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.

Principle of Siphonic

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:
