Doddsville POTW - Secondary Wastewater Treatment in Sunflower County, Mississippi

Doddsville POTW (Publicly Owned Treatment Works) is a municipal wastewater facility located in Sunflower County, Mississippi, serving a small population of 296 residents. The plant is situated in the Mississippi Delta region, an area characterized by flat, agricultural terrain and a network of drainage canals and rivers. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 189.27 million gallons per year and an actual discharge volume of 75.71 million gallons per year, the plant operates well below its capacity. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale must meet effluent limits for biochemical oxygen demand and total suspended solids. The treated effluent from Doddsville POTW ultimately drains into the Mississippi River Basin, which flows into the Gulf of Mexico. The receiving waters support diverse aquatic life and are part of a larger watershed that includes ecologically sensitive areas such as wetlands and floodplains that provide critical habitat for migratory birds and fish species.

The plant discharges into local streams that are part of the Mississippi River Basin, which drains into the Gulf of Mexico. The Mississippi Delta region includes extensive wetlands and floodplains that support diverse aquatic species and serve as an important migratory corridor for waterfowl. The plant's secondary treatment helps reduce nutrient loading that could contribute to hypoxia in the Gulf.
