Onion tanks are self-rising, self-supporting collapsible tanks that can quickly store and supply water during emergency events. Designed with an open top and easy access fittings, onion tanks can be moved and set up quickly to meet the needs of most rural areas and emergency water storage situations.
Emergency water storage tanks come in 250 to 10,000 gallons storage capabilities. Two types of open top onion tanks are available, high-sided and low-sided, depending on your application and needs.
Open water onion tanks can be used to store multiple types of liquids and come in different fabric options depending on what applications the tank will be used for. Collapsible Tanks can be used to store water, both gray and black, drinking water, recovered crude oil, jet fuel, firefighting foam, sewage, and other contaminants.
