HB 2103 Arizona House · 57th Legislature - Second Regular Session

water improvements program; water hauling

HB 2103 creates a program to provide financial assistance to low-income or fixed-income homeowners in Arizona for specific water-related improvements. The program would fund deepening existing drinking water wells, installing storage tanks for water hauling, or plumbing for water delivery systems at the homeowner's residence. A designated county entity (like a department or nonprofit) would manage the program, set eligibility criteria, and report annually to county and state officials. The bill prohibits using general county funds, requiring funding to come only from gifts, grants, or donations.

MODERATE

The bill was amended to add a new section establishing a groundwater transportation fee for moving water out of specific basins, while simultaneously creating an exception that allows counties to use a portion of these fees to fund water improvements for local residents. Previously, the bill only focused on the water improvements program; now it directly regulates the financial cost of transporting groundwater and provides a mechanism for counties to reinvest those fees into helping homeowners who receive that water.

Scope change

The bill's scope expanded from solely regulating the water improvements program to also establishing a new fee structure for transporting groundwater and defining how counties can allocate those funds.

FISCAL

Added a new statute (Section 45-556) that imposes an annual groundwater transportation fee on entities moving groundwater out of specific basins, with fees increasing based on the volume transported.

Created a new provision allowing counties to designate a specific amount or percentage of the collected transportation fees to be used exclusively for water improvements for residential property owners living within the water source basin.

ELIGIBILITY

Modified the water improvements program rules to clarify that general county funds cannot be used for grants, except for the specific portion of transportation fees designated by the county for local residents.

REQUIREMENT

Added detailed requirements for calculating the transportation fee based on acre-feet transported and established a system for credits against these fees based on property tax changes and land donations.
