 Today is World Water Day 2019 and the theme is Leave No One Behind. SDG6 tries to ensure safe and sustainable water supplies and sanitation services for everyone. It implies that we leave no one behind. But the reality is that there are still billions of people that don't have access to safe water supplies and who are without sanitation. And IWA and its membership have a very important role in developing solutions to address these challenges and to ensure that we accelerate the diffusion of these solutions so that they are implemented into practice. When you look more carefully at the numbers, the billions of people that don't have access to water and sanitation, many of these people are coming from marginalised groups. These include women, children, refugees, the disabled. And it's really important for our members when they conceive ideas, when they develop solutions and when they think about how to implement these solutions, that they recognise that they have to ensure that these solutions are addressing the needs of these marginalised groups. As an association, we have to encourage the water sector to transition to a more modern way of thinking around water. We have to adopt more circular economy approaches where we rethink the way in which we use water, the way in which we reuse water. We try and extract value from our waste streams and that value enables us to sustain our water supply and sanitation operations. IWA is instrumental in delivering the transformation agenda that the water sector so desperately needs. And we do this through the activities of our specialist groups that generate all this knowledge and ideas that solve these problems. And the way in which we articulate these solutions through our publications and through our conferences. And of course, we're a huge network and our members have the opportunity to get together, to share ideas and from that sharing create very innovative solutions that are going to address these huge challenges. IWA is committed to ensuring that no one is left behind.
