Günter Langergraber is a Professor and Head of the Institute of Sanitary Engineering and Water Pollution Control at the University of Natural Resources and Life Sciences, Vienna (BOKU). He also serves as Deputy Head of the Department of Landscape, Water and Infrastructure since 2025. With expertise in nature-based solutions , constructed wetlands , and resource-oriented sanitation systems , his work integrates modelling and simulation with practical applications for wastewater treatment and urban sustainability. Habilitation in Sanitary Engineering (2012), BOKU PhD in Natural Sciences (2001), BOKU His research focuses on developing advanced wastewater treatment technologies using constructed wetlands , biochar systems , and smart sensors . Key areas include urban water circularity , stormwater management , and climate resilience through nature-based infrastructure . He leads major EU-funded projects like ProCleanLakes and UniNEtZ , emphasizing the role of sustainable sanitation in achieving SDG 6 . Recent publications analyze: Design optimization of vertical flow wetlands using numerical models Implementation frameworks for circular cities via nature-based solutions Hydrological dynamics in Mediterranean and tropical wetland systems Soil water balance quantification via stable isotopes Scientific accolades include IWA Fellow (2014) and the IWA Project Innovation Award (2011) . He has supervised 478 publications and 56 projects, including EU Horizon 2020 initiatives and Austrian Science Fund (FWF) programs. As a keynote speaker at international conferences, he advocates for renaturalized urban water systems and decentralized sanitation . Langergraber contributes to technical guidelines (e.g., DWA-A 272) and policy reports for Austrian ministries. His work bridges academic research , industry collaboration , and public engagement through media appearances and training programs for wastewater plant operators.
