Internal “baffles” are moulded into our Litre Flat Slimline tank to reduce water movement and increase stability during transportation. The baffles prevent the liquid sloshing from side to side, making the tank ideal for window cleaners, mobile car valeters, etc.

This water storage tank can also be permanently installed in a pickup, van or on a water bowser to provide water storage at your convenience. It is suitable for the storage of drinking water, while the slimline design offers space restrictive water storage in garages, farming buildings and behind sheds.
