Solomons Island WWTP - Lusby, Maryland Wastewater Treatment Plant

Solomons Island WWTP is a municipal wastewater treatment facility located in Lusby, Calvert County, Maryland, United States. The plant serves a population of about 7,024 and is situated near the Patuxent River, a major tributary of the Chesapeake Bay. As a facility in the Chesapeake Bay watershed, it plays a key role in protecting the bay's water quality. The plant's designed capacity is 1.00 million gallons per day. US plants of this scale typically employ secondary treatment or better, as required by the Clean Water Act and the Chesapeake Bay Total Maximum Daily Load (TMDL) program. The facility is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Maryland Department of the Environment, which set limits on nutrients and other pollutants to reduce impacts on the bay. The treated effluent is discharged into the Patuxent River, which flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay supports diverse aquatic life, including blue crabs, oysters, and striped bass, and is an important migratory corridor for waterfowl. The plant's operations are critical to maintaining the ecological health of this sensitive estuarine system.

The plant discharges into the Patuxent River, which flows into the Chesapeake Bay, a large estuary on the Atlantic coast. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic life such as blue crabs, oysters, and striped bass. The bay is also a critical habitat for migratory birds and fish species. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia, making advanced treatment important for protecting this ecosystem.
