The self-supporting frameless onion tanks have been designed to meet the most stringent requirements for environmental spill cleanup. Problems with inadequate or unusable supplies of water are eliminated by the use of open top self-supporting portable water tanks. In remote areas the self-supporting tanks are designed for standby water containment, oil spill cleanup or other Haz-Mat spills. In remote areas, the self supporting tank may be filled by pumping water from a natural water source, such as a stream or creek, with a small gas operated pump. As the self supporting tank begins to fill with liquid, its unique design allows it to become self supporting automatically. The self supporting tank does not require any additional supporting framework, assembly, or frame installation.
