Onion tanks are designed for on-going use and last a very long time when well looked after. They are designed to be portable tanks that can be transported while empty and easily relocated. They are not designed to transport water. If you are looking for these tanks, please check our tanks.
These tanks can be used to store recovered hazardous materials, like oil from oil spills via pumps and skimmer systems, chemicals, emergency water storage or for other liquids. The self supporting tanks are manufactured with outriggers and provide stability even on uneven terrain.
