ONE evening in Spain in 2006, global water experts Asit Biswas (AB) and Cecilia Tortajada (CT) sent a last-gasp email message to Mr Khoo Teng Chye, chief executive of Singapore’s national water authority PUB.
Professor Biswas, 71, and Dr Tortajada, 48, are husband and wife, and they were then preparing to contribute to the Human Development Report on the world’s best water management systems, including those in Britain and the United States when, six weeks before their deadline, someone said they should study Singapore’s water systems. So they shot off a note to Mr Khoo, even as a friend who used to work in Singapore warned them that it would take ages to get such data from the Government.
However, Prof Biswas recalls, ‘Lo and behold, when we woke up the next morning, we received an e-mail from Mr Khoo saying, ‘What do you need?
Whatever you need is at your disposal.” So the Biswases not only got to report Singapore as an epitome of water management, but are now also completing a book titled The Singapore Water Story, which they hope to launch here next year.
Working with PUB impressed them so, they nominated it for the Stockholm Water Prize in 2007, the Oscars for the industry, and PUB toasted its eventual win in Sweden with Newater, the reclaimed water produced by PUB.
Prof Biswas, himself a Stockholm Water Prize winner in 2006, is the founder-president of the Third World Centre for Water Management in Mexico, of which his Mexican wife is deputy president. Between them to date, they have advised more than 20 governments on national and international water policies and best practices, including recommending that the National University of Singapore (NUS) set up the Institute of Water Policy. They met when Prof Biswas was at the World Bank and advising the National Water Commission of Mexico, where Dr Tortajada worked.
Prof Biswas is currently a Distinguished Visiting Professor at NUS’ Lee Kuan Yew School of Public Policy, while his wife is a visiting don at the same school. They sat down with me earlier this month to discuss the recent floods here.
AB: One of the facts of life anywhere in the world is that you cannot eliminate floods completely, technically or otherwise. You can only manage them, and control them – to a certain extent. I try to tell my students at Oxford University that no society has unlimited money to do so.
CT: But the Government’s response to the floods here was fast, which you don’t have in many other places. And it’s good that the people of Singapore question the Government because then it improves. Many people in other cities say, ‘We’ll live with this’, and as a result their governments tend not to bear responsibility. But again, you can have big barriers in Orchard Road, but if you have higher precipitation than that, there is nothing you can do because the infrastructure is designed to keep out a certain amount of water at a time.
AB: If you look at the way some of the shopping malls in Orchard Road are designed, any time the floodwaters go over street level, all the water can go only into the basements. That design is not the best. What you have to do is provide some sort of buffer or walls for malls so the water is kept on the street and does not flow down to mall basements. That will not need an enormous amount of money.
CT: What’s happening now is that people are wealthier and their shops have more expensive goods. So their losses are higher, not because of unusual floods but because they have much more goods, which are much more expensive.
AB: And with urbanisation, everything is made of concrete so the floodwaters also have difficulty percolating. So these are some of the things which need to be explained to the people so they realise that there is nothing wrong with floods, but we have to be prepared to manage them.
AB: I cannot tell you with a straight face that the weather has changed. But as a scientist, I can confirm that the weather is changing slowly, although we have no evidence. The weather throughout history has always fluctuated.
