This video show the steps taken through a hydraulic dredging project. This Hydraulic dredging project was completed in August 2017 in Swansea, IL. We removed close to 10,000 cubic yards of Sediment from 3 Coves. The Sediment was pumped into 60’x200′ foot dewatering tubes. Polymers were used to flocculate the slurry before it enters the bags to increase the speed of dewatering. The amphibious excavator was used to remove sediment from around docks and seawall where the hydraulic dredge would have difficulty maneuvering.
