Flat design

The flat design of the Rondus ensures a sensationally low installation depth and less earth therefore needs excavating. Compared with a classic rainwater tank, the amount of earth excavated is reduced by around 40 %. But if combined with the telescopic dome shaft, all parts carrying water are still in the frostfree area.

Lorry-bearing

Do you want to fit the Rondus underground tank in your courtyard entrance? When combined with the cast telescopic dome shaft, the Rondus is suitable for vehicle loading – the Rondus plus can even be lorry-bearing with an axle load of max. 8 t (if combined with the BEGU telescopic dome shaft).     

Groundwater stable

Thanks to its special design the Rondus underground tank is so stable that it can be fully fitted in groundwater, stratum water and cohesive soils (e.g. loam) (in combination with anti-buoyancy measure). The maximum ground water level corresponds to the top edge of ground.

They adjust to any and every surface:

The Rondus telescope manhole pits close the system to the upper edge of the land. For an optimum adjustment to the conditions, on-site, the height continuously adjustable, also , the unit can be tilted by 5° - they seal the entire system - with two lip seals – up to the upper edge of the land.

• Can be installed in ground water and stratum water, as well as cohesive soils (e.g.,  loam).
• In general, should be installed in a frost-free area through a tank dome 500 mm (in conjunction with telescopic dome shaft).
• Adjustable installation depth through telescopic dome shaft!
• Trouble-free assembly due to slight excavation.
• Long life, 15-year warranty
• Low tank weight means can be installed without crane
• Large access (> 600 mm) for easy inspection of the tank
• Tanks made from 100 % recyclable polyethylene
• Best water hygiene due to smooth inner tank surfaces and use of food-safe materials

Application:

• For rainwater harvesting in the house and garden
• Ideal for difficult installation situations, e.g. rocky subsurface
• Suitable for installation in groundwater, max. groundwater level corresponds to the top ground surface. Follow installation instruction
• Frost-proof installation at a depth of 1,600 mm (lower edge of container)
