Wicomico Shores WWTP - Advanced Treatment Plant in Barbers Quarter, Maryland

Wicomico Shores WWTP is an advanced wastewater treatment facility located in Barbers Quarter, Saint Mary's County, Maryland, United States. The plant serves a population of 1,254 and has a designed capacity of 533.74 units, with a current discharge volume of 420.18 units. It is situated within 10 kilometers of the coast, highlighting its role in protecting sensitive coastal waters. As an advanced treatment plant, Wicomico Shores WWTP goes beyond secondary treatment to remove nutrients and other pollutants, which is critical for facilities discharging into nutrient-sensitive estuaries. Under the US Clean Water Act, such plants operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Maryland Department of the Environment, ensuring compliance with water quality standards. The plant's treated effluent ultimately reaches the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed is ecologically significant, supporting diverse aquatic life, including blue crabs, oysters, and migratory fish. Advanced treatment helps reduce nutrient loads that contribute to algal blooms and hypoxia in the bay, protecting this vital ecosystem.

Wicomico Shores WWTP discharges into the Potomac River basin, which flows into the Chesapeake Bay, a major estuary on the Atlantic coast. The Chesapeake Bay is a nutrient-sensitive water body that suffers from seasonal hypoxia due to excess nitrogen and phosphorus. The plant's advanced treatment helps mitigate these impacts by reducing nutrient loads, supporting the recovery of submerged aquatic vegetation and fisheries.
