By removing the need for vent pipes in drainage management, the hydraulic SuperTube allows architects to maximise floorplates in taller buildings - and profits potentially too
New to the UK market, the Geberit SuperTube system combines the existing 12 litres per second flow-optimised HDPE Geberit Sovent (d110) with two new bends, the BottomTurn and BackFlip. These remove the need for a vent pipe by generating a constant air stream through intelligent design.
Enabling pipework with a smaller, consistent diameter of d110, the combined single stack system offers potential space savings of up to 20% in the duct and 40% in the ceiling void, maximising space available.
With a maximum discharge capacity of 12 litres per second, Geberit SuperTube also offers horizontal pipelines of up to 6m without slopes, thanks to the design of the BottomTurn bend which reduces impulse losses during transition from the vertical to horizontal. All this with simple planning and quick installation too.
In one successful installation in Egypt, contractors calculated more than £1 million (€1.1 million) in extra potential sales revenue, made possible by reducing the space needed behind the wall to maximise the floor and living space over 23 floors.
In this example, SuperTube used around 50% of the space originally allocated for a triple stack system in a prestigious development comprising a large residential tower and hotel. While this particular system is not common in the UK, significant space and cost savings are still achievable by removing the need for a vent pipe.
Greg Austin, assistant product manager for drainage at Geberit, said: 'Figures from New London Architecture (NLA) show that there are 541 tall buildings (over 20 storeys) planned in the capital and 90% of those are residential, delivering an estimated 110,000 new homes in London alone. It is vital therefore that architects and specifiers are selecting the right solutions to maximise the potential of these buildings, both for developers and for their purchasers.
'The rapid evolution of flow-optimised single stack drainage systems for wastewater in high-rise buildings has meant there are no UK standards specifically applicable to support architects and specifiers in their specification design choices. It’s down to manufacturers like Geberit, as specialists in drainage technology, to put forward innovative solutions with clear and demonstrable benefits.
'Geberit SuperTube is a space-gaining system which is single-handedly driving the evolution of optimised hydraulic draining systems by unlocking valuable building space to save time and money.
'Parallel ventilation pipe is no longer required, creating more residential and floor space, while pipelines with consistently smaller dimensions allow smaller pipe ducts to be used. This creates potential for significant cost and time savings when compared to alternative systems.'
