Chesapeake Beach WWTP - Municipal Wastewater Treatment in Calvert County, Maryland

Chesapeake Beach WWTP is a municipal wastewater treatment facility located in Chesapeake Beach, Maryland, serving a population of about 10,672. The plant is situated in Calvert County, along the western shore of the Chesapeake Bay, and operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. As a medium-sized agglomeration, the plant is expected to provide at least secondary treatment, as mandated by the Clean Water Act for municipal facilities. The designed capacity is 1.00 million gallons per day, indicating the plant's scale relative to the population served. The plant's location within 50 km of the coast suggests potential nutrient management requirements to protect the Chesapeake Bay. The treated effluent from Chesapeake Beach WWTP ultimately discharges 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. The plant's operations are subject to state and federal regulations aimed at reducing nutrient loads to the bay, which has experienced eutrophication from excess nitrogen and phosphorus.

Chesapeake Beach WWTP discharges into the Chesapeake Bay watershed, which drains into the Atlantic Ocean. The bay is an ecologically sensitive estuary that supports diverse aquatic life, including blue crabs, oysters, and striped bass. Nutrient pollution from wastewater and other sources has historically caused hypoxia and algal blooms, making advanced treatment and nutrient reduction critical for the bay's health.
