HB 2589: assured water supply; analysis; availability
Sponsor: Representative Dunn, LD 25
House Engrossed
Overview
Establishes criteria for the Arizona Department of Water Resources (ADWR) Director to
accept an analysis of assured water supply (analysis) as a valid demonstration of physical
availability of groundwater to meet the estimated demand of a proposed development.
History
A person proposing to develop land that will not be served by a designated provider may
apply for an analysis before applying for a certificate of assured water supply (Certificate).
An applicant for an analysis must be the owner of the land or have the written consent from
the owner.
The ADWR Director must issue an analysis if an applicant demonstrates:
1) sufficient supplies of water are physically available to meet all or part of the
estimated water demand of the development for 100 years;
2) sufficient supplies of water are continuously and legally available to meet the
estimated water demand of the development for 100 years;
3) the proposed sources of water are of adequate quality;
4) any proposed groundwater use is consistent with the management plan in effect at
the time of the application; or
5) any proposed groundwater use is consistent with the management goal (A.A.C. R12-
15-703).
Provisions
1. Requires the ADWR Director to accept, for the purpose of issuing a Certificate, an
analysis as a valid demonstration of physical availability for the volume of groundwater
after reducing the volume of groundwater stated in the analysis by the amount of
groundwater represented by all Certificates issued in reliance on the analysis, if the
analysis:
a) was issued by the ADWR Director by May 31, 2023;
b) has not expired; and
c) includes a determination of physical availability of groundwater. (Sec. 1)
2. Instructs the ADWR Director to issue new Certificates based on the current water
demand assumption in use when the application for a Certificate was submitted. (Sec. 1)
3. Stipulates that when a certificate is issued, the analysis must be reduced by the volume
of groundwater using the same water demand assumption the ADWR Director used when
the analysis was originally issued. (Sec. 1)

4. States that the difference in volume between the current water demand assumption and
the water demand assumption used for the initial analysis must remain physically
available for further subdivision development in service areas of the designated provider
serving the analysis land. (Sec. 1)
5. Defines analysis to mean a determination by the ADWR Director that one or more criteria
required for a Certificate have been demonstrated for a development. (Sec. 1)
