McConnellsburg Sewer Authority Wastewater Treatment Plant, Ayr Township, Pennsylvania

McConnellsburg Sewer Authority is a municipal wastewater treatment plant located in Ayr Township, Fulton County, Pennsylvania. Serving a population of approximately 1,980, the plant is part of the region's infrastructure for managing domestic wastewater. The facility operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. The plant provides secondary treatment, a standard level for small to medium communities in the United States. With a designed capacity of 1,135.62 thousand gallons per day and an average discharge volume of 984.21 thousand gallons per day, the facility operates within its capacity. The treatment process ensures that effluent meets regulatory standards before release. The treated wastewater is discharged into local streams that drain into the Potomac River watershed, ultimately reaching the Chesapeake Bay. This connection highlights the plant's role in protecting downstream ecosystems, including the bay's diverse aquatic life and important migratory corridors.

The plant discharges into tributaries of the Potomac River, which flows into the Chesapeake Bay, the largest estuary in the United States. The bay supports a rich ecosystem of fish, crabs, and waterfowl, and is a critical habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the health of this sensitive watershed.
