223. After the re-occupation it was found that all the plant and materials obtained in 1941 had disappeared and no trace of them has since been found. Repeat orders were therefore placed with the manufacturers under Indents Nos. B.4/10-12-14. Some slight modifications were made on the original design to bring it in line with modern practice. By the end of the year only the steel reinforcing bars and some piping had been received.
224. Replacement of Boring Plant for Tai Lam Chung Valley Scheme. The investigation by drilling of foundations for proposed dam sites in the Tai Lam Chung Valley was in progress before the war, and is referred to in paragraphs 179-180 of the 1939 Departmental Report. This work had not been completed prior to the war. After the re-occupation it was found that all the drilling plant had disappeared and it could not be traced. Replacement plant was ordered under Indents Nos. B.4/15 and B.4/16-B.4/16(3), most of which except that under B.4/15 had arrived by the end of the year.
225. Replacement of Chlorine Cylinders. Before the war the Waterworks had about 600 high-pressure steel cylinders for the conveyance of the liquid chlorine used on the sterilisation of the Water Supply. These cylinders circulated continuously between the Colony and the United Kingdom. Empties were shipped to the United Kingdom in lots of about 100 for testing, refilling and return to the Colony.
226. At the end of the war most of the cylinders had disappeared and replacements had to be obtained. Orders were placed under Indents Nos. B.4/1 and B.4/5 and by the end of the year 420 full cylinders had been received.
227. Public Works Extraordinary. (B). New Works-Waterworks. Purchase of Motor Transport. As all pre-war transport vehicles had disappeared during the war, provision was made for replacing them. In January 1947 three Jowett cars were purchased for use as Staff cars. The other Staff cars in use and the load-carrying vehicles were obtained from the Controller of Land Transport, and payment for the cost of them has not so far been called for.
228. Tai Lam Chung Valley Scheme-Preliminary Investigation Expenses. This work was referred to in paras. 179-180 of the 1939 Departmental Report and in para. 131 of this Report. The area was visited in 1940 by Mr. Binnie of Messrs. Binnie Deacon & Gourley, the Consulting Engineers for the
