Hong Kong's Drainage Services Department (DSD) has stepped up its flood prevention measures following heavy rainfall that triggered a Black Rainstorm Warning last Saturday (Aug. 2). Department Director Raymond Mok Wing-cheong revealed today (Aug. 4) that authorities received 120 emergency calls during the storm, with five serious flooding cases reported in North Lantau, Tuen Mun, Sai Kung, and Tsuen Wan - some with water levels reaching 200-300mm.

Mok reported that flood response teams managed to clear all incidents within 1-2 hours, restoring normal traffic flow. The department has implemented significant upgrades since the 2023 extreme rainfall events, including expanding emergency response teams from 160 to 180 units and establishing over 30 operational bases across the territory.

A key technological advancement this year has been the deployment of four high-capacity drainage robots, including the "Dragon Suction" model, which is capable of removing 800 cubic meters of water per hour. Two additional units of this powerful robot have recently been acquired, with Mok indicating potential for further technological investments based on operational needs.

The department's social media showcased one of the new robots, nicknamed "Drainy," in action. These mechanical reinforcements complement traditional drainage infrastructure improvements made during the annual pre-rainy season preparations. While acknowledging the challenges of climate change, Mok expressed confidence in Hong Kong's enhanced capacity to handle extreme weather events.

Authorities continue to monitor weather forecasts closely as the rainy season progresses, with the new robotic systems standing ready to assist in potential future flooding situations across Hong Kong's flood-prone areas.
