The Water Supplies Department launched a new integrated mobile app "eWater", consolidating the existing WSD mobile apps into a one-stop personalised digital water services information platform with an optimised user interface and enhanced features. Through “eWater”, users can access a wide range of water supplies information such as real-time push notifications on latest updates on water suspension and resumption, anytime and anywhere. Users can also manage their accounts, and apply for various water services directly within the app, including taking up and closing of water accounts, settling water bill payments via Faster Payment System with e-banking mobile apps, applying for e-bill services, and viewing billing summaries and payment histories without the need to deal with the submissions by post or in-person, providing a one-stop experience for users to access WSD services in an easy and flexible manner. “eWater” shows the amount due on the latest water bill with push notification options for bill issuance and payment deadlines. Users may also subscribe to specific concerned districts or housing estates to receive location-specific water suspension and resumption alerts, ensuring they stay informed about any water supplies status in their concerned area.
