DSD Media Briefing on the Application of Powerful Pumping Robots

The Drainage Services Department (DSD) held a media briefing on 12 August 2025 to introduce the application of powerful pumping robots.

DSD Chief Engineer, Ms Yvonne LO Chau-ling, introduced the department is actively applying innovative technology in its drainage work. At the beginning of this year, the department introduced powerful pumping robots to enhance the efficiency of handling flooding incidents and strengthen the capability of response to emergency. During the black rainstorms events from the late July to early August, the department consistently deployed "Mobile Powerful Pumping Robot" to handle flooding cases, successfully supporting multiple affected locations. Moreover, the department will also consider further additions of Mobile Powerful Pumping Robots based on actual circumstances to meet the demands for emergency response and handling flooding incidents.

Senior Engineer, Mr Leo CHAN Cheuk-chung, explained the operating principles, functions and usage of the "Mobile Powerful Pumping Robot" and "Amphibious Pumping Robot" series to the media. Compared with traditional equipment, these pumping robots are smaller in size and highly mobile. They are operated by trained workers who are responsible for setting up temporary drainage hoses to quickly remove large amounts of accumulated water from flooding areas. The water will be discharged through temporary drainage hoses into nearby stormwater drainage systems, rivers, or directly into the sea.
