Huntington WWTP - Advanced Wastewater Treatment in Huntington, Arkansas

Huntington WWTP is a municipal wastewater treatment plant located in Huntington, Arkansas, United States. It serves a small population of 635 residents in the Sebastian County area. The plant operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. The plant provides advanced treatment, which goes beyond secondary treatment to remove additional nutrients and contaminants. It has a designed capacity of 416.39 megaliters per year and currently discharges 317.98 megaliters per year, indicating it is operating below capacity. Advanced treatment typically includes processes such as tertiary filtration or nutrient removal. The treated effluent is discharged into a local water body, likely a tributary of the Arkansas River, which flows into the Mississippi River and eventually the Gulf of Mexico. The plant plays a key role in protecting local water quality in the Arkansas River basin, supporting aquatic life and downstream ecosystems.

The plant discharges into a local water body within the Arkansas River basin. The Arkansas River flows southeast through Oklahoma and Arkansas before joining the Mississippi River, which empties into the Gulf of Mexico. This watershed supports diverse aquatic habitats and is important for migratory birds and fish species. The advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in downstream waters.
