Dewatering Bags


Draining swampy or low-lying areas is a common occurrence with construction projects. 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 serious problems if they are simply discharged into a stormwater drain.

The Greentec dewatering Bags are made from a high quality geotextile fabric which filter silt laden water from construction sites. As site water is pumped into the bag, sediment is collected by the geotextile fabric allowing filtered water to freely pass through.

The Greentec Dewatering Bag provides an economical and cost 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.
