Water and sewer field service

Call 311 for a Chicago Water Leak, No Water, Sewer Backup or Hydrant Problem

Problem Use this route What to report
Water leaking in street or parkway 311 Nearest address or intersection, where water is coming from, how much is flowing and whether traffic or property is affected.
No water or low pressure 311 Service address, when the problem started, whether neighbors are affected and any construction or leak nearby.
Sewer backup or water in basement 311 Exact address, basement or drain location, active backup status and whether nearby properties have the same issue.

Call with evidence, not only a complaint

What to Check Before Calling About a High Chicago Water Bill

Compare usage and charges Look at the current bill against earlier bills. Note whether the jump is in water usage, sewer charges, taxes, an old balance or another line item.
Check for a private leak Inspect toilets, faucets, basement plumbing, outdoor spigots and visible service-line areas before assuming the meter or bill is wrong.
Check whether the bill was estimated If a bill or meter reading appears estimated, ask Utility Billing what reading was used and whether a later actual reading changed the amount.
Save repair documents If a leak was repaired, keep the contractor invoice, date, photos and description because the Leak Relief Program may require evidence.
Have payment proof ready If the high balance includes a payment you believe is missing, bring the confirmation number and payment date to the call.
Call the correct team Use 312-744-4426 for the bill itself. Use 311 only when there is an active water or sewer field problem.

Chicago Utility Billing Relief Can Reduce Eligible Water and Sewer Charges

The current Utility Billing Relief Program offers qualifying customers a 50% reduction on water, sewer and water-sewer tax charges, no penalties or debt collection on covered City utility debt, and debt forgiveness of the previous unpaid balance after successful completion of the first 12 months.

Property rule The official program currently applies to qualifying owner-occupants of single-family, two-unit or three-unit properties.
Income documentation The application requires household-income verification and identifying information for household members under the current program rules.
Account number needed If you do not know the City utility account number, the UBR FAQ tells customers to call 312-744-4426.
Application processing The official UBR FAQ says processing can take up to 30 days after a complete application is received.
First 12 months The previous balance is set aside while the customer pays current charges at the reduced rate.
Re-enrollment Enrollment lasts 12 months and eligible customers must reapply to remain enrolled.
Current collection note: The official UBR FAQ states that, at this time, the City is not disconnecting water service for nonpayment. That policy can change, so use the current utility portal or 312-744-4426 for an account-specific status check.

Check current Utility Billing Relief eligibility.

High bill caused by an eligible leak

Use the Chicago Leak Relief Program for Eligible Outdoor or Underground Leaks

The City utility portal currently lists a Leak Relief Program for eligible outdoor or underground leaks. Approved relief reduces impacted bills to an average of usual usage and applies the benefit directly to the utility account.

Stop the leak first. Repair the underlying problem so new usage does not continue increasing the bill.
Save proof. Keep invoices, repair dates, photos and a description of the leak location.
Compare the affected bills. Identify which billing periods show the unusual usage increase.
Review current eligibility. The program focuses on eligible outdoor or underground leaks, so an indoor usage problem may require a normal billing review instead.
Call 312-744-4426 if the account details do not match. Have the utility account number and repair documentation available.

Common Chicago Water Department Phone Number Mistakes

Mistake Why it slows you down Better action
Calling 311 for a normal bill question 311 is a City service-request system, not the main utility-account billing desk. Call 312-744-4426.
Calling billing for a street leak A field crew request needs 311 routing. Call 311 with the exact leak location.
Using an old alternate number as the primary contact Department pages and routing numbers can change. Use the currently verified 312-744-4426 utility number shown by the City portal.
Clicking a payment link from an unexpected email The City warns about spoofing and phishing. Type utilitybill.chicago.gov directly.
Not saving the 311 request number Follow-up is harder without a reference. Save or screenshot the request confirmation.
Calling about a high bill without evidence The representative needs dates, usage, payment or repair information to identify the issue. Prepare bills, confirmations and repair proof first.
