About 170 employees from water suppliers, companies and authorities in the water sector met on 14 May 2019 for the 28th Dresden Drinking Water Colloquium. As in previous years, TZW had put together a topical, diverse programme of talks for the event in Dresden’s town hall. Experts presented the results of ongoing and completed research projects, practical projects and responded to current issues on water quality, water treatment and water distribution. “Microplastics in water”, “Significance of geogenic impurities for drinking water supply”, “UV LED technology in drinking water disinfection” or “Enterococci findings in drinking water” were just some of the topics. Participants also used the opportunity for expert and personal discussions.
