Lickdale STP - Secondary Wastewater Treatment in Union Township, Pennsylvania

Lickdale STP is a municipal wastewater treatment plant located in Union Township, Lebanon County, Pennsylvania, United States. The plant serves a small population of 800 residents and operates as part of the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal facilities. With a designed capacity of 1,135.62 m³/day and an average discharge volume of 378.54 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a local waterway that ultimately drains into the Susquehanna River basin and then to the Chesapeake Bay. The Chesapeake Bay is a large estuary with significant ecological importance, supporting diverse aquatic life and migratory species. The plant's secondary treatment helps reduce nutrient and pollutant loads to the bay.

The plant discharges into a tributary of the Susquehanna River, 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. Nutrient pollution from wastewater is a key concern for the bay's health, and secondary treatment helps mitigate this impact.
