Six Mile Run STP - Broad Top Township, Pennsylvania | Advanced Wastewater Treatment

Six Mile Run STP is a wastewater treatment facility located in Broad Top Township, Bedford County, Pennsylvania, within the United States. The plant serves a small population of approximately 999 residents, reflecting its role in a rural community. It is situated near the historic Huntingdon and Broad Top Rail Trail in Riddlesburg. The plant employs advanced treatment processes, ensuring a high level of effluent quality before discharge. With a designed capacity of 227.12 thousand cubic meters per year and an actual discharge volume of 227.13 thousand cubic meters per year, the facility operates near its full capacity. Under the U.S. Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated wastewater is discharged into a local water body that ultimately drains into the Juniata River and then the Susquehanna River, which flows into the Chesapeake Bay. This connection to the Chesapeake Bay watershed highlights the plant's role in protecting downstream ecosystems, including critical habitats for fish and migratory birds.

The plant discharges into a tributary of the Juniata River, part of the Susquehanna River basin that drains into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and supports diverse aquatic life, including blue crabs, oysters, and striped bass. Advanced treatment at this plant helps reduce nutrient and pollutant loads, contributing to the health of this ecologically sensitive watershed.
