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 users at specified demands. The main objective of the research works is to study the exiting water supply system of Bawaliyari village, Taluka Dholera, source of the water and then planning water distribution system using ArcGIS. This paper addresses the use of ArcGIS for mapping and planning water distribution network. GIS based tools will be used for the digitization of village (polygon), water distribution network (polyline) and nodes (point) which are important from the water distribution point of view. Two tools have been used i.e.3D analyst & Spatial analyst for extracting elevation information from Shuttle Radar Topography Mission (SRTM) image at various locations of the village including Nodes’ locations which has been used to create a contour map of the village and there after fixing the location of the Elevated Service Reservoir (ESR). Data generated in ArcGIS such as topography, nodes’ elevation, length of the pipe etc., can be used for designing the efficient and economical water distribution system as they can been readily imported as input files for the hydraulic simulation models like EPANET, Water CAD and Water GEMS as well as the programs like Branch and Loop.
