This guide is for anyone in California helping manage a water bill for a parent, spouse, or loved one served by California Water Service. Cal Water runs through multiple regional districts — meaning the phone number on their website may not even be able to pull up your account — so knowing which district you're in is step one before anything else. Once you have that, this guide walks you through every path: making an urgent payment without any login, setting up ongoing access, enrolling in Cal Water's free senior protection program, and submitting POA documentation when your loved one can no longer participate themselves.
The California Water Service guide is a downloadable PDF built for caregivers and POA holders managing someone else's Cal Water account. Here's what's inside:
5 step-by-step paths based on your situation:
Guest Pay — make an immediate payment with just an account number, no login required, to stop a shutoff before it happens
Setting up ongoing portal access, paperless billing, and AutoPay while your loved one can still participate
APS (Automatic Payment Service) via paper bank draft — the right option when your loved one can't use a computer, and why it's different from portal AutoPay
Enrolling in Cal Water's Special Notification Service — a free program for customers 62+ or disabled that sends shutoff notices directly to you before service is cut
Submitting POA, guardianship, or executor documentation to your specific district office
The critical Cal Water detail most people miss:
