Siphonic Roof Drainage is an innovative technique allowing the effective removal of large volumes of rainwater using the minimum of pipework. Developed in Scandinavia during the late 1960’s, significant development and improvements in the design of siphonic systems have taken place with particular reference to construction methods in the UK and Ireland and offers a typical cost saving of 20% to 25% over conventional gravity drainage.
Implementing a siphonic roof drainage system requires the consideration of numerous factors to gain maximum benefit and ensure the roof drainage system will cope with the heaviest of rainstorms.
