Convention Centre "Darmstadtium"

The extraordinary architecture of this congress centre demanded high standards with regard to design and construction of sanitary installation. In the underground parking, where the technical rooms are, it was not possible to lay pipelines in the passage area. The toilets and wet rooms, especially destined for the concert hall, are spread and arranged irregularly in the entire building. It should be easy to carry out any future conversions or enlargements.

Challenge

Furthermore, a special water saving technology as well as a separation of the sewage water flows were planned. Additionally, for the different rent units of the catering area and the restaurant, the grease containing sewage quantities were to be discharged and led into the de-central grease separators.

Solution

Through the use of vacuum technology and the associated very flexible pipeline installation the discharge of the individually arranged toilet- and bathrooms was quite easily practicable. By conducting the pipelines at each floor inside the suspended ceiling area, a laying of the pipelines in the underground parking area could be excluded. Likewise, a later conversion of the rent unit for a restaurant could be easily realized.

Key Features

By the use of the new Roediger® Silentium vacuum toilets the water consumption is reduced to only 1 liter per flush. Urine containing sewage will be collected separately.
