The Secretary for Development, Mrs. Carrie LAM, announced the declaration of 41 waterworks structures within six pre-war reservoirs (namely Pok Fu Lam Reservoir, Tai Tam Group of Reservoirs, Wong Nai Chung Reservoir, Kowloon Reservoir, Shing Mun Reservoir and Aberdeen Reservoir) as monuments on 18 September 2009 to recognise the high historic value of these waterworks facilities.
Mrs. LAM and Chairman of the Antiquities Advisory Board, Mr. Bernard CHAN, officiated at a ceremony in Tai Tam Tuk Raw Water Pumping Station to celebrate the declaration. They also performed a plaque unveiling ceremony on the same day to open the Tai Tam Waterworks Heritage Trail.
Also celebrating the monument declaration were 120 secondary school students. As well as joining the celebration, they also conducted a series of scientific tests on the water quality of the Tai Tam Group of Reservoirs to mark World Water Monitoring Day 2009, which is an annual event aiming at increasing public awareness and involvement in protection of water quality.
