TenCate Geotube® Dewatering System

TenCate Geotube® dewatering technology is a simple, cost-effective system dewatering system. This proven technology can accommodate dewatering and containment in one, cost-effective operation. As the water drains, the solids continue to densify and consolidate over time. Once the solids are fully consolidated or have met minimum requirements for transport, several options are available for disposal of the dewatered material.Geotube® containers are available in a variety of sizes, depending on your volume and space requirements. TenCate Geotube containers use an engineered textile that is designed for dewatering of high moisture content sludge and sediment. TenCate Geotube® systems can even be mounted in mobile roll-off containers that can be transported around your property as necessary. It’s one of the most versatile dewatering technologies available. And one of the most effective. Standard tube sizes are available but they can be manufactured to suit project requirements.


  • Highly effective technology that produces high volume reduction and retention of solids
  • High effluent discharge rate with clear filtrate that can be recirculated through the system
  • Custom-sized containers saves expensive and limited land space
  • Easy removal and disposal of solids
  • Efficient, versatile and environmental friendly solution reduces carbon footprint
  • Reliable in all weather conditions and reduces risks in operational safety
  • Cost effective, low maintenance and saves time

How TenCate Geotube® Technology Works?

Dewatering with TenCate Geotube® technology is a three-step process:

Step 1: Filling

Sludge (slurry material) is pumped into the TenCate Geotube® container. Environmentally-safe polymers are added to the sludge, which makes the solids bind together and water separate. The TenCate Geotube® container’s unique fabric confines the fine grains of the material.

Step 2: Dewatering

Clear effluent water simply drains from the TenCate Geotube® container through the small pores in the specially engineered textile. This results in effective dewatering and efficient volume reduction of the contained materials. The volume reduction allows for repeated filling of the TenCate Geotube® container. Over 99% of solids are captured, and clear filtrate can be collected and recirculated through the system. The decanted water is often of a quality that can be reused/returned for processing or returned to native waterways without additional treatment.

Step 3: Consolidation

After the final cycle of filling and dewatering, the solids remain in the bag and continue to densify due to desiccation as residual water vapor escapes through the fabric. Volume reduction can be as high as 90 percent. When full, the TenCate Geotube® container and contents can be deposited at a landfill, remain on-site, or the solids can be removed and land-applied when appropriate.
