Ash Flat WWTP - Advanced Wastewater Treatment in Ash Flat, Arkansas

Ash Flat WWTP is a municipal wastewater treatment facility located in Ash Flat, Sharp County, Arkansas, United States. The plant serves a population of approximately 1,082 residents, classifying it as a small-scale treatment facility within the state's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 567.81 megaliters and an annual discharge volume of 321.76 megaliters, the facility operates under the regulatory framework of the U.S. Clean Water Act, administered by the Arkansas Department of Energy and Environment. National Pollutant Discharge Elimination System (NPDES) permits govern its discharge limits and monitoring requirements. The treated effluent is discharged into local waterways that ultimately drain into the White River basin, a major tributary of the Mississippi River. The White River supports diverse aquatic life and provides drinking water for downstream communities. The plant's advanced treatment helps protect water quality in this ecologically significant watershed.

The plant discharges into receiving waters within the White River basin, which flows southward through Arkansas and eventually joins the Mississippi River. The White River is a vital habitat for fish species such as bass and catfish, and supports migratory birds along the Mississippi Flyway. The advanced treatment at Ash Flat WWTP reduces nutrient loading, helping to prevent eutrophication in downstream water bodies, including the Mississippi River delta and the Gulf of Mexico.
