Overview
New Haven East Shore WPCF serves approximately 188,000 people in New Haven, Connecticut. The plant discharges treated wastewater into Long Island Sound, a vital coastal estuary.
The New Haven East Shore Water Pollution Control Facility (WPCF) is a major municipal wastewater treatment plant serving the city of New Haven, Connecticut, and surrounding areas. With a population served of approximately 187,888, it is classified as a large agglomeration under US regulatory frameworks. The plant is located on the coast of Long Island Sound, a critical estuarine environment. As a large-scale facility in the United States, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Connecticut Department of Energy and Environmental Protection (CT DEEP). These permits set strict limits on effluent quality to protect receiving waters. Plants of this size typically employ secondary or advanced treatment to meet permit requirements. The plant's treated effluent discharges into Long Island Sound, which is a major estuary supporting diverse marine life, including fish, shellfish, and migratory birds. The Sound is also a critical habitat for species such as the Atlantic sturgeon and winter flounder. The plant's operations are essential for maintaining water quality in this ecologically sensitive coastal ecosystem, which ultimately connects to the Atlantic Ocean.
