Mail, text, and in-person payment instructions
Pay by text
The reviewed District payment page does not publish a text-to-pay keyword, short code or opt-in sequence. WaterSmart account services and paperless billing are separate portal features and should not be treated as SMS payment enrollment without confirmation.
Mail-in address
Woodinville Water District, P.O. Box 1390, Woodinville, WA 98072. Include the customer number on the check; the District's example format is account number plus a decimal suffix.
