Application of GIS to Detect Vulnerability of Water Distribution System

Abstract

AbstractThe water distribution industry is facing challenges of water leakages in drinking water distribution networks. Mainly high pressure and the deterioration of ageing pipes and fittings cause the increase of the leak, and the consuming water and the number of bursts in the network. This study based on hydraulic and geospatial information system model has been suggested to estimate the probability of leaking for each pipe segment in the selected water distribution network. In this model, the likelihood of leaking is illustrated using pressure, age, length, diameter and slope of the pipe. The system is implemented with GIS tools, WaterGEMS, Google Earth Pro and Minitab software. Google Earth Pro is used to design the pipe network. The hydraulic model creates with WaterGEMS is integrated with ArcGIS. Minitab is used in elaborating the linear regression model, which is proposed to gain the leakage probability. The formed methodology is applied in identifying vulnerability ranges that have been identified for the pipe segments in the water distribution network. For the adducting results, a Geographic Information System (GIS) is used. Using the capabilities of this GIS model, the colour coded map represents the vulnerability ranges of the areas. The gained results can be used in detecting the most leakage areas and control pipeline leakage in the water distribution network. This methodology is developed to provide maximum protection against water leaks in the selected region.KeywordsGeographic information system (GIS)WaterGEMSGoogle earth proMinitab
