plicated C.M. meters. It was anticipated that the ultimate replacement of the C.M. by the J.S.M. type of meter will in time reflect a saving in maintenance cost per meter.
Distribution and mainlaying
10.21. Work continued on extensions to serve new developments, replacement of defective pipes, enlargements of under-sized mains, and alterations necessitated by road re-construction.
10.22. Approximately 40 miles of pipes, varying from 2" to 27" in diameter, were laid and included 58,850 feet of asbestos cement pipes for salt water flushing supply distributions, as well as galvanized iron pipes for sub-mains up to 4" diameter, cast iron pipes up to 18" diameter, and steel mains over 18" diameter.
10.23. The more important mains laid during the year, other than those in connexion with particular projects, were:
(a) 1,472 feet of 18″ cast iron and 422 feet of 24" welded steel outlet main from Bowen Road Service Reservoir, via Kennedy Road to Queen's Road East.
(b) 1,940 feet of 10" asbestos cement and cast iron main between Stanley Mound Tank and the New Chung Hom Kok Service Reservoir.
(c) 2,500 feet of 12" asbestos cement flushing water distribution mains for the North Point area.
(d) A combined total length of 7,400 feet of 18" cast iron mains were laid in Canton Road, Yim Po Fong Street and Gascoigne Road, to improve the distribution of the three areas.
(e) 4,159 feet of 15″ asbestos cement main to carry flushing water to the Ma Tau Wei Housing Estate.
(f) Approximately 20,000 feet of 6" asbestos cement and galvanized iron pipe to provide an unfiltered supply from the Jubilee Reservoir to the Sha Tin Estate of the Resident Staff for Plover Cove Scheme, and to improve the supply to Sha Tin village.
(g) 1,116 feet of 24″ welded steel trunk main in Castle Peak Road through Tsuen Wan.
Service reservoirs
10.24. All service reservoirs were cleaned, sterilized, and inlet and outlet valves tested and overhauled as required. Inspections showed that no major repair was required.
10.25. Fresh water service reservoirs at King's Park and North Point were completed, as well as the salt water reservoir at Tai Wo Ping.
Catchwaters
10.26. The usual troubles on catchwaters due to minor landslips following heavy summer rains were experienced, but no major damage
