Suction off rain instead of letting it run off

Geberit Pluvia

Double the amount of rainwater discharge at half the pipe diameter
Geberit has been setting standards for roof drainage for decades with the Geberit Pluvia syphonic roof drainage system. Unlike conventional roof drainage methods, the Geberit Pluvia roof drainage system functions as a syphonic system. 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, instead of merely allowing it to drain away, and also ensures an improved self-cleaning function.

More freedom of design, more economic efficiency
Geberit Pluvia gives architects more design freedom, as plumbers and sanitary engineers require a smaller number of roof outlets, discharge stacks and underground pipes. Because of the negative pressure, no slopes need to be planned for the feed pipes leading to the discharge stack, which means that the installation is simpler and requires less space. The material costs and outlays for ground work are also reduced.

The Geberit ProPlanner software with the Pluvia module is appropriate for the planning. Geberit also offers the calculation of Geberit Pluvia roof drainage systems as a service.
