Lewisville WWTP - Advanced Wastewater Treatment in Lewisville, Arkansas

Lewisville WWTP is a municipal wastewater treatment plant located in Lewisville, Lafayette County, Arkansas, United States. The facility serves a population of approximately 1,280 residents, providing advanced treatment to protect local water quality. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 757.08 thousand cubic meters per year and an actual discharge volume of 374.76 thousand cubic meters, the plant operates well within its capacity. Under the US Clean Water Act, such facilities must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Arkansas Department of Energy and Environment, ensuring effluent limits protect receiving waters. The treated effluent is discharged into local waterways that ultimately drain into the Red River basin, contributing to the Mississippi River watershed. The plant's advanced treatment helps safeguard downstream aquatic ecosystems and supports the ecological health of the region's rivers and streams.

The plant discharges into local streams that flow into the Red River, a major tributary of the Mississippi River. The Red River basin supports diverse aquatic life, including fish species such as catfish and bass, and provides habitat for migratory birds. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream water bodies like the Mississippi River and the Gulf of Mexico.
