238. Pokfulam Road Pumping Station:-The three existing steam-operated pumps at Pokfulam Road Pumping Station are about thirty years old and consequently very expensive to maintain and operate. It has therefore been decided to obtain three new diesel-driven pumps and to keep the two best existing pumps as standby sets. Tenders were accordingly called for and Indent No.48 of 1948 was forwarded to the Crown Agents in January, 1948, for three Sulzer pumps driven by Mirrlees T.L.A. Diesel engines.
239. Stanley Supply:
Supply: The existing five-inch diameter supply main from Tytam Tuk Pumping Station to Stanley proved unable to deliver sufficient water to meet the increasing demand at Stanley. Indent Nos.16 and 18 of 1947 were therefore forwarded to the Crown Agents for eight-inch diameter steel and asbestos cement pipes and fittings to replace the existing pipes. Some of this material had arrived by the end of the year.
240. Tytam Tuk:-Conversion of Boilers to Oil Burning: With the prevailing high price of coal, pumping costs at Tytam Tuk Pumping Station have been excessively high. Very considerable saving in running cost can be effected by converting the boilers from coal burning to oil burning, and Indent No.161 of 1947 for the necessary equipment was accordingly forwarded to the Crown Agents in June 1947. Nothing had been received by the end of the year.
241. Staff Quarters:--The reconstruction by the Architectural Office of the war-damaged Waterworks bungalows at Shing Mun and near Kowloon Filters was in progress at the end of the year. 1460 feet of 14" galvanised iron piping for the former, and 880 feet of 1" galvanised iron piping for the latter were laid to provide for the water supply.
242. Tai Lam Chung Valley Scheme:-Preliminary Investigations:-The geophysical survey carried out by Messrs. Le Grand Sutcliff & Gell Ltd. was completed in June 1947, but boring work was continued throughout the year. Altogether 46 bores were drilled through 1395 feet of soft material and 886 feet of rock, and over 429 feet of cores were recovered. Reports on the geophysical survey and the borings were submitted to the Consulting Engineers, Messrs. Binnie, Deacon & Gourley, but a final decision as to the site to be adopted had not been reached by the end of the year.
Steps were taken to obtain more information as to rainfall and run-off in the valley by the erection of two rain gauges and a new sixty-foot long flood weir. The latter, being built under Contract No.23 of 1948 by Messrs. Kwong Wing, was nearing completion at the end of the year.
The survey of the valley was continued. Replacement of boring plant ordered under Indent No.B/4/15 was still outstanding at the end of the year.
