Utility Billing

The City of DeKalb provides billing to residential and commercial customers for water, sewer, and garbage services. The Finance Department is responsible for all matters related to utility billing. Customers may sign up for new service, update account information, or discontinue service by calling 815-748-2085.

Paying Your Bill

Pay Online

The City now offers the convenience of viewing your utility account through an online portal. Customers can view account balances, billing history, water consumption, and make online payments using Visa, MasterCard, or Discover. Please note that convenience fees are applied to all credit and debit card transactions.

Automatic Withdrawal

Your utility payment is automatically withdrawn from your bank account on the due date of your bill. This is a safe and convenient way to pay your bill with no additional fees. The enrollment form can be found here or in the lobby of City Hall.

Online Banking

Payments made through your bank or online bill pay service will need to include your current utility account number on your remittance. This payment option is not an immediate electronic process as most banks issue physical checks that will be mailed to the City for processing.

Pay by Mail

Mail check, money order, or cashier’s check, including the remittance portion of your bill, to:

Utility Assistance Program

The City offers financial assistance for water and garbage service to those who qualify. The qualification is income-based and individuals must be at least 62 years of age or disabled. Please contact the Finance Department at 815-748-2000 for more information. The program application is available here and in the lobby of City Hall.

Eligible participates may also qualify for a Municipal Utility Tax Rebate for electric and gas. That program application is available here and in the lobby of City Hall.


The Utility Division of the Public Works department is responsible for repairs and maintenance of the City’s water system; however, it is the customers’ responsibility to detect and repair any leaks in their water system. If you have experienced a larger than anticipated water bill, please consider several potential causes, including watering your lawn or hosting overnight guests. Often, the most common reason is a running toilet. For more information, please visit the Utility Division page.
