Approximate Distance Feet Meters
Approximate Elevation Feet Meters

7) Do you prefer electric motors or diesel engines to drive the pump? Electric Diesel

8) How will you feed the washplant?

Excavator/ front end loader.  
Hopper/ Feeder. Quote Feeder? Yes No
Dredge Type of Washplant Land Based Floating
