Abstract: In the process of urbanization, water pipe network construction and optimization in various areas of China is one of the major problems. There are some problems in existence, for example cost much, the pipe laying are not optimized and low economic benefits and so no. A new method to solve pipe network optimization based on geographic information system and genetic algorithm is put forward. By establishing the mathematical model, using genetic algorithm for pipe network layout optimization, and combined with the GIS integrated management of spatial information and processing power, finally we get a set of more reasonable network layout scheme, so as to achieve the aim of saving construction cost.
