Underground water mains leakage and water seepage in buildings have long been causing great concern among governments, property management companies and occupants worldwide. To solve the problems, the location of such leakage, seepage and voids could be identified and properly diagnosed with imaging technique for finding an effective rehabilitation or repair scheme.
A webinar on Smart Water Technologies was held on 29 May 2020 at Underground Utility Survey Lab of LSGI. Mr Roger Wong, Assistant Director/ Development of Water Supplier Department, HKSAR Government, was invited to give a speech on “Water Loss Management Strategy in Water Supplies Department”. It was followed by sharing by Ir Dr Wallace Lai, Associate Professor of LSGI, on “Non-destructive Water Leakage Imaging and Diagnosis for Underground Utilities and Engineering Structures”. Speakers discussed the challenges and strategy of water loss management in the Water Supplies Department and presented our non-destructive diagnostic technologies in this area. Dr Lai also shared a live demonstration on these technologies. Over 270 online participants joined the webinar and many of them raised their questions at the end of the webinar.
