Abstract
Non-revenue water (NRW) is a major challenge for urban water security in Jordan. Quantifying of leakage is a difficult task in intermittent supply systems. This study aims to provide a structured analysis to determine the volume of leakage and its components in Madaba9s water distribution network. The study also offers recommendations to reduce the physical losses as an important component of water losses through an infrastructure, repair, economic, awareness and pressure (IREAP) framework as a way of systematically engaging the NRW challenge in Jordan. The real loss sub-components were analysed using Burst and Background Estimates (BABE), and field records of the failures in the network. The potential impact of interventions to reduce losses were measured for efficiency/efficacy by analysing pressure management, chronic leakage detection surveys and response time minimization. The findings showed that Madaba9s NRW amounted to 3.5 million m 3 in 2014, corresponding to a loss of 2.8 million USD to the utility, of which 1.7 million USD is the cost of real losses. The reported failures in Madaba accounted for 37.2% of the total volume of real losses which can be improved by enhancing response polices and asset management, while the unreported failures constituted 26.6 and 36.20%, respectively, which could be reduced by pressure management and active leakage control.
