(h) Trunk Mains. Approximately 5,000 ft. of 30" diameter steel pipe laid in Kwun Tong and Ngau Tau Kok Roads for the proposed new reservoir at Ngau Tau Kok.
(i) The new pumphouse at Garden Road was completed, and the new pumping equipment was installed and put into service. The existing equipment was transferred from the old station which has since been demolished.
(j) Good progress was made on the construction of the new catchwaters and ancillary works, contracts being let for approximately 51,500 ft. of catchwater and 16,700 ft. of tunnel. The settling basin dam and tunnel at Sham Tseng were completed and work continued on access roads and new sections of the catchwater, including further tunnelling work.
334. Delay was experienced, however, on construction of the northern group of catchwaters, owing to opposition from neighbouring villagers who feared that the catchwaters would deprive them of water during the dry season. Efforts were made to explain the scheme to the villagers but the dispute is still unsettled, and work on this particular section of the catchwater system was at a standstill.
335. During the year approximately 31,600 ft. of catchwater channels were constructed, 12,000 ft. of tunnel driven and approximately four and a half miles of access roads built. Survey work continued for the construction of the balance of the catchwater channels.

336. Following the Consulting Engineers' report on the site for a proposed dam at Shek Pik, a contract was drawn up with a specialist firm with the object of rendering the ground suitable for a dam foundation by the application of a clay cement grouting method used successfully under similar conditions in Europe. A test length was to be treated in the first instance, and if successful the work would be extended over the full area. A jetty and various buildings including staff quarters were constructed, road construction put in hand and, following the arrival of plant and personnel from Europe, work on the test section commenced. Good progress was made, the 'boxing off' of the test section being completed and grouting commenced. To avoid loss of time in the event of the tests proving successful, borings were sunk in the vicinity of the dam site to investigate the quantities of suitable material available for use in the dam and surveys carried out at proposed sites for the pumping station and treatment works.
