Lumberton POTW is a municipal wastewater treatment plant located in Lumberton, Lamar County, Mississippi, United States. The facility serves a population of approximately 3,376 residents and operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 1,362.74 thousand cubic meters per year, the plant treats an average annual discharge volume of 757.08 thousand cubic meters. The facility is operated as a publicly owned treatment works (POTW) and is subject to National Pollutant Discharge Elimination System (NPDES) permitting. The treated effluent is discharged into local waterways that drain into the Pascagoula River basin, eventually reaching the Gulf of Mexico. The plant plays a key role in protecting downstream water quality and aquatic habitats in the region's coastal ecosystems.

The plant's discharge enters the Pascagoula River watershed, which flows into the Mississippi Sound and the Gulf of Mexico. This coastal ecosystem supports diverse marine life, including fish, shellfish, and migratory birds. Secondary treatment helps reduce nutrient loads that could contribute to algal blooms in the sensitive Gulf coastal waters.
