Central Arizona's Irrigation District Secures More Water Supply from Mojave Aquifer
Central Arizona's Innovative Water Supply Agreement
On July 4, 2026, the Central Arizona Irrigation and Drainage District (CAIDD) announced an exciting partnership with Cadiz, Inc. This collaboration aims to secure a stable water supply for the future, amid ongoing challenges posed by prolonged drought conditions in the region.
A New Era in Water Supply
The newly signed Memorandum of Understanding (MOU) allows CAIDD to purchase up to 10,000 acre-feet per year from the Mojave Groundwater Bank, located in San Bernardino County, California. This agreement marks the first of its kind between a California aquifer bank and an Arizona water district, demonstrating innovative cross-state water management.
With the Colorado River’s water deliveries diminishing due to prolonged drought and increased demand, this agreement offers an essential lifeline to agricultural producers and communities in Arizona, which rely heavily on this critical water resource.
Supporting Agriculture’s Future in Arizona
CAIDD plays a crucial role in the state’s agricultural landscape, serving about 87,600 acres of irrigated farmland in Pinal County. The recent MOU ensures that farmers within the district will have reliable access to supplemental water supplies. Derek McEachern, CAIDD's general manager, articulated the district's growing need for new water sources, emphasizing the importance of maintaining agricultural productivity and supporting rural communities.
Moreover, the MOU aligns with initiatives from the U.S. Bureau of Reclamation aimed at enhancing water management practices in the Colorado River Basin. This collaboration seeks to leverage legal and operational frameworks to facilitate interstate water transfers, thus addressing water scarcity innovatively.
Collaborative Efforts for Water Resilience
The dialogue surrounding this agreement has drawn attention from various stakeholders, including state officials and industry experts, who highlight the pressing need for sustainable water solutions in Arizona. Notably, Steve Montenegro, Arizona House Representatives’ president, emphasized the innovative potential of the Mojave Groundwater Bank. He noted that these types of projects are pivotal in supporting Arizona’s high-tech industries and agricultural outputs—both vital to the state's economy.
The terms of the MOU stipulate that CAIDD will have the rights to purchase the stipulated amount of water for an initial period of 50 years, with an option for renewal. The pricing structure includes a volume charge along with operational and transport costs, making it a feasible solution for resource expansion.
Environmental and Economic Implications
This strategic water agreement not only enhances water reliability but also supports an adaptive approach to Arizona’s water management challenges. As Susan Kennedy, president and CEO of Cadiz Inc., stated, the future of the Colorado River Basin hinges on new water supply developments rather than merely managing scarce resources. Through initiatives like this, Arizona is taking proactive steps to safeguard its water supply for generations to come.
The Mojave Groundwater Bank is anticipated to eventually provide over 2.5 million acre-feet of supplemental water to the Colorado River Basin, with significant contributions expected to come from CAIDD's agreement. The project already holds permissions for the delivery of about 50,000 acre-feet annually, indicating a scalable solution to regional water scarcity issues.
Conclusion: A Path to Sustainable Water Solutions
In conclusion, CAIDD's partnership with Cadiz Inc. embodies the essence of long-term planning and collaboration in addressing water scarcity. As Arizona faces ongoing challenges from climate variability and population growth, harnessing innovative water supply solutions like the Mojave Groundwater Bank will be essential in maintaining water security for both agricultural and urban needs. This agreement is not just a contract; it represents a commitment to sustainability, growth, and resilience in Arizona's water management framework.
