ZebraTube Dewatering and Containment

ZebraTube® dewatering bags offer a low cost, easy solution for sludge dewatering and containment.


Sludge is pumped or dredged from the wastewater source. The geobag acts as a filter, allowing water to pass through but trapping the solids inside.


Our hanging bags come with forklift handles for mobile dewatering. Projects with space on site use our tubes for efficient dewatering of large volumes. 


We supply for small and large operations across sewerage, mining, manufacturing, and food and beverage industries. Bags range from 1m to 50m.

What size do you need? Contact us for sizing and availability. You can buy our smaller geobags online.


ZebraTube® dewatering bags use woven polymer fabrics as semi-permeable membranes to trap the solids inside. Sludge is pumped in from the wastewater source, such as a settling pond. The geotextile acts as a filter, allowing water to pass through but retaining the solid matter for disposal.

Hanging bag setup for dewatering sludge

The dewatered sludge consolidates, reducing its volume and increasing solids concentration. This makes for easier, more cost effective disposal or further processing if needed.


Depending on the slurry, moisture contents between 40-60% are achievable in short dewatering times; even lower if bags are allowed to consolidate for longer periods.
