Potential of Water Pipeline Bursting Using Stochastic Approach in Geographical Information System

Abstract

A pipe bursting is one of the major problems in water distribution systems. This problem resulted in losses, particularly in water wastage or shortage and infrastructure damages. Furthermore, several organisation and authorities do not have systems or database for water management monitoring, leading to a difficulty in monitoring and update the condition of the pipeline. Geographical Information System (GIS) can help to develop a geospatial database for the water distribution network; to determine the high potential of pipe to be burst and identify the areas affected by the pipe failure. In this study, the potential of pipe to be burst is determined using a stochastic approach to get the probability of the potential failure, which based on four factors; age, pressure, material and diameter of the pipe. A valve isolation trace function from ArcGIS tool is then used to determine the area affected by the pipeline failure. Results from the analysis are to produce maps of high potential pipeline bursting and the affected areas. The findings could help the management to monitor the conditions of the water pipeline regularly, detecting early warning, preparation for the pipe’s replacement and notify the residents to make initial preparations if the pipe has a potential to burst.
