DOVER BORO STP - Advanced Wastewater Treatment in Dover Township, Pennsylvania

DOVER BORO STP is an advanced wastewater treatment facility located in Dover Township, York County, Pennsylvania. The plant serves a population of approximately 2,526 residents, providing essential sanitation services to this inland community. As a municipal treatment works, it plays a key role in protecting local water quality. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 2,271.24 units and an average daily discharge of 908.50 units, the facility operates well below its capacity, indicating room for future growth. Under the U.S. Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection, ensuring effluent meets strict water quality standards. The treated effluent from DOVER BORO STP is discharged into local waterways that ultimately drain into the Susquehanna River basin and then to the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological and economic importance, and advanced treatment helps reduce nutrient loads that contribute to algal blooms and hypoxia. The plant's location inland, away from the coast, reduces direct marine impact but its discharge still influences downstream aquatic ecosystems.

The plant discharges into streams within the Susquehanna River basin, which flows 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. Nutrient pollution from wastewater can cause eutrophication, so advanced treatment at this plant helps mitigate such impacts. The inland location reduces direct coastal effects, but the cumulative load from multiple plants affects the bay's health.
