A water harvesting system is incorporated in Happy Valley Underground Stormwater Storage Scheme for collecting groundwater, irrigation water and rainwater for reuse purposes (The picture shows the Happy Valley Underground Stormwater Storage Tank)
Reclaimed water is being used for toilet flushing in the changing rooms in the Happy Valley Recreation Ground
Water Reclamation
In 2018-19, more than 1,800 cubic metres reclaimed water has been generated per day for non-potable use. The major water reclamation facilities are located in the Ngong Ping STW, Sha Tin STW and Pillar Point STW.
Furthermore, the Shek Wu Hui STW is being upgraded in stages to Shek Wu Hui Effluent Polishing Plant to enhance its treatment capability to tertiary treatment level. Part of the tertiary treated effluent at Shek Wu Hui Effluent Polishing Plant will be further polished by the Water Supplies Department as reclaimed water and supplied to north-east New Territories, i.e. Sheung Shui and Fanling, for toilet flushing and other non-potable use.
