Billing frequency

Provider briefing
How this utility’s billing works
Cucamonga Valley Water District operates as a public water authority serving Rancho Cucamonga, Upland, Fontana, Ontario, and adjacent San Bernardino County service areas served by the District. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Metered four-tier increasing-block rates with monthly meter-service charges proportional to meter hydraulic capacity. Effective January 1, 2026, the published rates are $1.88/HCF in Tier 1, $2.33/HCF in Tier 2, $3.98/HCF in Tier 3, and $4.22/HCF in Tier 4. A typical 3/4-inch meter has monthly tier thresholds of 6, 18, and 36 HCF; a 1-inch meter has thresholds of 10, 30, and 60 HCF. The 2026 monthly meter charge is $28.26 for 3/4 inch and $44.78 for 1 inch. CVWD may also pass through independently approved Metropolitan Water District and Inland Empire Utilities Agency charges.. Bills are generated monthly. cvwd changed to monthly billing to provide more frequent consumption information and earlier leak detection. the level-billing plan spreads the annual water-and-sewer cost into eleven equal payments with an annual settlement statement, but it does not change the underlying monthly billing cycle or eliminate responsibility for actual use., and a typical residential cost reference is For a typical 3/4-inch residential meter using 5,000–7,000 gallons per month, consumption is approximately 6.7–9.4 HCF. Under the 2026 allocation, the first 6 HCF are charged at $1.88/HCF and the balance is charged at $2.33/HCF, producing approximately $13–$21 in monthly commodity charges plus the $28.26 meter charge, or roughly $41–$49 per month for potable water before sewer, pass-through agency charges, recycled-water charges, taxes, or conservation surcharges. A 1-inch meter has a $44.78 base charge and remains in Tier 1 for this usage range.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
CVWD bills sewer/wastewater separately through the monthly utility statement where the property receives District sewer service. The level-billing plan combines annual water and sewer costs for its equal-payment calculation, but actual charges are reconciled annually. The reviewed 2026 customer pages do not state a single residential winter-average formula; sewer rates and any equivalent-dwelling-unit/service classification are controlled by CVWD’s wastewater schedule and applicable pass-through charges rather than a simple fixed percentage of potable intake.
Meter and infrastructure notes
CVWD uses metered monthly billing and a separate Water Monitor Portal for usage information and leak awareness. The District’s four-tier allocations are based on the exact hydraulic capacity of the customer’s meter, and its customer-service/usage history tools support high-consumption inquiries. The reviewed 2026 public pages do not identify the AMI/AMR manufacturer, universal transmission interval, or exact route-read calendar; the defensible description is monthly municipal metering with online usage monitoring and separate payment and monitoring logins.
Emergency water support
Report a leak or water emergency
855-654-2893, the District’s published customer-service number for billing, account, and water-service assistance. CVWD’s public pages do not expose a separate 24/7 water emergency hotline; use the official number and follow its after-hours instructions for a main break, street leak, or water-quality emergency. The District’s Leak Detection page provides customer steps for suspected private leaks.

Cucamonga Valley Water District is listed here as a public water authority. The profile separates account actions—such as paying a bill or requesting service—from explanatory material about rates, meters, wastewater, leaks, and delinquency.
Because utility rules can vary by account class, meter size, service address, billing date, and local ordinance, treat the published bill and current provider website as the final authority. Use this profile to locate the correct channel and prepare better questions for customer service.
If your issue is urgent, start with the provider’s emergency number or official payment route rather than waiting for an email response. Keep a written record of calls, confirmation numbers, notice dates, and documents you submit.
