Cal Water offers a number of options for paying your water bill:
Enrolling in Cal Water’s Electronic Bill Presentment and Payment 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.
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.
