HB 2758 Arizona House · 57th Legislature - Second Regular Session

McMullen Valley; eligible entities; groundwater

HB 2758 allows eligible entities (state, local governments, or regulated public utilities) to withdraw and transport groundwater from historically irrigated land in Arizona's McMullen Valley groundwater basin under strict conditions. It permits up to 6 acre-feet of groundwater per acre per year (or 30 acre-feet over a decade), requires hydrological studies and water-measuring devices, and mandates monthly reports on withdrawal and transport volumes. The groundwater can only be sent to specific locations, including active management areas or La Paz County (with a 10% annual volume cap), and must not cause excessive groundwater decline. Entities must submit annual reports to the state department detailing all transported water.

Introduced Version → House Engrossed Version (02/19/2026) · 5 edits · Feb 19, 2026

MODERATE

The bill was significantly rewritten to add a new land disclosure form for real estate transactions and a county water improvement grant program, while updating groundwater transport rules to align with the new disclosure requirements. The original text focused solely on groundwater transport in the McMullen Valley, but the new version expands the scope to include consumer protections for homebuyers regarding water access and funding for low-income residents to upgrade their water wells.

Scope change

The bill's scope expanded from a single groundwater transport provision to include a new land disclosure affidavit for residential real estate sales and a new county program to fund water well improvements for low-income homeowners.

REQUIREMENT

Added a new 25-item disclosure affidavit that sellers must provide to buyers, including specific questions about water hauling, well registration, and groundwater transport basins.

FISCAL

Created a new county program allowing grants for low-income residents to deepen wells, install storage tanks, or fix plumbing for water delivery systems.

DEFINITION

Updated the groundwater transport statute to reference the new disclosure form and clarify how local water use counts against withdrawal limits.

ENFORCEMENT

Modified fee collection rules to allow counties to designate a portion of groundwater transport fees specifically for the new water improvement grant program.

TECHNICAL

Removed the original introductory text and repealed the previous version of the groundwater transport section to replace it with the updated text.
