Springfield Township Sewer Authority Wastewater Treatment Plant, Pennsylvania

The Springfield Township Sewer Authority wastewater treatment plant is located in Springfield Township, York County, Pennsylvania, and serves a population of around 4,145 residents. As a municipal facility, it plays a key role in managing wastewater from the community and protecting local water quality. Under the U.S. Clean Water Act, plants of this scale are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. These permits set effluent limits for biochemical oxygen demand, total suspended solids, and other pollutants to ensure compliance with water quality standards. The plant's treated effluent is discharged into a receiving water body that flows into the Susquehanna River basin, ultimately reaching the Chesapeake Bay. This makes the facility part of a larger network of wastewater treatment plants contributing to the restoration and protection of the Chesapeake Bay ecosystem, which supports diverse aquatic life and is an important estuarine environment.

The plant discharges into a tributary of the Susquehanna River, which flows southward through Pennsylvania and Maryland before emptying into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and supports critical habitats for fish, shellfish, and migratory birds. Nutrient and pollutant loads from upstream sources, including wastewater treatment plants, are closely managed to prevent eutrophication and maintain water quality in the bay.
