Rogers WWTP - Municipal Wastewater Treatment in Rogers, Arkansas

Rogers WWTP is a municipal wastewater treatment facility located at 127 South Rainbow Road in Rogers, Benton County, Arkansas. Serving a population of about 55,964, the plant is a key component of the city's infrastructure, handling wastewater from residential and commercial sources in this growing northwestern Arkansas community. As a U.S. facility, Rogers WWTP operates under the Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For a plant serving a population of this size, secondary treatment is typically mandated, with potential additional nutrient removal requirements due to the sensitivity of downstream water bodies in the region. The plant's treated effluent likely discharges into a tributary of the Illinois River or directly into the river itself, which flows through the Ozark Plateau into Oklahoma. The Illinois River is a popular recreational waterway and supports diverse aquatic life, including several sensitive species. Downstream, the river joins the Arkansas River, which ultimately drains into the Mississippi River and the Gulf of Mexico.

Rogers WWTP discharges into the Illinois River watershed, a tributary of the Arkansas River that flows through the Ozark Mountains. The Illinois River is designated as an Extraordinary Resource Water in Arkansas, indicating high ecological value and requiring stringent water quality protections. Downstream, the Arkansas River feeds into the Mississippi River, which empties into the Gulf of Mexico, contributing to the hypoxic zone in the Gulf. Nutrient removal at the plant is critical to reducing downstream impacts.
