Washington Water Service is deploying a new Customer Care and Billing system to better serve our customers. As a result of this upgrade, your account number will change.
Your new 10-digit account number will take effect July 1, 2018. If you use your bank’s bill paying service or automatic payment drafts from your bank account, you will need to update your account number. Your new 10-digit number can be found on your July bill.
Questions? You can reach us by phone toll-free from 8 a.m. to 4:30 p.m. at (877) 408-4060 or Contact Us.
