Onion Self-Supporting Tanks

The Self-Supporting Tanks are self-rising circular “Onion” shaped reservoirs / bladders used for water storage, firefighting, and Disaster relief efforts. The self-rising / floating collar is made of either closed cell foam or air filled.

Many heavy duty fabrics are available for the construction of these liquid storage tanks, which can be used in many different environments, for bulk liquid storage and transportation. Problems with inadequate or unusable supplies of water are eliminated by the use of onion self-supporting portable water tanks. In remote areas these tanks are designed for standby water containment, water shuttling situations and provide a continuous portable water supply.
