Meter and infrastructure notes
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.
