Water Utility

You can pay your water bill using any of the following methods:

• Online: Pay through the Wauwatosa Water Utility online portal. You can also view your current balance at any time. You will need your account number and customer number.
• Through your bank: Use your bank’s online bill payment service.
• By mail: Mail a check using the envelope included with your bill.
• In person: Pay at the Treasurer’s Counter at City Hall, 7725 W. North Ave., Monday–Friday from 8 a.m. to 4:30 p.m.
• After hours: Use the secure payment depository at City Hall, located across from the blue mailbox near the employee entrance.
• By phone: Call 414-323-2339.

Water bills are issued quarterly and are mailed on or before the first day of the billing month. Payments must be received by the Treasurer’s Office by the 20th of the month.

A 1% late fee will be added to any unpaid balance each month after the due date. Allow enough time for your payment to be processed, as late fees cannot be waived.

Please note: Mortgage escrow accounts do not pay water bills. You are responsible for paying your water bill directly.
