 The Water Development Congress is mainly on topics with our link to the human right to water and sanitation. And there is still 30% of the world population with no access to water, don't have the human right to water, and even worse for sanitation. 55% of the world population don't have that right. So for us it's very important to remind that, to work on the needs, to put people together in order to find the solution, the right solution to open their mind, to exchange, because we need to find new ways of working, otherwise we will never bring that right to the people. IWA is the reference network for professionals in the water and sanitation industry. And so far the network has done a very good job in building an industry around water supply, around wastewater management, but it's not doing so well in non-seawall sanitation. And yet 4.5 billion people don't have access to decent sanitation, and I believe this is an opportunity for the IWA members to really come together and think what are the next type of technology, the next generation of technology, what type of service model, business model, and that would actually enable a new industry to launch. Circle economy principles have an important role to play in ensuring that we are achieving sustainable sanitation and water management, especially in developing countries. And market-driven mechanisms, including business models, have an important role to play because they allow the engagement of private sector, but also allows us to leverage both public and private sector capital. My hope is that the work that we have done is integrated in different policies that are being developed, but that also offers information to private entities that are keen in investing in circular economy businesses. If you dig today 200 feet, 500 feet, and tomorrow somebody comes who have the big money, rich person, they get 600 feet, then you are born to drive. Then somebody has come, again one more rich person, that is 1000 feet, then you are born to drive. So instead of digging a new borewells, you can recharge the old one, which is dry, because rainwater is given free for us. So you can just, you can put it inside. That's important. So in India, we are implemented 1,650 borewells, 10 state in India. Rainwater harvesting is open source.
