LET2020 – The 17th IWA Leading Edge Conference on Water and Wastewater Technologies

The IWA Leading Edge Conference on Water and Wastewater Technologies is designed to be the place where new ideas are introduced and the opportunity is provided to interact with the “best of the best”. This is the global conference where new insights into how pioneering science, technological innovation and leading practices shape the major transformation in water management that is underway. The LET conference is held in a different country every year. After unparalleled success in Amsterdam (2003), Singapore (2007 & 2009), Zurich (2008), Phoenix (2010), Amsterdam (2011), Brisbane (2012), Bordeaux (2013), Abu Dhabi (2014),Hong Kong (2015), Jerez de la Frontera (2016), Florianópolis (2017), Nanjing (2018) and Edinburgh (2019), IWA is hosting its 17th Leading Edge Conference on Water and Wastewater Technologies in 2020 in Reno, USA, which complements the approaches of urban water management between megacities, smaller towns and rural environments, driven by the diversity of climatic conditions and the natural and human environment.
