"Delta Tube"
-Portable special levee-
Easy to install and economical. Lightweight and convenient "flood prevention tool" that replaces sandbags.
The portable special levee “DELTA TUBE (triangular water bag)” is a long triangular bag made of highly waterproof sheets. It is stretched and laid on top of the dike and water is injected into it to prevent overtopping of water from the dike.
As a flood prevention tool that replaces conventional sandbags, it is lightweight, folds compactly for storage and transportation, and can be set up quickly. They are also watertight to prevent overtopping and flooding, and are environmentally and resource friendly.

Delta Tube” mechanism, a triangular water reservoir
The performance of the Pelican case is utilized in a waterproof battery that can be used indoors or outdoors without worry, allowing for use in the rain.
A shoulder belt (MGB-1000C-AC02) and casters and carrying handle (MGB-2500C-AC01) are attached to the main unit, making it easy to move and carry the unit to locations where power is required.
Easy to follow and quick to install
Using a water injection hose, the system can be set up by a small number of people in a short time, requiring no extra labor, and can respond quickly to a sudden rise in water levels.
Compact and easy to transport
The lightweight, flexible tarpaulin allows it to be folded compactly and takes up little space for storage. It is also easy to carry.
Economical for repeated use.
It can be used repeatedly for about 10 years with maintenance. Since water from rivers or fire hydrants is injected for laying, no preparation of filler material is required, as is the case with sandbags. After use, it can be drained and reused.
Comparison of installation time of sandbags and “delta tubes
The standard “DELTA TUBE” can be installed in one-fifteenth the time compared to sandbags.
