Our team

Our Departments of Water Supply, Water Microbiology, Water Chemistry, Water Distribution and the Test Centre are staffed by experts with comprehensive know-how in all areas of the entire water cycle. The Departments are subdivided into Units. The Finance, Human Resources and Infrastructure Department as well as the Staff Positions assume cross-sectional tasks for the TZW. Here you will find some of our 200 staff members and their special topics. To do this, unfold the individual tabs of the accordion.
