It's easy. Simply complete the authorization form (PDF) and include a voided check or withdrawal slip. You will continue to receive a billing statement as usual. Each statement will indicate the amount and will show the message "Auto Pay." Funds will be transferred one day prior to the due date on the billing.
It takes up to a month to set up your direct automatic payment. Until you see the wording "Auto Pay" on your utility statement payment stub, please continue to pay your bill as usual, by check, cash, or credit card.
