What population does the CAP water serve in Arizona?

The Central Arizona Project (CAP) is a significant water resource that primarily serves the central and southern regions of Arizona. It is a complex system designed to deliver Colorado River water to a large portion of the state's population, primarily focusing on urban areas. The approximately five million people served by the CAP includes residents in major cities such as Phoenix and Tucson, as well as agricultural and industrial users. This water supply is crucial for meeting the demands of a growing population in Arizona, particularly in areas that are arid and where water resources are limited. This number reflects both the residential and commercial users that depend on this vital water source for their daily needs. The figure emphasizes the importance of the CAP in supporting the state's economic and social activities, illustrating its central role in Arizona's water management strategy.
