Smart Sensor Monitoring System for Water Leakage Detection above APM Tunnel, HKIA

I&T Wish Smart Sensor Monitoring System for Water Leakage Detection above APM Tunnel, HKIA
(REF: W-0601)
Matched I&T Solution
Trial Project
Summary and Challenges
  • Currently, routine inspections are required to identify water leakage or seepage in the wet zone above the APM tunnel. This process is labor-intensive, time-consuming, and may not detect initial or intermittent leakage in a timely manner. Conventional inspection relies heavily on visual observation, which can be affected by lighting, humidity, and accessibility limitations.
  • The main challenge is to design and implement an automated, reliable sensor-based monitoring system that can operate under a humid and high-temperature environment, provide continuous data transmission, and trigger early warnings when abnormal water leakage and ponding are detected.
Expected Outcome
  • The proposed system will utilize moisture, humidity, and water presence sensors integrated with IoT communication for real-time monitoring. Data will be visualized in the central E&M monitoring platform, enabling early detection of potential leakage and facilitating preventive maintenance actions.
  • It is expected to reduce manual inspection frequency, enhance reliability of tunnel protection, and improve maintenance efficiency.
Expected Trial Duration 12-month
