Abstract

On behalf of the International Water Association (IWA) and its Specialist Group on Design, Operation and Costs of Large Wastewater Treatment Plants and the Institute for Water Quality and Resource Management at TU Wien, it is our pleasure to invite you to join us for the IWA Specialised Conference “Design, Operation and Economics of Large Wastewater Treatment Plants”. This conference is the 13th in a series of conferences and celebrates in 2020 the 50 years anniversary of this great event. The first conference of the specialist group was held in Vienna and the anniversary conference will come back to this venue during a perfect time of the year – not only with respect the expected weather in Vienna but also because of the finalisation of the upgrade of one of Europe-s largest wastewater treatment plants, the Vienna main wastewater treatment plant.
