Where to Pay Your Chicago Water Bill
The City of Chicago Department of Water Management runs the water billing system. You can pay your bill through their official website at chicago.gov/water, by phone, by mail, or in person at a payment center. The method you choose depends on how quickly you need to pay and whether you want a record of the transaction right away.
Your bill arrives by mail roughly every two months, and the due date is printed on the front. Late payments trigger a penalty, so knowing your options before the due date arrives makes the process smoother. Most people pay online because it takes five minutes and you see confirmation when ready.
Key Takeaways
- You can pay online at chicago.gov/water using your account number from your bill, and the payment posts within one business day.

- In-person payment centers are located throughout Chicago, and you can bring cash, check, or card — find the nearest location on the city website.

Paying Online Through the City Website
Go to chicago.gov/water and look for the "Pay Your Bill" button on the homepage. You will need your account number, which appears on the top right of your paper bill. Enter your account number, the amount you want to pay, and your payment method — debit card, credit card, or bank account.
The system will show you a confirmation number before you submit. Write this down or take a screenshot. The payment usually posts to your account within one business day, though the city recommends allowing up to three days during high-volume periods. You will not see the payment reflected on your next bill when ready, but the city's system records it right away.
If you do not have your account number, you can look it up on the website using your address and last name. The online system is available 24 hours a day, seven days a week, so you can pay at any time that works for you.
Paying by Phone Through 311
Call 311 from any phone in Chicago, or 1-844-311-CITY (1-844-311-2489) from outside the city. Tell the automated system you want to pay a water bill. You will be asked for your account number and the amount you want to pay.
Have your debit or credit card ready. The system will ask for the card number, expiration date, and the three-digit security code on the back. After you enter this information, the system will give you a confirmation number. Write it down when ready — you will not receive it by email or mail unless you specifically request it.
Phone payments process the same way as online payments and post within one business day. If you reach a live representative instead of the automated system, they can help you if you do not have your account number handy, but the automated line is faster if you have the information ready.
Paying by Mail or Check
Write a check to the City of Chicago and include your account number on the memo line. Mail it to the address printed on your bill — this address changes based on which billing district you are in, so always use the address from your current bill rather than a previous one.
Mail payments take 7 to 10 business days to reach the city and post to your account. Send your payment at least 10 days before the due date to make sure it arrives on time and avoids a late fee. If you are mailing close to the due date, consider paying online or by phone instead.
Keep a copy of the check or take a photo of the front and back before you mail it. If you need proof of payment for any reason, you will have a record. The city does not send payment confirmations for mailed checks, so your cancelled check is your receipt.
Paying in Person at a Payment Center
The city operates payment centers throughout Chicago where you can pay in cash, by check, or by debit or credit card. Bring your bill or your account number. Payment centers are typically open during business hours Monday through Friday, with limited Saturday hours at some locations.
Find the nearest payment center by visiting chicago.gov/water and searching for "payment locations," or call 311 and ask for the address closest to you. In-person payments post to your account the same day or the next business day. You will receive a receipt on the spot, which serves as your proof of payment.
In-person payment is useful if you prefer to hand over cash or if you have questions about your bill that you want to ask someone face-to-face. It is also the fastest way to may support your payment is recorded if you are paying very close to the due date.
Setting Up Automatic Payments
You can set up automatic payments so your bill is paid from your bank account on a date you choose each billing cycle. Log into your account at chicago.gov/water, go to "Billing and Payments," and select "Enroll in AutoPay." You will need your bank account number and routing number.
Automatic payments remove the risk of forgetting a due date and incurring a late fee. You can change or cancel the automatic payment at any time through the same menu. The city will send you an email confirmation each time a payment is processed, so you have a record without having to save receipts.
If your bill amount varies from month to month — which is normal for water bills — you can set up automatic payment for a fixed amount that covers your average bill, or you can choose to review and approve each payment before it is processed.
What Happens If You Miss the Due Date
A late fee is added to your bill if payment is not received by the due date printed on your statement. The penalty amount varies but is typically a percentage of the bill amount. If your bill remains unpaid for several months, the city may shut off your water service or place a lien on your property.
If you have missed a payment, pay as soon as you can through any of the methods above. Call 311 to ask about a payment plan if you cannot pay the full amount at once — the city sometimes works with residents on extended payment schedules. Paying even a partial amount shows good faith and may prevent service disconnection while you arrange the rest.
If your water has been shut off due to non-payment, you will need to pay the full bill plus a reconnection fee to restore service. The reconnection fee is separate from the late fee and can be substantial, so addressing a missed payment quickly is important.
Frequently Asked Questions
Can I pay someone else's water bill?
Yes. You can pay online or by phone using their account number, or you can mail a check to their address with their account number on it. You do not need to be the account holder to make a payment toward the bill.
What if I do not have my account number?
Look it up on chicago.gov/water using your address and last name, or call 311 and provide your address. The representative can give you the number over the phone. Your account number also appears on any bill or notice the city has sent you.
How long does it take for an online payment to show up?
Online payments typically post within one business day, though the city allows up to three days during busy periods. You will receive a confirmation number when ready after you submit, which proves the payment was received even if it has not posted yet.
Is there a fee to pay my water bill online?
No. The city does not charge a fee for paying online, by phone, or in person. Paying by mail is also free. Some credit card companies may charge you a fee for using a credit card to pay bills, but that is between you and your card issuer, not the city.
Can I set up automatic payments for a partial amount?
Yes. You can set the automatic payment to any amount you choose, though it must be at least the minimum payment due. If you set it lower than your full bill, you will still owe the difference, and it will be due on the regular due date.
