Phoenix AMA Management Goal

Downtown Phx (PhxAMA)





The Phoenix AMA is tasked by Statute to achieve safe-yield by the year 2025 through the increased use of renewable water supplies and decreased groundwater withdrawals in conjunction with efficient water use. 


PhxAMA Third Management Plan




One of the Department’s responsibilities under the 1980 Groundwater Code is to develop a management plan for each active management area for each of the five management periods spanning the years between 1980 and 2025.  The Code requires that each management plan include a continuing mandatory conservation program for all persons withdrawing, distributing, or receiving groundwater designed to achieve reductions in withdrawals of groundwater.


The first order of modifications to the Third Management Plan, adopted in May 2003, resulted in a number of changes to the conservation programs for agricultural, municipal, and industrial water users and to the Water Management Assistance Program.


The second order of modifications, adopted in May 2008, resulted in changes to the conservation programs for municipal water users.  Click here for the May 2008 Third Management Plan modifications. It includes a new regulatory program -- the Modified Non-Per Capita Conservation Program (MNPCCP).


The current conservation requirements for all users of groundwater within the Phoenix AMA are described in the Third Management Plan and its modifications.
