Provider-specific findings
Relief research for this provider
The notes below may document a route, rule, or explicit public-information limit. General preparation steps are not represented as utility policy.
- Emergency reporting route
- Great Oaks’ after-hours emergency telephone number is (408) 879-8246. Customer Service during office hours is (408) 227-9540, with the office open Monday through Friday, 8:00 a.m.–5:00 p.m. The emergency page instructs customers not to remove a Great Oaks meter lock and to call the company when a locked meter prevents service; a broken lock can incur a $25 restoration charge.
- Leak-adjustment policy
- 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.
- Utility assistance program
- 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 aid connection
- 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.
