Jasper WWTP - Advanced Wastewater Treatment in Jasper, Arkansas

Jasper WWTP is a municipal wastewater treatment facility located on AR 74 in Jasper, Newton County, Arkansas. It serves a small population of 466 residents, reflecting the rural character of the Ozark region. The plant is situated inland, far from coastal influences, and its operations are part of the local infrastructure managed by the community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 378.54 thousand gallons per day and a discharge volume of 601.88 thousand gallons per day, the facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Arkansas Department of Energy and Environment. Advanced treatment ensures high-quality effluent that meets stringent permit limits for nutrients and other pollutants. The treated effluent is discharged into a receiving water body within the Arkansas River basin, which ultimately flows into the Mississippi River and then the Gulf of Mexico. The plant's advanced treatment helps protect local streams and the downstream aquatic ecosystem, supporting biodiversity and water quality in the region.

The plant discharges into a tributary of the Arkansas River, which flows through the Ozark Mountains and eventually joins the Mississippi River. This watershed supports diverse aquatic life, including fish species such as smallmouth bass and Ozark hellbender. The advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream water bodies and the Gulf of Mexico hypoxic zone.
