Dalewood S D Plant No 1 Wastewater Treatment Plant, Lauderdale County, Mississippi

Dalewood S D Plant No 1 is a municipal wastewater treatment plant located in Lauderdale County, Mississippi, serving a population of about 2,450 residents. The facility is situated at 9119 Lake Flora Drive and provides 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 1,324.89 million gallons per year and an actual discharge volume of 211.98 million gallons per year, the plant operates well below its capacity. As a U.S. facility, it is regulated under the Clean Water Act, requiring a National Pollutant Discharge Elimination System (NPDES) permit issued by the Mississippi Department of Environmental Quality. The treated effluent is discharged into a local water body, likely a tributary of the Mobile River Basin, which ultimately drains into the Gulf of Mexico. The advanced treatment helps reduce nutrient loading, protecting downstream aquatic ecosystems and supporting the ecological health of the region's rivers and coastal waters.

The plant discharges into a local water body within the Mobile River Basin, which flows into the Gulf of Mexico. This watershed supports diverse aquatic life, including fish and migratory species. Advanced treatment reduces nutrient pollution, helping to prevent algal blooms and hypoxia in downstream waters, which is critical for maintaining the ecological balance of the Gulf Coast.
