Review on Application of GIS in Water Distribution System Planning & Designing

Water distribution systems constitute a vital part of civil infrastructure. The purpose of a water distribution system is to ensure the supply of water to the users at specified demand.� Water distribution system is a complex system that integrates several spatial features. Therefore, it is needed to use multi- support geographical information system which has capability of storing; managing and analyzing the large data set. The implementation of GIS can not only reduce the time needed for analyzing information but also can ensure a more efficient use of the resource with high flexibility in time and scale. In the field of water distribution system (WDS) analysis, the problems occurs that, survey of area, lying of a pipe lines and location of ESR. So the solution is that with the use of GIS tools. After the use of GIS tools we can get results like node elevation, length of pipes, location of ESR, and also create “inp� files for hydraulic simulation models. The current paper describes the study of various literatures on such a strategy of combining the use of GIS and various hydraulic simulation models like EPANET, WaterCAD etc.
