Flexible Tanks and Water Bladders

Chatoyer Flexible Tank blue PVC

Flexible tanks (bladders) are used to store, process or transport liquids such as drinking water, emergency water, waste water and chemicals. They are economical and easy to use.

Chatoyer manufactures larger capacity industrial and commercial bladders. These are the suitable option when standard rigid tanks do not fit or will not suit conditions of use. Because flexible tanks are portable and fold up for easy transport and storage, they are ideal when a work frequently changes locations and on farms, orchards or vineyards where water storage requirements may change.

Bladders are manufactured in standard and custom sizes. They can be made of various materials for storing potable water, chemicals or edible liquids.
