Payment channels

Pay Great Oaks Water Company

Use the provider’s verified online, telephone, mail, or counter instructions. Check the final confirmation screen for the amount, processing date, and any transaction fee before submitting.

Primary online route

Use the official payment portal

The direct portal is the fastest route when it is available. The provider identifies its payment gateway as 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.. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

A dedicated this detail was not publicly posted. . Great Oaks publishes (408) 227-9540 for Customer Service and the official Heartland web link, but the current customer-facing pages do not publish a dedicated automated IVR payment number. The older CPUC tariff authorizes web/IVR card, debit, and ACH/e-check payments, so customers should obtain the current IVR number from Customer Service rather than rely on an unverified third-party number.

Have your account number and payment instrument ready. Follow the provider’s recorded prompts and retain the confirmation number.

Alternative channels

Mail, text, and in-person payment instructions

Pay by text

A dedicated this detail was not publicly posted. . Great Oaks does not publish a keyword-based text-to-pay enrollment program, SMS short code, or opt-in sequence on its current website. The customer can use the Heartland web portal, free Sure Pay bank draft, or contact Customer Service at (408) 227-9540 for any account-specific electronic-payment notification options.

Mail-in 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.

Counters, drop boxes, and office hours

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.

Accepted digital instruments

What you can use online

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.

2026 transaction pricing

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.

Fees can vary by payment type, channel, account class, and processor terms. The checkout screen is the final fee disclosure.

Payment guidance

Choose the payment channel that fits your deadline

The safest payment path is the one published by Great Oaks Water Company and matched to the account information on your bill. Online portals are convenient, but telephone, mail, counter, and drop-box options may follow different posting schedules and may use different fees.

For a routine payment, save the final confirmation page or IVR number and check when the transaction will post. For a same-day shut-off notice, do not assume that submitting a card payment automatically stops a field order; ask the provider what amount and confirmation are required.

Never send your account number, password, card details, or bank information to Water Ledger. Those details belong only on the provider’s verified payment channel or at an authorized counter.
