From the City of Tucson Website - "Tucson’s allocation of Colorado River water is delivered to Tucson via the Central Arizona Project (CAP) canal. That Colorado River water is allowed to sink into the ground and recharge the aquifer in Avra Valley at CAVSARP and SAVSARP where it is stored for future use. It is then pumped to the surface and held in the Clearwell Reservoir before it is delivered to Tucson Water customers.".
