TZW has its main site in Karlsruhe-Hagsfeld. In addition to the modern office and conference rooms, this site contains the laboratories of the specialist departments of water analysis, micro and molecular biology, water chemistry research and the groundwater and soil department. The technical facilities and test set-ups for the departments are also given the space they deserve. However, most pilot plants are operated directly on site at our customers.
The corrosion department and the Test centre are based in Karlsruhe in the Durlacher Wald waterworks of Stadtwerke Karlsruhe. This is also where the Heinrich Sontheimer laboratory is located, which was set up in cooperation with the municipal utility companies and shows the close collaboration between TZW and the Stadtwerke Karlsruhe.
The Dresden site is located within the Hosterwitz waterworks of DREWAG Stadtwerke Dresden GmbH. The specialist areas are focused on water distribution in addition to providing regional consultation to water supply companies.
