The Trail was established for the declared monuments in the Tai Tam Group of Reservoirs to help the public appreciate the history of water supply and the waterworks structures in Hong Kong.
Upon completion, pressure of water demands from urbanisation spread, from central and western districts to the eastern side of Hong Kong Island, was gradually released.
The Tai Tam Water Supply System could basically meet the needs of the Hong Kong Island at that time.
The Tai Tam Group of Reservoirs is a reminiscence of the water supply history of early Hong Kong.
With regard to the engineering techniques used, the system used in Tai Tam Reservoir relied much less on gravity flow, which only accounted for about 20% of the total capacity of the ultimate fresh water supply.
There are many waterworks structures with precious historic value in the Tai Tam group of reservoirs along the trail, the following ones have been declared monuments including valve houses, bridges, staff quarters etc.
[6] Guided tour for Tai Tam Waterworks Heritage Trail is introduced by the Commissioner for Heritage's Office in late September 2009 to encourage young people (only 12–18-year-old people can join the tour) to appreciate these centenary monuments and learn more about the history of Hong Kong's water supply.
Between 10 October 2009 and 19 December 2009, there will be guided tours at Tai Tam Waterworks Heritage Trail every Saturday morning, starting at 10.30am and 11.30am respectively.
