Geotube ® Dewatering Technology


A Geotube® container is a geotextile dewatering solution made from specially designed, dual filament, polypropylene fabric and is fabricated to the requirements of each specific project. Geotube ® technology provides a simple, low maintenance, and cost effective solution for the dewatering needs of many industries.


Geotextile dewatering technology works in three stages: containment, dewatering and consolidation. View the video below to see how Geotube® works.



As the sludge is pumped into the geotextile container, it is chemically conditioned to help the solids separate from the liquid.



Dewatering begins immediately and the filtered effluent begins to flow through the special material of the container, while the fabric liner keeps the solids trapped inside. The filtrate can then be directed to a lagoon, or another wastewater treatment facility. The remaining solids inside the container retain up to 100% of chemicals and metals.



During the consolidation stage (typically two to twelve months), the volume of solids inside the container decreases due to dewatering and composting. At this time, consolidation is complete, and the sludge can be used in landfills, and possibly as topsoil.

Our Geotube ® has several features that makes it stand apart from other geotextile containers.

GP-4 Port

This is an innovative connection to improve and simplify filling your Geotube® container. While the filling port can be a weak point in other designs, the GP-4 Port is comprised of 1″ thick inside and outside flange rings that sandwich the GT500 textile between 1/8″ thick rubber gaskets and is secured with 5/8″ bolts. This increases the operating safety during pumping.

Circumferential Seaming

This patented seaming reduces the stress on the seams which allows for higher pumping heights and a higher factor of safety than longitudinal seams. When a geotextile container is being filled, the greatest stress goes across the fabric from side to side.  When longitudinal seams are used, the stress is pulling the seams apart as it is being filled. Circumferential seaming also allows for any circumference to be created without introducing additional seams.
