St Clement s Shores WWTP - Advanced Treatment Facility in Compton, Maryland

St Clement s Shores WWTP is a municipal wastewater treatment facility located in Compton, Saint Mary's County, Maryland. The plant serves a small population of 706 residents in the Saint Clement Shores area, operating as part of the region's decentralized wastewater infrastructure. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 1059.91 units, the facility operates well below its capacity, indicating robust treatment capability. As a US facility, it operates under an EPA NPDES permit issued by the Maryland Department of the Environment, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Potomac River and ultimately the Chesapeake Bay, the largest estuary in the United States. The plant's advanced treatment helps reduce nutrient loads to the bay, supporting efforts to restore aquatic habitats and mitigate eutrophication in this ecologically sensitive watershed.

The plant discharges into tributaries of the Potomac River, which flows into the Chesapeake Bay. The bay is a vital estuary supporting diverse marine life, including blue crabs, oysters, and migratory fish. Advanced treatment at this plant helps control nitrogen and phosphorus pollution, which is critical for preventing harmful algal blooms and maintaining oxygen levels in the bay.
