A high-capacity 100L wheel arch water tank designed to maximise water storage while making efficient use of the space around a campervan or motorhome wheel arch.
 
Manufactured from durable, rotationally moulded MDPE, with a seamless construction designed for long-term mobile use. The semi-transparent tank body also allows the water level to be visually checked more easily.
 
Supplied with a dedicated mounting kit included for secure installation.

WHEEL ARCH DESIGN
The shaped profile allows the tank to fit over and around the vehicle wheel arch, turning otherwise awkward space into substantial onboard water storage.
 
Despite providing 100 litres of capacity, the tank is only 26 cm deep, making it particularly useful for campervan layouts where preserving usable interior width and storage space is important.
 
SEMI-TRANSPARENT DESIGN
The natural semi-transparent MDPE construction allows the approximate water level inside the tank to be seen without requiring a separate level gauge.
 
This makes checking the remaining fresh-water supply quick and straightforward.
 
MOUNTING KIT INCLUDED
The tank is supplied with a dedicated metal mounting kit, designed to work with the tank's integrated 8 × M8 threaded mounting inserts.
 
This provides suitable fixing points for securely restraining the tank within a campervan or motorhome installation.
 
OUTLET & VENT
The tank is supplied with a 1/2" BSP brass threaded outlet, which is drilled/open and ready for connection to a compatible fitting.
 
The 12 cm screw lid is non-vented. Where required, a separate tank vent can be incorporated into the water system.
 
SUITABILITY
Suitable for fresh drinking water systems and manufactured from food-safe material. The tank can also be used for wastewater and other compatible liquids where appropriate.
 
The MDPE construction is UV and chemical resistant and designed to withstand the demands of mobile installations.
 
WRAS certification is available for the natural material configuration.
 
INSTALLATION
The tank should be securely installed using the supplied mounting kit and integrated M8 mounting points.
 
A full 100L tank contains approximately 100 kg of water, in addition to the tank's own 15.5 kg weight. The supporting structure and vehicle attachment points must therefore be capable
of safely restraining the fully loaded tank during vehicle movement.
 
Always ensure the tank is adequately supported and securely restrained before use in a moving vehicle.
