PUB, Singapore’s National Water Agency, is rolling out the first phase of Smart Water Meter Programme in Singapore. This will see the installation of 300,000 smart water meters in new and existing residential, commercial and industrial premises by 2023. The Smart Water Meters are designed to monitor and collect water consumption data. This will enable PUB to provide consumers with value-added services through a mobile customer app, such as understanding their water usage, and alerting households of suspected water leaks.
