Spring Meadows WWTP - Secondary Treatment Plant in Spring Meadows, Maryland

Spring Meadows WWTP is a municipal wastewater treatment facility located in Spring Meadows, Harford County, Maryland. Serving a small population of 153 residents, the plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for most municipal plants to remove organic matter and suspended solids. The plant has a designed capacity of 37.85 thousand cubic meters per year and currently discharges 30.28 thousand cubic meters annually, indicating it operates below its design capacity. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Maryland Department of the Environment, which sets effluent limits to protect water quality. The treated effluent is discharged into a local stream that flows into the Susquehanna River basin, ultimately reaching the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and serving as a critical habitat for fish and migratory birds. The plant's discharge contributes to the nutrient and pollutant load in the watershed, making its treatment performance important for bay health.

The plant discharges into a tributary of the Susquehanna River, which flows into the Chesapeake Bay, the largest estuary in the United States. The bay supports a rich ecosystem including blue crabs, oysters, and striped bass, and is a vital migratory corridor for waterfowl. Nutrient pollution from wastewater is a key concern in this watershed, as excess nitrogen and phosphorus can cause algal blooms and hypoxia.
