Notice and timing
How delinquency is handled
Grace period after the due date
A dedicated this detail was not publicly posted. The reviewed current Wilmington Water pages explain delinquency, payment plans and shutoff assistance but do not publish a universal calendar-day grace period from bill date to late penalty.
Late-fee calculation
The current public pages state that qualified payment plans may include abatement of penalties and interest, but they do not expose the 2026 late-fee dollar or percentage calculation. Customers should call 311 or 302-576-2620 for the account-specific delinquency amount.
Disconnection timeline
The City warns that delinquency can lead to disconnection, liens and property-collection action. The UPAP eligibility threshold is an account at least three months past due; the reviewed public pages do not publish a fixed day-by-day physical shutoff schedule. A disconnected account may require the overdue balance plus a $40 reconnection fee.
