WSD Deploys Smart Robot to Clear Sediment in Shau Kei Wan Tanks Without Cutting Water Supply

2026-11-10 17:29 Last Updated At:17:29

Some residents in Shau Kei Wan were recently affected by a water main incident that caused sediment to enter building water tanks, affecting water quality. The Water Supplies Department (WSD) is actively following up on these cases and has deployed a dedicated smart robot to clear the sediment directly from the tanks.

The robot operates without draining the tanks, sending workers into confined spaces, or suspending the water supply. Traditional cleaning methods, however, require shutting off the water and emptying the tanks before workers can enter. The entire process, from risk assessment, ventilation, and gas testing to manual cleaning and refilling, is time-consuming and can disrupt residents’ water supply.

Manual cleaning requires three to four workers, whereas the robot needs only one or two. Its materials and design do not compromise water quality, making the process faster and safer. Since it operates without interrupting the water supply, disruption to residents is kept to a minimum.

One of the two highlight events, the Night Parade, will kick off first on Saturday, 14 November, at 8:30 pm. Local artists have created 5 illuminated giant puppets and 18 sparkling carnival costumes, the highest number of costumes in the event’s history. The parade team has expanded to more than 150 performers, a scale 1.5 times larger than in previous years. This year also marks the first time that a juggling team, a marching band and a professional rope-skipping troupe will join the Night Parade, alongside dazzling dance and live music, turning the Causeway Bay night sky into a glittering stage.
