Frameless, Self-Supporting Water Storage for Remote Fire Suppression

The Fol-Da-Tank Collapsible SST Forest Service Water Tank is a vetted, portable reservoir designed for demanding firefighting operations. As it fills, the frameless design becomes completely self-supporting—eliminating the need for bulky assembly or foot pumps. Available in heavy-duty HPR or vinyl liners, this curated tank handles rough terrain with ease. It features special high sides and a convenient side drain fitting for rapid deployment. Stowing is simple; the collapsible design packs into a compact storage bag that fits easily in a fire truck or helicopter. Built tough for critical applications, this tank is a reliable investment for your fleet.

Frameless Design Eliminates Structural Failure Points

Frameless Design Eliminates Structural Failure Points

Traditional water tanks rely on welded frames and rigid structures that develop stress fractures and failure points over time. The Fol-Da-Tank eliminates this vulnerability entirely through its frameless self-supporting design. As water fills the tank, hydrostatic pressure creates structural rigidity without any framework, no assembly, and no foot pump. All seams are welded for leak prevention. This approach removes the weak points that cause conventional tanks to fail in the field. Whether you are running water relay operations or using it as a helicopter dip tank, this curated unit delivers reliable deployment without the failure modes that cost you downtime and money.

HPR Liner Handles Rough Terrain Without Compromise

HPR Liner Handles Rough Terrain Without Compromise

Standard vinyl liners work for controlled environments, but remote firefighting operations demand more. The HPR (high performance rubber) liner option is engineered for rough terrain and heavy duty applications where standard materials degrade. Available in 22 oz weight, this liner resists punctures, abrasion, and environmental exposure that would compromise lesser tanks. Tank Vault carries this option because field-tested performance matters more than shelf appeal. From hazardous waste containment to fire retardant mixing, the HPR liner maintains integrity under conditions that end the service life of conventional collapsible tanks. Choose the material that matches your operational reality.

Helicopter-Ready Portability for Remote Deployments

Helicopter-Ready Portability for Remote Deployments

A stationary tank cannot reach a fireline accessible only by air. The Fol-Da-Tank collapses into a compact storage bag that fits in the cargo compartment of a helicopter or the side compartment of a fire truck. This portability means your water supply arrives where rigid tanks simply cannot go. Sizes span from 250 gallons for rapid response to 20,000 gallons for sustained operations, so you scale capacity to the mission. Drain through the side fitting when the operation ends, fold, and move out. Every detail of this vetted design serves professionals who cannot afford to be anchored to one location.

Sizing & Compatibility

Ensure your deployment site meets these requirements for optimal operation of the self-supporting tank.

  • Site supports selected capacity between 250 gallons and 20,000 gallons
  • Transport vehicle cargo space accommodates compact storage bag dimensions
  • Ground conditions support HPR liner deployment for rough terrain applications

Primary Applications

“We switched to the Fol-Da-Tank with HPR liner last season for our helicopter dip operations. No frame to assemble, no foot pump, just unfold and fill. It fits in our Bell 206 cargo compartment without issue. After 60+ deployments on rocky ridge lines, the liner shows zero punctures. This is the first collapsible tank that actually lasted a full fire season without patching.”

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.
