Flexicube Applications

cube tankDrinking Water Storage: Manufactured with the same potable materials as our drinking water pillow tanks, the flexi cube can be built to store drinking water materials around or outside of your site. These cubes can offer you large capacity liquid storage in a tank that will not take up all your floor space.

Grey Water Storage: The flexible cube tank can be used to store types of grey water such as unfiltered water for supply to fire sprinklers, lawn sprinklers, or even laundromats. Their unique design helps them to fit in somewhat uniquely sized storage locations.

Rainwater Collection: As with many of our tanks, the flexi cube tank is perfect for rainwater collection from downspout filters and other piping devices.

Military Liquid Storage: The Lifeliner CUBE storage can be used for military fuel and water reserves. They help to resupply small bases with potable water and diesel fuel.
