Welcome

 

Siphonic drainage was first introduced in the 1960ís in Scandinavia and since then has been used widely across Europe, including the UK, in the Far East, Australasia, South Africa and the USA.. Many large industrial, commercial and retail buildings are now fitted with siphonic drainage, which has clear advantages over gravity drainage .

 

 

     
   
     
 

Only one or two downpipes are needed per gutter, freeing internal space.

Reduces underground drainage, saving on cost and programme time.

Eliminates the need for almost all under slab drainage.

Uses a fully sealed, leak free pipe system.


The Siphonic Roof Drainage Association is set to provide a recognised platform for specifiers. Members have to show that they use an outlet, pipe system and design software which has been assessed as suitable by a third party organisation. They are also subjected to an annual random check by the Association to confirm that their design and installation procedures are being properly implemented.

By using a member of the SRDA, a specifier can ensure that they are going to a company which has the tools and experience to do the job properly.
