1. Drilling, casing, gravel packing, and yield testing of a 36” diameter water well approximately 50 ft deep at location “well 2” on the map that is Appendix 1. This well must be drilled with a reverse rotation drill rig or similar technology to ensure maximum possible water yield of the resulting well. Provide and file well drillers report upon completion.

2. Submersible pump, check valve if required by pump manufacturer or state of Kansas regulations, and all necessary wiring to be installed at the well from item 1 above, see addendum for electrical scope. Pump must be capable of delivering 300 gallons per minute at 100 psi at the furthest outlet of the pipeline. Connect finished well and pump system to irrigation line.

3. Tier IV Diesel irrigation engine, 74hp. JD PowerTech EWX 4045TFC-03 or Equivalent with

Radiator cooling group or Equivalent to replace the aged engine at “well 3” on the map in Appendix 1. Salient physical and performance characteristics include 74 hp @ 2200 rpm, continuous horsepower @1800 rpm is 66 horsepower, Cooling Package, Murphy control, TwinDisc PTO, Flange to connect to existing pump.

4. 4800 ft -6” IPS, solvent weld bell end or gasketed joint PVC pressure pipe, SDR 26

160psi, must meet ASTM D2241 certification installed as delineated on map following all requirements in the attached construction specification . Final layout of pipeline may vary from map to accommodate avoiding utilities and septic system but final quantity of pipeline is fixed. Must be installed in accordance with NRCS-Conservation Practice Standard and Construction Specification 430, attached.

5. 11 – 6” x 6”x4”PVC “Tee” fittings at risers, mechanical joints and 11 -4” 90 degree galvanized steel fittings, 11 risers to extend 12” above ground surface, must be 4” galvanized steel, 11-4""aluminum riser valves, 1 pressure relief valve to protect pipeline from bursting, 4 combination air/vacuum valves. See riser detail sheet.
