Some of our dredges can pump up to a mile, but 1,000 to 2,000’ feet is a more common distance for efficient pumping. Different dredges pump sediment and muck in varying volumes and distances based on sediment type (sand/silt/clay content, abrasiveness, gravel, etc.). Dredging is not a one-sized fits all application. River Sand also has different types of dredges including auger cutterhead, hydraulic cutterhead, swinging ladder, cable operated, remote controlled, and aggregate/sand dredges. The most common sized dredges we utility are 6”, 8”, 10”, and 12” size pumps. We have dredges that are small one-man, diver operated systems up to large dredges that must be trucked in multiple tractor trailer loads and assembled with a crane. Hydraulic dredging or sometimes called pump dredging is a floating barge that vacuums the sediment from beneath the water’s surface and pumps it via a pipeline to a location for disposal or dewatering.
