Syphonic drainage specialist Fullflow and rainwater harvesting company Stormsaver have formed a sole partnership in an effort to provide a one-stop shop for their products.
Fullflow's syphonic drainage system is claimed to be ideal for harvesting ideal for harvesting rainwater because fewer downpipes are required when compared with a conventional gravity drainage system. Having fewer downpipes means savings can be made on materials and underground work.
The Fullflow syphonic system is suited to rainwater harvesting because of the flexibility it is said to offer.
Syphonic drainage by Fullflow has won the contract to design, manufacture and install syphonic drainage systems for the 150 million euro mixed use town centre development on an eight-acre site at the heart of Athlone, Ireland.
Whereas a conventional outlet is a hole set into the lowest point on the roof into which water pours, the syphonic drain incorporates an anti-vortex plate that restricts the flow of air, allowing only water to be drawn off the roof. During heavy rainfall the outlet drain fills above the anti-vortex plate, cutting off air flow into the pipe and creating a vacuum.
The system potentially allows a lower number of roof outlet drains which flow out into a lower number of downpipes.
