Project Objectives:
- Digitise mechanical water meter data of non-domestic premises, to enable the timely detection of leaks and anomalies through the application of IoT and data analytics technologies.
- Promote the use of high-resolution water-use data to control leakages and to inform building managers’ water-conservation decision-making.
- Enhance the level of water sustainability understanding within the property management sector.
Project Description:
Out of 3 million+ water-user accounts, 315,315 accounts are billed to non-domestic premises. While these accounts make up 9.87% of WSD’s total accounts, they use over 40% of Hong Kong’s total freshwater. This project aims to target the top 10% highest usage sites of each type of building. Through IoT and data analytics technologies, we aim at digitising mechanical water meter data and visualising high-resolution water-use data, so as to help building managers to identify, in a timely manner, water leaks and water-use anomalies in their premises. We will also conduct capacity-building workshops to enhance building managers’ water sustainability knowledge.
Target Deliverables in 2024/25:
- A report on the KE outcomes and impacts achieved
- An impact case study based on the relevant template of the UGC’s Research Assessment Exercise (RAE)
- Social media posts, infographics and/or posters on LinkedIn and for the buildings
- Data visualisation dashboard for building/ site managers
- A water-use report for each participating building
- A Water Efficiency Calculator for non-domestic premises in Hong Kong
- An article on the KE outcomes and impact in layman terms (in both
- English and Chinese) for distribution to the media
- Records and photos of seminars and sharing sessions with building managers and WSD
