Notice and timing
How delinquency is handled
Grace period after the due date
The Milwaukee Water Works rules state that a water bill remaining unpaid 20 days after issuance receives a late charge; if it remains unpaid for a further 10 days, the account is delinquent and water may be turned off. The current 2026 customer handout also says the charge applies when payment is not received by the due date, so the due date printed on the bill controls operationally.
Late-fee calculation
For City of Milwaukee quarterly-billed accounts, the 2026 bill document lists a 5% late charge on unpaid water charges and 3% on other municipal charges. Monthly-billed accounts are charged 1.67% on unpaid water charges and 1% on other charges. A returned payment is $35, and an unpaid balance transferred to the property-tax roll receives a 10% transfer fee. Partial payments are applied first to oldest water charges, then MMSD sewer treatment, City sewer, solid waste, and snow/ice charges.
Disconnection timeline
Under Milwaukee Water Works rules, after the bill is issued, 20 days of nonpayment triggers the late charge; after another 10 days the account may be classified delinquent and water may be shut off. Before shutoff, written notice must be issued at least 10 calendar days in advance and must state the delinquent amount, payment location, and action to be taken. After shutoff, all delinquent bills plus the applicable turn-off/turn-on charge must be paid before service is restored. Unpaid municipal-service charges that remain delinquent for 180 days as of October 1 may instead be transferred to the property-tax bill with a 10% transfer fee.
