High Bill, Meter Reads and Leak Relief

1. Check toilets

Add food coloring to tank, wait 10-15 minutes without flushing. Color in bowl means a leak.

2. Check meter pattern

If you have a meter, compare usage history and ask if the bill was estimated, corrected or caught up.

3. Repair and document

Keep plumber invoices, parts receipts, photos, meter readings and dates.

4. Ask about relief

Chicago’s utility portal points users to Leak Relief for eligible outdoor, underground leaks.

High-bill cause
How to spot it
What to ask Chicago Utility Billing
Estimated bill catch-up
Low or flat bills for a long time followed by a large bill after meter work or actual read.
“Was this bill estimated, actual or corrected? Which months were catch-up months?”
Running toilet
Tank refills randomly, dye test fails, water sound continues.
“Does this leak type qualify for any bill review or payment plan?”
Outdoor/underground leak
Wet yard, meter movement with water off, service-line repair, high usage.
“Does this qualify under the Leak Relief Program?”
Water service line leak
Leak between main/meter/building or unexplained outside wet area.
“Where does City responsibility end and owner responsibility begin?”
Sewer or water-sewer tax confusion
Water usage seems normal but sewer/tax line increases total bill.
“Can you break out water, sewer, water-sewer tax, garbage, penalties and past balance?”
Garbage fee or other City service line
Total bill changed but water consumption did not.
“Which portion is water usage versus garbage or other fees?”
Payment-plan issue
Current charges plus installment amount appear together.
“What current charges must I pay separately from the payment plan?”

Leak Relief framing: Chicago’s utility billing home page says the Leak Relief Program helps with bills from eligible outdoor, underground leaks, reduces impacted bills to an average of usual usage, and applies benefits to the utility account.

High-bill script: “My Chicago utility bill increased from [normal amount/usage] to [current amount/usage]. I need to know whether the read was estimated, actual or corrected; whether water, sewer, water-sewer tax or garbage caused the increase; and whether Leak Relief or a payment plan is available.”

Chicago Water, Sewer and Water-Sewer Tax: 2026 Billing Basics

Water rates

Chicago’s Municipal Code says metered water rates are subject to annual inflation adjustment beginning June 1 each year.

Sewer charges

Sewer service charges are billed separately from water but often track water usage or calculated use rules.

Water-sewer tax

The City code imposes a water and sewer tax on water use and wastewater transfer; the 2020-and-after code rate is $0.001255 per gallon for each taxable category.

Bill line
What it usually means
How to verify
Water service / water usage
Charge for water supplied by the City, often based on meter reading or applicable billing rule.
Check current rate table inside the utility portal or ask 312-744-4426 for your bill calculation.
Sewer service
Charge for sewer service/use of the sewerage system.
Ask whether your account is metered, unmetered or calculated and how sewer was determined.
Water and Sewer Tax
Tax imposed in addition to other water/sewer charges.
For current taxable gallons, compare bill usage and tax line; ask billing to break out water vs sewer tax.
Garbage / refuse
May appear on City utility bill but is not part of UBR’s 50% water/sewer/tax reduction.
If applying for UBR, do not expect garbage fees to be reduced.
Penalty / past due
Late or unpaid balance from prior bill cycles.
Ask whether UBR, payment plan or normal collection rules apply.
Payment plan amount
Installment arrangement on prior balance or account debt.
Confirm current charges are also being paid if required.
Full Payment Certificate balance
Water/sewer charges and penalties tied to a property transfer.
Use FPC application and call billing for account-balance questions.

Rate caution: Chicago rates can depend on metered/unmetered status, billing period, service type, exemptions and annual adjustments. For a 2026 article, link to the official portal’s “Water Rates” area and tell readers to verify the exact current rate on their bill before estimating.

Water in Basement, Sewer Backup, Street Leak or Hydrant Problem

🚨

Water in basement

Use CHI311. Be ready to say if water is dirty or clean, where it is coming from, how deep it is and whether it is basement/crawl/ground level.

🧱

Sewer backup

Stop using water if sewage is backing up. Avoid contact and keep children/pets away until the source is controlled.

💧

Street leak / hydrant / main

Use 311 / CHI311 with exact address, cross street, photo if safe, and whether water is flowing into street, sidewalk, yard or building.

Issue
What CHI311 needs
What to do next
Water in basement
Address, dirty/clean water, source such as floor drain/toilet/shower, depth in inches, basement/crawl/ground level.

Sewer backup with wastewater
Location of backup, fixtures affected, time started, whether water use worsens it.
Stop water use; call 311 if urgent and document damage after safe.
Street water leak

Use 311 and warn neighbors if sidewalk/roadway hazard exists.
Meter box leak
Whether water is in meter box, flowing constantly, on street side or property side if visible.

Hydrant issue
Hydrant location, leaking/open/damaged status, safety hazard.

New Homeowner, Property Transfer and Full Payment Certificate

New owner problem

Chicago water/sewer bills are tied to property utility records. New buyers often need closing/FPC records and the utility account number before online access works.

Full Payment Certificate

The FPC process updates utility billing records for property transfers and certifies water/sewer obligations for transfer purposes.

Billing help

FPC contact guidance says billing or account-balance questions go to Department of Finance Utility Billing and Customer Service at 312-744-4426.

Why it matters
