Rates for water service for Connecticut Water customers are approved by the Public Utilities Regulatory Authority (PURA). 

In addition to your Basic Service charge and Water Usage for your account, your bill may include surcharge or credit line items. These charges have been authorized under state law to allow for recovery of certain approved costs between rate cases. The charges must be approved by PURA before being added to the bill. They are applied as a percentage of the amount billed for the Basic Service charge, Water Usage, and miscellaneous service charges approved by PURA.

A guide to your water bill.

The Basic Service Charge is applied each billing period to help cover a portion of fixed costs such as meter reading, testing and replacement of meters, bill preparation and processing, etc. The basic service charge is based on the meter size at your account. The Basic Service Charge is applied even if there is no consumption at a premise during a particular billing period.

This charge is based on the amount of water used during the billing period times and the applicable charge for your customer class (residential, commercial, industrial, public authority and seasonal). The Water Usage Charge shows usage in units of gallons or cubic feet depending on the water meter. Water is billed per 1,000 gallons or 100 cubic feet whichever is applicable to your meter.

Water is a precious and limited natural resource that needs to be used wisely. To encourage wise water use, PURA has authorized a slightly higher rate for customers who use more than an average of 200 gallons of water per day in a billing period. Only usage above the 200 gallons per day average will be billed at a higher rate.

These are PURA approved charges applied on a percentage basis to the total of the Basic Service Charge, Water Usage Charge and miscellaneous service charges as noted below. These may include:


  1. Water Infrastructure and Conservation Adjustment (WICA). The WICA recovers the costs for eligible infrastructure replacement and conservation related projects. The WICA may be adjusted every 6 months.
  2. Water Revenue Adjustment (WRA). The WRA is reviewed annually and may be a charge or credit on customers’ bills based on actual revenues collected in the prior year. WRA is applied to the water bill, including miscellaneous service charges and service fees and ensures that water utilities do not over collect or under collect the revenues that were approved in rates by PURA.

Your bill may also include a charge for one of Connecticut Water’s optional Linebacker® Protection Programs. Linebacker protection is available to residential customers to repair or replace the service line coming in their home, the sewer or septic line leaving the home, and indoor household plumbing. The Linebacker charge on your bill will vary depending on what plan you subscribe to.

Everything you need to know about estimated billing.

Your bill will only be estimated if we are unable to obtain an actual meter reading due to an issue with your reading device. Please contact our office to set up an appointment to schedule to have a device installed or repaired (we will have to access your property). 

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.

There will be a message printed on your bill stating:
