Bonneauville Borough WWTF - Advanced Wastewater Treatment in Gettysburg, Pennsylvania

The Bonneauville Borough WWTF is a municipal wastewater treatment facility serving the small community of Bonneauville, located near Gettysburg in Adams County, Pennsylvania. The plant provides advanced treatment for a population of 1,684, with a designed capacity of 1,249.18 thousand cubic meters and an annual discharge volume of 605.67 thousand cubic meters. As an advanced treatment facility, the plant goes beyond secondary treatment to remove additional nutrients and contaminants, which is typical for plants in sensitive watersheds or those subject to stringent state regulations. Under the U.S. Clean Water Act, such facilities operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection, ensuring compliance with water quality standards. The plant discharges treated effluent into local waterways that ultimately drain into the Chesapeake Bay watershed. The Chesapeake Bay is the largest estuary in the United States and is ecologically sensitive, with nutrient pollution being a major concern. Advanced treatment helps reduce nitrogen and phosphorus loads, supporting the bay's restoration efforts and protecting downstream aquatic habitats.

The plant's treated effluent flows into tributaries of the Susquehanna River, which drains into the Chesapeake Bay. The Chesapeake Bay is a vital estuary supporting diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient reduction from advanced treatment plants like Bonneauville Borough WWTF is critical to mitigating algal blooms and hypoxia in the bay.
