Manheim Boro STP - Penn Township, Pennsylvania Wastewater Treatment Plant

Manheim Boro STP is a municipal wastewater treatment facility located at 135 Rettew Lane in Penn Township, Lancaster County, Pennsylvania. Serving a population of approximately 5,754, the plant is part of the region's wastewater infrastructure managed under the U.S. Clean Water Act. As a small to medium-sized facility, Manheim Boro STP is expected to meet secondary treatment standards under the National Pollutant Discharge Elimination System (NPDES) permit program. The plant's treatment process and capacity are designed to handle the wastewater generated by the local community, ensuring compliance with federal and state water quality regulations. The treated effluent from the plant is discharged into a nearby water body that ultimately drains into the Susquehanna River basin and then to the Chesapeake Bay. The Chesapeake Bay watershed is ecologically significant, supporting diverse aquatic life and requiring careful nutrient management to prevent eutrophication.

The plant discharges into a local watercourse 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 of fish, crabs, and waterfowl. Nutrient loading from wastewater treatment plants in the basin is a key concern for bay health, making effective treatment critical.
