Assured water supply; agricultural water
SB 1260 would amend Arizona’s groundwater management law to expand the circumstances under which a city or town can receive an “assured water supply” designation in a waterlogged area within the Phoenix Active Management Area. Under current law, that designation is available only if the municipal area is within an irrigation and water conservation district or on lands served by an agricultural water company, and if the city or town has a 100-year contract for water, can show long-term water availability, and can finance the needed infrastructure. The bill keeps those core requirements but revises the statutory language governing the water source and delivery arrangement, clarifying that the water may come through an agricultural water company and that the water is to be treated and delivered for municipal use on irrigation and conservation district lands.
The bill also preserves the Department of Water Resources director’s authority to review and, if necessary, reverse an assured water supply determination within an exemption area established under section 45-411.01. In practical terms, SB 1260 would affect municipal development planning, water providers, irrigation and water conservation districts, and agricultural water companies by shaping when land in the Phoenix AMA can be treated as having a legally sufficient long-term water supply for development purposes.
The available legislative history suggests the bill has not advanced far and has faced a neutral-to-cautious reception so far. On February 5, 2025, the Senate Natural Resources Committee action was recorded as “HELD,” with no recorded yeas or nays, indicating the measure was set aside rather than voted through at that stage. No committee transcript was provided, so there is no direct record of floor or committee debate in the materials supplied.
Because the bill was held and there is no transcript, there is no documented public split in the provided record. The likely area of concern is the balance between facilitating municipal access to agricultural water supplies and maintaining Arizona’s groundwater management and assured water supply standards. Any contention would likely center on whether the bill makes it easier for cities to secure development-related water assurances, and whether that could affect existing agricultural water rights, conservation district operations, or the Department’s oversight role.
SB 1260 would amend A.R.S. § 45-576.10, a groundwater management provision governing assured water supply designations in certain exempt areas of the Phoenix Active Management Area. The bill would affect how the Department of Water Resources evaluates municipal applications tied to irrigation and water conservation districts or agricultural water companies, while leaving in place the 100-year contract, long-term water availability, and financing requirements. It would primarily impact cities and towns seeking development approvals, along with water districts, agricultural water companies, and state regulators responsible for assured water supply determinations.
The bill appears to have had limited momentum and a cautious reception in the Senate Natural Resources Committee, where it was held on February 5, 2025 without a recorded vote. With no committee transcript available, the overall sentiment can only be inferred from the procedural outcome: the measure was not advanced at that stage, suggesting either unresolved policy concerns or a lack of consensus. The bill’s subject matter is technical and likely appeals to stakeholders interested in water supply flexibility, but it also touches on sensitive groundwater management issues that often draw scrutiny.
The main points of contention likely involve whether the bill broadens municipal access to assured water supply designations in a way that could weaken existing safeguards, and whether the revised language appropriately protects agricultural and conservation district water uses. Potentially affected stakeholders include cities and towns seeking growth capacity, agricultural water companies, irrigation and water conservation districts, and the Department of Water Resources. Concerns may also focus on the adequacy of 100-year water contracts, the reliability of surface water or effluent supplies, and the director’s authority to review or overturn assured water supply findings.
