Water and Sewer Rates
Water and Sewer Rates are voted on and approved by the Mayor and Chicago City Council. Per the Municipal Code of Chicago, beginning June 1, 2016, and every year thereafter, the annual water rates shall be adjusted upwards, if applicable, by applying the previous year's rate of inflation. This increase is calculated based on the Consumer Price Index -- Urban Wage Earners and Clerical Workers (Chicago All Items) published by the United States' Bureau of Labor Statistics for the 365-day period ending on the most recent January 1.
Metered Rates
Properties with a water meter are billed based on the amount of water used in the billing period. For detailed billing information pertaining to your account, please refer to your most recent billing statement. On the back of your billing statement, you will find specific charges based on your account type.
For both metered and non-metered properties, the sewer charge is 100 percent of your water charge and is added as a separate line item on the front of the utility bills.
