WHY CHOOSE A SYPHONIC SYSTEM ?

  Syphonic roof drainage systems have been in use in the UK since the early 1990s.

 
For more information on Syphonic Systems here are two excellent PDF articles by Geberit Technical Team.

Conventional Systems Versus
Syphonic Systems


Fall 1 - 3% No fall necessary
Many down pipes Fewer down pipes
Long underground pipes Short underground pipes
 
Large pipe dimension Smaller pipe dimension
 
Higher maintenance
costs
Syphonic systems are self-cleansing because of the high flow rates, thereby minimising maintenance costs
 
Design flexibilty
limited
Downpipes are generally located inside buildings which provides visual enhancement in the majority of situations
   
   
 
    Demands from architects and contractors on modern buildings can often make the installation of conventional rainwater drainage a difficult task.

     
    Several factors have to be considered to make syphonic rainwater system work effectively. Specially designed roof outlets take into account rainfall intensity rate and to design the pipework configuration to optimise performance.

     
    Rainwater removal from roofs has to be quick with a high level of safety. Occasional high rainfall rate over a short
time has to be considered with the design of an overflow system to cope with the high demand.


     
    Rainwater can be easily routed to collection tanks for future recycling, e.g. irrigation, fire ponds, sanitation etc.

     
    Syphonic outlets are designed to reduce the entry of air into the system and stops vortices forming that will draw more air into the system rapidly. Pipes are designed to run 100% full of water at high velocity from roof level to ground level, vastly increasing the capacity of the system when compared to traditional methods of roof drainage.

     
    Acceleration of construction programme due to reduced installation period.

     
    Software packages save time and provide: Isometic drawings, Hydraulic calculations, Material lists including fixing components. All documents are available in hard copy or can be emailed anywhere in the world.
