Portable water tank
A portable water tank is a temporary collapsible tank designed for the reserve storage of water in firefighting, emergency relief, and military applications. These tanks can be either supported or unsupported. The supported tanks have a steel or aluminum frame and range in size from 600 to 5000 US gallons or larger by custom design. Portable water tanks are also unsupported such as self-supporting tanks (onion tanks), blivets and pillow or bladder tanks and are available in sizes ranging from 100 US gallons (380 L) up to 80,000 US gallons (300,000 L).
Usage/Deployment
It is primarily used in rural areas where fire hydrants are not available. They are carried on water tenders and are deployed at the scene of a fire during a shuttle operation. A portable water tank is usually set up near or front of an attack engine.[1] , or possibly next to a supply engine.[2] This enables tenders to quickly drop off their load of water and return to the fill site as soon as possible. They are designed to be set up in around a half-minute with two firefighters.The engine may then use suction hose to draft the water in the tank.[3]
