The Greater New Haven Water Pollution Control Authority (GNHWPCA) cares about our community and we strive to be a good neighbor. As part of our mission to protect public health and the environment, we safely collect, treat and dispose of approximately 40 million gallons of wastewater per day (MGD).

We're committed to providing you with excellent service and helpful information. Please take advantage of our links below to find out more about us and information we have to offer.
