MARIETTA POTW HCR LAGOON - Prentiss County, Mississippi Wastewater Treatment Plant

MARIETTA POTW HCR LAGOON is a municipal wastewater treatment plant located in rural Prentiss County, Mississippi, United States. The plant serves a small population of 266 residents and is classified as a secondary treatment facility, which is the minimum standard for municipal wastewater under the US Clean Water Act. The plant has a designed capacity of 189.27 megaliters per year and currently discharges 151.42 megaliters annually, indicating it operates below its capacity. As a small facility in a rural area, it likely uses lagoon-based treatment, common for small communities in the region. The plant is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Mississippi Department of Environmental Quality. The treated effluent is discharged into local waterways that ultimately drain into the Tombigbee River basin, which flows south to the Gulf of Mexico. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region's aquatic habitats.

The plant's discharge enters small streams in the Tombigbee River watershed, which flows into the Mobile River system and eventually the Gulf of Mexico. This region supports diverse aquatic life, including fish and freshwater mussels. Proper treatment helps prevent nutrient pollution and pathogen contamination in downstream waters.
