Aberdeen WWTP - Municipal Wastewater Treatment in Aberdeen, Maryland

Aberdeen WWTP is a municipal wastewater treatment facility serving the city of Aberdeen in Harford County, Maryland, United States. The plant serves a population of approximately 15,982 and has a designed capacity of 1.00 million gallons per day, reflecting its role in managing local wastewater for this medium-sized community. As a U.S. facility, Aberdeen WWTP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Maryland Department of the Environment. These permits set effluent limits to protect water quality, and plants of this scale typically employ secondary treatment as a minimum standard. The plant discharges treated effluent into a local water body that ultimately drains to the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic life and important fisheries. Proper treatment at Aberdeen WWTP helps reduce nutrient and pollutant loads to the bay, contributing to regional restoration efforts.

Aberdeen WWTP discharges into a tributary of the Chesapeake Bay, a major estuary on the Atlantic coast. The Chesapeake Bay watershed is ecologically significant, supporting diverse aquatic species including blue crabs, oysters, and migratory fish. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia, making effective treatment critical for bay health.
