The increase of 38% over the previous year must be largely attributed to the increased consumption, the greater quantities pumped from the Shum Chun Reservoir and Indus River, together with the water pumped from Tsuen Wan Pumping Station to Jubilee Reservoir Supply conduit to augment the quantity extracted from Shing Mun and the Kowloon Reservoir Group.
10.15. Waste detection covered the detection of leaks and repairs of defects to valves, house connexions and the distribution system, as well as investigations of high consumptions, unauthorized usage of water, etc. 10.16. 41 of the 93 waste detection areas were examined and tested, and an estimated saving of 74,900 gallons per hour was achieved by the repairs effected.
Metered services
10.17. The following table gives the position over the last three years:
1959-60 1960-61 1961-62 New Meters Installed Mainland 2,267 4,874 2,677 Island 1,073 1,107 975 Total 3,340 5,981 3,652 Service 71,941 77,922 81,574The increase in the number of meters installed in 1960-61 was attributed to the Hong Kong Housing Authority's So Uk Estate. The figure for 1961-62 which returned to the same order as that quoted for 1959-60 confirms this, as no meter installation of this magnitude was carried out during the past financial year.
Workshops
10.18. 1,843 separate items of work, including 59 orders from other departments, were carried out. This work at times fully committed the resources of the workshops, with the result that 41 orders had to be executed under contract by local firms. This is 19 orders less than that placed in 1960-61, as a result of the decision to order the majority of standard special castings required for mainlaying from the United Kingdom.
10.19. 50,190 meters were overhauled, representing 63.5% of all meters in service.
10.20. 18,000 Kent "J.S.M." meters were received, and 8,400 put into service to replace the older of the less efficient and more com-
