Dewatering Tubes and Bags Sizing

Dewatering to Remove Sediment

dewatering tubeQuestion: I need dewatering bags to remove sediment. Can you tell me how big a bag I would need if I was thinking of removing 1,000 cubic yards of sediment?

Answer: When consider the correct geotextile bag sizing for your locations, there are several different factors we would need to know. As a general guideline, the largest sediment control bags that we offer are 15' x 25'; this offers a capacity of 15 cubic yards. Since you require storage for significantly more sediment, dewatering tubes are the best option.

Dewatering tubes, or geotubes, can be as large as 250 feet in length and 90 feet in circumference. They are capable of holding a significantly larger amount of sediment and dewatering materials.

There are several factors to determine the best sizing and dewatering option for your location.

  • Type of Sediment Being Contained
  • Percent of Solids in Situ
  • Goal Percent Solids
  • Polymers (will they be used, if so, how?)
  • Disposal Methods
  • Available Space

With the specifications of the project determined, you can decide the right geotextile bag for your situation.
