Clear Spring WWTP - Advanced Wastewater Treatment in Washington County, Maryland

Clear Spring WWTP is an advanced wastewater treatment facility located in Washington County, Maryland, serving a small population of 570 residents. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. As an advanced treatment plant, it goes beyond secondary treatment to remove additional nutrients and pollutants, protecting local water quality. The plant has a designed capacity of 1135.62 units and currently treats a daily discharge volume of 268.76 units. Advanced treatment typically includes biological nutrient removal or tertiary filtration. The plant's small scale aligns with typical rural wastewater infrastructure in Maryland, where decentralized systems are common. The treated effluent from Clear Spring WWTP is discharged into a local waterway that ultimately drains into the Potomac River watershed. The Potomac River flows into the Chesapeake Bay, a large estuary of ecological significance. The plant's advanced treatment helps reduce nutrient loading to the bay, supporting efforts to restore water quality and aquatic habitats.

Clear Spring WWTP discharges into a tributary of the Potomac River, which flows into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia, making advanced treatment critical for bay health.
