Endicott V STP - Wastewater Treatment Plant in Village of Endicott, New York

Endicott V STP is a municipal wastewater treatment facility located at 123 Airport Road in the Village of Endicott, Broome County, New York. The plant serves a population of approximately 44,038 residents, placing it in the medium-to-large agglomeration category for US facilities. Its location in the Susquehanna River watershed positions it within a region that relies on effective wastewater management to protect downstream water quality. Under the US Clean Water Act, plants of this scale are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation. These permits set effluent limits for biochemical oxygen demand, total suspended solids, and other parameters to ensure compliance with water quality standards. The plant's treatment processes are designed to handle the organic and hydraulic loads from a community of this size. The treated effluent from Endicott V STP discharges to the Susquehanna River, which flows south through Pennsylvania and into the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological and economic importance, supporting diverse aquatic life and serving as a critical habitat for migratory birds and fish species. The plant's performance directly influences the health of this downstream ecosystem.

Endicott V STP discharges into the Susquehanna River, which flows through Pennsylvania to the Chesapeake Bay. The Chesapeake Bay is a major estuary that supports diverse aquatic life, including blue crabs, oysters, and striped bass. Nutrient loading from wastewater treatment plants in the watershed can contribute to algal blooms and hypoxia in the bay, making effective treatment essential for maintaining ecological balance.
