FAQ What are dewatering bags? Dewatering Bags, also known as sediment filter bags, are bags used to filter sediments, silt, sludge and other pollutants from water pumped into them. They are used for cleaning water from construction sites, ponds, and dredging locations. Are dewatering bags reusable? Dewatering bags can be cleaned and reused, but we do not recommend this as a best practice. How do dewatering bags work? Dewatering bags work by cleaning the dirty water that’s being pumped into them from an outside source, such as a pond. Because the bags are made from a non woven geotextile fabric, which acts as a filter, the water is allowed to pass through but not the larger more solid materials: sediments, silt, sludge, etc. Why do we need dewatering? Dewatering is needed in construction and dredging. It’s needed in construction to ensure the longevity of the building project by helping to stabilize soil and protect against erosion. It also contributes to worker safety and efficiency. Dewatering is needed in dredging to protect wildlife by filtering out water pollutants, as well as ensuring an appropriate depth of water in channels and anchorages for the safe passage of boats. To accomplish these tasks sediment dewatering bags are usually a popular choice.
