Dewatering silt bags are the easiest, most commonly used solution when cities and other municipalities need to remove sediment or sludge from public lakes and ponds. By pumping contaminated water directly into the large dewatering bags, all silt stays in one place for quick disposal, while clean water stays on site.
Each silt bag can hold between 1 and 15 cubic yards of material, depending on sizing. Most options range from 4 by 6 feet to 15 by 25 feet. They are typically placed on the ground in the dewatering area but can also be kept on trucks for easy transportation. Custom sludge dewatering bags are also available. However, for particularly large county projects, dewatering tubes are recommended.
