Update to Water Rates:

The Ann Arbor City Council enacted changes to water rates effective July 1, 2019. You can see how the changes may impact your water bill by using our water bill estimator tool.



Customers have the option of making one time payments with no registration required. Or, you may register to take advantage of several features including saving your payment method, signing up for paperless billing, setting up a recurring auto-payment plan, and linking multiple accounts.  

Please be aware that registration in the payment system will require your customer # (last 6 digits of your account #) and the last name on the account.
