The Dustpan Dredge is like a large vacuum cleaner. This type dredge is used on the Mississippi River. The suction head, approximately the width of the dredge, is lowered to the face of the material to be removed. High velocity water jets loosen the material which is then drawn by pump as a slurry through the dredge pipe and floating pipeline where the material is deposited outside of the navigation channel.
The cutterhead dredge is similar except for a rotating cutter which loosens the material to be pumped. This type of dredge is used for dredging tougher material that is found on the White River and harbors. Our dredging requirements are accomplished by both contract and government owned and operated dredges.
