| dc.description.abstract | Penang Water Supply Corporation Private Limited has taken a few measures to improve its efficiency in the management of water supply. Several new departments and sections have been set up to handle some problems in water supply management. One of the newly formed sections, Water Lost Control Section under the Strategic Planning Department, is to handle the problem of non-revenue water (NRW). Among the strategies that have been taken to reduce the rate of NRW is the study regarding the contribution of meters inaccuracies in the water supply system to NRW so that a new policy and programme on meter change can be implemented to improve the overall accuracies of meters in the water supply system. For this purpose, a computerised meter testing programme has been carried out for meters recovered from premises of consumers through daily disconnections of water supply. From the meters tested, data concerning meter errors at several critical flow rates have been collected for a period of eight months. With further analysis of the data, the most economic meter change out period based on local water quality, consumption flow rate and water tariff structure has been established. Among the results obtained after thorough analysis of data collected are as follows: Contribution of meter inaccuracy of 15 mm PSM meters to NRW is 2.3% for Penang Island. The most economic life span of 15 mm PSM meter is five years. The conclusions that can be drawn from this study is that meter accuracy deteriorates with service life and the percentage error of meter in recording flow is higher at low flow rate compare with high flow rate. | |
