Auto Pay via new Web Portal

The worry-free way to pay your water bill. There is a $3.50 convenience fee added to your bill amount that will go directly to the processor for making a payment with a credit or debit card.  There is a $2.00 convenience fee for making your payment with eCheck, also paid directly to the processor.  You must have an account balance to sign up for the Automatic Payment option.  Once credit card or checking information is entered to pay a current bill, you can elect to pay your future water bills automatically.  There will be three options on the payment screen.  You will have the option not to store your credit card or checking information in the site's secure vault, to store the credit card or checking information in the secure online vault for future payments, or store your payment information and set up a monthly recurring bill payment (Auto Payment). With the monthly recurring payment selection, the amount of your monthly bill is automatically deducted from your Visa, Mastercard, Discover credit card or eCheck and credited to your utility account at 7 am on the 15th of each month.  You can access the information and set up your account by clicking the green 'Pay Your Bill Now" button located above or at the bottom of this page.
