About

Central Arizona Project (CAP)

Central Arizona Project (CAP) delivers water to nearly 6 million people, more than 80% of the state’s population, in Maricopa, Pinal and Pima counties. CAP carries water from Lake Havasu near Parker to the southern boundary of the San Xavier Indian Reservation southwest of Tucson. It is a 336-mile long system of aqueducts, tunnels, pumping plants and pipelines.

YOUR WATER. YOUR FUTURE.

CAP 101

In central and southern Arizona there are few things more critical to our quality of life. Do you know where your water comes from?

HISTORY OF CAP

In the early 20th century, Central Arizona Project was a shared dream of Arizonans; a vision of water security and stability for future generations to enjoy their quality of life in a desert. Now that the 336-mile long water delivery system is a reality, the leadership of CAP is responsible for sustaining and managing what past generations were able to fund and build.
