Wireless Sensor Network for Metropolitan Smart Drainage System

Solution Wireless Sensor Network for Metropolitan Smart Drainage System
(REF : S-0113)
Features of Products / Solutions
  • Underground environment has been a challenging environment for developing a wireless network for smart drainage system. Sensing devices would wear out quickly because of high humidity and high concentration of corrosive gas inside the manholes.
  • Another challenge is to investigate how the wireless signals can penetrate iron manhole cover to reach a base station kilometers away and then transmit to the frontline staff through 4G/5G network.
  • The system can automatically adjust the frequency to innovatively transform the manhole cover itself as part of integrated wireless network so that the data collected can be sent back to the base stations at roof top of nearby buildings.
  • A micro gas sensor within a completely sealed environment is introduced so that both the durability and energy efficiency of the smart drainage system can be improved.
  • The large-scale, real-time, smart and wireless drainage system is the first of its kind in the world and proven feasible in safeguarding the drainage system of the city.
Matched Trial Project
  • Since last August, a hundred wireless underground devices have been installed in manholes of both stormwater drainage and sewerage systems in Kowloon Bay, forming a comprehensive system to monitor the water level and gas concentration of designated zones
  • Through the wireless signal transmission and big data analysis, the smart drainage system enables frontline staff to take proper and timely action on gas emission, illegal wastewater discharge, and blockage.
  • The prevention of explosion and flood risk, the early detection of environmental pollution, the study of change of water level and flow velocity will become more effective.
