Tylertown POTW - Secondary Wastewater Treatment in Tylertown, Mississippi

Tylertown POTW (Publicly Owned Treatment Works) is a municipal wastewater treatment facility located in Tylertown, Walthall County, Mississippi. The plant serves a population of approximately 2,431 residents, providing essential sanitation services for this small community in the southern United States. The facility operates with secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater plants. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale must meet effluent limits to protect receiving waters. The plant has a designed capacity of 1,324.89 volume units and currently discharges 870.65 volume units, indicating it operates below its maximum capacity. The treated effluent from Tylertown POTW is discharged into local streams that are part of the Pearl River basin, ultimately draining into the Gulf of Mexico. This discharge contributes to the ecological health of downstream waters, supporting aquatic life and recreational uses in the region.

The plant discharges into tributaries of the Pearl River, which flows south through Mississippi and Louisiana before emptying into the Gulf of Mexico. The Pearl River watershed supports diverse aquatic habitats, including wetlands and bottomland hardwood forests, which provide critical ecosystem services such as flood control and water filtration. The Gulf of Mexico is a major marine ecosystem that faces challenges from nutrient pollution, making effective wastewater treatment important for coastal water quality.
