Depend on Our Agile Dredging Equipment
Clean Channel Dredging uses a uniquely portable sediment-removal system designed to perform jobs inaccessible to other equipment. Mobilization costs are a fraction of those of heavier machines. The launching and loading is more like a boat than a conventional dredge or excavator, and there is no damage to the shoreline or tracks to be repaired.
Weighing only 3800 pounds, the hydraulic dredger is mounted on an 8-foot-wide pontoon and used to clean channels, sediment lagoons, marinas, golf course ponds, and home association lakes. Sediment is excavated by a durable, direct-drive cutter head, and discharged at up to 1600 GPM through a highly abrasion-resistant, hydraulic submersible pump. Floats and hydraulic tubing are stainless steel, with an abrasion-resistant (400 brinell) steel pump. Once in place, the dredger moves across the water using an automated windlass and cable set.
Choices on Sediment Disposition
The wet sediment can be “pumped and dumped” immediately through auxiliary hoses. Or choose to pump the wet sediment into geotextile dewatering bags to reclaim and redirect clean water back into the channel, lake or pond. Clean Channel Dredging works with the community to determine the best choice and, if dewatering is the option, the optimum location and size of these sediment filtration bags.
Dewatering starts as soon as pumping begins, and typically takes just a few weeks for filtration to complete. Once dewatered, the soil is ideal for fill dirt. Since soil erosion is the main culprit behind sediment problems, there are often many areas needing backfill. Clean Channel Dredging can include soil disposition as part of our services, such as embankment, fill pile locations, topsoil pile locations, haul roads, erosion and sedimentation control. Typically, soil transportation requires a couple of weeks. If Clean Channel Dredging coordinates, we will bid and provide earth-moving equipment and labor as needed.
