CLEVELAND WWTP | Bolivar County, Mississippi Wastewater Treatment Plant

CLEVELAND WWTP is a municipal wastewater treatment facility located in Bolivar County, Mississippi, serving a population of about 19,500. The plant is situated inland, more than 50 kilometers from the coast, and treats wastewater from the Cleveland area. As a US facility, the plant operates under the National Pollutant Discharge Elimination System (NPDES) permit program established by the Clean Water Act. For a population of this scale, secondary treatment is typically required, which involves biological processes to reduce organic matter and suspended solids. The plant's discharge must meet federal and state water quality standards to protect the receiving water body. The treated effluent likely discharges into a local waterway that flows into the Mississippi River basin, eventually reaching the Gulf of Mexico. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in the region.

The plant discharges into a local tributary within the Mississippi River basin, which drains into the Gulf of Mexico. The watershed supports diverse aquatic life and is an important migratory corridor for fish and birds. Proper treatment helps prevent nutrient pollution that could contribute to hypoxia in the Gulf.
