118. Taitam Tuk Scheme,— Second Section.—Except as regards a few minor details, this work was completed by the Contract date (21st October 1917).
Before giving a description of the works embraced in the Second Section, a brief statement of the inception of the scheme may be of some interest.
Up to 1901, all the storage reservoirs,—Pokfulam, Taitam and Wongneichong,—for supplying the City of Victoria with water, were at such an elevation as to afford a supply by gravitation. Their combined maximum capacity, with boards inserted to raise the levels of their respective overflows, amounted to 510,660,000 gallons. A fourth reservoir, known as the Taitam Byewash Reservoir, (maximum contents 26,301,000), also affording a supply by gravitation, was begun in 1901.
Unless the rainfall happened to be very abundant or its incidence, from a waterworks point of view, happened to be particularly favourable, the contents of the reservoirs were inadequate to maintain constant supply to the City throughout what is known as the dry season (October to April, inclusive). It was therefore necessary that additional accommodation for the storage of water should be provided.
In his Report on the Water Supply of the City of Victoria and Hill District, dated 9th May, 1896, Mr. F. A. Cooper, who was then Director of Public Works had proposed, among other works, the construction of two additional reservoirs, with a joint capacity of 110,000,000 gallons, on sites which were within the catchment area of the Taitam Reservoir and would therefore have afforded a supply by gravitation. He also alluded to the possibility of constructing two other small reservoirs in the Taitam Valley at a considerably lower level than the Taitam Reservoir, but, as pumping would be necessary to render the contents of such reservoirs available, he did not consider it expedient to advocate their early construction.
The futility of constructing further reservoirs within the catchment area of the Taitam Reservoir was however demonstrated in 1901. In that year, the rainfall during what is known as the wet season (May to September, inclusive) was the lowest on record, amounting to only 39.91 inches, as compared with an average for the previous 17 years of 65.42 inches. The result was that Taitam Reservoir did not fill, its contents amounted to only 322 million gallons whereas its capacity was 407 million gallons, and the dry season (1901-02) opened with only 345,953,000 gallons in store in all the reservoirs, clearly demonstrating that, in providing any...
