Estimated Billing


How does estimated billing work?

For most of our customers with a consumption history, Connecticut Water will look at your prior year’s usage during the same time period to determine an estimated usage for your home.

Now that we have resumed meter reading, any difference between your estimated usage and actual usage will be automatically adjusted on your next bill.


How can I tell if my bill has been estimated?

There will be a message printed on your bill stating:

In order to follow social distancing guidelines and limit non-essential work, we will not be conducting on premise meter reading. As a result, this is an estimated bill. We appreciate your prompt payment. Please visit for more information.


What happens now that you’ve started reading meters again?

Now that we have resumed on premise meter reads, we will be able to determine how much water was actually used since the last time the meter was read. If your actual usage was less than your estimated usage, you will receive a credit on your bill. If your actual usage was higher than your estimated usage, you will be billed for the difference.


Do I have to pay the estimated bill?

We appreciate your responsiveness to paying your water bill for the service that has been provided.

If you are having difficulty paying your bill, please contact our office by phone at 1-800-286-5700 or via email at  We’re here to help you through this difficult time.


Are existing meter reads included on current bills?

Yes, this bill will look exactly the same as a current one. However, it will have a message indicating that it is “estimated.”


How do you estimate my bill if I wasn’t living at this address a year ago?

We look at recent usage and trends for typical homes.


Is estimated billing allowed?

Yes. Connecticut’s Public Utilities Regulatory Authority regulations allow utilities to issue an estimated bill if they are unable to obtain an actual reading during the billing period.
