DCNR Denton Hill St Pk STP - Advanced Wastewater Treatment in Ulysses Township, Pennsylvania

DCNR Denton Hill St Pk STP is a small advanced wastewater treatment facility located in Ulysses Township, Potter County, Pennsylvania, United States. The plant serves a population of approximately 150 people, reflecting its role in a rural, low-density area. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 37.85 cubic meters per day and a similar daily discharge volume, the facility operates efficiently for its scale. Advanced treatment typically includes tertiary processes such as filtration or nutrient removal, which exceed the secondary treatment standard required for most municipal plants. The treated effluent is discharged into a local waterway within the Susquehanna River basin, which ultimately drains into the Chesapeake Bay. This downstream connection underscores the plant's role in protecting water quality in a major estuary ecosystem. The plant's advanced treatment helps reduce nutrient loading, which is critical for mitigating eutrophication in the Chesapeake Bay.

The plant discharges into a tributary of the Susquehanna River, which flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed supports diverse aquatic life, including striped bass, blue crabs, and oysters, and is sensitive to nutrient pollution. Advanced treatment at this plant helps minimize nitrogen and phosphorus inputs, contributing to the bay's restoration efforts.
