New roofing materials and modern building technology has given consultants more freedom to design larger and more complex roof areas and impose greater demands on the roof drainage system. Furthermore contractors are relentlessly searching for more and more cost effective ways of meeting specification whilst simulatneously reducing time in the construction program.

Substantial benefits can be gained when using AQUATECH SYPHONIC roof drainage:

• Reduction in the number of downpipes required.
• Elimination of underground drainage and associated groundworks.
• Elimination of underfloor drainage.
• Reduce water buiild up on the roof surface, thus minimising the risk of ingress in to the building and potential maintenance problems.
• For ultimate integrity, roof outlets can be prefabricated into gutters and flat rooves without bolting.
• Very long buildings can be drained with discharge points only at the end of the building.
• Use of smaller pipe sizes, typically half the diameter of the equivalent gravity drainage systems.
• Less space taken up. Collector pipes are installed horiontally requiring no fall.
• Time savings can be achieved in the construction program.
• The system is self-cleansing even in storms below the design value.
