DSD wins eight awards at International Exhibition of Inventions of Geneva

22 April 2025

DSD has made an impressive achievement at this year's International Exhibition of Inventions of Geneva, winning eight awards for all entries, including one gold medal with the congratulations of jury, one gold medal, four silver medals and two bronze medals.

Renowned as one of the world's largest exhibitions exclusively dedicated to inventions, this year's event once again drew participants from 35 countries/regions. Over 1,000 inventions were evaluated by an esteemed international panel of experts.

This year's success has demonstrated DSD's unwavering dedication to the application of cutting-edge technology and its commitment to continually pushing boundaries and embracing innovation.

The list of awards for the eight recognised inventions of DSD is:

One gold medal with the congratulations of jury

Real-time territorial flood risk visualisation system leveraging Hydraulic Model Pre-run, Scenario Mapping and Mosaic Compilation technologies - Mosaic Model Map (M³)

Mosaic Model Map (M³) is a real-time, territory-wide flood risk visualization system self-developed by the Drainage Services Department, which effectively enhances the overall effectiveness in dealing with flooding incidents. M³ utilises real time hydrometric measurement data, precipitation and tidal forecast, to visualise the estimated flood risk situation in Hong Kong through hydraulic Model Pre-run, Scenario Mapping and Mosaic Compilation. This scalable and resource-efficient real-time flood risk visualization system will be mainly used to monitor flood risk trend, and facilitate DSD in its advance planning of emergency preparedness and enable DSD in timely resource deployment for speedy response to the possible flood situation.

One Gold Medal

The Smart Structural Integrity Monitoring System

The Smart Structural Integrity Monitoring System (LiFY-S) is co-developed by the Drainage Services Department, LeafIoT Technology Limited, and the Hong Kong Polytechnic University to enhance construction site safety in deep excavation. Key components of LiFY-S are designed to precisely measure structural micromovement of shoring system in real-time. This cutting-edge solution revolutionizes structural monitoring by integrating Artificial Intelligence of Things (AIoT) sensing, big data analytics, structural simulation, and digital twin technology, transforming traditional surveying methods into a real-time continuous AIoT-based monitoring system with a heightened developed sensitivity and a significant optimization in resources than conventional surveying techniques. LiFY-S sets a new benchmark for safety, efficiency, and innovation in structural integrity management.

Four Silver Medals

CRISPR-based Smartphone Microbial Assay for Rapid Testing - CRISmart

A CRISPR-powered smartphone platform for rapid microbial analysis in sewage. It detects E. coli and nitrifying bacteria on-site, enabling quick diagnostics to optimize processes. Portable and efficient, with more assays in development. (Jointly Developed by the Drainage Services Department and the City University of Hong Kong)
Intelligent Flood Alert and Emergency Response System - Flood Alert System for Tomorrow (FAST)

The "Flood Alert System Tomorrow" (FAST) is a system jointly developed by the Drainage Services Department (DSD) and the Pearl River Water Resources Research Institute (PRWRI) under the Pearl River Water Resources Commission of the Ministry of Water Resources of the People's Republic of China. The system integrates DSD's "Hydrological Information System" , PRWRI's advanced flood monitoring device and the Wading Line scheme in Mainland, which aims to enhance flood monitoring on low-lying road sections. When DSD receives alert messages from flood monitoring device, "Just-in-time Clearance" will be implemented by the emergency team deployed from Emergency Control Centre to immediately inspect and clear those blocked drainage channels. Also, it can alert road users, providing the drivers early warnings about potential flooding ahead and reminding them to be cautious when driving, thereby reducing the risk of vehicle breakdown. The pilot trial of this system will be arranged at five locations.
Machinery Analysis & Early System Trouble Resolution Operator - MAESTRO

Advanced predictive maintenance system using the META algorithm to monitor rotary machinery. Employs multimodal analysis and machine learning to detect and prevent mechanical failures before they occur.
Automated Software for Drainage Network Detailed Design

This design software is based on the Building Information Modeling (BIM) platform, allowing engineers to generate three-dimensional models of proposed drainage pipelines and manholes, as well as two-dimensional construction drawings on the BIM platform by simply inputting basic data. This design software can help engineers simplify the complex design process, save lengthy drawing time, and reduce the possibility of human errors, thereby saving costs and enhancing productivity. (Jointly Developed by the Drainage Services Department, Binnies and VIRCON)

Two Bronze Medals

MoShark Water Surface Mowing Robot - Wireless AI-powered Remote-controlled River Cleaning Robot

MoShark is a wireless robot powered by artificial intelligence, capable of autonomously monitoring water quality and cleaning rivers, regardless of tides and weather conditions. Holding over 100 Chinese invention patents, the robot has a carrying capacity of 150 kg. Its data, transmitted in real time on an online platform, enables intelligent and sustainable management of our river channels. Equipped with an AI camera, a millimeter-wave radar, the binocular vision-based target recognition algorithms, autonomous driving system and water quality sensors, MoShark can effectively identify and collect floating debris and vegetation within predefined route or designated zone. When its power is low or it is fully loaded, the robot can autonomously navigate to the charging dock for recharging, enabling year-round unmanned operation. (Jointly Developed by the Drainage Services Department and ORCAUBOAT)
Real-time Alert Platform for Inundation Detection - RAPID

RAPID is an AI-powered system that detects, tracks, and predicts flood events in real-time. It provides early warnings and monitors water levels continuously to help protect communities and infrastructure from flood damage. (Jointly Developed by the Drainage Services Department and Hong Kong University of Science and Technology)
