Geberit Pluvia® siphonic roof drainage system

Geberit Pluvia®
siphonic roof drainage system
What is Geberit Pluvia®?
Geberit Pluvia® is a roof drainage system based on an intelligent negative pressure
suction system. In contrast to conventional drainage systems, Geberit Pluvia®
offers solutions for the architecture of today. The high-performance Geberit Pluvia®
roof outlets are linked together directly under the roof with a non-sloping collector
pipe. Large roof areas can thus be drained through a single discharge stack. This
simplifies planning and reduces construction time. Cost-intensive discharge
stacks and drains are dispensed with, multiplying both the planning options
available to the architect and the potential uses for the building.
The Geberit Pluvia® was named as the 2009 Rainwater Harvesting
Product of the year at the 2009 Master Plumbers and Gasfitters
Association of WA Awards for excellence.
Geberit Pluvia® – The System
Based on the vacuum principle, the Geberit Pluvia® siphonic roof drainage system
offers incredible performance. The innovative roof drainage system can discharge up
to 100L/s of rainwater per outlet.

How does Geberit Pluvia® function?
Geberit Pluvia® negative pressure suction system:
fast, clean and inexpensive
Unlike conventional roof drainage methods, the Geberit Pluvia®
roof drainage system functions as a siphonic system, as shown in
simplified form in Illustration 1. The pipeline system fills up as
rapidly as possible, due to the correct pipeline dimensioning and
arrangement of the Geberit Pluvia® roof outlets, thus generating a
negative pressure in the pipeline. This negative pressure in the
pipe rapidly discharges the rainwater (Ill. 2), instead of merely
allowing it to drain away using gravity, and also ensures an
improved self-cleaning function.

Proplanner is convenient to operate, easy to learn and
The Geberit HDPE range of pipes and fittings is the ideal system to
meet the requirements of the Pluvia® roof drainage system. Due to
its outstanding material characteristics Geberit HDPE is especially
suitable for prefabrication.
The Geberit Pluvia® fastening system was developed for the
installation of exposed horizontal roof drainage piping. The expansion
and contraction of the pipes that occur after installation are absorbed
by the system itself. For this purpose, all mechanical forces are
transmitted to the square steel rail routed parallel to the pipe.

■
Large spans between beams can be bridged in bay structures.
■
Fewer fasteners to building structure
