Geberit Pluvia roof drainage

The power of siphonic performance

Fewer pipelines, more performance, more useable space

Geberit has been designing and perfecting siphonic roof drainage systems since the 80's. Today Geberit is a world leader, with Pluvia siphonic drainage systems having been installed in more than 30 countries. Geberit has more than two decades of experience in the Pacific region. Some of the most ground breaking architectural designs have been made possible thanks to Pluvia siphonic technology. Large roof areas can be drained using fewer pipes and simplified hydraulic designs, releasing architects from the restrictions of conventional roof drainage systems.

Maximise usable / saleable space and minimise costs without compromising quality:

  • Pipes flow full under negative pressure
  • Cost effective with fewer pipes and smaller pipe diameters
  • Space saving due to smaller pipe diameters, smaller duct sizes
  • Fewer underground pipe connections, roof outlets and downpipes result in high savings in labour and materials
  • Rainwater travels at high velocity, maximising the discharge capacity and reducing the risk of blockages
  • Greater design freedom and flexibility, maximum use of space due to horizontal pipelines without slopes

Technical support and priceless warranty provided

Geberit and Reece have been supporting plumbers, builders and designers in Australia for almost 20 years. Reliability and trustworthiness are key factors when it comes to supporting large projects. Geberit and Reece work together to provide the product, technical support and installation advice for any siphonic roof drainage project at every phase. Hundreds of projects have been successfully completed in Australia demonstrating that siphonic drainage has significant benefits over conventional roof drainage.

For long term piece of mind, Geberit will provide warranties on Pluvia projects installed to the correct specifications.

Geberit's ProPlanner software makes design of siphonic drainage systems easier. Geberit also provides BIM data for Autodesk Revit with Revit files for all components used in Geberit Pluvia siphonic drainage systems.
