Assured and Adequate Water Supply, Rule Modification Technical Corrections, Depth Exemption, Grey Water, and Importation Priority
 Currently the Department is working with stakeholder groups to modify the Assured and Adequate Water Supply rules. The Department is modifying the Assured Water Supply rules for the Santa Cruz AMA. For the latest information on this process click here. Aditionally, the Department is modifying the Water Adequacy Rules as required under SB 1575 passed by the legislature in 2007. SB 1575 allows local platting entities (counties, cities and towns) to require water adequacy determinations for new subdivisions for the latest information on this process click here.
The Arizona Department of Water Resources established an informal stakeholder group
to facilitate public input on proposed rule modification of the assured and adequate water supply rules.
In addition to technical correction of drafting errors, the proposed rules will cover three areas:
modification of the depth exemption rule in the adequacy program, rule on the inclusion of grey water for assured and adequate water supply applications,
and a rule clarifying the relative priority dates for areas involving importing groundwater into Active Management Areas (AMA’s).
A brief summary of the proposed changes is available here (Proposed Changes Summary). 
A full description of the changes and the draft rule language itself is available here (Rule Summary Draft).

Assured and Adequate Water Supply
Proposed Rulemaking
On April 3, 2007, the Governor's Regulatory Review Council ("GRRC") approved the Notice of Final Rulemaking for the Pinal AMA AWS rules and submitted them to the Secretary of State's office on the same day. The rules will become effective on October 1, 2007.
For more information on the changes that will take effect on October 1, 2007, please review the Notice of Final Rulemaking in the Arizona Administrative Register at 13 A.A.R. 1394 (April 20, 2007), which can also be found on the Secretary of State's website at
http://www.azsos.gov/public_services/Register/2007/16/final.pdf. 
To view an unofficial, unmarked version of the rule language that will take effect on October 1, 2007, click here.  Please note that if there are differences between the unofficial version and the version published by the Secretary of State, the official version published by the Secretary of State shall take precedence.

The Office of Assured and Adequate Water Supply manages
applications for both the Assured Water Supply program and the Adequate Water
Supply program. The Assured Water Supply Program covers subdivisions within
Active Management Areas (AMAs) while the Adequate Water Supply Program covers
developments outside of the AMAs. Four types of applications are processed in
each of these roughly parallel programs: Physical Availability Demonstration
(PAD), Designation of Assured (or Adequate) Water Supply, Analysis of Assured
(or Adequate) Water Supply, and either Certificate of Assured Water Supply or
Water Adequacy Report. For application forms,
click here. For a spreadsheet
that helps estimate total projected demand for the proposed subdivision—needed
on the application—click
here.
Both programs are driven by the
definition of a subdivision from the Arizona Department of Real Estate (ADRE)
as six or more parcels with at least one parcel having an area less than 36
acres. This includes residential or commercial subdivisions, stock
cooperatives, condominiums, and all lands subdivided as part of a common
promotional plan (including golf courses, parks, schools, and other amenities).
Short-term leases (12 months or less) and subdivisions where all parcels are
greater than 36 acres in size do not fall under this definition. If the
proposed development does not meet the definition of a subdivision, then neither
program applies.
The Assured Water Supply program was created as part
of the historic 1980 Groundwater Management Act, and operates within Arizona’s
five Active Management Areas. Every developer is required to demonstrate an
assured water supply that will be physically, legally, and continuously
available for the next 100 years before the developer can record plats or sell
parcels. The ADRE will not issue a public report, which allows the developer to
sell lots, without a demonstration of an assured water supply. The developer
can prove a 100 year supply by satisfying the requirements to obtain a
Certificate of Assured Water Supply or by a written commitment of service from a
provider with a Designation of Assured Water Supply.
Applications for Certificates of Assured Water Supply
comprise the majority of applications processed within the Assured Water Supply
program. Other types, such as PADs or Analyses (but not Designations) usually
lead to the issuance of one or more Certificates for a subdivision or master
planned community, but do not demonstrate an assured water supply in and of
themselves. In order to obtain a Certificate of Assured Water Supply, five
criteria must be met:
1. The water supply must be physically, legally, and continuously
available for the next 100 years.
2. The water must meet water quality standards or be of sufficient
quality.
3. The proposed water use must be consistent with the management goal
of the AMA.
4. The proposed water use must be consistent with the current
management plan of the AMA.
5. The developer must demonstrate the financial capability to
construct any necessary water storage, treatment, and delivery systems.
The Department reviews each application under a 210 day
time frame. Incomplete or incorrect applications or lack of supporting
documentation lengthen the actual review period. The time frame does not apply
while the Department is waiting for the applicant to respond to requests for
additional information. For a summary of the Assured Water Supply program, see

The Adequate Water Supply program, first created in
1973, operates outside of the Active Management Areas as a consumer protection
program. Developers are required to obtain a determination from the Department
concerning the quantity and quality of water available before the ADRE will
allow any lot sales. If the application for a Water Adequacy Report
successfully demonstrates that water of sufficient quality will be physically,
legally, and continuously available for the next 100 years, then the Department
will determine the water supply to be adequate. If the water supply is
determined to be inadequate, the developer may still sell lots, but the
inadequate determination must be disclosed to potential buyers in the public
report approved by ADRE and in all promotional materials.
If a provider with a
Designation of Adequate Water Supply will serve the proposed subdivision, then
the developer only has to provide a written commitment of service from the
designated provider.
For more general information on the Adequate Water Supply
program, see the brochure at the bottom of this page or

determination as either adequate or inadequate, scroll down to the heading
entitled “Determinations of Adequate Water Supply.”
Determinations of Adequate Water Supply
The following is a list of recently issued Designations of Adequate Water
Supply and Water Reports determining adequate or inadequate subdivision water
supply in areas located outside of active management areas in the state,
pursuant to A.R.S. § 45-108. The list is provided for public information
purposes only and is not public notice of pending applications before ADWR
pursuant to A.A.C. R-12-15-721 or A.R.S. § 45-578.
