By the end of 2012, the overall length of China urban water supply pipeline reached at 481,485km of which plastic pipes accounted for 103,940km. This is equivalent to 21.6% of the network, which is an increase of 166% compared to 2006. During the period 2010-2015 China will invest 66 billion USD in the renovation and construction of urban water supply facilities of which 43.2 billion USD is for new construction and renovation of the water supply network.
This paper investigates the present status of the urban water supply network, focusing on the application of plastic pipes in the water supply industry in China. In doing so the economics and in particular the whole life cost of plastic pipe systems will be compared to other materials and the potential use of trenchless technologies in the renovation of old systems and installation of new ones. The authors will also describe how to overcome a potential problem at the connection of plastic pipes to other systems and look forward to the prospect of using some of the new super-tough plastic pipe systems. Overall the use of these developments of high quality plastic pipes can be a great opportunity for the China water supply industry if the development is used in a professional manner.
