Smart Drainage System


In collaboration with the Chinese University of Hong Kong, LSCM developed a flexible and effective underground to above ground sensing and wireless network for real-time collection of water level and hazardous gas information from drainage and sewage systems for the effective monitoring of water level changes and gas concentration changes within drainage and sewage manholes.

Problem addressed

The traditional way to monitor and collect data of drainage system is to assign workers to go inside a drainage. It required a lot of manpower and workers' health may be affected as there might be hazardous gas inside the drainage. The system can monitor and collect data remotely. It analyses collected data and past data to issue alert for potential risks.

  • A unique sensing network for effectively collecting underground sensor data in an extremely severe environment
  • Specially design antenna for underground to above ground communication
  • An above ground mesh network is developed for backend system communication
Key impact
  • This project provides a very unique sensing network for effectively collecting underground sensor data in an extremely severe environment.
  • With the cloud computing and storage technologies, the accumulated big data collected by sensor modules become valuable assets for future data mining.
  • The wireless sensing network can largely reduce manpower costs and other costs related to routing inspections.
  • Drainage Management
Logistics and Supply Chain MultiTech R&D Centre (LSCM)

Logistics and Supply Chain MultiTech R&D Centre (LSCM) was founded in 2006, with funding from the Innovation and Technology Fund of The Government of the Hong Kong SAR, and is co-hosted by the University of Hong Kong, the Chinese University of Hong Kong and the Hong Kong University of Science and Technology. It aims to strengthen the local logistics sector and related industries by providing a one-stop resource for applied research and technology transfer, and to reinforce cooperation between the industry and research institutes to bring about meaningful and significant impact on the industry and the community. 

LSCM serves the industry by initiating research projects, contract research, as well as providing business matching opportunities, technology transfer and intellectual property commercialisation. LSCM initiates technology and knowledge transfer to the marketplace to promote industrial digitalisation, facilitate technology advancement and strengthen Hong Kong’s position as a leading logistics and commercial hub.
