Rialto Utility Authority / Rialto Water Services, operated by Veolia North America
Central Rialto and the Rialto Utility Authority water-service area
Population reference
54,453 residents served by active CWS CA3610038 according to California Drinking Water Watch, with approximately 10,966 residential and 1,030 commercial metered connections. The City warns that other Rialto parcels are served by West Valley Water District or Fontana Water Company, so the figure applies to the City of Rialto system rather than every city resident.

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. Rialto Water Services states that ready-to-serve and base charges are billed monthly, and the billing regulations describe a monthly billing date and monthly consumption charges.
- Rate structure
- Increasing block volume tiers with a fixed monthly minimum charge. Effective March 1, 2026, a 3/4-inch-or-smaller meter has a $37.30 monthly minimum, and ordinary single-family, small multifamily, government, and commercial accounts pay $2.11 per CCF for 0–9 units, $2.37 per CCF for 10–30 units, and $3.45 per CCF for 31-plus units. Larger meters have higher fixed charges; large multifamily/mobile-home accounts and landscape accounts have separate classifications. One CCF is 100 cubic feet, or 748 gallons. The City suspended its residential Utility Users Tax for calendar year 2026.
- Residential cost reference
- Approximately $120–$130 per month for a typical 5,000–7,000-gallon single-family customer with a 3/4-inch-or-smaller meter, before any unusual charges. The March 1, 2026 estimate combines the $37.30 minimum water charge, approximately $14–$20 in first-tier water volume charges at 6.7–9.4 CCF, and the $69.16 monthly residential sewer charge. The temporary 2026 residential UUT suspension reduces the total compared with a normal 8% UUT year; actual costs vary by meter, consumption class, and provider boundary.
- Wastewater and sewer calculation
- For Rialto Water Services residential single-family and multifamily accounts, the March 1, 2026 sewer/wastewater charge is a fixed $69.16 per residential unit per month, rather than a winter-average percentage of clean-water intake. Commercial wastewater customers are assigned a group based on discharge characteristics and billed per CCF at published Group II, III, IV, or VI rates; schools are billed per average daily attendance. Extraterritorial sewer accounts are charged 1.3 times the applicable sewage charge. The water side remains separately metered and tiered.
- Meter reading
- Rialto Utility Authority is deploying AMI water meters to all customers through a grant-funded program supported by California DWR and the U.S. Bureau of Reclamation. The 2026 pre-installation audit documents meter size, serial numbers, and box dimensions; customers receive a postcard before replacement and a door tag after installation. The program is intended to improve read accuracy, give customers better usage information, and accelerate leak detection. The reviewed pages do not state the final transmission interval or portal vendor; during the transition, customers should use the current bill and Rialto Water Services account history for monthly billing verification.
- New-account deposit
- Residential water deposits equal two times the property’s average monthly water consumption for the preceding 12 consecutive months, with the exact amount influenced by the water-meter size and the prior-year average bill. Residential sewer deposits are $103. Deposits are credited back after two years of on-time payments and never appearing on the turn-off list. The City’s service page says customers should call (909) 820-2546 for the address-specific deposit amount before activating service.
- Activation or transfer fee
- The reviewed Rialto Water Services pages do not publish a universal 2026 residential turn-on or account-transfer fee separate from the required deposit. Customers establish or stop service through the Veolia-operated office at 437 N. Riverside Avenue or by calling (909) 820-2546; the deposit is based on meter size and historical average consumption. Confirm any address-specific activation, transfer, field, or returned-payment charge before the service date.
