Riverside 2026 Commercial Water Rates: Seasonal CCF and Meter Charges
Riverside’s July 2026 WA-6 rates separate seasonal commercial water volume, meter-size customer charges, territory, and a quarterly energy adjustment.
Direct answer
Riverside’s July 1, 2026 WA-6 rates charge inside-city commercial and industrial accounts $2.15 per CCF in winter and $2.33 in summer, plus a meter-size customer charge. Outside-city accounts pay 1.5 times those base charges. Usage reduction can lower the quantity line, but not the fixed meter charge; verify any quarterly energy adjustment separately.

Official source facts
The current WA-6 schedule controls the July 2026 rate step
Riverside Public Utilities’ current WA-6 schedule was adopted as part of a multi-year plan and later amended. Its document header retains the original October 1, 2023 effective date, while the rate table provides separate future columns. The values in this article come from the column effective July 1, 2026.
The current schedule linked from RPU’s live Rules & Rates index supersedes an older 2023-only URL. Use the live index and current amended PDF when reconstructing an account rather than carrying an older schedule forward.
Class, season, and meter
Commercial volume and the customer charge follow separate tables
Inside the city, WA-6 commercial and industrial quantity rates are $2.15 per CCF in winter and $2.33 per CCF in summer. Summer applies to service rendered in June, July, August, September, and October; all other months use the winter rate. The schedule applies to multifamily accommodations with five or more dwelling units as well as commercial and industrial service, subject to its stated service and metering rules.
A meter-size customer charge is added to quantity cost. The July 2026 table runs from $33.36 per month for a 5/8- or 3/4-inch meter to $3,864.36 for a 12-inch meter. The $158.72 two-inch charge used below is only a declared reference; lower monthly use does not change that fixed meter-size line.
Territory and adjustments
Outside-city service and energy cost require separate checks
WA-6 says surcharge-area service outside the city is billed at 1.50 times both the inside-city quantity rates and customer charge. Confirm the service territory on the account rather than inferring it from a postal address.
The current schedule also says the Water General Fund Transfer is a component of customer bills and that quantity rates are subject to a quarterly energy-cost adjustment for pumping. The document describes the mechanism but does not provide a current account-ready adjustment factor, so the model below does not invent or apply one.
Adopted plan context
The official 6.3% figure is a reference bill, not a universal multiplier
RPU’s adopted-plan page shows a 6.3% July 1, 2026 change for its commercial and industrial reference bill at 37 CCF. That is a defined planning example, not a safe percentage to apply to every commercial account. Actual exposure changes with season, volume, meter size, territory, adjustments, and other services.
RPU connects the multi-year plan to inflation, reserves and bond financing, system maintenance and capital work, aquifer viability, and regulatory compliance. Those explain the system need; they do not replace account-level bill reconstruction.
Dated efficiency programs
Rebates require a separate live eligibility check
RPU’s business rebate page directs commercial customers to water-efficiency programs. It currently describes turf replacement at $2 per square foot for applications beginning March 1, 2026, up to 50,000 square feet, and a Water Savings Incentive Program for qualifying nonresidential projects.
Program eligibility, funding, availability, baseline rules, installation approval, and payment should be confirmed with RPU and the linked SoCal WaterSmart program before acting. A rebate is not automatic and is not part of the rate model below.
Commercial implication
Establish the account basis before estimating usage exposure
Hotels, industrial facilities, multifamily properties, restaurants, laundries, healthcare sites, campuses, and other users should first verify WA-6 classification, inside- or outside-city territory, billing season, meter size, and the quarter’s energy adjustment. Fire, irrigation, landscape, recycled-water, sewer, tax, and other account lines require their own controlling schedules or records.
Only after those checks should a team model the quantity line. This prevents a useful water-efficiency project from being evaluated against a fixed meter charge or another service it cannot change.
Smart Valve analysis — not an RPU bill quote
An inside-city 100-to-80 CCF summer example
Assume one inside-city WA-6 account in a June–October service month, using 100 CCF and then 80 CCF, with a declared two-inch meter. Include only base quantity and the listed customer charge. Exclude the quarterly energy adjustment, sewer, fire, irrigation, landscape/recycled schedules, taxes, rebates, and every account-specific line.
Scroll the table horizontally to compare all columns.
| Included line | 100 CCF | 80 CCF | Change |
|---|---|---|---|
| Summer quantity | $233.00 | $186.40 | Decrease $46.60 |
| 2-inch customer charge | $158.72 | $158.72 | Unchanged |
| Included partial total | $391.72 | $345.12 | Decrease $46.60 |
The base quantity calculation is 100 × $2.33 = $233.00 and 80 × $2.33 = $186.40. The $46.60 difference applies only to inside-city summer quantity. The declared $158.72 two-inch customer charge remains unchanged.
20% usage check
$46.60
Qualified 20% summer quantity exposure
In the declared inside-city example, summer quantity falls from 100 to 80 CCF and the included base volume line falls by $46.60. The two-inch customer charge remains $158.72.
Boundary: This is reproducible analysis, not an RPU quote, whole-bill forecast, or savings guarantee. The energy adjustment, General Fund Transfer treatment, outside-city factor, sewer, other service schedules, taxes, rebates, and account-specific charges remain outside the figure.
Decision checklist
What to check first on the bill
- 1Confirm the account belongs on WA-6; do not apply it to an excluded irrigation, residential, fire, landscape, or recycled-water service.
- 2Match the service month to the June–October summer rate or the November–May winter rate.
- 3Verify inside- or outside-city territory and apply the 1.50 factor only when the utility classifies the service in the surcharge area.
- 4Confirm meter size and separate the monthly customer charge from the usage-linked quantity line.
- 5Check the current quarterly energy adjustment and every separate service, tax, fee, or rebate directly with RPU before completing a budget.
Scope boundary
Where Smart Valve realistically fits
Smart Valve can be screened against controllable metered volume and the WA-6 quantity line attached to that volume. It does not change RPU’s season, rate class, territory, meter-size customer charge, General Fund Transfer policy, quarterly energy adjustment, other utility schedules, taxes, or rebate decisions.
A credible assessment starts with at least 12 months of bills, service territory, meter size, billing periods, current adjustments, and the property’s operating profile. The calculator is directional and does not reproduce Riverside’s seasonal, territory, fixed-charge, or energy-adjustment mechanics.

Frequently asked questions
Which Riverside accounts use the WA-6 schedule?
WA-6 applies to eligible commercial and industrial metered service and to multifamily accommodations with five or more dwelling units. The schedule excludes services that qualify for other listed schedules, so the utility classification should be confirmed.
When does Riverside use the summer commercial water rate?
The $2.33-per-CCF summer rate applies to service rendered in June through October. November through May uses the $2.15 winter rate for the July 2026 WA-6 column.
How does Riverside price WA-6 service outside the city?
WA-6 says surcharge-area service outside the city is billed at 1.50 times both the inside-city quantity rate and customer charge. The account’s territory should be verified with RPU.
Does lower usage reduce Riverside’s fixed meter charge?
No. Lower metered use can reduce the applicable quantity line, but the customer charge follows meter size. Energy adjustments, other services, taxes, and account-specific lines can also prevent an equal percentage change in the complete bill.
