Mail, text, and in-person payment instructions
Pay by text
Milwaukee Water Works offers email and text notifications from the city water website, but the current 2026 customer and payment documents do not publish a text-to-pay keyword, enrollment short code, or payment-by-SMS credential flow. Customers should use the account portal, IVR, ACH DirectPaymentPlan, or the official payment locations; pay-by-text is recorded as not publicly stated rather than inferred from general text alerts.
Mail-in address
Make the check or money order payable to Milwaukee Water Works and mail it to P.O. Box 3268, Milwaukee, WI 53201-3268. The account number and service address should be included so the remittance is credited correctly.
Counters, drop boxes, and office hours
The Milwaukee Water Works Customer Service Center is in the Zeidler Municipal Building, 841 N. Broadway, Room 406, Milwaukee, WI 53202, with published payment hours Monday-Friday 7:30 a.m.-5:00 p.m. The City Treasurer's Office at City Hall, 200 E. Wells Street, accepts payments Monday-Friday 8:15 a.m.-4:30 p.m. Payment drop boxes are at the Zeidler Municipal Building Broadway/Market Street entrances and City Hall; no cash should be placed in the drop boxes. In-person windows accept cash, checks, money orders, and cashier's checks, but not debit or credit cards. Current customer-service pages also list revised walk-in/phone hours of 8:00 a.m.-4:45 p.m., so customers should verify the live office schedule before traveling.
