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
- Residential customers may be billed monthly or bi-monthly depending on the account schedule. The FY2025/26 master fee schedule publishes separate single-family residential thresholds for monthly 0-5 CCF and 6+ CCF, and bi-monthly 0-10 CCF and 11+ CCF accounts.
- Rate structure
- Increasing block/tiered volumetric rates measured in CCF, where 1 CCF equals 748 gallons. For single-family/mobile-home customers, the FY2025/26 schedule lists monthly Tier 1 at 0-5 CCF and Tier 2 at 6+ CCF, or bi-monthly Tier 1 at 0-10 CCF and Tier 2 at 11+ CCF. Approved leak-adjustment usage is separately priced at $5.11 per CCF and limited to one adjustment for one billing cycle per year.
- Residential cost reference
- The FY2025/26 schedule lists residential water volume rates of $5.61 per CCF for the first block and $6.54 per CCF above the threshold, before fixed charges, wastewater, and other utility components. A 5,000-7,000 gallon monthly household uses about 6.7-9.4 CCF, so the volumetric water portion is approximately $38-$60 before fixed charges and sewer; the exact combined bill depends on the account’s monthly/bi-monthly schedule and current FY2026/27 adopted rates.
- Wastewater and sewer calculation
- Sunnyvale publishes water and wastewater as separate municipal utility charges. The reviewed master fee schedule identifies wastewater rates but does not expose a winter-average calculation in the accessible extract; the account bill and current rate resolution control the wastewater component.
