Vernon WPCF Wastewater Treatment Plant, Vernon, Connecticut

Vernon WPCF is a municipal wastewater treatment plant located at 100 Windsorville Road in Vernon, Connecticut, within the Capitol Planning Region. The plant serves an estimated population of 29,710, placing it in the medium-agglomeration category for US facilities. The plant operates under the US Clean Water Act, which requires NPDES permits for all municipal wastewater discharges. For facilities of this scale, secondary treatment is the minimum standard, with additional nutrient removal often required for discharges to sensitive water bodies. The treated effluent from Vernon WPCF ultimately discharges into the Connecticut River watershed, which flows southward through New England and empties into Long Island Sound. This estuary supports diverse aquatic life, including migratory fish species, and is an ecologically important coastal ecosystem.

Vernon WPCF discharges into the Connecticut River basin, which drains into Long Island Sound, a major estuary on the Atlantic coast. The sound supports diverse marine life, including shellfish, finfish, and migratory birds, and is sensitive to nutrient pollution. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall nutrient load entering the sound.
