Husky Self-Supporting Onion Tanks: The Frameless Solution
When a temporary liquid storage solution is needed, but manpower and space are a concern, our self supporting onion tanks are the perfect answer. Also known as pumpkin tanks or onion water tanks, their unique frameless design allows for a seamless, one-person setup. A heavy-duty foam collar rises as the tank fills, so there's no assembly required—just unfold and go. This innovative feature makes it one of the easiest and most reliable portable tanks for rapid deployment, freeing up valuable personnel for other critical tasks....

At Tank Depot, we offer a full line of these trusted tanks from Husky Portable Containment, with capacities ranging from 250 to 20,000 gallons. Whether you need a low-side tank for easy dumping in water shuttle operations or a high-side model for bucket dipping in forest fire operations, we have a solution built for the challenge. Our tanks are available in durable PVC and high-performance EXLON® materials, ensuring you get a robust tank that can withstand the demands of any emergency or industrial application.

Key Features of Onion Bladder Water Tanks for Rapid Deployment

Choosing between an aluminum folding frame tank and a steel folding frame tank is a critical decision that depends entirely on your operational needs. Both options feature the same durable, 22oz vinyl liner, but their frames are built for different purposes.
