RoCube — The multi-purpose horizontal underground tank.

Maximum storage volume with minimum excavation.

The RoCube is a horizontal underground tank made from high-density HDPE. Its flat shape offers the most volume with the least excavation depth. Available in 4 capacities — 5.000, 7.500, 10.000 and 15.000 litres — for rainwater harvesting, drinking water supply, industrial use and fire reserves.

Why the RoCube?

With the RoCube range of flat tanks, we set new standards in water management. As heavy rainfall events, droughts and water scarcity increase, using rainwater efficiently matters more and more — and the RoCube is the ideal solution. With capacities of 5.000, 7.500, 10.000 and 15.000 litres, these tanks offer maximum flexibility.

Thanks to the shallow installation depth and the lower transport costs, you save time and money. The tanks fit the ground perfectly. Connect several RoCubes to build a large-volume storage system.
