Dewatering bags are used on construction sites in water pumping conditions so that sediment discharge is controlled during pumping. When water flows through the dewatering bag the sediment settles as the water is slowed by the bag and the bag captures the soil. These bags fit onto discharge hoses. They are also known as "Sediment Bags" or "Dirt Bags". The bags are made from heavy 8 oz. non woven geotextile fabric and the stitching is a durable double thread chain stitch. Typical applications include: Municipal wastewater, industrial pond pumping and dredging, agricultural waste pumping and dredging, waterway remediation and dredging, power plant cooling tower sludge and construction and plant turnaround projects.
