designation; assured water supply; offset

HB 2297 allows water providers in Arizona to count groundwater and stored water recovered outside their service area when applying for an "assured water supply" designation. It establishes a specific calculation method: adding 2023 water recovery data, multiplying by 100, then applying a 5% adjustment to new alternative water supplies. The bill requires financial proof for infrastructure construction and limits such designations to 15 years, with restrictions on adding new external water sources later. This directly affects municipal water providers and private companies seeking water supply approvals in Arizona's active management areas.
