Project Title: Next-generation Imaging Technologies of Rapid Leakage Diagnosis of Underground High-Pressure and Large Water Mains in Carriageway
Hosting Institution: The Hong Kong Polytechnic University (PolyU)
Abstract: On average, 15% of precious water resources is lost in HK underground water mains
networks. According to Policy Address 2018 and 2021, The HK Government pledges to
reduce the water loss to 10% by 2030. Rapid road-based imaging and diagnostic
technologies and data-driven solutions are of high demand to improve efficiency of
leakage detection while disturbance to water supply and the public is minimized. With the
support by Water Supplies Department (WSD) of HKSARG and industrial sponsorship,
the project aims to develop next-generation imaging technologies of rapid leakage
detection of underground high-pressure and large water mains in carriageway where
most large water mains are buried. Machine-learning based change-detection and
pattern-recognition solutions will be developed to formulate levels of sensitivity and
specificity at different leakage magnitudes will be formulated in a 25,000 sq,ft test Q-Leak
Center of WSD (designed by the PC in 2020-2021), and validate the identified leakage in
two pilot sites. The validated leakage in the two sites, after repair by WSD, will be closely
monitored by building a data-driven framework. It is expected the developed technologies
and solutions can be applied in whole Hong Kong and commercialized elsewhere where
similar problems exist.
