The Arizona Water Banking Authority
The Arizona Water Banking Authority (AWBA; Water Bank) was established in 1996 to store the unused portion of Arizona’s annual Colorado River entitlement in Central and Southern Arizona. The AWBA stores water in underground aquifers to earn long-term storage credits (LTSCs). These credits can be recovered (pumped) during a shortage to provide back-up water supplies (known as "firming") for Arizona water users.
Through 2023, the AWBA has accrued 4,380,000 acre-feet of LTSCs: 3,770,000 acre-feet for Arizona uses and 613,846 acre-feet on behalf of the State of Nevada. The AWBA firms water supplies for Central Arizona Project municipal and industrial subcontract holders and communities along the Colorado River. As the agent for the State, the AWBA is responsible for meeting the State's Tribal firming obligations under the Arizona Water Settlements Act of 2004. The AWBA also assists with meeting the State's water management objectives under the Groundwater Code and provides the mechanism for interstate water banking with the other Lower Basin States. By storing water, the AWBA helps to ensure long-term water supplies for Arizona and neighboring states.
