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. 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.
- Rate structure
- 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.
- Residential cost reference
- 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.
- 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 reading
- 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.
- New-account deposit
- CVWD’s published business service application states a $15 turn-on fee per account and at least a $175 deposit per account; domestic, fire-line, and landscape services may be separate accounts and the District may set account-specific requirements. Residential start-service pages require contact with Customer Service for the current advance payment and documentation. The reviewed current 2026 pages do not state a credit-check waiver or automatic refund period; confirm the exact deposit and any release rules at 855-654-2893.
- Activation or transfer fee
- A published CVWD business application states a $15 turn-on fee per account and says service requests are completed within 48 business hours after required information and payment. Residential customers must contact the District at 909-944-6000 or 855-654-2893 to open or close an account; the current public residential page does not state a separate transfer amount. Construction meters and fire/landscape accounts have distinct deposits, installation, and service charges.
