Sludge / sediment geotextile dewatering tubes are filled to 85% capacity with slurry mix and then allowed to consolidate. Once consolidation has taken place, the geotextile tubes are refilled, and the cycle continues until consolidated solids reach 85% of the total capacity.

In order to achieve the best volume reduction, geotextile tubes should be left in place to dewater over extended periods of the time. Reduction rates often vary from site to site and depend on the slurry, organics, and conditions of a location. After the sludge or sediment removal process is done, consolidated materials can be transported to an off-site location for disposal or used as fill or compost.
