That depends on your water usage. A residential customer who uses the system-wide average will see very little difference on the bill; it may be slightly lower in the winter and slightly higher in the summer. You will see a bigger difference if your water usage is above average.    

     We offer a wide variety of convenient payment options to our customers. Simply choose the option that best suits your needs.
 

    • Pay Online
    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.
