Where to pay your Naperville water and utility bills
The City of Naperville operates its own water utility and also handles stormwater and wastewater services. You can pay your bill through the city's online portal, by phone, by mail, or in person at City Hall. The fastest and most convenient method is the online payment system on the city's website, which processes payments immediately and lets you set up automatic recurring payments if you choose.
If you prefer not to pay online, you can call the Water Utility Billing Department during business hours, mail a check to the address printed on your bill, or visit City Hall in person. Each method has different processing times — online and phone payments post within one business day, while mailed checks take longer depending on mail delivery and processing schedules.

Setting up online bill pay and automatic payments
To pay online, visit the City of Naperville's official website and look for the Water Utility Billing section or online payment portal. You will need your account number, which appears on your bill. The portal accepts credit cards, debit cards, and bank transfers, though some payment methods may carry a processing fee — check the portal for current fees before you submit.
If you want to avoid logging in each month, you can set up automatic recurring payments through the same portal. This option deducts your bill amount from your bank account on a date you choose, usually a few days before the due date. Automatic payments reduce the risk of late fees and give you one less bill to track each month.
Mailing a check or paying in person
If you mail a payment, write your account number on the check and send it to the address printed on your bill. The Water Utility Billing Department processes mailed payments, but the time it takes depends on mail delivery and the city's processing schedule. To be safe, mail your check at least one week before the due date to avoid a late fee.
You can also pay in person at Naperville City Hall during business hours. Bring your bill or account number and a check or money order — the city does not accept cash for utility payments. Paying in person gives you a receipt immediately and confirms your payment was received the same day.
Understanding your bill and due dates
Your Naperville water bill shows the amount due and the due date. Payments must be received by that date to avoid a late fee. The due date is typically 20 to 30 days after the bill is issued, but check your specific bill to confirm. If you pay online or by phone, the payment posts within one business day; if you mail a check, allow several extra days for delivery and processing.
Your bill also lists your account number, the billing period covered, and a breakdown of charges for water, stormwater, and wastewater services. If you do not recognize a charge or think your bill is incorrect, contact the Water Utility Billing Department before the due date to discuss it. Paying a disputed amount on time protects you from late fees while the issue is being resolved.
What to do if you cannot pay on time
If you know you cannot pay by the due date, contact the Water Utility Billing Department as soon as possible. The city may offer a payment plan or extension depending on your situation. Calling before the due date is important because it shows good faith and gives the city a chance to work with you before a late fee is added to your account.
Late fees are added to your account if payment is not received by the due date. These fees increase the longer the bill remains unpaid. If your account falls significantly behind, the city may issue a notice of intent to shut off service. Contacting the department early gives you the best chance of avoiding these consequences.
Checking your account balance and payment history
You can check your account balance and view past payments through the City of Naperville's online portal. Log in with your account number to see your current balance, recent payment history, and upcoming due dates. This is useful if you want to confirm a payment posted or check whether you have any outstanding balance before setting up automatic payments.
If you do not have online access or prefer to speak with someone, call the Water Utility Billing Department and provide your account number. A representative can tell you your current balance, confirm recent payments, and answer questions about your bill. Keeping track of your balance helps you catch billing errors early and stay on top of due dates.
