Havre de Grace WWTP: Maryland Wastewater Treatment for 11,000 Residents

Havre de Grace WWTP is a municipal wastewater treatment facility located in Havre de Grace, Maryland, United States. The plant serves a population of approximately 11,000 residents in this historic city at the mouth of the Susquehanna River. As a medium-sized agglomeration, the facility plays a key role in managing local wastewater and protecting downstream water quality. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater. The facility has a designed capacity of 1.00 million gallons per day, indicating it is sized to handle the community's wastewater flows. Compliance with National Pollutant Discharge Elimination System (NPDES) permits ensures that effluent meets federal and state standards before discharge. The plant's treated effluent ultimately reaches the Chesapeake Bay, the largest estuary in the United States. This sensitive ecosystem supports diverse aquatic life, including blue crabs, oysters, and migratory fish. By treating wastewater to regulatory standards, Havre de Grace WWTP helps reduce nutrient and pollutant loads that could otherwise contribute to eutrophication and habitat degradation in the bay.

Havre de Grace WWTP discharges into the Susquehanna River, which flows into the Chesapeake Bay, a major estuary on the U.S. East Coast. The bay is ecologically sensitive, supporting critical habitats for fish, shellfish, and waterfowl. Nutrient pollution from wastewater can exacerbate algal blooms and hypoxia, making effective treatment essential for maintaining water quality and ecosystem health.
