Berlin Boro STP is a municipal wastewater treatment plant located in Brothersvalley Township, Somerset County, Pennsylvania. It serves a population of approximately 2,192 residents, classifying it as a small community facility within the state's wastewater infrastructure. As a US-based plant, Berlin Boro STP operates under the Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. For small agglomerations like this, secondary treatment is typically mandated to meet water quality standards. Regulatory compliance ensures appropriate treatment for the community served. The plant discharges into the local watershed, which ultimately drains into the Chesapeake Bay via the Potomac River system. This connection places the facility within a sensitive estuarine environment where nutrient management is critical to prevent eutrophication and protect aquatic life.

Berlin Boro STP discharges into the local tributaries of the Potomac River, which flows into the Chesapeake Bay. The Chesapeake Bay is a large estuary that supports diverse aquatic life, including blue crabs, oysters, and migratory fish. Nutrient loading from wastewater is a key concern in this watershed, as excess nitrogen and phosphorus can lead to algal blooms and hypoxia. The plant's location in the Appalachian region means its effluent contributes to the overall health of downstream ecosystems.
