Pumped Water Bag
Dewatering bags remove silt, sand, and other debris from pumped water thus taking the complexity out of sediment control. Where traditional non-woven water bags fail, high-strength, high-flow pumped water bags are the answer. Furthermore, this solution is cost-effective for everyday site use and is commonly employed in environmental and coastal applications.
Dirtbag®
Dewatering bags, such as the Dirtbag, protect surrounding streams, property, storm sewers, and other receiving waters from pollution. Each standard bag has a large fill spout to accommodate a 4” discharge hose. In addition, straps attach to secure the hose. This prevents pumped water from escaping before it is filtered. To increase the filtration efficiency, place the bag on an aggregate or hay bale bed. This optimizes the surface area, therefore enhancing water flow. To note, flow and removal rates depend on the size of the dirtbag, sediment discharged, and the surface under the bag. On average, a 15×15 Dirtbag passes up to 500 gallons of water per minute.

What applications benefit from dewatering bags?
- Sediment control for pumped dewatering
- Consolidation of both sludge and other environmental remediation
- Revetment and basal reinforcement at dams and levees (when filled with solids)
How do dewatering bags work?
Dewatering bags capture sediment as water is pumped through the bag’s geotextile fabric. As the water flows out, the bag retains the solids inside. To use:
- Connect the pump discharge to the bag’s spout and secure it.
- Place the bag on a porous surface (gravel, straw, or hay bales).
- Monitor regularly and stop pumping when flow decreases—indicating the bag is full.
- Overfilling may cause rupture, so always monitor during use. Flow and sediment removal efficiency depend on sediment composition and fabric selection.
What key features and benefits do sediment bags or water pump filter bags provide?
- Available in both standard and project-specific sizes, including applications with multiple pumps
- High tensile strength seams prevent blowouts which are, in fact, the most common source of dewatering bag failure.
- Compatibility with flocculants: For higher performance in sensitive receiving waters, utilize it with the Interface H20 FlocHog and FlocLogs.
- Custom Dewatering Bags are available with either woven or nonwoven geotextile fabrics in almost any size, dimension, or fabric weight
