WE ARE A SPECIALIST SUPPLIER
OF SIPHONIC ROOF DRAINAGE SYSTEM
What is JAS Siphonic?
JAS Siphonic is a rainwater drainage system that utilizes siphonic principles and fluid mechanics. To enable a continuous full-blow flow of drainage, the Siphonic system requires smaller pipes than the conventional drainage system, which can drain 10 times faster and also, is flexible in design. The pipework is calculated to maintain velocity and negative pressure to ensure the efficiency and safety of the drainage system.
The JAS Siphonic is designed by specialist engineers of the siphonic water management system according to BS EN 12056-3: 2000, BS 8490-2007.
Why JAS Siphonic ?
Flexible pipe routing
Smaller pipes due
to full-bore flow
Less pipes required due
to faster drainage
Less manholes and underground pipework
No slope required for horizontal pipes, providing extra space
Smaller rainwater gutter
HDPE pipes are highly resistant to negative pressure, no risk of pipe damaging from pressure
Reduced project cost up
to 55% – 65%
