Forms and Applications

Below is a comprehensive list of forms and applications for receiving a determination from ADWR's Office of Assured and Adequate Water Supply. If you are unsure which application to submit please view the Quick Reference Flowchart. If you have any questions or need additional guidance, please call the program at (602) 771-8599.

The Department’s goal is to assist applicants in submitting complete and correct applications. The Department encourages applicants to schedule a pre-application meeting prior to submitting any application. To schedule a pre-application meeting, please submit a completed pre-application form by email to: [email protected]

NOTE: The pre-application form was updated in July 2021 to allow the applicant to select the type of meeting they would prefer (Virtual (via Google Meets), In-person, or Hybrid (some virtual / some in-person)). To submit an application in person, or pay the initial application fee by credit card, please email [email protected] to schedule an appointment.

Demand Calculator

The applicant may use either the Subdivision/Development water demand calculator provided by the Department to estimate the subdivision's demand OR provide its own demand calculations along with a detailed explanation of the assumption(s) and justification(s) used to estimate the subdivision’s demand.

NOTE: The Department's demand calculator can be found below, under Assured Water Supply or Adequate Water Supply. Please reference the demand calculator and/or assumptions used, as an attachment to the submitted application.

About the Demand Calculator

Assured and Adequate Water Supply applicants must submit adequate documentation and justification for the anticipated water use of the planned development.

ADWR’s generic demand calculator is an optional tool that applicants may use to estimate water demands for proposed developments.

The calculator uses baseline demand data that are consistent with the current management plan for each AMA, reported water use data, as well as US Census data compiled by the Department’s Active Management Area (AMA) staff at a county level.

AMA staff periodically reevaluate water demands for new development within each AMA and update the values used in the demand calculator to reflect increasing reductions in water demand for new development over time.

Applicants are free to adjust values in the demand calculator to account for the specific circumstances or features of their project.

Examples of features that may reduce water demand beyond what is typical for newer development within the given AMA include: specific technologies such as US EPA WaterSense labeled fixtures, homeowners association or subdivision covenants, landscaping requirements and features, and/or integrated hardscapes or natural areas. Exterior water demands–landscaping, turfed areas, pools, water features, etc.—offer the greatest potential for reductions in a residential subdivision. In commercial, institutional, and industrial facilities, dry-cooled systems instead of traditional evaporative cooling towers are an example of technology available to reduce demand.

Please note that any adjustments made to the assumptions used in the demand calculator need to be documented, accompanied with justification, and reviewed and approved by Department staff.

Applicants are free to submit a demand calculator of their choosing.

The applicant may submit a custom accounting of water demand for a project, so long as it includes all the demands (residential and non-residential) associated with the development. This includes, but may not be limited to, housing types (single/family, multifamily), commercial/industrial demands (as part of a master planned community), external use on landscaping, adjustments for large lots (average lot size greater than 10,000 sq/ft), common areas, rights-of-way and special features such as golf courses, community swimming pools, and lakes, distribution losses, construction demands, etc.

The AMA management plans have additional information and requirements for conservation practices, turf, and low water use plants that can be used in developing demand calculations.
