Water loss meter tracking GIS mobile application

Abstract

One of the most challenging tasks in providing water services is proportion of water loss or known as non-revenue water (NRW). NRW is water supplied to the consumer, but it is lost before it reaches the consumer. The losses of NRW is related with water billing and water produced by local agencies such as Air Selangor. One of the ways to overcome NRW is by changing inaccurate or malfunctioned water meter, but the local department’s water meter still uses the manual method. An innovative geospatial mobile application for water loss meter tracking system was developed at AIR Selangor s, Shah Alam. The main stages used in this study were identifying the problem, designing the app, developing the app and lastly evaluating the app’s performance. Selected officers and contractors of the department agreed with the recommendation made by the authors to develop a digitized system based on the current system. The app has technical capabilities to improve the current system which uses pen and paper to manage water loss via meter system at the site. This geographical information system (GIS)-based application could also update and locate all the coordinates of water meters efficiently so that the contractor can easily find the malfunctioned water meters. The respondents agreed that the design and practical functions developed in the app are relevant in dealing with the water problem.
