Pluvia roof outlet

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 collec-

tor 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 avail-

able to the architect and the potential uses for the building.

What is Pluvia?

limited structural design options

Whether it be 1000 m2 or

100,000 m2 – Geberit Pluvia is

always the suitable system

The technical principle and the high

drainage rate of Geberit Pluvia ensure

that the system can be used in a wide

range of applications. Installation is

possible in both cold and warm roofs.

Inverted roofs and different kinds of

greened roof surfaces – whether ex-

tensively or intensively greened – can

be drained with Geberit Pluvia.

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.

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 advantages of Geberit Pluvia

The Geberit consultants have received optimum training in

the Pluvia System and also offer world-wide support for the

planning and design of Pluvia installations.

Geberit ProPlanner (Pluvia Module):

Take advantage of Geberit's many years experience in the

field of negative-pressure roof drainage.

The Geberit ProPlanner Pluvia Module supports planners

in the designing of optimum negative pressure systems.

Utilising Geberit's extensive experience in rainwater drainage,

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
