Leak relief and household assistance

A high water bill may have a path to review

Hidden plumbing failures can produce an alarming bill before the problem is visible. This guide separates what Great Oaks Water Company publicly describes from the practical steps every customer can take while requesting help.

Provider-specific review

What the public record says about a leak adjustment

Great Oaks’ public material explains detection and prevention rather than publishing a current bill-credit formula. A customer should first read the meter, stop every water use in the building for two hours—including toilets, dishwasher, and clothes washer—and read it again; movement indicates a leak and the customer should promptly contact a plumber. The customer should repair the leak, retain the plumber’s invoice, parts receipts, photographs, and before-and-after meter readings, then call (408) 227-9540 to ask whether the account qualifies for discretionary relief or a bill review. The accessible 2026 Great Oaks pages do not state a percentage reduction, look-back average, maximum credit, repair deadline, or guaranteed adjustment, so no exact leak-credit amount can be represented as an official current rule.

Stop the loss

Shut off the failing fixture or supply and arrange a qualified repair.

Keep proof

Save dated invoices, parts receipts, photographs, and meter readings.

Request review

Submit the request promptly and keep paying any undisputed amount.

Utility assistance

Customer assistance and eligibility

Great Oaks’ CPUC Rule 22 Customer Assistance Program (CAP) is for individually metered residential customers who qualify for PG&E California Alternate Rates for Energy (CARE) and are billed in the same manner as PG&E. Master-metered customers are excluded. Applicants complete the company CAP application and provide a current PG&E bill showing CARE eligibility; certification lasts 12 months and must be renewed annually. Great Oaks notifies customers about the program twice each year through a bimonthly bill insert. Qualified customers receive a 50% reduction in the authorized bimonthly water-service charge; non-CAP customers fund the program through a quantity surcharge, which the July 2026 bill calculator shows as $0.1917/CCF beginning July 1, 2026. The application may be emailed to customerservice@greatoakswater.com.

State and federal connections

Where to ask for broader aid

Great Oaks’ home page directs customers with large past-due balances to California’s Low Income Household Water Assistance Program and explicitly says the utility is not permitted to enroll customers itself; applicants must use the state link. California CSD’s current page states that LIHWAP applications are closed and that the federal program sunset March 31, 2024, with only a supplemental benefit for households that previously received LIHWAP. Great Oaks’ locally administered support is the CPUC CAP described above, plus bill review and payment arrangements through Customer Service. Customers should check https://www.csd.ca.gov/waterbill for any successor aid and coordinate any agency payment with Great Oaks so it is credited to the correct account.

Leak and assistance notes

Build the file before asking Great Oaks Water Company for relief

A high bill can have several causes, including a hidden plumbing failure, irrigation use, a meter issue, a change in occupancy, or a rate adjustment. The provider’s leak policy determines whether any credit is available; an unusually high bill does not automatically qualify.

Keep a dated record of the reading, the suspected source, the repair, the contractor or parts receipt, and the return to normal use. Ask whether the utility requires a specific form, a licensed repair, a meter test, photos, or a request within a fixed number of days.

For income-related difficulty, ask about local assistance, payment arrangements, state programs, and community referrals separately from a leak adjustment. These programs often use different applications, documents, funding limits, and deadlines.
