WSD joined the Science in Public Service Fun Fair held on 14-16 November 2008 at the Victoria Park by providing two booths: one on the advanced technologies for replacement and rehabilitation of water mains and the other on leakage detection technology. We also displayed the award-winning solar car in the Hong Kong Technology & Renewable Energy Event. The fair aims at letting people know, in a light-hearted manner, more about the Government's application of science and advanced technologies in providing services. More than 30 government bureaus / departments, collaborating organisations and tertiary education institutions took part in the event.
