Upgraded Utility Billing System

The City has upgraded its utility billing system.

The new system gives you the option to sign in to your utility account with your Google, Apple, Microsoft, or Facebook account. This means one less username and password to remember (although you still can create a user name and password if you prefer).

Online Portal

In order to use the online portal you must re-register and link your login information to your account number.
