At storm aftermath, you may want to dewater a site so that it’s clean and ready to use again. In this case, you don’t want to just normally dewater it and dump everything that blends with the water back to the water source. What if it contains oil or dangerous substance that may endanger people’s health or even life? This is when you need Ultra Dewatering Bag.
Ultra dewatering bag gets soiled, possibly polluted water pumped into the bag. Here the oil and sediment are retained, while water is allowed to exit clean. The bags comply with NPDES, 40 CFR 122.26 (1996) when used as part of Best Management Practice in Stormwater pollution prevention plans.
