The OPENTANK onion water tank is in circular shape. It is composed of an inflatable or foam float.
In contrast to the closed flexible tank, this open storage solution allows for quick storage of raw or drinking water by its top opening. Thanks to its fast installation and pumping/filling and its light weight, it can be used in a punctual way. Moreover, it is foldable. Therefore takes up very little space. It is also very easy to clean in case of water pollution by sludge, leaves, sand etc..
This open top water storage tank has been primarily designed for :
The storage of raw water dedicated to civil security. This solution is widely used by firemen to fight forest fires. Helicopters carry bambi buckets that will fill up quickly by dipping them into our open top water storage tanks.
And the storage of drinking water dedicated to humanitarian organizations.
However, this Onion Water Tank can also be used for the storage of industrial effluents or polluted water.
Like our other flexible tanks, it is made of highly resistant PVC coated fabric (1300 gr/m2) and assembled by high frequency welding. This fabric is resistant to any temperature from -30°C to +70°C.
In the same register, we find the VOLUTEX water retention tank. This is an open top flexible tank dedicated to the storage of all types of solid or liquid elements for a temporary or permanent period.
