Application of GIS and MCDM on Natural Environment Effect toward the Durability of Water pipe: A Conceptual Study

Abstract

Utility is considered as one of the most important systems in all countries. A structured network is defined as a network comprising specific components and subsystems. Leakage of water pipes is a common problem around the world. It is understood that water is a valuable resource to all living things. The aim of this study is to estimate the durability of water pipe based on natural environment factor in Selangor, Malaysia. There are several proposed objectives listed such as to identify the parameters that affect the durability of the pipe, to develop GIS modelling to predict the durability of water pipelines and to generate durability of pipeline prediction maps to the study area. The criteria such as temperature, soil moisture, soil type, acidity, resistivity, landuse and slope were selected from the expert opinion and also from the previous study. The method used is Analytical Hierarchy Process (AHP) and GIS. AHP technique were used to calculate the weightage for each of the criteria. In this study, map of the mildsteel waterpipe durability estimation can be produced using ArcGIS.
