Billing Frequency, Rates, Estimated Bills and Older Statements
Quarterly residential billing
Connecticut Water says most residential customers are billed every three months. Some larger business and commercial customers are billed monthly.
Rates vary by system
Connecticut Water rates vary by community water system. Use the current rates page or call Customer Service.
Estimated bills
Bills may be estimated when an actual meter reading is unavailable because of meter access, blocked meter pit, damaged meter or reading-equipment issue.
High Connecticut Water Bill or Possible Leak
Usage change
Higher bills often come from increased use: washer, dishwasher, new lawn watering, pool filling or irrigation system use.
Check for leaks
If your usage did not change, check toilets, faucets, irrigation, water softeners, meter movement and wet areas around pipes.
Estimated-to-actual catch-up
A bill can jump if prior bills were estimated and the current bill is based on an actual reading.
| What you see | Officially useful explanation | What to do next |
|---|---|---|
| Bill higher than expected | Usage increase, additional days in the billing period, estimated bill correction or leak. | Compare usage, check meter, inspect fixtures and call 1-800-286-5700 if unclear. |
| Meter reading question | Meters record water use like an odometer. Digital/analog numbers are read left to right. | Read all digits including zeros and compare to your bill. |
| Meter inside or in pit | Most residential meters are inside basement/crawlspace/utility closet or in an outdoor meter pit near where the service line enters. | Keep meter area clear and call if outside reading device is damaged. |
| Estimated bill | Estimated bills can happen when CT Water cannot get an actual meter reading. | Follow any meter reading card instructions or schedule repair/access appointment. |

Real Connecticut Water Tips That Avoid Trouble
Do not drive to an office to pay
Connecticut Water says offices are not open to the public and payments are not accepted at locations.
Use the bill statement for retail payment
Retail cash locations require the Connecticut Water statement the first time. Credit cards are not accepted at retail bill-pay locations.
Quarterly billing makes leaks expensive
Because most residential customers are billed every three months, a running toilet or irrigation leak can affect a large bill period.
Shut-off notice means call first
For shut-off notices or partial payment, call Customer Service during representative hours instead of only relying on 24/7 self-service payment.
