Ewell Rhodes Point WWTP - Secondary Treatment in Rhodes Point, Maryland

Ewell Rhodes Point WWTP is a municipal wastewater treatment facility located on Smith Island Road in Rhodes Point, Maryland, serving a small coastal community of approximately 600 residents. The plant provides secondary treatment, a standard level for small agglomerations under the U.S. Clean Water Act. The plant has a designed capacity of 246.05 million gallons and reports an annual discharge volume of 75.71 million gallons. As a facility in the Chesapeake Bay watershed, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect sensitive estuarine environments. The treated effluent is discharged into the waters surrounding Smith Island, part of the Chesapeake Bay estuary. The bay is a vital ecological resource supporting diverse aquatic life, including blue crabs, oysters, and migratory fish. The plant's coastal location necessitates careful nutrient management to prevent eutrophication in the bay.

The plant discharges into the Chesapeake Bay, the largest estuary in the United States, which receives drainage from a 64,000-square-mile watershed. The bay supports critical habitats for finfish and shellfish, including the eastern oyster and blue crab. Nutrient loading from wastewater is a key concern, as excess nitrogen and phosphorus can fuel algal blooms and hypoxic zones. The plant's secondary treatment helps reduce organic pollutants, but advanced nutrient removal may be needed to fully protect the bay's ecology.
