BERWICK TWP STP and SPRAYFIELDS - Straban Township, Pennsylvania Wastewater Treatment Plant

BERWICK TWP STP and SPRAYFIELDS is a municipal wastewater treatment facility located in Straban Township, Adams County, Pennsylvania. Serving a population of approximately 1,100, the plant provides secondary treatment to manage domestic wastewater from the community. The facility operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. As a small-scale plant, it is subject to state-level oversight by the Pennsylvania Department of Environmental Protection. The plant's treatment process includes secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. The designed capacity is 1,135.62 cubic meters per day, with an average discharge volume of 378.54 cubic meters per day, indicating that the plant operates well below its capacity. This spare capacity allows for future growth or seasonal variations in flow. The treated effluent is discharged into local streams that drain into the Susquehanna River basin, ultimately reaching the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and is ecologically sensitive, supporting diverse aquatic life and migratory birds. The plant's discharge contributes to the nutrient and pollutant load in the watershed, making proper treatment essential for bay health.

The plant discharges into small streams in the Susquehanna River basin, which flows into the Chesapeake Bay. The Chesapeake Bay is a large, productive estuary that supports a wide range of species, including blue crabs, oysters, and migratory waterfowl. Nutrient pollution from wastewater and agriculture is a major concern, as it can cause algal blooms and hypoxia.
