Introducing the TZW test centre
What does the TZW test centre do?
A three-minute video shows what is done there to protect drinking water quality. Every material that comes into contact with drinking water must be thoroughly tested in Germany. Migration and microbiological testing, odour testing, mechanical testing and UV testing are just some of the many tests on the work schedule at the old waterworks in Karlsruhe. The video offers exciting insights behind the scenes of the TZW test centre.

A quicker way to track down enterococci
The video offers insights into the work of the microbiologists at TZW.
It focuses on a research project entitled “Enterococci in drinking water systems”. In the DVGW-funded project, scientists at TZW used a new method to identify enterococci quicker using the MALDI-TOF spectrometer in order to identify possible contamination causes.
