reservoirs, one at Stanley Mound and the other near the New Gaol, were completed, tested and put into use in July with unfiltered water.
15. The following lengths of piping were laid: - 397 feet of 6", 8,056 feet of 5", 592 feet of 4" and 1,767 feet of 3"
16. A scheme to supply filtered water to the Queen Mary Hospital was completed during the year. A pipe line 8,551 feet long was laid from the existing 750-foot level service reservoir near Po Shan Road to a new service reservoir above the Hospital site. This reservoir has a capacity of 102,000 gallons and a top water level of 675 feet A.O.D. 762 feet of 4" and 1,050 feet of 3" piping were laid for the distribution system and fire service from the service reservoir to the Hospital and Quarters.
17. In Kowloon and New Kowloon the following lengths of mains were laid: 2,550 feet of 12", 335 feet of 10", 544 feet of 6", 982 feet of 4", 832 feet of 3", 340 feet of 2" and 70 feet of 1". In addition 3,858 feet of subsidiary mains were laid in back lanes.

22. A commencement was made with the laying of the second 24" diameter trunk main for the Shing Mun Valley Scheme. The pipes, which were made locally from British steel, were all delivered during the year and comprised 12,837 lineal feet of heavy section and 3,449 lineal feet of light section. The laying of 12,050 lineal feet of the heavy section was practically completed during the year.
