We are proud to host IWA Congress and Exhibition about: “Water for smart liveable cities”. This topic addresses the challenges of the future and we will demonstrate smart water technology, system solutions, governance and policy in order to secure resilience in future towns and cities of the world.

Welcome to Denmark and Copenhagen 11 - 15 September 2022

Denmark has a long history of water and a remarkable tradition for sustainable solutions. Copenhagen is a liveable, blue and green city introducing smart integrated water solutions. In Denmark we drink groundwater directly from the tap, and thanks to efficient waste water treatment you can swim in our harbour, and our beaches are clean. New climate resilient neighbourhoods are being planned and built. Congress delegates will have plenty of opportunities to explore this living water laboratory.

Call for content

The 2022 World Water Congress & Exhibition in Copenhagen, Denmark is designed to bring together over 10,000 water professionals from academia, utilities, industry, government, regulators and NGOs and also engage the water-consuming industries and other parallel sectors. We invite you to be an active player in shaping the future of water at the IWA World Water Congress & Exhibition 2022 by submitting your outline papers, workshop or training proposals by 31 December 2021.
Through the underlying theme ‘Water for smart liveable cities’, a concept in which Denmark is leading, we will explore smart, holistic and liveable city solutions that utilize synergies between various intelligent systems, empower cities to adapt to a changing climate and meet the Paris agenda, whilst improving the quality of life and well-being of our societies. In addition, we will contribute to developing a global culture of innovation that can enable the radical transformations required.
