Geotextile Tubes for Lagoon Sludge
Collection of Filtered Runoff
Question: I am looking for lagoon sludge removal tubes. I have a lagoon that is full of sludge, and I need to dewater it. I saw that you have dewatering bags as well as larger dewatering tubes. How is the water collected outside the bag? We are currently sending 20 truckloads of material to a lagoon.
Answer: The collection and distribution of your lagoon can depend on the type of sediment or sludge you are collecting out of the tube, as well as where you plan to place this water. Typically when dewatering a site or lagoon, sediment will be stored inside the tube while filtered water is directed to a retention area or reservoir.
Filtered Runoff from Geotextile Dewatering Tubes
Depending on your location for sludge dewatering, filtered runoff from geotextile tubes can be directed to several possible locations.
- Reservoirs or Retention Areas: As mentioned above, a common method is directing filtered water to a designated reservoir or retention area. This can be done through the use of berms and dewatering tube placement.
- Back into the Lagoon: If you will be dewatering next to your lagoon, another common method would be to direct the water back into the lagoon. Typically during any dewatering tube project, a ground liner or berm is placed underneath sludge tubes to help direct the water to its intended location.
- Inside Dump Containers: Depending on the size of your lagoon sludge removal project, the geotextile tubes can also be placed directly into a large dump truck or container. Water can then be drained from these containers into desired areas.
Geotextile Tube Construction
The construction of sludge tubes includes several components that help to easily operate and fill your sludge removal equipment. Standard features for these geotextile tubes include:
- Polypropylene Woven Geotextile Material
- UV Stabilized
- Typical Circumferences: 15, 22.5, 30, 45 or 60 feet (larger circumferences can include units up to 75 or 90 feet)
- Filling Ports: Varies from one to five (1 to 5) based on the length and volume of your tube. There is one port for every 50 feet of length.
- Typical Lengths: 50, 100, 150, 200, or 250 feet (other lengths available on request)

Use with Polymers to Improve Filtration Rate
Particularly when dealing with sludge dewatering, many customers choose to use polymers or flocculent to help improve dewatering times and treat the sludge coming from their lagoon. Depending on your specific area conditions, contacting a polymer specialist can be a good choice for this type of dewatering process. Polymers are often mixed directly into the sludge removal equipment.
