The Onion Tank is a self supporting tank that just needs a small staging area and minimal labor for set up. These tanks make excellent remote site water storage tanks and can be fully closed for safety. Onion tanks have a small footprint and are compact in size when not in use. Easy to transport to the staging area, the tanks are widely used in off the grid operations where hard-sided tanks cannot be placed. Need more information? Call us at 800-247-3846.
