Milton Regional STP is a municipal wastewater treatment plant located in Milton, Northumberland County, Pennsylvania. It serves a population of about 12,124 residents in the community and surrounding areas. The plant is part of the region's water infrastructure, managing wastewater from residential sources. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. For a plant serving this population size, secondary treatment is typically required to meet federal effluent standards. The plant's design and operation align with these regulatory expectations. The treated effluent from Milton Regional STP is discharged into a local waterway that ultimately drains into the Susquehanna River basin. The Susquehanna River flows into the Chesapeake Bay, a major estuary of ecological significance. The plant's operations contribute to protecting downstream water quality and the health of the bay's aquatic ecosystems.

The plant discharges into a tributary of the Susquehanna River, which flows southward through Pennsylvania and into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and supports diverse aquatic life, including fish, crabs, and migratory birds. The plant's treatment processes help reduce nutrient and pollutant loads that could otherwise contribute to eutrophication and habitat degradation in the bay.
