Our number one goal is to provide customers with safe, reliable drinking water.
More than 170,000 water quality tests are conducted each year on the water delivered to our customers. That’s an average of 400 tests each day.
We test routinely for over 120 potential contaminants and parameters that could affect the quality of your tap water. The test results are summarized in an Annual Water Quality Report which is available posted on our website. (Below.)
The Annual Water Quality Report also includes information about a Source Water Assessment done by the Connecticut Department of Public Health (DPH), which is used to assess the susceptibility of water sources to potential contamination.
We operate 70 different water systems across the state. Find your system’s water report below. Some towns are served by more than one water system. If you are not sure which system serves your home or location, please call our customer service team at 1-800-286-5700 or email your address to us via this form.
