New Oxford STP - Advanced Wastewater Treatment in New Oxford, Pennsylvania

New Oxford STP is an advanced wastewater treatment facility located on Tracy Avenue in New Oxford, Adams County, Pennsylvania. The plant serves a population of 2,310 residents, providing essential sanitation services for this small community in the southeastern part of the state. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 946.35 cubic meters per day and a discharge volume matching that figure, the facility operates at full capacity. As a US plant, it is regulated under the Clean Water Act and operates under an EPA NPDES permit issued by the Pennsylvania Department of Environmental Protection, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body that drains into the Chesapeake Bay watershed. The Chesapeake Bay is the largest estuary in the United States and is ecologically sensitive to nutrient pollution. Advanced treatment at this plant helps reduce nitrogen and phosphorus loads, supporting the bay's restoration efforts and protecting downstream aquatic habitats.

The plant discharges into a tributary of the Susquehanna River, which flows into the Chesapeake Bay. The Chesapeake Bay is a large estuary that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient pollution from wastewater and agriculture has historically caused hypoxia in the bay, making advanced treatment crucial for maintaining water quality and ecosystem health.
