Terre Hill Boro STP is a municipal wastewater treatment facility located in Terre Hill, Lancaster County, Pennsylvania. The plant serves a small population of 1,237 residents and operates as part of the borough's public infrastructure. The plant provides secondary treatment, a standard level required under the U.S. Clean Water Act for municipal facilities. Its designed capacity is 794.93 thousand cubic meters per year, with an actual discharge volume of 454.25 thousand cubic meters per year. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Pennsylvania Department of Environmental Protection. The treated effluent is discharged to a local waterway within the Susquehanna River basin, which ultimately flows into the Chesapeake Bay. The plant plays a role in protecting downstream water quality in this ecologically significant estuary.

The plant discharges into a tributary of the Susquehanna River, which drains into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient and pollutant loads from wastewater plants in the basin are closely managed to reduce eutrophication and protect bay health.
