In September 2016 we had the opportunity to welcome more than 70 young PhD students from German speaking institutes from Germany, Austria, Luxemburg and Switzerland working in the field of urban water systems engineering. The topic of this year’s annual meeting at the TU Munich was “Engineering under Climate Change Impacts & Water Reuse”. Within the scope of the conference program, the keynote speakers Prof. Dr.-Ing. Peter Cornel und PD Dr. Thomas Kluge provided a basis for interesting discussions and information exchange. Additional workshops and an excursion to the drinking water abstraction Mangfalltal (Stadtwerke München) ensured a diverse program. This 37th so-called “Assistententreffen” offered participating PhD students a great platform for networking and exchange of experiences. We are looking forward to the next “Assistententreffen 2017” in Kaiserslautern.
