Blytheville North WWTP - Mississippi County, Arkansas Wastewater Treatment

Blytheville North WWTP is a municipal wastewater treatment facility located in Mississippi County, Arkansas, United States. Serving a population of around 4,033, the plant is part of the region's infrastructure for managing domestic wastewater from the Blytheville area. As a small-to-medium agglomeration, the plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. Facilities of this scale typically employ secondary treatment to meet federal and state effluent standards. The plant's treated effluent is discharged into local waterways that ultimately drain into the Mississippi River. The Mississippi River basin supports diverse aquatic life and provides drinking water for millions, making proper wastewater treatment critical to maintaining water quality and ecosystem health.

The plant discharges into the Mississippi River basin, a vast watershed that drains much of the central United States. The river supports a rich diversity of fish and wildlife, including migratory birds and endangered species. Downstream, the Mississippi flows into the Gulf of Mexico, where nutrient pollution from upstream sources can contribute to hypoxic zones. Effective treatment at plants like Blytheville North helps reduce nutrient loads and protect downstream aquatic ecosystems.
