Pinal Valley Recharge
and Recovery Facility

Through great collaboration on the Pinal Valley Recharge and Recovery Facility project, we installed a cast-in-place gravity turnout structure located in the CAP canal through a custom-designed steel cofferdam. Out of the turnout, we installed a pre-cast meter vault and 4,400 linear feet of 30-inch ductile iron raw water gravity pipeline.  The pipeline runs to our 70,000 cubic yard excavation that creates the recharge basin itself.  The basin is fed the pipeline via two precast valve vaults that house motor actuated plug valves for monitoring the flow.  The basin has twenty-two 60-foot deep drilled bore holes that will serve as the conduit for the CAP water to recharge the water table.  The flow meter and motor actuated plug valves to CAP’s SCADA system allows Arizona Water Company to control the flow into the basin remotely.
