Tucson Water, which supplies water for the City of Tucson in Arizona, is currently constructing the Southern Valley Storage and Recovery Project (SAVSARP) in order to meet current and future water demands of its service area, which is rapidly expanding. SAVSARP will be permitted by SWCA and will include 200 to 400 acres of recharge basins, 20 to 40 recovery wells, a reservoir-booster station, and more than 25 miles of pipelines on the approximately 100-foot-wide x 8.5-mile-long pipeline corridor.
