Bay Springs POTW - Advanced Wastewater Treatment in Bay Springs, Mississippi

Bay Springs POTW (Publicly Owned Treatment Works) is a municipal wastewater treatment facility located in Bay Springs, Jasper County, Mississippi, United States. The plant serves a population of approximately 1,889 residents, classifying it as a small community system. It is situated inland, away from coastal zones, and operates under the regulatory framework of the U.S. Clean Water Act, administered by the Mississippi Department of Environmental Quality. The plant employs advanced treatment processes, which go beyond secondary treatment to remove additional nutrients and contaminants. With a designed capacity of 1,514.16 million gallons per year and an actual discharge volume of 609.45 million gallons per year, the facility operates well below its capacity, indicating room for future growth. As a small municipal plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting requirements, which set effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Pascagoula River basin, which flows into the Gulf of Mexico. The Pascagoula River is one of the last free-flowing river systems in the contiguous United States, supporting diverse aquatic life and important migratory species. The plant's advanced treatment helps minimize nutrient loading and protect downstream ecosystems.

The plant discharges into a tributary of the Pascagoula River system, which flows through southeastern Mississippi and empties into the Gulf of Mexico. The Pascagoula River basin is ecologically significant as one of the largest unimpeded river systems in the lower 48 states, supporting diverse fish, mussel, and bird populations. The advanced treatment at Bay Springs POTW reduces nutrient and pollutant loads, helping to maintain water quality in this sensitive coastal watershed.
