Draining swampy or low-lying areas is a common occurrence in construction. Unfortunately pumping out the water from these areas also removed a lot of dirt silt mud and debris along with the water. These contaminants can cause problems if they are simply discharged into a storm drain. The Ultra-Dewatering Bag provides an economical and effective solution. By pumping water into the bag silt dirt sand and other pollutants are trapped and filtered so only water escapes to the ground below or nearby storm drains.Ultra-dewatering bag
