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
- Most residential and business customers are billed bi-monthly under the company’s common General Meter Service schedule, although tariff service charges are expressed per month and some account configurations can differ. SJW’s bill describes a billing-period date range and current/previous meter readings; customers should follow the due date printed on the individual statement.
- Rate structure
- Increasing conservation tiers plus a meter-size service charge under CPUC-approved Schedule 1 General Meter Service. For 2026 residential customers with a 5/8- or 3/4-inch meter, the CPUC rate materials show approximately $73.23 per month service charge and quantity rates of $4.3617/CCF for 0–6 CCF per month, $6.5100/CCF for over 6 through 12 CCF, and $12.4341/CCF above 12 CCF. A 5% San Jose utility-users tax applies to applicable City accounts, and the bill also includes CPUC-authorized surcharges such as CAP, Safe Drinking Water, reimbursement, M-WRAM, and time-limited Valley Water pass-through charges. Effective July 1, 2026, SJW states that a 3/4-inch customer using 10 CCF per month sees about $4.86 per month of additional wholesale/pass-through and smart-meter-related impact compared with the prior period.
- Residential cost reference
- Approximately $115–$145 per month for a typical 5/8- or 3/4-inch residential account using about 5,000–7,000 gallons (roughly 6.7–9.4 CCF) before CAP assistance, depending on the billing period, applicable taxes, surcharges, and the July 2026 pass-through. The 2026 tariff components are a roughly $73.23 monthly service charge plus first- and second-tier quantity charges; the company’s published July 2026 comparison says a 3/4-inch customer at 10 CCF receives an additional $4.86 monthly impact from the new pass-through period. SJW is a water retailer; sewer charges are generally billed by a separate municipal or local sanitary agency.
- Wastewater and sewer calculation
- San Jose Water Company’s PWS and customer bills cover retail drinking-water service, not a universal SJW wastewater charge. Sewer and wastewater billing is handled by the customer’s local city or sanitary district, so there is no single SJW winter-average, flat-percentage, or water-intake sewer formula to apply across the entire PWS service territory. Customers should identify the separate sewer agency on their municipal bill or property account; SJW quantity charges themselves are based on metered CCF water consumption.
- Meter reading
- SJW is installing smart meters across its service territory from 2024 through 2027. Once installed, customers can view daily usage, monitor consumption, set unusual-use or potential-leak alerts, and use SJWaterHUB tools to understand bills. Until the rollout reaches a property, the system remains mixed smart/legacy metering with field or remote reads; SJW’s high-bill process uses meter readings and may arrange a Field Service investigation. Residential accounts are generally billed bi-monthly, and the bill records current and previous readings for the billing period.
