HB 2545 requires developers to obtain a "certificate of assured water supply" from the Arizona director before selling or leasing subdivided lands in active water management areas, or secure a written water service commitment from a designated city, town, or private water company. It establishes a process where the director designates cities, towns, and water companies with verified water supplies, and mandates that subdivisions must comply with these requirements before plat approval or real estate registration. This directly affects developers of new housing subdivisions, local governments approving land plats, and private water providers serving those areas. The bill also allows for reduced water demand requirements if gray water reuse systems are installed, as defined by state environmental rules.
