Mitchell Ag Investments Irrigation System Improvements 2018-2020
Primary Water Source: 8” Well. Depth 624’ Static water level 161’. The well has been tested with an estimated flow of 280GPM at 494’ drawdown. The well is projected to provide 300-320GPM at 588’.
Primary Pump Station at Well Site: Includes 60HP Submersible pump set 588’ in well on 4” galvanized pipe, with 588’ of 2/4 flat jacket electrical wire, heavy duty discharge elbow and 2 6” ductile iron check valves. Above ground appurtenances include ultrasonic water depth monitor, flow meter, 2 above ground check valves, three isolation gate valves, pressure relief and air vents and a chemigation inspection port. There is a 50HP booster pump above ground to supply additional pressure for the upper blocks. The control system is a custom duplex Variable Frequency Drive combined with a Soft Start panel to mitigate any well condition and variable pressure requirements. The pump station is mounted on a concrete pad with reinforced rebar, 6” deep with 12” stem walls.
Mainline installation to Utility Building Site: Includes installation of 1140’ of both 6”and 3” 200PR rated PVC in a common ditch, along with #12- 7 conductor safety control with in conduit.
