Hot Springs Regional WWTP | Wastewater Treatment in Hot Springs, Arkansas

Hot Springs Regional WWTP is a municipal wastewater treatment facility located at 321 Davidson Drive in Hot Springs, Arkansas. Serving an estimated population of 34,218, the plant is a key component of the city's infrastructure, handling domestic and industrial wastewater from the Hot Springs area. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal facilities of this scale. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Arkansas Department of Energy and Environment, governs discharge limits and monitoring requirements to ensure compliance with water quality standards. The plant's treated effluent is discharged into a receiving water body within the Ouachita River basin, which flows southward through Arkansas and Louisiana before emptying into the Mississippi River. This watershed supports diverse aquatic life and provides drinking water for downstream communities, making proper treatment essential for ecological and public health.

The plant discharges into a waterway within the Ouachita River basin, which drains into the Mississippi River and ultimately the Gulf of Mexico. This watershed supports diverse aquatic species, including fish and macroinvertebrates, and provides habitat for migratory birds. The region's forested terrain and seasonal rainfall patterns influence runoff and water quality, requiring careful management of nutrient and pollutant loads to prevent eutrophication and maintain downstream ecosystem health.
