Dewatering silt bags are widely known as effective BMPs for removing sediment or sludge from construction sites and processing ponds. Pump contaminated water directly into large dewatering bags and gravity does the rest, with the clean water flowing out of the silt bag leaving the sediment behind. Easy to install and use, these sediment bags are perfect for storm water runoff, dewatering, or filtration. Silt bags for dewatering make sure the silt stays in one place for quick disposal.
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 dewatering projects, dewatering tubes are recommended.
