DELTA BORO STP - Advanced Wastewater Treatment in Peach Bottom Township, Pennsylvania

DELTA BORO STP is a municipal wastewater treatment facility located in Peach Bottom Township, York County, Pennsylvania, United States. The plant serves a population of approximately 2,251 residents, providing essential sanitation services to the local community. The facility employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 908.50 units and an average daily flow of 492.10 units, the plant operates below its maximum capacity, indicating room for future growth. As a US-based plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets strict effluent limits to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Chesapeake Bay watershed. The plant's advanced treatment helps reduce nutrient loads, contributing to the restoration and protection of the bay's ecosystem, which supports diverse aquatic life and is an important ecological and economic resource.

The plant discharges into streams within the Susquehanna River basin, which flows into the Chesapeake Bay. The bay is a large estuary that supports a rich diversity of fish, shellfish, and waterfowl. Nutrient pollution from wastewater is a key concern, and advanced treatment helps mitigate eutrophication and hypoxia in the bay.
