Dewatering Bag Connections

I am looking for information on dewatering bag connections. What options do I have available? I have been using one of your dewatering bags and struggling trying to figure out how to connect a hose to them. I am afraid it will just fall right back out. Do you have any suggestions on how this might be done?

A dewatering or sediment filter bag is designed to contain sediment, sludge, and other material during a dewatering process. Due to their flexible design and construction, these bags have been made to accommodate several different hose connections up to 4 inches that might be found in your location.

  • 2" Discharge Hose
  • 3" Discharge Hose
  • 4" Discharge Hose

  1. Make an Incision Along the Edge of the Bag. This can be along any edge, but should be a small incisions just large enough to fit your hose.

  2. Insert the Hose.

  3. Clamp the Fabric to the Bag. This can be done using almost anything securing material including
    • Wires

    • Clamps
    • Ropes

  • Volume. Along these same lines, you will also want to make sure that your dewatering bag can handle the amount of sediment you expect to collect. You should consider the size, amount, and type of sediment.

  • Placement: If you are worried about the hose, you could also place the bag in a contained area such as a dump truck or drop box. This will help temporarily contain discharge if it comes disconnected, as well as ease the transportation process of your discharge materials.
