UltraTech 9729-OS Ultra-Dewatering Bag® Dewatering Bag, For Use With Storm Drain, 90 gpm/sq-ft Flow Rate, 12 cu-ft Capacity, Non-Woven/Polyethylene Geotextile

Draining swampy or low lying areas is a common occurrence in construction. Unfortunately, pumping out the water from these areas also removes 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.

• Retains both oil and sediment, offering a combination of benefits not available in alternative dewatering bags
• Accommodates up to 4 in discharge hose
• Helps comply with NPDES, 40 CFR 122.26 (1999) when used as best management practice in storm water pollution prevention plans
