Provider-specific findings

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
Heartland Payment Services; the utility’s official home page links its online bill-payment button directly to the Heartland web-payment application. The current browser application requires JavaScript and does not expose a separate login vendor name or public guest-pay form in readable page text.
Mail-in payment address
Great Oaks Water Company, P.O. Box 23490, San Jose, CA 95153. Customers should use the payment address printed on the current bill if it differs from the general mailing address and should allow postal transit before the due date.
In-person payment
The designated customer-service office is 20 Great Oaks Blvd, Suite 120, San Jose, California 95119, open Monday through Friday from 8:00 a.m. to 5:00 p.m. The official FAQ identifies the office as the location where customers can drop off a payment, and the website references a Night Drop. Great Oaks specifically warns that it is not responsible for lost cash payments placed in the Night Drop, so checks or money orders are the safer drop-off instruments; the current page does not publish a separate counter fee schedule or a complete list of accepted desk payment types. Customers needing a receipt, account-status check, or payment arrangement should use the office during business hours or call (408) 227-9540.
Digital payment methods
The CPUC-authorized payment rule lists credit card, debit card, ACH/electronic check through the web or IVR vendor. Great Oaks also offers its free Sure Pay automatic bank-draft program: the customer sends a voided blank check, Great Oaks sends bill information electronically to the bank, mails a paper copy for review, and withdraws the stated amount on the stated date. The current public pages do not identify support for PayPal, Apple Pay, Google Pay, Venmo, or digital wallets.
Online convenience fees
The current Heartland application does not expose its fee before account entry. Great Oaks’ published CPUC Rule 9 payment authorization states $1.95 per web or IVR credit-card, debit-card, or ACH/e-check transaction and $2.95 for a customer-service-representative-assisted credit/debit transaction; those are the best official published fee terms, but the utility has not separately posted a 2026 fee notice. Sure Pay bank draft is advertised as free of charge from Great Oaks and the bank.
