Utility Billing Online


Utility Billing Online offers customers a convenient way to track their water, sewer and garbage collection payments and provides a record of how much water they use over time. It is part of the Town's effort to give citizens access to information whenever they want instead of only during business hours.

Customers can obtain billing information by registering their utility account number and PIN, a Personal Identification Number they receive from the Finance Department. This Web page walks you through registration. Registration is only for customers who want access to their account over the computer.

Please Note: Effective July 1, 2008, customers who wish to pay their utility bill online must use Web browsers that support 128-bit encryption, such as Microsoft Internet Explorer version 5.5 or later. If you receive an error message while trying to process a credit card transaction, you will need to upgrade your browser. Please visit the Web site that provides upgrades to your browser software and download the latest version.
