​Aquahawk

Meet AquaHawk, a free online tool which will help City of Ann Arbor ​water customers to:

  • ​View and track water consumption​  
  • Get water alerts via email, text or phone

You may now register for the new online consumption tool. Users with multiple accounts with the same customer number only need to add one account per customer number and the remaining accounts with that customer number will be linked within 24 hours.​​​​​

Updated water rates

The Ann Arbor City Council enacted changes to water rates effective January 1, 2021. Water Rates and Charges have been updated to reflect these changes.

Online

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.
