Corning WWTP - Secondary Treatment Plant in Clay County, Arkansas

Corning WWTP is a municipal wastewater treatment facility located in Clay County, Arkansas, United States. The plant serves a population of approximately 3,377 residents, classifying it as a small-scale treatment facility within the state's wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment process required by the U.S. Clean Water Act for municipal wastewater. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale are typically permitted by the Arkansas Department of Energy and Environment - Division of Environmental Quality. The designed capacity of 3,369.01 units indicates the plant's ability to handle peak flows, while the actual discharge volume of 170.34 units reflects current operational throughput. The treated effluent from Corning WWTP is discharged into a local water body that ultimately drains into the Mississippi River Basin. This region is part of the larger Mississippi River watershed, which supports diverse aquatic life and provides water resources for communities downstream. The plant's operations contribute to protecting local water quality and the ecological health of the receiving waters.

Corning WWTP discharges into a tributary of the Mississippi River Basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The watershed supports a variety of fish and wildlife species, including migratory birds and aquatic organisms. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, mitigating potential impacts on downstream ecosystems and the hypoxic zone in the Gulf.
