Success WWTP - Advanced Wastewater Treatment in Clay County, Arkansas

Success WWTP is a municipal wastewater treatment facility located on County Road 134 in Clay County, Arkansas, serving a small population of 149 residents. The plant is situated in the rural Mississippi River region of northeastern Arkansas, an area characterized by agricultural activity and proximity to the Mississippi Alluvial Plain. The facility employs advanced treatment processes, which exceed the secondary treatment standard required by the U.S. Clean Water Act for most municipal plants. With a designed capacity of 162.77 volume units and a current discharge volume of 49.21, the plant operates well below its capacity, indicating room for future growth. As a U.S. facility, it operates under an EPA National Pollutant Discharge Elimination System (NPDES) permit issued by the Arkansas Department of Energy and Environment, which sets effluent limits to protect water quality. The treated effluent from Success WWTP ultimately drains into the Mississippi River watershed, a major hydrological system that flows into the Gulf of Mexico. The plant's advanced treatment helps reduce nutrient loading, which is critical for mitigating the hypoxic zone in the Gulf. The surrounding region includes sensitive aquatic habitats and supports diverse wildlife, making proper wastewater management essential for local and downstream ecosystems.

Success WWTP discharges into the Mississippi River basin, which flows through the Mississippi Alluvial Plain and eventually reaches the Gulf of Mexico. The plant's advanced treatment helps protect downstream water quality in a region where agricultural runoff and nutrient pollution are significant concerns. The Mississippi River supports a vast network of aquatic life and provides drinking water for millions, making the plant's role in reducing contaminants important for both local and far-reaching ecological health.
