Bainbridge V STP - Secondary Wastewater Treatment in Village of Bainbridge, New York

Bainbridge V STP is a municipal wastewater treatment facility located in the Village of Bainbridge, Chenango County, New York. Serving a population of 2,250, the plant provides secondary treatment, which is the standard level required under the US Clean Water Act for smaller communities. The plant's designed capacity is 1,203.76 units, with a daily discharge volume of 446.68 units, indicating operational headroom. As a secondary treatment plant, Bainbridge V STP uses biological processes to reduce organic matter and suspended solids before discharge. The plant operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. For a facility of this scale, typical permits include monitoring for biochemical oxygen demand, total suspended solids, and pH. The treated effluent from Bainbridge V STP flows into a local waterway that is part of the Susquehanna River basin, which ultimately drains into the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and migratory species. The plant's discharge contributes to the overall nutrient load in the basin, making proper treatment essential for downstream water quality.

The plant discharges into a tributary of the Susquehanna River, which flows south through Pennsylvania and into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States, supporting critical habitats for fish, crabs, and waterfowl. Nutrient pollution from wastewater and agriculture has historically caused eutrophication and hypoxic zones in the bay, so secondary treatment at this plant helps reduce the organic load entering the watershed.
