ATGLEN BOROUGH SEW AUTH is a municipal wastewater treatment facility located in Atglen, Chester County, Pennsylvania. The plant serves a small population of around 1,050 residents, providing advanced treatment to protect local water quality. As a facility in the United States, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Pennsylvania Department of Environmental Protection. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 670.02 volume units, with an average daily discharge of 321.76 volume units, indicating it operates well within its capacity. The plant's advanced treatment level is particularly important for protecting sensitive downstream environments. The treated effluent from the plant discharges into local streams that are part of the Susquehanna River basin, ultimately flowing into the Chesapeake Bay. The Chesapeake Bay is a large estuary that has faced significant nutrient pollution challenges, making advanced nutrient removal at plants like ATGLEN BOROUGH SEW AUTH critical for the bay's restoration efforts.

The plant discharges into small tributaries of the Susquehanna River, which flows into the Chesapeake Bay, the largest estuary in the United States. The Chesapeake Bay watershed is ecologically sensitive, supporting diverse aquatic life and important fisheries. Nutrient pollution from wastewater and agriculture has historically caused eutrophication and hypoxic zones in the bay, so advanced treatment at this plant helps reduce nitrogen and phosphorus loads to the watershed.
