Pumped Water Bag

  • Dirtbag dewatering bag in use
  • Dirtbag dewatering bag filtering water

Dirtbag dewatering bags remove silt, sand, and other debris from pumped water on construction sites, ponds, dredging locations and more. This helps protect surrounding streams, surrounding property, storm sewers and other receiving waters from pollution in addition to minimizing erosion concerns. 

Each standard bag has a fill spout large enough to accommodate a 4” discharge hose. Straps are attached to secure the hose and prevent pumped water from escaping without being filtered. To increase the efficiency of filtration, place the bag on an aggregate or haybale bed to maximize water flow through the surface area of the bag. Dirtbag is full when it no longer can efficiently filter sediment or pass water at a reasonable rate. Flow and removal rates will vary depending on the size of Dirtbag, the sediment discharged, and the surface under the bag. Under most circumstances, a 15×15 Dirtbag can pass up to 500 gallons of water per minute.

– Dirtbag must be monitored at all times during use (over-filling may cause rupture)
– Flow and removal rates vary based on particle size / sediment composition
– To increase flow rate place Dirtbag on aggregate, straw bales, or other porous surfaces
– Dirtbag is full when it can no longer efficiently pass water at a reasonable rate

As bags are manufactured in our Richmond, VA location, custom bags can be designed with either woven or nonwoven geotextile fabrics. We can produce almost any size, dimension or fabric weight requested.
