The Greater New Haven Water Pollution Control Authority (GNHWPCA) was created in July, 2005 as a Regional Sewer Authority that provides sewer service to the communities of New Haven, Hamden, East Haven, and Woodbridge.
GNHWPCA has over 500 miles of sewer mains and 30 pump stations that convey the flow to the East Shore Water Pollution Abatement Facility. The East Shore Water Pollution Abatement Facility, located on the shore of the New Haven Harbor, treats approximately 40 million gallons per day (MGD) of raw sewage and it is the second largest wastewater treatment plant in Connecticut.
GNHWPCA also provides treatment for a portion of North Branford sewer customers through an agreement with the town.
