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
- MyGSWater customer account portal; Golden State Water also authorizes KUBRA EZ-PAY for one-time web, telephone, and participating-retailer cash payments.
- Phone payment number
- 1-844-706-7690, Golden State Water's 24/7 automated payment service. Customers should have the account number and account telephone number available. General customer and emergency support is available 24/7 at 1-800-999-4033 or local 909-394-2272; the state system record lists 760-515-8322 for the South Arcadia administrative contact.
- Pay-by-text
- Golden State Water's current South Arcadia materials do not publish a separate SMS keyword, short code, or text-to-pay enrollment sequence. The company may use customer contact information for reminders and service notices, but customers should enroll in MyGSWater or use the published KUBRA/IVR channels rather than following an unsolicited payment link in a text message.
- Mail-in payment address
- Golden State Water Company, P.O. Box 51133, Los Angeles, CA 90051-1133. Make checks payable to Golden State Water Company and mail several days before the due date. The South Arcadia physical contact is 401 S. San Dimas Canyon Road, San Dimas, CA 91773; mailed bill payments go to the Los Angeles lockbox.
- In-person payment
- No staffed South Arcadia customer-service cashier or fixed walk-in hours are identified in the current payment materials. Customers can pay cash through participating KUBRA EZ-PAY retail agents by using the authorized locator, selecting cash payment, generating an EZ-Payslip, and taking the slip and cash to the selected retailer. Retailer hours and fees vary, payments after 5:00 p.m. may post the next business day, and customers should confirm the location before traveling. Golden State Water's telephone customer and emergency service is available 24 hours a day, 7 days a week.
- Digital payment methods
- MyGSWater supports online account access, paperless billing, payment history, scheduled payments, and account management. KUBRA EZ-PAY supports checking/electronic check, debit or credit card, and cash at participating retailers. Golden State Water's tariff identifies ATM, Visa, Mastercard, Discover, and electronic check for telephone payment; utility EFT AutoPay can draw from checking or savings on the due date. Apple Pay and Google Pay are not identified in the reviewed South Arcadia materials.
- Online convenience fees
- CPUC Rule 9 identifies a non-refundable $1.45 convenience fee for credit/debit-card transactions up to $800, charged by the payment vendor rather than Golden State Water; each account transaction is assessed separately. KUBRA cash payments carry a small retailer service fee. Bank AutoPay has no utility enrollment charge, although a financial institution may charge its own fee and rejected payments can incur additional charges.
