Geberit Pluvia
Geberit Pluvia is the leading syphonic roof drainage system throughout the world. Installed in some of the most presitigious and groundbreaking buildings. Geberit Pluvia provide the specifier with freedom and flexibility in design.
The system uses the gravity induced vacuum principle to create a symphonic action. This allows the complete drainage of a roof area without the requirement for a slope and using a minimal number of outlets and down pipes, saving expensive groundworks.
Syphonics allows water to be removed quickly through the use of smaller diameter pipes and horizontal runs, without fall, allowing architects to accomodate Geberit Pluvia in more confined spaces that conventional rainwater systems. Horizontal pipe runs are taken to the side of the building and then down, eliminating the need for unsightly down pipes interrupting open plan areas or atriums.
Geberit HDPE
Geberit Pluvia is the system used by Geberit Syphonics in the supply and fit of syphonic rainwater installstions. The Geberit Pluvia roof drainage system is based on the ingenius gravity induced vacuum principle. The system consists of roof outlets, pipes and fittings which constitute a full range of universal products for syphonic drainage requirements and are all made from Geberit HDPE.
Geberit Pluvia allows the complete drainage of a roof by syphonic action without the need of a slope in the pipework, and by using smaller pipe diamters.
Advantages of Using Geberit HDPE
- All Geberit HDPE pipes, fittings and outlets meet the highest quality standards and are regularly subject to quality testing
- Geberit HDPE is impact-resistant and flexes without cracking or breaking
- Geberit HDPE can withstand extreme temperature differences
- Geberit HDPE is more abrasion resistant than metal pipes
Roof Drainage
The syphonic roof drainage system is widely used in the industrial and commercial applications such as factories, airport terminals, supermarkets and sports stadiums for all roof areas larger than 100 square metres, and buildings higher than 4 meters, including flat roofs or normal pitch roofs also including domed and arch-shaperd roofs of various curvatures.
Conventional system with:
- Sloping collection pipes
- Numerous stack lines
- Extensive groudworks
Geberit Pluvia system with:
- Horizontal collection lines
- Few stack lines
- Minimal ground work
The use of HDPE pipe means assemblies can be prefabricated using the butt welding technique and installed on site using electro-weld sleeve couplings. This reduces installation time and ensures that the best possible permanently sealed pipeline can be achieved.
The range of Geberit Pluvia outlets are capable of draining between 4.5 l/s and 25 l/s
Geberit Pluvia advantages:
- Manufacturers warranty
- Fully BBA certified
- Reduced construction period
- Few pipes and fittings
- No slope of pipe work required
- Fewer underground pipes
- Less site work
- Self-cleaning action
- Reduced pipe dimensions
- Smaller voids required for the horizontal pipe runs
- New architectural flexibility in building and use

Flexibility and freedom in design allows the creation of outstanding buildings - buildings that are a landmark and a statement of intent and achievements. Restrictions on an architects creativity are often shaped by building techniques, materials, or budget, limiting the boundaries of building construction.
Geberit Syphonics seek to alleviate at least one restrictive element through the introduction of a total solution for roof drainage, providing all architects and specifiers with complete freedom in design.
Geberit brings manufacture, design, product and installation together in a complete supply and fit pacakge, utilising advanced roof drainage technologies, to provide specifiers with an alternative to conventional gravity roof drainage.
Syphonic roof drainage provides effective drainage systems for larger roof areas using fewer outlets, narrower pipe work and minimal down pipes. The principle of syphonics reduces the amount of pipe work and down pipes considerably, de-restricting space issue and removing the need for interrutpions within large atrium or open plan areas.
