Redfield WWTP - Secondary Treatment Plant in Jefferson County, Arkansas

Redfield WWTP is a municipal wastewater treatment facility located in Jefferson County, Arkansas, United States. The plant serves a small population of around 1,297 residents, reflecting its role in a rural or suburban community. Its location inland, far from coastal areas, shapes its environmental context and discharge considerations. The plant provides secondary treatment, which is the standard biological treatment process required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 454.25 million gallons per year and an actual discharge volume of 230.91 million gallons per year, the facility operates well below its capacity, indicating room for future growth or seasonal variability. As a U.S. facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent from Redfield WWTP is discharged into a local water body, likely a stream or river within the Arkansas River basin. The Arkansas River ultimately flows into the Mississippi River, which drains into the Gulf of Mexico. This downstream connection highlights the plant's role in protecting water quality in a major river system that supports diverse aquatic life and provides drinking water for millions.

Redfield WWTP discharges into a local water body within the Arkansas River basin. The Arkansas River flows southeast to join the Mississippi River, which empties into the Gulf of Mexico. This watershed supports a variety of aquatic species and is an important migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, mitigating the risk of eutrophication in downstream waters.
