What is 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.

How does 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 syphonic system,
as shown in simplified form in Illustration 1. The pipeline system fills up completely as rapidly as possible, thanks 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 withdraws the rainwater by suction (Ill. 2), instead of merely allowing it to drain away,
and also ensures an improved self-cleaning function.

The advantages of Geberit Pluvia
Less planning effort, fewer discharge stacks and roof outlets
Geberit Pluvia simplifies building planning and permits optimum space utilisation.
A diminished need for discharge stacks reduces outlay for underground drain
connections and surface lines as well as the costs for the property developer.
A Geberit Pluvia installation is less expensive than a conventional roof drainage
system.
Double the amount of rainwater discharge at half the pipe diameter
The Geberit Pluvia roof drainage system has been setting new standards for
decades and demonstrates its performance capability in important flat-roof
constructions at many prominent industrial companies. Geberit's more than
30 years of experience guarantees the building operator high reliability and

outstanding durability. Geberit Pluvia reduces discharge stacks and roof outlets,
thus providing the architect with considerably greater flexibility in the planning
of the building, in the utilisation of space and in the co-ordination of different
building trade requirements.
The corresponding Geberit HDPE drainage system
Geberit Pluvia and Geberit HDPE complement one another seamlessly to
produce a complete roof drainage system. In view of the fact that high levels of
negative pressures can arise in connection with the use of the negative pressure
drainage system on large roof surfaces, the connection between the individual
components takes on special significance. The possibility of leakage can be
virtually ruled out, thanks to the lengthways non-positive connection that arises
from the welding of the shaped parts with the pipes.

the Pluvia Module automatically calculates the dimensions
of the negative pressure system, the distribution of the
roof outlets, the precise fastening points and a dimension
export with all of the required components. This means
that the planner obtains an extremely reliable calculation of
the roof drainage, which translates into planning security
and the optimisation of costs for the entire system. The
calculation integrated in the Pluvia Module always works in
accordance with the principle of economic efficiency. The
ProPlanner Pluvia Module offers the planner the possibility
of viewing the installation in an isometric presentation, which
provides an opportunity for taking better account of specific
building characteristics.
Over 70,000 projects have been carried out during more
than 30 years of experience in everyday practice, during
the course of which more than 120,000,000 square
metres of roof surface have been fitted with more than
750,000 Pluvia outlets.

Geberit Pluvia – extracting
water from flat roofs instead
of leaving them to drain
■ Hydraulically calculated: negative pressure extraction of the rainwater
(with Geberit Pluvia roof outlets)
■ Small pipe diameter, large self-cleaning effect, maximum flow capacity
■ Cost-cutting, due to fewer stacks, fewer drains and fewer channel
connections
■ Also suitable for lightweight roofs and the most diverse warm,
cold and inverted roofs
■ Possible to preinstall the pipe system on the floor
■ Routing without slope
■ Patented fastening system: efficient installation of individual system
sections
■ Minimum number of fastening points
■ Top speed: Geberit HDPE branch discharge pipes can be easily
connected to the Geberit Pluvia roof outlets using Geberit
PluviaConnect
■ Top safety: completely welded system, from the roof outlet to the drain
■ Low system weight
■ Planning service: calculation isometry, wiring diagram,
pipe dimensioning, material list, list of services
■ Planning support for pipe dimensioning
