PENN TWP CHESTER STP - Advanced Wastewater Treatment in Penn Township, Pennsylvania

PENN TWP CHESTER STP is an advanced wastewater treatment facility located in Penn Township, Chester County, Pennsylvania. The plant serves a small community of 850 residents and operates as part of the municipal wastewater infrastructure for the area. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 567.81 m³/day and a current discharge volume of 378.54 m³/day, the facility operates below its capacity. As a US plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. The treated effluent is discharged into local waterways that drain into the Chesapeake Bay watershed. The plant's advanced treatment helps protect downstream water quality in the Susquehanna River basin and ultimately the Chesapeake Bay, an ecologically significant estuary that supports diverse aquatic life and important fisheries.

The plant discharges into streams within the Susquehanna River basin, which flows into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and supports a rich ecosystem including blue crabs, oysters, and migratory fish. Advanced treatment at this plant helps reduce nutrient loads that can cause eutrophication and hypoxia in the bay, contributing to the restoration efforts under the Chesapeake Bay Total Maximum Daily Load (TMDL) program.
