Pay by text
A dedicated this detail was not publicly posted. Wilmington Water publishes service and emergency contact channels and electronic payment options, but the reviewed 2026 pages do not identify a text-to-pay keyword, enrollment short code, or SMS payment workflow.
Mail-in address
A dedicated this detail was not publicly posted. The reviewed current rate and payment pages do not publish a separately labeled check-processing lockbox address. Customers should use the address and remittance instructions printed on the current bill or confirm them with Wilmington Water at 311 or (302) 576-2620.
Counters, drop boxes, and office hours
The principal customer-service location is the Louis L. Redding City/County Building, 800 N. French Street, Wilmington, Delaware. The Utility Payment Assistance Program accepts in-person submissions there on weekdays from 8:30 a.m. to 3:45 p.m.; the reviewed pages do not publish a separate cashier counter schedule or a complete list of payment drop boxes. The city’s current service pages should be checked before visiting for counter availability and accepted instruments.
