CAP's service area is comprised of three counties in central and southern Arizona--Maricopa, Pinal and Pima. This 24,000 square mile area (approximately 20% of the state), includes 5.3 million people, which is some 81% of the state's population.  The service area also includes Arizona's three largest Active Management Areas (Phoenix, Pinal & Tucson) in which water is closely regulated by the Arizona Department of Water Resources.
