Dewatering Tubes for Dredging

Dredge Dewatering Considerations

dewatering tubeQuestion: We are looking for some dewatering tubes. We are planning to dredge a few ponds at our plant, and we would like to use the geotextile tubes. What considerations do we need to take?

Answer: The Dewatering Tubes, and occasionally the dewatering bags, are frequent choices for pond or lake dredging projects, offering an excellent way to filter out materials that get turned up during a dredge dewatering project. Anytime you are implementing a large dewatering project, there are several conditions to consider to choose the best size and setup for your location.

  • What Type of Materials are Being Dredged?
    • If possible, it is helpful to know the composition of your material, such as percentages of sand, sediment, or clay.
  • What Location are You Dredging?
    • Pond, lake, lagoon, waste stream, etc.
  • What is the Natural Percent Solids in Your Location?
    • Knowing what percentage of solids you have in your effluent helps determine fluidity and whether or not you will need flocculents to achieve proper dewatering.
  • What is the Target Percent Solids?
    • What does your site or project require as the target percent of solids in the effluent you need to achieve?
  • Where Will You Be Using the Tube?
    • This may include available space (width and length) as well as any slopes that may exist in your area.
  • What is the Pumping Rate?
    • This can be identified in gallons per minute.
  • Will You Be Using a Polymer?
    • During many geotubes dewatering projects, polymers are used to help increase performance times. If you are considering using one, a polymer expert should be contacted to help analyze your project and design the best plan for your location.

dewatering tubeDewatering tubes are highly reliable dewatering products that have been effectively used in the dredging of lakes, ponds, lagoons, and streams. Dewatering tubes are typically made from a woven geotextile filtering material. Individual specifications may vary depending on available space and the amount of sediment or material to dewater. The geotextile tubes are often used as an economical alternative to traditional dewatering equipment. Learn more about Geotextile Dewatering Tubes.

For smaller projects, silt socks or silt filter dewatering bags may be a better option. Navigate to our Dewatering Bags page to learn more.
