What is a De-watering Bag?

  • De-watering Bags are constructed of high strength woven geotextile and are custom fabricated with double stitching that resist pressures during pumping operations.

  • High flow rate allows liquid to dewater, while containing solids.

  • Average Sizing

    Length - 100ft                                    Circumference - 45ft
                - 200ft                                                             - 60ft


The De-watering Bag is pumped with sludge Material. As the liquid escapes from the tube, solid particles are trapped inside. The process is repeated until the tube is full. The dried solids will increase the options for transportation and disposal.

Potential De-watering Applications


  • Municipal Sewage Sludge
  • Pulp and Paper Mill Sludge
  • Fly Ash
  • Fine Grained Dredged Material 
  • Coal Tailings
  • Mining and Drilling Waste
  • Industrial By-Product Waste
  • Agricultural Waste

Placement of the De-watering Bags


De-water bag is laid across the berms after the surface has been prepared. After the ditch is constructed, a fiber mat is placed prior to laying the bag out.

Disposal of Solids


1. Sanitary Landfill

2. Land Application

Bag and fiber mat is disposed at sanitary landfill after solids has been removed and the distributed area is resloped and seeded.
