The CAP is a 336-mile canal system stretching from Lake Havasu to Tucson, and includes pumping plants, check gates, and turnouts – but exactly what area of the state does CAP serve?
The answer: This system reliably delivers Colorado River water to CAP’s service area, which is comprised of Maricopa, Pinal, and Pima counties.
That’s a 24,000-square-mile area in central and southern Arizona where nearly 6 million people live, equating to approximately 80 percent of the state’s population.
Bonus facts: CAP is a water wholesaler that delivers untreated water to approximately 60 water users which fall into three user groups – municipal and industrial, agricultural, and Native American tribes.
