The many benefits of roof drainage with negative pressure

The right technology ensures a better result: While conventional systems simply allow rain to run off through sloping pipes, the compact Geberit Pluvia pipe system fills up quickly and extracts the rainwater from the roof using the resultant negative pressure. The Geberit Pluvia roof outlets prevent air from being sucked in and guarantee reliable performance. The result: double the amount of rainwater discharge at half the pipe diameter. There is also greater design freedom in terms of planning, since there is no longer any need for pipelines that have to be laid with a slope.

Conventional roof drainage system Geberit Pluvia siphonic roof drainage

• High savings in materials

• Fast installation

• Architectural flexibility of design due to optimal use of space

• High flow capacity results in efficient self-cleaning effect

• High performance and reliability

• Possible to pre-install the pipe system on the floor

FEWER ROOF OUTLETS

Thanks to the high discharge rate of the siphonic system, fewer roof outlets are required. This results in savings in product material and the amount of work needed, while also preserving the roof.

FEWER DISCHARGE STACKS

Because the pipes are filled completely, fewer drains are required. The result: greater flexibility in planning.

FEWER UNDERGROUND PIPE CONNECTIONS

Fewer discharge stacks and fewer connections mean lower installation and material costs.

SMALLER PIPE DIAMETER

Geberit Pluvia pipelines are designed for complete filling. This reduces the pipe diameter to the bare necessity.

SELF-CLEANING SYSTEM

The high flow velocity of more than 0.5 m/s when the pipeline is filled produces suction which contributes to the self-cleaning of the system. This ultimately means less time spent on maintenance.

NO SLOPE

Because Geberit Pluvia pipelines are laid horizontally, the drainage system does not result in any loss of space.

All-round reliability

Suitable for all types of roofs

One system from the roof to the underground pipe connection: Perfectly matched components ensure that the overall system functions flawlessly. Sophisticated details and a consistently high level of material quality reliably ensure durability, safety and smooth operation.

Siphonic roof drainage for all scenarios: Thanks to the modular construction and the many models of the Geberit Pluvia roof outlet, the system is suitable for almost all installation situations on large buildings and roofs. Required accessories for virtually all applications are available, and can make the system highly flexible. Whenever complex roof structures or difficult geometries pose a particular challenge, the Geberit team would be happy to work with you to find a solution.
