Patch Call: Central Arizona Project Protective Services Department
The Central Arizona Project (CAP) is the largest and most expensive aqueduct system ever built in the United States. The 336-mile system delivers about 490 billion gallons of water from the Colorado River to central and southern Arizona each year, serving more than 5 million people—over 80 percent of the state’s population. CAP Protective Services agents are certified state peace officers tasked with safeguarding the project, its employees, and the public. Their service patch depicts the meandering CAP aqueduct transporting Arizona’s water, surrounded by a cactus, desert, mountains, and blue sky, all of which reflect the state’s natural beauty.
