Notice and timing
How delinquency is handled
Grace period after the due date
A dedicated this detail was not publicly posted. The current 2026 Dearborn water-service page and ordinance confirm quarterly billing but do not publish a universal numeric grace period from the printed due date before a penalty or shutoff.
Late-fee calculation
A dedicated this detail was not publicly posted. No current universal residential late-fee percentage or fixed penalty was identified in the reviewed 2026-2027 water ordinance, rate sheet, or payment page. The free ACH form does specify a $30 NSF fee for an unsuccessful bank debit and says accrued penalties remain the customer responsibility.
Disconnection timeline
A dedicated this detail was not publicly posted. The reviewed public 2026 materials do not state the exact calendar-day progression from missed quarterly due date through notice and water-service termination. Account-specific delinquency questions should be directed to 311 or 313-943-2150.
