under the National Pollutant Discharge Elimination System (NPDES) permit program, established by the Clean Water Act. This regulatory framework requires permits that set limits on discharges to protect water quality. For a plant of this scale, secondary treatment is typically mandated, and permits may include additional requirements for nutrient removal or other pollutants depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into the Pascagoula River system, which flows into the Mississippi Sound and ultimately the Gulf of Mexico. This coastal environment supports diverse aquatic life, including fish, shellfish, and migratory birds. The plant plays a key role in protecting downstream water quality and the ecological health of the Gulf Coast region.

The plant discharges into the Pascagoula River, which flows into the Mississippi Sound and then the Gulf of Mexico. This coastal watershed supports diverse marine and estuarine habitats, including seagrass beds and oyster reefs, which are sensitive to nutrient pollution and require effective wastewater treatment to maintain ecological balance.
