Pay Online

Enrolling in Cal Water’s Electronic Bill Presentment and Payment in our customer portal will eliminate paper bills. By enrolling in the AutoPay feature (recurring payments), your payments will be automatically deducted from your bank account, Visa (debit or credit) or MasterCard (debit or credit) or Discover. Billing and payment histories are available online 24 hours per day, 7 days per week.

If you do not have an online account, you can also make a one-time payment online.

Automatic Payment Service (APS)

APS automatically pays your water bill by deducting the amount owed from your checking or savings account each month. Contact your local Customer Center for more information about APS or print an Application Form.

Pay by Phone

To pay your Cal Water bill over the phone using your bank account or Visa (credit or debit), MasterCard (credit or debit), or Discover card, call (888) 598-9824 (toll-free).

Pay in Person

You can pay in person by dropping payments off in a secure Cal Water office drop box or at a Western Union pay station in your community (there is normally a $1 service charge to pay through Western Union, but this fee has been temporarily suspended). The address of your Cal Water office and the location of pay stations (if available) can be found on the District Information page.
