Barnard Construction Company, Inc.'s work on this multi-faceted Bureau of Reclamation water delivery project south of Tucson enabled the Tohono O'odham Nation to switch from the delivery of Colorado River water through an antiquated irrigation system to use of the 21.5 billion gallons of Central Arizona Project water the farm had been allotted annually under a settlement with the federal government. Water is now distributed through an underground pipe system to each irrigated field. The irrigation is controlled by electrical and telemetric systems. Barnard's earthwork involved excavating stormwater control channels to divert stormwater away from the farm. These channels are protected by a variety of erosion control methods, including riprap, gabions, soil-cement, concrete, and native vegetation. All of this work has reduced the water loss and erosion on the cooperative farm. In addition, the project entailed expanding irrigation to reach previously abandoned acres which can now produce alfalfa, vegetables, and mesquite and fruit- and nut-bearing trees. Barnard also improved farm access roads.
