Our Transportable Water Tank collection is designed for professionals and individuals who need to move water safely and reliably. From mobile car valeters and window cleaners to farmers and event organizers, our range of baffled tanks and towable bowsers provides the perfect solution for on-the-go water storage. Unlike standard stationary tanks, these units are engineered to handle the dynamic stresses of road and off-road travel.
Safety is the most critical factor when transporting liquid. Water is heavy (1kg per litre), and its movement during transit can create a dangerous "surge" effect. Our transportable tanks feature internal baffles—structural dividers that break up the volume of water. This prevents the weight from shifting suddenly when you brake or turn, ensuring your vehicle remains stable and easier to control, which is essential for both small vans and large commercial trucks.
We offer a wide variety of configurations to suit different vehicle layouts:
Horizontal & Low Profile: Distributes weight lower to the ground for better vehicle handling.
Upright & Slimline: Perfect for saving floor space in the back of a service van.
Wheel Arch Tanks: Contoured to fit over the interior wheel wells of vans and campers, utilizing space that would otherwise be wasted.
Bowser Systems: Fully integrated tanks on trailers for either site-only use or road-legal highway towing.
Every tank in this collection is manufactured from high-density, UV-stabilized polyethylene using a rotational moulding process. This results in a heavy-duty, one-piece construction with no seams or joins that could fail under the pressure of moving water. Whether you need a non-potable tank for industrial pressure washing or a WRAS-approved potable tank for drinking water delivery, our products are built to withstand daily commercial use.
Beyond just the tank, The Tank Shop provides the accessories needed to create a full system. We stock mounting frames, outlet kits, and high-performance pumps that can be integrated directly with your tank. With over 20 years of experience serving the UK market, we can advise on the best setup for your specific vehicle and application, ensuring you have a mobile water supply you can trust.
