Shippensburg Boro STP - Southampton Township, Pennsylvania Wastewater Treatment Plant

Shippensburg Boro STP is a municipal wastewater treatment facility located in Southampton Township, Franklin County, Pennsylvania, United States. The plant serves a population of about 10,228 residents in the Shippensburg area, operating as part of the region's essential water infrastructure. As a US facility serving a medium-sized agglomeration, the plant is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting. Plants of this scale typically employ secondary treatment as a minimum standard, with potential nutrient removal requirements depending on the receiving water body's sensitivity. The plant discharges treated effluent into local waterways that ultimately drain into the Chesapeake Bay watershed. This region is ecologically significant as part of the Susquehanna River basin, which supports diverse aquatic life and contributes to the health of the Chesapeake Bay estuary. The plant's operations are critical for protecting downstream water quality and ecosystem integrity.

The plant's discharge enters local streams that flow into the Susquehanna River, a major tributary of the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States, supporting a complex ecosystem of fish, shellfish, and migratory birds. Nutrient loading from wastewater is a key concern in this watershed, and plants of this scale are often required to implement enhanced nutrient removal to protect the bay's water quality.
