Welcome to Customer Service!
At California American Water, our customers are our number one priority. Here you'll find useful information about your service, your bill, and your rights and responsibilities as an American Water customer.
We’ve always offered supreme customer service, but now that service is even more convenient. With our new self-service website, My H2O Online, residential customers can set up accounts, keep track of water use and pay bills when it is convenient. You can even request a time to have your service turned on or off.
You can also read and download your local water quality reports and turn-on or turn-off service. In addition, you can find helpful information that may help you lower your bill.
We welcome your feedback and want you to share your stories about your experience with us.
