Gravity flow Full bore flow

1/3 water water
Gravity flow vs. Full bore flow
Conceptually, if air can be removed,
you need only 1/3 of the conventional pipe size
to drain the same amount of water….
Full Bore Flow
Siphonic action can be observed when we drain water from a fish tank. A pipe or hose filled with water is used, with one end dipped into the water in the tank, and the other end discharging at a lower level.

Advantages of Siphonic System
In Building
Full Bore Flow
Gravity Flow
Deeper water above outlet
Less waterdepth above outlet
Bigger pipe size
Smaller pipe size
Pipe with gradient
Pipe run level without gradient
Clashes with other services
Easy co-ordination with other services
• Reduce pipe dimension by 1/2 to 2/3 of conventional system

SIPHONIC TACK IN SERVICES’S SHAFT
1) Provide total freedom & flexibility in roof drainage design for both the architects & engineer alike.
2) Change & revolutionize the perception of roof drainage design from merely a need of solving problem, to a total roof drainage management solution.
3) Integrates the hydraulics, structural & architectural aesthetic requirements into a complete design solution.
4) Improve buildability of buildings & roof drainage system.
Conclusion
• Fast Flow System siphonic technology has managed to:
