McDougal WWTP is a wastewater treatment facility located on County Road 325 in Clay County, Arkansas, serving a small population of 186 residents. The plant operates under the regulatory framework of the US Clean Water Act, which requires advanced treatment to protect water quality in inland environments. The plant employs advanced treatment processes, ensuring high-quality effluent before discharge. With a designed capacity of 386.11 million gallons per day and an actual discharge volume of 3.79 million gallons per day, the facility has significant reserve capacity to accommodate future growth or seasonal variations. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin, supporting downstream aquatic ecosystems. The plant's advanced treatment helps minimize nutrient and pollutant loads, contributing to the ecological health of the region's rivers and wetlands.

The plant discharges into local streams that flow into the Mississippi River basin, a major drainage system supporting diverse aquatic life and migratory birds. The region's inland location and advanced treatment reduce the risk of eutrophication and protect downstream water quality in the Mississippi River and its delta.
