Abstract

Factors such as physical characteristics of pumps, transmission lines and tanks play an important role in operating and managing water supply systems (WSS). Therefore, it is required that these systems are evaluated by taking into consideration their current status. The objective of this study is to carry out structural and technical performance evaluation for pumped-WSSs via Analytical Hierarchy Process (AHP). For this purpose, main factors such as pumping station, structural condition and transmission line, sub-factors such as pump physical, operational characteristics, pump and water tank building etc. were considered. Weights for each factor were calculated based on pairwise comparison matrices of factors composited by opinions of the experts. The AHP model was applied to 10 pumped-water supply systems that currently provide service. It is thought that the AHP model introduces significant innovations since it takes into consideration the variables to reflect and reveal the general state of the WSS.
