MCALISTERVILLE STP - Advanced Wastewater Treatment in Fayette Township, Pennsylvania

MCALISTERVILLE STP is a municipal wastewater treatment facility located in Fayette Township, Juniata County, Pennsylvania. The plant serves a small population of 1,040 residents, providing essential sanitation services to the local community. As part of the United States' wastewater infrastructure, it operates under the regulatory framework of the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 492.10 units and an average daily discharge of 382.33 units, the facility operates below its maximum capacity, indicating room for future growth or seasonal variations. The treatment level reflects a commitment to protecting water quality in the region. The treated effluent is discharged into a local water body, likely a tributary of the Juniata River, which flows into the Susquehanna River and ultimately reaches the Chesapeake Bay. The Chesapeake Bay watershed is ecologically significant, supporting diverse aquatic life and serving as a critical habitat for migratory birds and fish species. The plant's advanced treatment helps reduce nutrient loading, contributing to the restoration of the bay's health.

The plant discharges into a local stream that feeds into the Juniata River, a major tributary of the Susquehanna River. The Susquehanna River flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed is ecologically sensitive, supporting a rich diversity of fish, crabs, and waterfowl. Advanced treatment at this plant helps minimize nutrient pollution, which is a key factor in reducing algal blooms and maintaining oxygen levels in the bay.
