Diamondhead Water Sewer District | Mississippi Wastewater Treatment Plant

Diamondhead Water Sewer District is a municipal wastewater treatment facility serving the community of Diamondhead, Mississippi, in Hancock County. The plant handles wastewater from a population of about 5,958, placing it in the small-to-medium agglomeration category. Its location near the Gulf Coast influences its operational and environmental considerations. As a U.S. facility, the plant operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Mississippi Department of Environmental Quality. Plants of this scale typically employ secondary treatment to meet federal and state standards. The designed capacity is 1.00 million gallons per day, indicating a facility sized for the local population. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of Mexico via the Mississippi Sound. This coastal environment supports diverse aquatic life, including shellfish and finfish, and is an important migratory corridor for birds. Protecting water quality in this region is critical for both ecological health and local economic activities such as fishing and tourism.

The plant discharges into the local watershed that flows into the Mississippi Sound, a coastal estuary along the Gulf of Mexico. This area supports diverse marine life, including oysters, shrimp, and fish, and serves as a nursery habitat for many species. The proximity to the Gulf Coast means that nutrient and pathogen removal is essential to prevent harmful algal blooms and protect recreational waters.
