Graf Rondus rainwater storage tank 2000 litres for shallow ground applications is ready to ship and IN STOCK. This is the revolutionary Rondus underground rainwater storage tank introduced to allow underground tank storage in areas where only a shallow excavation is possible.

Use the Rondus for rainwater harvesting in the house and garden

Ideal for difficult installation situations, e.g. rocky subsurface

Ground-water-stable. The Rondus underground tank is, due to its specifically engineered design, so stable that can be completely installed in ground water and stratum water, as well as cohesive ground surfaces (i.e.,  loam – in connection with buoyancy control). The maximum ground-water level corresponds to the upper edge of the land. 

Flat design The flat design of the Rondus enables a sensationally shallow mounting depth - which means a less excavation than for a classic rainwater-based system – in fact, excavation is reduced by approx. 40%. Even so, all components which carry water are at least 60 cm below ground – in the frost-free level.

Total Height 1280mm, Length 2190mm, Width 2010mm

The Rondus tank comes with a Pedestrian PE Lid (green) and seal kit. To order a Vehicle loading lid GF-381504 or an extension to the turret Gf-319501 please call 01733 405100.
