APPLICATION OF DIGITALIZATION AND INTERNET OF THINGS （IOT） TECHNOLOGY IN NETWORK LEAKAGE MANAGEMENT IN MACAO WATER

The new urban areas and towns in the Guangdong-Hong Kong-Macau Greater Bay Area are characterized by huge populations, varying scales of water supply enterprises, and inconsistent management practices. Among them, pipeline leak control commonly faces operational and managerial challenges. With the strong promotion of carbon reduction at the national level, water supply enterprises need to adopt more proactive measures to meet carbon targets and achieve carbon neutrality, with leak control being a key control point. Currently, most water supply enterprises adopt traditional management measures and pipeline leak detection methods. Based on the practical experience of leakage management in Macao's water supply, the article summarizes five specific measures for leakage management. It emphasizes the integration of water leakage management, digitalization, and intelligent management approaches. Some specific new leakage management methods and their effects are introduced by examples of the application of Internet of Things (IoT) technology in leak detection and pressure transient management in the pipeline network
