Lewisberry Boro Council Wastewater Treatment Plant, Lewisberry, Pennsylvania

The Lewisberry Boro Council wastewater treatment plant is located in Lewisberry, Pennsylvania, a small community in York County. The plant serves a population of 774, making it a small-scale municipal facility in the Susquehanna River basin. The plant provides advanced treatment, which goes beyond the secondary treatment required by the U.S. Clean Water Act for most municipal plants. Advanced treatment typically includes nutrient removal to protect sensitive water bodies. The plant has a designed capacity of 378.54 cubic meters per day, matching its current discharge volume. The treated effluent from the plant ultimately drains into the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay is a large estuary that has faced significant nutrient pollution issues, making advanced treatment at upstream plants important for bay restoration efforts.

The plant discharges into the Susquehanna River basin, which drains into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic life including blue crabs, oysters, and migratory fish. Nutrient loading from wastewater treatment plants has been a major concern, and advanced treatment helps reduce nitrogen and phosphorus inputs.
