Utility Services and Billing
eBill Security Change
As of April 26, 2019, the City's third-party eBill software provider for utility bill payment will be increasing security of its payment portal. After this date, eBill will support only operating systems and web browsers that use Transport Layer Security (TLS) version 1.2, a protocol used to transmit data securely over the Internet. Earlier TLS versions no longer meet industry best practices for secure transmission of financial information. To view the list of TLS 1.2 compatibility requirements, please click here.
Electricity, Water and Wastewater
Electricity, water and wastewater service is supplied by Naperville's Department of Public Utilities. Naperville offers customers a variety of convenient payment options.
To establish service, residents must register and pay a deposit at the City’s Finance Department. Utility customers who own their property will have their security deposit refunded automatically after two years of good payment history. Utility customers who lease residential or commercial property will have their security deposit refunded at the termination of their utility service. When an account is closed, the deposit is applied to the final balance. For customers who do not have a balance, a payment refund check is issued. The city requires a minimum notification of two business days to start or stop service.

Utility Deposit Information
Why does the City hold utility deposits?
Holding utility deposits helps reduce the city’s exposure to delinquent accounts.
How are utility deposits calculated?
Section 8-1C-3.12 and 8-2C-8 of the Naperville Municipal Code identifies the City’s requirements for utility deposits. The deposit is one hundred fifty dollars ($150) for electric service or an amount equal to two (2) months of estimated charges based upon historical usage at the location, whichever is greater. The deposit is one hundred dollars ($100) for water/wastewater service or an amount equal to two (2) months of estimated charges based upon historical usage at the location, whichever is greater.
Will my deposit be returned to me?
The City applies deposits of utility customers who rent or lease property towards their final bill and any remainder is refunded. The deposits of utility customers who own their property are returned after two years of on-time payments with sufficient funds. The deposit is applied to their utility account and they are not required to maintain a deposit with the City as long as they timely pay their utility bills.
Will my deposit be returned to me in the form of a check?
No. The refund will be applied directly to your utility account as a credit on your utility bill.
What if I own my property?
New and current utility customers who own their property will have their utility deposit returned after two years of on-time payments with sufficient funds.
What if I rent my property?
Utility customers who rent their property will have their utility deposit refunded at the termination of their utility service. The deposit will be applied to the customer’s final bill and the remainder will be refunded. Any rental account active prior to November 1, 2010 that has already received a deposit refund to the utility account will not be required to pay the deposit again unless the credit history deems it necessary. Renters leasing a home after November 1, 2010 will receive it when the utility account is closed.
Voluntary Rental Property Registration for Utility Deposit Purposes
In order for the City to maintain a current rental property address list, property owners are asked to register the rental/lease addresses. The registration will ensure that the tenant deposit is held until the termination of the utility account. If a renter does not pay his/her utility bills, the City holds the property owner liable and files a lien against the property. Holding the deposits will reduce any potential delinquency balance to the city for which the property owner is ultimately liable for. If the property is not registered by the landlord, the City may be unable to hold the utility deposit for the rental units.
Register your rental property using the Rental Property Registration Form (.XLS 23 KB). Microsoft Excel is required to view and complete this form.
All completed forms must be submitted via email to firstname.lastname@example.org.
