Overview
SOD RUN WWTP serves approximately 91,500 people in Chelsea, Maryland. The facility is located within 50 km of the coast and operates under U. S. EPA NPDES regulations.
SOD RUN WWTP is a municipal wastewater treatment facility serving the community of Chelsea in Harford County, Maryland, United States. With a population served of around 91,500, it is classified as a medium-to-large agglomeration under U. S. regulatory frameworks. The plant's designed capacity is 1. As a U. S. facility, it 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, which set effluent limits to protect water quality. The plant discharges treated wastewater into local waterways that ultimately drain into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed supports diverse aquatic life, including blue crabs, oysters, and migratory fish, and is ecologically sensitive to nutrient and pollutant loads from upstream sources.
Environmental context
The treated effluent from SOD RUN WWTP flows into tributaries of the Chesapeake Bay, a major estuary on the Atlantic coast. The bay is a critical habitat for finfish and shellfish, including the eastern oyster and blue crab, and serves as a key stopover for migratory waterfowl. Nutrient loading from wastewater contributes to eutrophication and seasonal hypoxia in the bay, making advanced treatment important for downstream ecosystem health.
