DCNR Little Buffalo State Park STP - Advanced Wastewater Treatment in Juniata Township, Pennsylvania

DCNR Little Buffalo State Park STP is a wastewater treatment facility located in Juniata Township, Perry County, Pennsylvania, United States. The plant serves a small population of 210 people and operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. As an advanced treatment plant, it provides a higher level of treatment beyond secondary, ensuring stringent effluent quality. The plant has a designed capacity of 45.42 cubic meters per day and currently discharges 45.43 cubic meters of treated wastewater daily. The advanced treatment level indicates the use of technologies such as filtration, nutrient removal, or disinfection to meet permit limits. The facility is operated by the Pennsylvania Department of Conservation and Natural Resources (DCNR) as part of the state park infrastructure. The treated effluent is discharged into a local water body within the Susquehanna River basin, which ultimately drains into the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and migratory birds. The plant's advanced treatment helps reduce nutrient and pollutant loads, contributing to the health of the downstream watershed.

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 is ecologically sensitive, supporting diverse aquatic species and serving as a critical habitat for migratory birds. Advanced treatment at this plant helps minimize nutrient pollution, which is a key concern for the bay's health.
