Arizona Department of Water Resources

Arizona Department of Water Resources (ADWR) – Per the 1980 Groundwater Management Code, ADWR has various responsibilities to regulate groundwater and other water sources and how water providers use that water. The State of Arizona has five active management areas (AMAs), including the Tucson Active Management Area (TAMA), which is the focus of ADWR’s management plans and water regulations. The District interacts with ADWR for a variety of issues from well permitting to obtaining a permit for recharge projects.

Assured Water Supply Designation – In early 1996, the District’s Metro Main service area received an assured water supply designation that requires it to be using 100 percent renewable supply by 2025. Metro Hub does not have an assured water supply designation. In 2015, the District received an assured water supply designation for the Metro Southwest – Diablo Village service area. ADWR’s goal for the Tucson Active Management Area is to be at safe-yield by 2025. ADWR also oversees how assured water supply credits are acquired through various recharge efforts.

Safe-Yield – Safe-yield is to ensure that the amount of groundwater withdrawn equals the amount of water that is replenished through natural or man-made recharge in the TAMA.

Management Plan – Every ten years per statute, a management plan is developed by ADWR to oversee various regulations in order to move an active management plan closer to safe-yield. ADWR’s Fourth Management Plan was published in September 2016.

Conservation Regulations – ADWR regulates municipal water providers under the Total Gallons Per Capita per Day (GPCD) Program. A water provider is to meet a GPCD target as established under the current management plan. In 2006, ADWR initiated a stakeholder process to revisit the Total GPCD Program. The concept of a Best Management Practices (BMP) was developed in which the focus would be on the actual implementation of conservation programs rather than meeting a numerical target. ADWR was able to gain legislative approval in 2007 to make the changes. The new program is called the Modified Non-Per Capita Conservation Program. The District was actively involved in the stakeholder process.
