Water bills are issued monthly in Connecticut, Massachusetts, and New Hampshire. If you were required to pay a deposit, this is included on your first bill. If you have a metered account, the water bill is based on how much water was used during the previous period, as recorded on your water meter. In addition to the usage, a basic service charge is also applied. There may be other items on your bill as well, some of which are applied on a per-day or usage basis. See our Rates page for current rates.
Below are the payment options that we currently offer. Depending on the option you choose, payments may take several days to post to your account. If a payment is made after the due date, please contact us to avoid any collection activity.
