13 September, we had the next interesting excursion to Waterworks Tolkewitz, which was built about one hundred years ago. It is placed on the left bank of the Elbe River and uses the river water as a source for producing drinking water. At the plant we were welcomed by the former head of the Water works Tolkewitz, a very kind and experienced man. During the following hour he explained the formation and development of the drinking water supply system of Dresden. After that, we visited the drinking water treatment area. The pipe system is completely isolated from the external environment to make sure that the water will always meet all standards and norms. It was a system worth learning. Finally, I would like to thank Dr. André Lindner for his translation work during the whole excursion.
