Frame Tanks & Decon Pools for Emergency Water Storage
Folding Frame Tanks and Quick Erect emergency water storage tanks (QET's) are easy to erect, supported tanks which are stable and designed for use on varied terrain. Their ability to deploy and setup in minutes has made them a favorite for firefighters, HAZMAT responders and oil spill recovery operations.
These emergency water storage tanks are also used as gray water storage and treatment stations at disaster recovery centers or military sites.
Typically each tank is supplied complete with all fittings, ground cover, pipes and rails. Standard product use and assembly instructions are included.
Typical Options:
- Fabric (compatibility to MSDS)
- Cover
- Fittings (Camlock, Ball valves, Flange)

Decontamination Pools
Our Portable decontamination pools are ideal Emergency personnel and HAZMAT use where response time is critical. Ideal for wash down areas, for the decontamination of people or equipment. Portable emergency water storage units are supplied with inflatable air chambers or soft memory foam filled sides. The air filled is our most popular due to the small storage footprint. These have also been purchased for Mud Wrestling events and fishing promotions!!!!
Our Standard emergency water storage tanks are sized from 50 to 50000 gallons and made from PVC, Urethane and Rubber. We do offer custom designed portable tanks- ask a member of our team what we can do to help.
