• Keep drinking water safe with food-grade MDPE construction

Whether you're converting a camper van or need on-board water for mobile work, this 31-litre camper van water tank provides a compact, tough, and hygienic solution. Made from food-grade MDPE, it's suitable for storing drinking water, washing water or greywater — all safely tucked inside your vehicle.

With a low-profile rectangular design, it’s ideal for installing under seats, alongside panels, or in storage bays. The ½" BSP female outlet makes it compatible with most 12V pump setups or tap systems, while the rigid body resists knocks and bumps during transit.

Popular with DIY van builders, mobile valeters and event caterers, this tank strikes a balance between size and simplicity — no excessive bulk, no plumbing headaches. For added flexibility, pair it with our camper van fitting kit (sold separately) to secure it in place and connect pipework easily.

Available in both natural translucent and black. Not sure which colour to choose? Natural translucent tanks will let you see a visible water line in the tank, so you can check capacity at a glance — but if left in direct sunlight without agitation, the UV rays can develop bacteria and algae in the tank. Black tanks may be opaque, but this is their advantage: they are UV-resistant and the safer option when stored in direct sunlight.

Please note: while the plastic is food-grade, the tank itself is not WRAS approved for mains water systems.
