Got Questions?

What is Siphonic Roof Drainage? +
Siphonic Roof Drainage uses siphon action to rapidly drain roof areas without slope, using minimal pipe diameters and fewer downpipes — offering maximum efficiency and architectural flexibility.
How does it differ from gravity systems? +
Siphonic systems create a vacuum in the pipe network — enabling faster water removal, horizontal pipe routing without slope, and significantly fewer downpipes, especially effective over long horizontal distances.
What roof types are suitable? +
Flat roofs, curved roofs, airport terminals, warehouses, industrial buildings, commercial developments, and large-span structures. Its adaptability makes it ideal across a wide range of architectural designs.
What are the main advantages? +
Efficient water removal, space optimisation, cost-effectiveness, reduced material use, lower CO₂ footprint, architectural freedom, and minimal maintenance. Particularly advantageous for large roof areas.
How does Siphonic Innovations ensure success? +
5+ years of hydraulic engineering experience with DrainSmart® software, BIM integration, OEM-neutral product selection, and close client collaboration — from concept through to post-handover maintenance.
Is siphonic drainage eco-friendly? +
Yes. Fewer pipes, fewer downpipes, less material — directly reducing the carbon footprint. Easily integrated with rainwater harvesting systems for sustainable building goals.
Small Model. Big Impact.
