238. Tai Lam Chung Valley Scheme--Preliminary Investigations:-This work was referred to in items 242 & 243 of last year's report. The measuring weir built under Contract No. 23/48 was finally completed in May for $39,903.00 after extra work had been necessitated by damage to the unfinished structure caused by an unusually heavy flood in April. The continuous recorder was not ready before the end of the year but regular readings were taken from the gauge. Further rain gauges were also installed. Survey work continued intermittently as staff was available, and sites for the pipe lines, pumping station, filters, and service reservoirs were being surveyed.
239. The site of the proposed main Tai Lam Chung Dam was visited during June 1948 by Dr. F. Dixey, of the Colonial Geological Survey. He endorsed the local recommendation that the waterfall site was the best available and this was later agreed to by the Consulting Engineers.
240. Workshops, Instruments and Equipment: The new Meter Repair Shop, Bullock Lane referred to in para. 245 of last year's report was completed in May, together with a new blacksmith's shop, under Contract No. 263/47 with Messrs. Fook Lee & Company at a cost of $84,356.60. At Kowloon, a site was reserved for a new workshop and depot.
241. New machines which arrived from England under Indent Nos. 3505/1 and 98/47 were a Massey pneumatic hammer, a Kearns boring machine, and a Herbert Edgewick lathe. The pneumatic hammer was erected and tested.
Renewals and Improvement Fund.
242. New Pumping Plant for Tytam Tuk Pumping Station: The conversion of the steam boilers to oil firing, mentioned in para. 240 of last year's report, was abandoned and Indent No. 161/47 cancelled, as considerable corrosion was found to have taken place in the boilers. Instead, Indent No. 299/48 was placed through the Crown Agents for the Colonies with Messrs. W. H. Allen Sons & Co., Ltd., for two oil engine driven units capable of delivering 2,100 gallons per minute each, and one electrically driven unit capable of delivering 2,500 gallons per minute. This equipment, which will cost some $600,000, did not arrive during the year.
243. Improvements to Tsun Wan Supply:-The rapid development in the Tsun Wan area caused the existing water supply to become inadequate. Improvements to the supply by connecting the supply main to the Shing Mun catchwater and by laying a new 6″ main from the Catchwater to the Village, were in hand at the end of the year, 4,500 feet of 6" asbestos cement piping having been laid.
Other Works.
244. Pedestal Hydrants:-Sixteen new pedestal hydrants on the Island and eight on the Mainland were fixed in positions selected by the officer in charge of the Fire Brigade. The cost was charged to a Fire Brigade Vote.
