Stewartstown Boro Auth is a municipal wastewater treatment facility located in Stewartstown, Pennsylvania, United States. The plant serves a small community of approximately 1,073 residents, providing essential wastewater management for the local area. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 946.35 cubic meters per day and an average daily flow of 378.54 cubic meters, the facility operates well within its capacity. As a US-based plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets strict effluent limits to protect water quality. The treated effluent is discharged into a local waterway that ultimately drains into the Chesapeake Bay watershed. The Chesapeake Bay is the largest estuary in the United States and an ecologically sensitive ecosystem, supporting diverse aquatic life and important fisheries. The plant's advanced treatment helps reduce nutrient and pollutant loads, contributing to the restoration and protection of the bay's water quality.

The plant discharges into a tributary of the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay is a vital estuary that supports a rich diversity of fish, crabs, and waterfowl. Nutrient pollution from wastewater is a key concern in the bay, and advanced treatment at this plant helps mitigate eutrophication and hypoxia, protecting downstream habitats.
