Geotextile Dewatering Tubes to Dredge a Private Pond

Michigan, USA

Question on a geotextile dewatering tube to dredge pond area: Hello, I have some basic questions about geotextile dewatering tubes. We are looking to dredge an 11 acre private pond that is filled with fine silt and muck. The pond is 10' deep at most, and we will probably only dredge half the pond mostly at the shorelines. We haven't done the engineering studies yet, but what does a typical geotextile bag cost? How much sediment can I fit in one, etc? We are really just trying to do some initial research so we can propose the idea to our homeowners committee.

Hi there! Thank you for contacting GEI Works. We would be more than happy to assist you in your Dewatering Tube research.

The cost and sizing for your geotextile tube will depend significantly on the size you choose for your dewatering tube, as well as the type of sediment you are looking to retain. As a general guideline, we have seen dewatering tubes made in the following sizes:

  • Lengths: 50 feet, 100 feet, 150 feet, 200 feet
  • Circumferences: 15 feet, 30 feet, 45 feet, 60 feet, 75 feet, 90 feet

As you can see, these tubes can be made in sizes that are quite large and can hold a significant amount of sediment. Choosing the correct size for your location can depend on several different factors including:

  • Available Space
  • Pumping Rates
  • Type of Geotextile Fabric


Filling a Dewatering Tube

geotextile tube in waterThe sludge / sediment dewatering tubes are normally filled to 85% with slurry mix capacity and then allowed to consolidate. Once consolidation has taken place the dewatering tubes are then refilled, and the cycle continues, until the capacity 85% of consolidated solids is reached. The geotextile dewatering tubes should be left in left in-place to dewater over a period of time to achieve the best volume reduction.

Reduction rates depend on slurry, organics and conditions. Once consolidated the tube material can be trucked to off-site location for disposal or used as fill, compost or other beneficial uses.

Other Options used with the Geotextile Dewatering Tube to Dredge Pond:

Depending on the media, pump rates and site limitations we may consider using polymers to improve floccing and dewatering times. Additional items to consider when planning a sludge tube program is all the necessary dredging, pumping, and piping systems (The sludge / slurry flow to the tubes must be controlled through a series of manifolds and valves).
