VARDAMAN POTW - Vardaman, Mississippi Wastewater Treatment Plant

VARDAMAN POTW is a municipal wastewater treatment plant located in Vardaman, Calhoun County, Mississippi, United States. The facility serves a small community of approximately 910 residents, reflecting its role in managing domestic wastewater for this rural town. As a publicly owned treatment works (POTW), it is part of the national infrastructure regulated under the U.S. Clean Water Act. The plant provides secondary treatment, which is the standard level required by the U.S. Environmental Protection Agency (EPA) for municipal wastewater facilities. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity is 1,294.61 m³/day, with an average daily discharge volume of 454.25 m³/day, indicating it operates well below its capacity. Under the National Pollutant Discharge Elimination System (NPDES), such facilities must obtain permits that set effluent limits to protect water quality. The treated effluent from VARDAMAN POTW is discharged into a local water body, likely a stream or creek within the Tombigbee River basin, which ultimately drains into the Gulf of Mexico. The plant's inland location, over 50 km from the coast, reduces direct marine impact. However, its discharge contributes to the overall nutrient and pollutant load in the watershed, affecting downstream aquatic ecosystems.

VARDAMAN POTW discharges into a local water body within the Tombigbee River watershed. The Tombigbee River flows south to join the Alabama River, forming the Mobile River, which empties into Mobile Bay and the Gulf of Mexico. This watershed supports diverse aquatic life, including fish and invertebrates, and is an important migratory corridor for birds. Nutrient loading from wastewater can contribute to eutrophication in downstream estuaries, making effective treatment critical for ecological health.
