An old water tower has been converted into the central control room for monitoring the water supply. The space in the upper part of this tower is used as a training centre that focuses on the environmentally friendly use of water resources and as a meeting room for the company management and its partners. As an aid for future training purposes, six movable television screens were set up in two rows, which move around the room in a radius of 6.8m and at an angle of 180°. In addition, there are another six movable television screens in the upper conference room, which are arranged in a single row. These television screens move in a circle with a radius of 5.9m and an angle of 45°.
