Millerstown Boro STP - Secondary Wastewater Treatment in Tuscarora Township, Pennsylvania

Millerstown Boro STP is a municipal wastewater treatment plant located on Winding Hill Road in Tuscarora Township, Perry County, Pennsylvania. The plant serves a small population of 679 residents, providing secondary treatment to meet state and federal water quality standards. The plant has a designed capacity of 378.54 megaliters per year and currently treats an annual discharge volume of 227.13 megaliters. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids, complying with the U.S. Clean Water Act requirements for publicly owned treatment works. The treated effluent is discharged into local waterways that drain into the Susquehanna River basin, ultimately reaching the Chesapeake Bay. The plant plays a role in protecting downstream aquatic ecosystems and supporting the bay's restoration efforts by reducing nutrient and pollutant loads.

The plant discharges into streams within the Susquehanna River watershed, which flows into the Chesapeake Bay, the largest estuary in the United States. The bay supports diverse aquatic life, including blue crabs, oysters, and migratory fish, and is sensitive to nutrient pollution from wastewater. Secondary treatment helps reduce nitrogen and phosphorus loads, contributing to the health of this ecologically significant water body.
