Although pumping out water is a common and necessary construction activity, it can cause stormwater pollution if not done carefully. The D-Watering Bag is an effective device for separating sediment, silt, and debris from pumped water, making sure such contaminants never enter the storm drain system. The D-Watering bag attaches securely to the hose and is designed to accommodate a hose fitting up to 7” in diameter. Made from a nonwoven polypropylene geotextile that is both tear and UV resistant, you can count on this bag to get the job done.
