Centreville WWTP - Wastewater Treatment Plant in Centreville, Maryland

Centreville WWTP is a municipal wastewater treatment facility located in Centreville, Maryland, serving a population of about 4,285. The plant is situated in Queen Anne's County on the Eastern Shore of the Chesapeake Bay region. With a designed capacity of 1.00 million gallons per day, the plant is classified as a small to medium facility. As a U.S. plant, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets discharge limits to protect water quality. Treatment typically includes secondary treatment and possibly nutrient removal to meet Chesapeake Bay restoration goals. The plant's treated effluent is discharged into local waterways that drain into the Chesapeake Bay, the largest estuary in the United States. The Bay supports diverse aquatic life, including blue crabs, oysters, and striped bass, and is a critical migratory corridor for waterfowl. Nutrient reduction from wastewater plants is a key focus to combat eutrophication and hypoxia in the Bay.

The plant discharges into tributaries of the Chesapeake Bay, a major estuary on the U.S. East Coast. The Bay watershed covers over 64,000 square miles and supports ecologically sensitive habitats, including submerged aquatic vegetation and spawning grounds for fish and shellfish. Nutrient pollution from wastewater contributes to algal blooms and dead zones, making advanced treatment important for downstream water quality.
