El Dorado North WWTP: Municipal Wastewater Treatment in El Dorado, Arkansas

El Dorado North WWTP is a municipal wastewater treatment facility located in El Dorado, Arkansas, serving a population of about 9,500. The plant is situated in Union County, within the southern region of the state, and plays a key role in managing local wastewater. As a U.S. facility, the plant operates under the Clean Water Act, administered by the EPA and the Arkansas Department of Energy and Environment. For a population of this size, secondary treatment is typically required to meet effluent limits before discharge. The plant's capacity and treatment process details are not publicly available, but regulatory standards ensure adequate treatment. The treated effluent is discharged into a local water body that eventually drains into the Ouachita River, a major tributary of the Mississippi River. This river system supports diverse aquatic life and provides water for communities downstream. Proper treatment is essential to protect water quality and ecosystem health.

The plant discharges into a local stream that flows into the Ouachita River, which ultimately joins the Mississippi River and empties into the Gulf of Mexico. The Ouachita River supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. Maintaining low nutrient and pollutant levels is critical to prevent eutrophication and protect downstream habitats.
