 I feel very happy to hear this news about IWA giving me a world-wide award. I think this award does not belong to me. I think this award belongs to our colleagues and all the number of WAs because in 2006 I was very happy to be chosen. I was president of the water conference. I was working for IWA and learned a lot from WAs. I think about IWA as the biggest organization for water issues. It's so successful. Helping the Diablo countries, especially like China, learn a lot of some mature technology, some lessons, some policies we can choose and we can practice, then we can learn again. I think this is a very, very good opportunity for me and a very, very good experience for me. Ladies and gentlemen, a dear chairman, I'm very glad to hear, I wanted to tell you some little stories about China urban water issues. The first story is urban water supply. Everybody knows that China urbanization gets a long, long time, maybe 30 years ago. It means each year more than 15 million farmers migrate from rural area to cities. Also means water supply will be and should be top priority issues for local government. So we put a lot of money and hard workers, but it's not very successful. In 1980s, only 40% of urban residents have been covered by the sanitation water supply. But now, more than 97% of urban residents have been covered by sanitation water. It's very successful, but we still long way to go. The second water story is saving water, because water resources in China is so limited. More and more people want to live in cities. But you know, other people getting richer and richer, they want to use more and more water. So the government and NGO encourage people how to save the water. The water saving policy and the recycling water technology are getting more and more mature now. So urban population gets more and more increased. But water consumption is stable in China. This means capital water consumption declined continually in China. The third story is a quality of water. Some philosophers said, no quality, no quantity. Water quality is very important, because most of the diseases come from the unsustainable and also the unclear water. So that's why in China sanitation water standard is getting more and more strengthened. From 35 terms to 106 terms now, China as a developing country. But our standard of drinking water is very closely to Europe and the United States. That's good news. The fourth story in China urban area is how to recycle use of water. Because in China, water resources are so unbalanced between south to north. Most of the water resources are located in south. But most of the population and the megacities located in the coastline and north of China. That's why so unbalanced of water resources and demands. So we need to get rebalanced. So in a traditional way, people always think about several canals transferred from long distance to south to north. But it means a waste of a lot of energy. Now we find another way. We call it the LID model. LID models means people build a city, a planning city to suck rainwater, to storage rainwater and recycle rainwater and to save water. And use some new technology to recycle water one time and another time. So that means water can be used no limited. It's a good beginning, but we still have a very long way to go. The good story is just the beginning. The last but not least story is how to control the water pollution. Because China is the biggest country for population and also the biggest goods manufacturing countries in the world. That means a lot of factories and a lot of companies have a lot of waste waters come from cities, come from the buildings. So water ecosystem is destroyed. That's very dangerous, not only for this generation but also for the next generation. So some cities located in coastline are randomly water, but they are getting more and more serious water shortage. This we called water pollution cost serious water shortage. That's why we put a lot of money and a very hard job to push government to build more water treatment factories against water pollution until now. The story is successful. More than 87% of the waste water treatment but 10 years ago only half waste water had been treated. That means we save a lot of ecosystem to protect the space for next generation. Another way to control water pollution is the emerging system. So we established some information system to collecting more than 1,000 chemical elements and control elements and more than 1,000 pollution cases put together. If we find some place, some pollution emergency issues happen, maybe some come from the transportation accident or some come from chemical factory explosions or some disasters. So water system be destroyed totally. In that time our information is very helpful for local government and local people. It will teach them to introduce them how to respond to them, how to deal with them as soon as possible. Ladies and gentlemen, whatever we did successful or some bad lessons, we really, really still have a long, long way to go. 10 years ago attending an IWA conference. This conference was so successful. This conference tells us a lot of mature technology and mature water policy. We learn from all the world. So today we are getting together again attending IWA conference, water conference again. So we want to see this opportunity to tell the story happened in China. I do hope we can learn from all of you to do something better than now. Thank you.
