Dewatering bags are designed to filter sediment, silt and sludge on site and broadly in field operation. By pumping water into the bag, silt, dirt, sand and other pollutants are trapped and filtered so only water escapes to the ground below. The dewatering bags provide a simple yet effective method of removing heavy particles (>90 microns) from excavation water. Dewatering bags use inward pressure to provide enclosed dewatering without the need of a support container. The dewatering bags are sewn with high strength thread, providing proven durability and reliability in the field. These bags are available in any size by custom order.
