Frameless, Self-Supporting Water Storage for Remote Firefighting

This vetted Fol-Da-Tank SST is built tough for rapid deployment in remote wildfire operations. The frameless design becomes completely self-supporting as it fills, eliminating the need for heavy assembly or foot pumps. Available in 22 Oz Vinyl, 40 Oz Vinyl, or heavy-duty 22 Oz HPR liners, this commercial-grade tank handles rough terrain without fail. A smart investment for your fleet, it drains easily through a side fitting and collapses into a compact storage bag that fits in a fire truck or helicopter. Ships free.

Eliminate Frame Failure In The Field

Eliminate Frame Failure In The Field

The unique self-supporting design dissolves the single biggest failure point in portable water storage: structural frames. As this tank fills, water pressure itself becomes the support structure. No welded joints to crack, no assembly hardware to lose, no frame components that corrode or bend under load. This curated approach means one less thing that can go wrong when you're already dealing with wildfire conditions. The frameless construction removes an entire category of field failures that lead to spills, compliance issues, and costly downtime during critical operations.

Match Liner Material To Terrain

Match Liner Material To Terrain

Choosing the wrong liner for your operating environment turns a functional tank into a liability. The vinyl liner handles standard deployments, while the heavy duty HPR liner is engineered for rough terrain and sustained heavy use. This vetted selection process means you're not guessing at durability. HPR construction stands up to abrasive ground contact, sharp debris, and repeated deploy-and-pack cycles that would degrade standard vinyl over a single fire season. Select the material that matches your actual deployment conditions rather than hoping a one-size-fits-all liner holds up.

Deploy Anywhere, Store Anywhere

Deploy Anywhere, Store Anywhere

Remote wildfire operations demand equipment that doesn't fight your logistics chain. This tank collapses into a compact storage bag small enough to fit in the side compartment of a fire truck or the cargo bay of a helicopter. The special high sides maintain water volume during filling and helicopter dipping operations. When the operation moves, the tank moves with it, without requiring a dedicated transport vehicle. From water relay stations to retardant mixing sites to helicopter dip tanks, the same unit handles multiple roles, reducing the number of specialized containers your crew needs to manage.

Compatibility & Deployment

Ensure your deployment setup meets these requirements for optimal field performance.

  • Ground space must accommodate the filled footprint of the selected gallon size
  • Transport vehicle cargo area must fit the collapsed storage bag dimensions
  • Water source connection must securely attach to the side drain fitting

“We switched from framed portable tanks to the Fol-Da-Tank SST last fire season. Setup went from 45 minutes with a crew of three to under ten minutes with two people. The HPR liner held up through rocky ridge deployments without a single issue. This is the kind of craftsmanship that keeps your crew moving instead of babysitting equipment.”

The Fol-Da-Tank foldable Forest Service Water Tank is a portable, self supporting tank (SST) used by firefighters to fight forest fires in remote areas. Available sizes range from 250 gallons to 20,000 gallons.

The forest service tank is available in vinyl or heavy duty HPR (high performance rubber) liner.  The HPR liner is recommended for rough terrain or heavy duty applications. 

As the frameless water tank fills with water, the unique design allows it to become self supporting and stand on its own without the need for heavy frames. When no longer in use, the SST tank can be drained through a fitting on the side.

The tank is easily collapsible and is stored in a compact storage bag.  Store the folded up tank in the side or back of a fire truck or in the cargo compartment of a helicopter.
