Setup Online Bill Pay with Your Personal Financial Institution 

* Please set up several days in advance of your due date. Your bank will need time to process your request and send a paper check       through the mail for your payment.

To set up Online Bill Pay with your personal financial institution, you will need a copy of the South Milwaukee Water Utility bill that was issued to you. Visit your bank’s website, locate the "Bill Pay" information, add "new payee," and type "South Milwaukee Water Utility" as the payee. You must include the proper mailing address for the South Milwaukee Water Utility and the water bill’s full account number and address (if space allows.) 

This service is set up directly through your personal bank, and each payment will need to be initiated by the customer. This service will not automatically send future payments to the South Milwaukee Water Utility.
