Earlier this year, the Pinal Stakeholder Group presented the results of its own modeling analysis to ADWR.
That research, performed for the Pinal Stakeholder Group by Matrix New World Engineering, constituted a polished and professional, good-faith attempt to bridge the water supply gaps identified by ADWR in 2021. ADWR is grateful to the Pinal Stakeholder Group for its work.
Nevertheless, ADWR has requested that the Stakeholder Group review a number of elements of its modeling, including technical corrections that, until addressed, will not allow ADWR to determine whether any unmet demand remains.
Among the model elements ADWR has asked to be reviewed are matters involving depth-to-water exceedances; underestimating the demand of the City of Eloy; the movement of water among service areas, often miles away from each other; as well as other matters. ADWR has asked the Pinal Stakeholder Group to review several other key findings of the Stakeholder Model, including its conclusions about the manner in which irrigated agricultural land is urbanized.
Depth-to-water exceedances and continuing concerns about unmet demand in the Pinal AMA could affect future assured water supply applications. As a result, ADWR cannot move forward in processing applications based on the current Pinal Stakeholder Model submission.
Although the Pinal Stakeholder Model submission is a good-faith effort, it does not yet meet assured water supply requirements.
