Portable Water Bladder (Pillow/Layflat) Tanks



Bladder Tanks in operation

These collapsible water bladder tanks, often referred to as layflat or pillow tanks, have been developed especially for use in harsh conditions worldwide. There are two specifications, one for economic water storage and the second for heavy duty multi-site storage applications and water transportation.

The water storage tanks are extremely mobile and can be unrolled and used on any area of flat ground which has been cleared of debris.
