Achieving Low Unaccounted-For-Water through Reliable Supply to Customers and Efficient Network Management

Abstract

Since the early 1980s, PUB has been conscious of the need to manage the water supply network efficiently and to account for the amount of water distributed through the network. This concern is primarily motivated by PUB's goal to provide a high level of service to customers with reliable supply of water at affordable cost. With the strong support of the top management and the active participation of everyone in PUB, an Integrated Water Network Management System has been adopted to ensure that leakage in new networks is kept to a minimum through proper planning, design and the use of good quality materials that are installed with good workmanship. Losses in existing network are reduced through network management and leakage controls as well as accounting for water distributed with full and accurate metering. Consequently, these deliberate efforts have enabled Singapore to achieve one of the lowest Unaccounted-For-Water in the world (below 5%).
