Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Bi-monthly; Great Oaks states that residential customers receive six bills per year, with each example billing period approximately 54-66 days.
- Rate structure
- CPUC-regulated readiness-to-serve monthly meter charge plus increasing-block residential usage tiers billed in 100-cubic-foot units (1 CCF = 748 gallons), with separate uniform rates for non-residential customers. The July 1, 2026 schedule lists a 3/4-inch monthly readiness charge of $32.49 and residential usage rates of $2.9454 per CCF for 0-12 CCF, $5.0831 for more than 12 through 20 CCF, and $7.0177 above 20 CCF, plus applicable purchased-power, CAP, CPUC and San Jose tax charges.
- Residential cost reference
- Approximately $62 per month for a standard 3/4-inch residential meter using 6,000 gallons monthly, annualized from the July 1, 2026 bi-monthly structure: roughly 16 CCF per two-month bill, $64.98 readiness charge, tiered usage, the published $0.1469 purchased-power and $0.1917 CAP surcharges, then the 0.70% CPUC surcharge and 5% San Jose tax. Actual bills vary with meter size, service days, CAP enrollment and surcharges.
- Wastewater and sewer calculation
- Great Oaks is a potable-water company and the reviewed tariff/rate pages describe water charges only. No Great Oaks residential sewer/wastewater intake formula, winter average or sewer percentage is published for this record; sewer service may be billed by another provider in the service area.
- Meter reading
- Residential meters are read for the bi-monthly billing cycle, but the reviewed Great Oaks pages do not identify AMR/AMI radio technology or a transmission interval. The bill-calculation page states that consumption equals ending meter read less beginning meter read over an approximately 54-66-day cycle.
- New-account deposit
- A security deposit is mandated by Great Oaks' CPUC tariff and is payable upon discontinuance of service for nonpayment. The amount is held in trust and credited back when the account has remained current for an entire calendar year or when service closes, whichever occurs first. The reviewed pages do not expose a universal startup dollar amount or credit-check waiver.
