Malvern WWTP - Hot Spring County, Arkansas Wastewater Treatment Plant

Malvern WWTP is a municipal wastewater treatment facility located in Hot Spring County, Arkansas, serving a population of about 10,559. The plant is situated in the Ouachita River basin, contributing to regional water quality management. As a U.S. facility, Malvern WWTP is subject to the Clean Water Act and operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Arkansas Department of Energy and Environment - Division of Environmental Quality. For a plant serving this population size, secondary treatment is typically required, with possible additional nutrient controls depending on the receiving water body's sensitivity. The treated effluent from Malvern WWTP discharges into local waterways that ultimately flow into the Ouachita River, a major tributary of the Mississippi River system. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in the region.

Malvern WWTP discharges into streams within the Ouachita River watershed, which flows southward to the Mississippi River and eventually the Gulf of Mexico. The Ouachita River supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for freshwater mussels. The plant's operations help mitigate nutrient loading and protect downstream water quality in this ecologically significant river system.
