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
- Monthly, with meters read and billed by geographic cycles. Fontana says it attempts to read all meters within 27–33 days, and its billing instructions describe monthly service charges and consumption units.
- Rate structure
- CPUC-regulated general metered conservation rates with three increasing consumption tiers and a fixed meter service charge. The publicly indexed 2026 tariff material for the 5/8-by-3/4-inch residential meter shows $21.68 per month, $4.5048 per CCF for the first 12 CCF, $5.1580 for the next 12 CCF, and $6.6610 for consumption above 24 CCF, subject to CPUC-approved surcharges and surcredits. Fontana’s regulatory page also links a July 2026 General Rate Case advice letter effective July 20, 2026; the PDF was access-blocked during native review, so customers should confirm the effective tariff with the company or CPUC before treating the indexed figures as the final post-July rate.
- Residential cost reference
- The company’s official 2026 General Rate Case fact sheet estimates $90.50 per month for a typical 5/8-inch conservation-rate customer using 12 CCF (about 8,977 gallons), up from $79.73, and $74.15 for a qualifying CAP customer. A 5,000–7,000-gallon customer uses about 6.7–9.4 CCF and will generally fall below the 12-CCF example, but the exact bill depends on the effective CPUC tariff, meter charge, CAP status, and applicable 2026 surcharges or surcredits. Fontana Water Company provides potable water only; it does not bill sewer or wastewater service.
- Wastewater and sewer calculation
- Fontana Water Company provides potable water service only and explicitly states that it does not provide sewer or power services. Therefore, the company does not calculate or collect a wastewater charge relative to clean-water intake, does not use a winter-average sewer formula, and does not apply a flat sewer percentage. Any sewer bill for a customer in Fontana, Rialto, or Rancho Cucamonga comes from the separate municipal or regional wastewater provider serving that parcel.
- Meter reading
- Fontana reads and bills all meters in geographic cycles every 27–33 days. The company supports both classic mechanical meters and AMR meters: classic meters display cubic-foot totals and ignore the final two black-background digits for billing, while AMR meters display total cubic feet and ignore the final five digits. AMR displays can show a faucet icon for intermittent or continuous leakage during the prior 24 hours. The reviewed materials do not establish full AMI hourly transmission; the defensible description is scheduled monthly-cycle reading with classic and automated meter-reading equipment.
- New-account deposit
- Fontana requires a customer guarantee deposit under its CPUC rules when credit has not been established; the amount is account-specific rather than a single published residential dollar amount. The company’s guarantee receipt states that the deposit may be applied to unpaid balances, earns interest at 7% per year, and is refundable after the deposit has been held for 12 consecutive months when service remains continuous and bills are paid according to the rules, or upon discontinuance after deducting unpaid water bills. Temporary construction meters require a $1,500 deposit plus an estimated amount based on expected project usage.
- Activation or transfer fee
- The company says residential or business service applications should be submitted at least 24 hours before the requested start date on a regular business day, with proof of ownership or rental agreement potentially required. The reviewed customer pages do not publish a universal 2026 residential activation or transfer fee; customers should request the application from CustomerService@fontanawater.com and confirm any credit, deposit, field, or transfer charges at (909) 822-2201. Stop-service requests should be made at least two business days in advance.
