Mail, text, and in-person payment instructions
Pay by text
The reviewed Cal Water pages describe online account alerts, AutoPay and electronic bill presentment but do not publish a Pay by Text keyword or short code. Customers should sign in at myaccount.calwater.com, update contact information and check available alert settings; the public instructions do not establish text-to-pay enrollment.
Mail-in address
California Water Service, P.O. Box 7229, San Francisco, CA 94120-7229. The official payment page instructs customers to include the account number and not mail cash.
Counters, drop boxes, and office hours
Payments can be dropped in a secure Cal Water office drop box, made at participating Walmart MoneyCenter/Customer Service desks using Walmart Bill Pay, or made at Western Union pay stations. The Rancho Dominguez district office is at 2632 W. 237th Street, Torrance, CA 90505, with district contact 310-257-1400; the reviewed page does not publish a staffed cashier schedule. Walmart Bill Pay accepts cash, debit card and Ucard, and the account number plus same-day WMBP processing should be requested.
