In the main building of the GIZ headquaters located in Eschborn, 23 waterless urinals of Keramag and 38 RoeVac© NoMix toilets have been installed for the source separation of the wastewater streams.
Within this project component, the RoeVac© NoMix toilets are tested in a continuous-operation mode and necessary modifications are made.
In the course of the project several modifications of the technical components of the RoeVac© NoMix toilets were carried out. In spring 2010 the urine separation valves were modified and potential leakages could be minimised. Furthermore, the Bowden cables were optimised. To reduce the deposition of urine scale, the interior of the valve was smoothened.
This component was led by Roediger Vacuum GmbH and supported by GIZ.
