Glen Allan Utility District Wastewater Treatment Plant, Issaquena County, Mississippi

Glen Allan Utility District is a wastewater treatment facility located in rural Issaquena County, Mississippi, United States. Serving a small population of 556 residents, the plant provides advanced treatment to protect local water quality. The facility is situated inland, far from coastal areas, and operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for discharges. The plant utilizes advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 378.54 units and an actual discharge volume of 64.35 units, the facility operates well below its capacity, indicating room for future growth. The treatment level meets or exceeds the secondary treatment standards mandated by the EPA for municipal wastewater plants. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant plays a crucial role in protecting the region's aquatic ecosystems, including the Mississippi River and its tributaries, which support diverse fish and wildlife populations. By maintaining advanced treatment, the facility helps reduce nutrient loading and other pollutants that could impact downstream water quality.

The plant discharges into local streams that flow into the Mississippi River, a major waterway that drains into the Gulf of Mexico. The Mississippi River basin supports a rich diversity of aquatic life and is an important migratory corridor for birds and fish. Advanced treatment at this facility helps minimize nutrient pollution, which is critical for preventing hypoxic zones in the Gulf.
