Pond dredge silt disposal12/6/2023 These excavators allow for removal of sediment all the way across many ponds and lakes. Long reach excavators have extended booms capable of 50-70’ in length. The best solution is a special excavator built for dredging, called a long-reach excavator. Futhermore, limited sediment can be placed next to the excavator because it is typically very wet and runs back under the excavator tracks. As you increase the depth the bucket moves closer and the length decreases dramatically. The issue with 15-25’ is that it is the maximum dredging if you were straight out. Small mini-excavators typically reach up to 15’ horizontally and larger excavators can increase the length up to 25’. Mini-excavators, midi-excavators, and large excavators all have different bucket sizes, weights, and length of reaches. Excavators are available in many different sizes. River Sand also provides disposal of the sludge as a turn-key solution.Dredging the sediment with an excavator is also an option. Disposal of alum sludge may be provided by the water treatment plant operator and in that case River Sand can provide any necessary trucking or support equipment. Geosythetic dewatering tubes require a larger footprint, flat area, and the timeframe for which the solids require for dewatering before the tube can be opened and solids ready for disposal. Using a belt press or multiple belt presses fit within a smaller footprint and produce solids that can be transported directly to be disposed. Both methods may implement polymer injection to achieve rapid dewatering results. Dewatering is typically accomplished with mechanical dewatering utilizing a belt press or alternatively with a dewatering tube. However, the removal of sludge is often relative to the dewatering capacity, and that is relative to many other factors within the project’s scope of work. Depending on the size of the dredge, it can pump up to 100s of cubic yards per hour which can be calculated to dry solids based on the density. A hydraulic dredge with an auger cutterhead can be set up within a pond or lagoon on a cable traverse system.
