Dewatering Bags

What is Dewatering Bags?

Dewatering Bags are manufactured from non-woven geotextile cloths that filter sediment-laden water from dewatering procedures. Sediment-laden water is pumped into the non-woven geotextile fabric bag, allowing filtered water to pass through.

Dewatering bags, also known as dewatering sediment bags, silt bags, or sediment filter bags, come in various styles and sizes to fit your project.

Why Use Dewatering Bags?

In construction, draining swamps or low-lying areas is a common occurrence. 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 discharged into a storm drain.

Dewatering Bag is a cost-effective and efficient solution. Pumping water into the bag traps and filters silt, dirt, sand, and other pollutants, allowing only moisture to escape to the ground below or nearby storm drains.

Mechanism of Dewatering Bag

While pumping out the dirty water in draining swamps or low-lying areas, these bags trap the pollutants like dirt, silt, mud, and debris from the water and collect them. Thus, it allows only moisture to escape to the ground.
