Magnolia WWTP is a municipal wastewater treatment facility located in Magnolia, Columbia County, Arkansas. Serving a population of around 11,577, the plant is part of the region's infrastructure for managing domestic wastewater. The facility is situated inland, approximately 50 kilometers from the Gulf Coast, and discharges into local waterways that ultimately drain to the Gulf of Mexico.

The Arkansas Department of Energy and Environment oversees permitting and compliance for such facilities in the state. The plant's treated effluent enters the local watershed, which flows through the Ouachita River basin and eventually reaches the Mississippi River and the Gulf of Mexico. This downstream connection highlights the plant's role in protecting water quality in a region that supports diverse aquatic life and recreational uses. Proper treatment helps mitigate nutrient loading and other pollutants that could impact downstream ecosystems.

Magnolia WWTP discharges into the Ouachita River basin, which flows into the Mississippi River and ultimately the Gulf of Mexico. The receiving waters support diverse aquatic species and are used for recreation and fishing. The plant's location in a rural agricultural area means that nutrient management is important to prevent downstream algal blooms and hypoxia in the Gulf.
