Siphon rainwater drainage and advantages with larger buildings

Siphonic rainwater drainage system is relatively new idea in the construction industry. Originated in Finland, and in the past half a century has been globalised. It’s becoming increasing common choice with architects due to its effectiveness in large commercial and industrial buildings. In contrast with the conventional system, this approach aims to prevent air ingress into the pipe network and induce a full bore flow condition. This is achieved by utilising natural forces, such as negative pressure and gravity, to rapidly and efficiently remove the high volumes of water from the roof. System consist of air controlled roof outlets, HDPE pipe network & fittings – coordinated via a sophisticated designed programmes. Siphonic rainwater drainage system negates the need for a slope in the pipework and reduces significantly quantities, thus saves space within the structure, programme time and costs. It is a reliable method of safeguarding the integrity of the buildings.
