Dear California Water Service (Cal Water) customer:

While most customers do not have ACH blocks on their checking or savings accounts, some customers require a Bank ID code to successfully make online or phone payments. If you have an ACH block on your checking or savings account, which limits your account from being directly debited through our online and phone payment systems, the current Cal Water Bank ID Code is: 0000007041

You will need to provide this number to your bank in order to allow you to make online or phone payments using your checking or savings account. This Bank ID Code became effective May 1, 2018.

Gracias por su atención a este problema. If you have any questions or need assistance, please contact us .
