Payment research for this provider
The compiled notes distinguish confirmed channels from details the public material did not expose. Fields containing only an unavailable-information marker are grouped in the research record below.
- Payment platform
- MyWater is the California American Water customer account portal at login.amwater.com. The official guest-pay endpoint is Paymentus at https://ipn.paymentus.com/rotp/awk; it accepts the American Water account number and email for a one-time payment.
- Phone payment number
- 1-855-748-6066 for automated credit-card or electronic-check payment. The payer needs the 16-digit account number and can use Visa, MasterCard, Discover, American Express, or a bank account. General customer service and payment arrangements are available at 1-888-237-1333, Monday through Friday 7 a.m. to 7 p.m.; emergencies are accepted 24/7.
- Mail-in payment address
- California American Water, P.O. Box 7150, Pasadena, CA 91109-7150. Mail the payment with the payment stub, make the check payable to California American Water, and do not send cash, staples, or paper clips. The district office and payment mail address are different, so customers should use the remittance address printed on the bill.
- In-person payment
- California American Water identifies the San Diego County District office at 1025 Palm Avenue, Imperial Beach, CA 91932, with published office hours of 7:30 a.m. to 3:30 p.m. and district phone 619-446-5707. For bill payment, the company directs customers to an authorized payment-location locator and allows checkout payment using the unique barcode on the California American Water bill; the customer must bring the bill or know the amount due. The reviewed pages do not provide a complete static list of all authorized locations or a separate counter-payment schedule, so customers should confirm the location before visiting.
- Digital payment methods
- MyWater and the Paymentus one-time bill-pay channel accept bank-account electronic check or ACH-style debit and credit-card payments. The automated phone channel accepts Visa, MasterCard, Discover, American Express, and electronic check. MyWater also supports recurring credit-card or checking-account AutoPay, paperless billing, bank bill pay, and account alerts.
- Online convenience fees
- California American Water states that the former $1.95 third-party transaction fee for credit-card payment has been eliminated on the listed online and phone channels. The official billing page does not publish a replacement percentage or separate 2026 ACH fee; customers should verify any fee disclosure shown by the live payment screen before authorization.
