The Happy Valley Underground Stormwater Storage Scheme (HVUSSS) is a key flood prevention project of the Drainage Services Department (DSD). The Phase 1 and Phase 2 of HVUSSS were commissioned in March 2015 and March 2017 respectively, relieving the flooding risks in the Happy Valley and Wan Chai areas.

HVUSSS includes a 60,000 m3 underground stormwater storage tank, a pump house, a fan room, a twin-cell box culvert and 15 no. of movable crest weirs. The innovative design of “Movable Crest Weir” controls overflow and discharge of stormwater to/from the tank based on the real-time monitoring data. The project also applies the concept of co-use of land by providing sitting-out areas for public enjoyment on the top of the pump house and adjacent to the fan room. Another key feature of the project is the water harvesting system, which reuses groundwater, irrigation water and rainwater for pitch irrigation and toilet flushing.
