Central Arizona Project (CAP)
is Arizona’s single largest resource for renewable water supplies. CAP delivers Colorado River water to Maricopa, Pinal and Pima counties. More than 5 million people, or more than 80% of the state’s population, live in Maricopa, Pima and Pinal counties, where CAP water is delivered. 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 and is the largest single resource of renewable water supplies in Arizona.
YOUR WATER. YOUR FUTURE.
In central and southern Arizona there are few things more critical to our quality of life. Do you know where your water comes from?
Background & History
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.

($2 trillion in economic impact since CAP deliveries began.) Take some time to KNOW YOUR WATER.
