Foldable Water Storage Tank

Onion tanks, also known as collar tanks or bladder tanks, are frameless, self– supporting tanks with the shape of an onion. These tanks come in handy for the storage of water and other liquids in an emergency where tanks are needed within a very short time. These tanks are easy to set up and can be ready for use in about 10 or 15 minutes. Our onion tanks are equipped with an innovative self- raising and floating collar mode of closed-cell foam for easy filling. This makes the tank ideal for emergencies like fire fighting, disaster relief, spill containment, military operations, and many more.

Users can easily empty and neatly fold the tanks for storage and transport to and from the site. Though flexible, these tanks are made with heavy-duty fabrics for durability, even under tough climatic conditions. If you are worried about water contamination from outside sources, you can choose an onion tank with a top cover made of strong material.
