Saline Co WandSFB WWTP, Alexander, Arkansas - Advanced Wastewater Treatment

Saline Co WandSFB WWTP is a wastewater treatment facility located in Alexander, Saline County, Arkansas, serving a population of approximately 1,008 residents. The plant is situated in the central part of the state, within the Arkansas River basin, and operates as part of the region's municipal wastewater infrastructure. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 757.08 cubic meters per day and a current discharge volume of 215.77 cubic meters per day, the plant operates well below its capacity, indicating room for future growth. Under the U.S. Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Arkansas Department of Energy and Environment. The treated effluent from the plant is discharged into local streams that ultimately flow into the Arkansas River, a major tributary of the Mississippi River. This discharge contributes to the overall water quality of the region, supporting aquatic life and downstream ecosystems. The advanced treatment level helps minimize nutrient loading, which is beneficial for preventing eutrophication in receiving waters.

The plant discharges into the Arkansas River basin, which drains into the Mississippi River and eventually the Gulf of Mexico. The watershed supports diverse aquatic habitats and is important for migratory fish species. Advanced treatment helps reduce nutrient pollution, which is critical for mitigating hypoxia in the Gulf of Mexico.
