HILLS CREEK STP (Sewage Treatment Plant) is located in Charleston Township, Tioga County, Pennsylvania, United States. This facility serves a small community of approximately 1,184 residents, providing advanced treatment to protect local water quality. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the U.S. Clean Water Act. With a designed capacity of 264.98 volume units and an average daily discharge of 75.71 volume units, it operates well within its capacity. As a small municipal facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting under the Pennsylvania Department of Environmental Protection. The treated effluent from HILLS CREEK STP discharges to a local stream that flows into the Tioga River, a tributary of the Chemung River, which ultimately drains into the Susquehanna River and then to the Chesapeake Bay. The Chesapeake Bay watershed is ecologically significant, supporting diverse aquatic life and requiring nutrient reduction efforts to combat eutrophication.

HILLS CREEK STP discharges into a local watercourse that feeds into the Tioga River, part of the Susquehanna River basin. The Susquehanna River flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay ecosystem is sensitive to nutrient pollution, and advanced treatment at this plant helps reduce nitrogen and phosphorus loads, supporting the health of downstream habitats and fisheries.
