10.69. On the Mainland, the saltwater mains were extended as required at Kwun Tong, Hung Hom and Wong Tai Sin.
Shek Pik Water Scheme
10.70. The main construction work on Lantau Island was virtually completed and the scheme was inaugurated by H.E. the Governor at a ceremony at Shek Pik on the 28th November, 1963.
10.71. In addition to the main dam, the pumping station at Pui O and the Filtration Plant and Service Reservoir at Silvermine Bay were completed under Consulting Engineers. Final calibration and commissioning of the automatic filter-control equipment continued and in the meantime the filters were operated under manual control but the quantity which could be extracted was small due to the dry conditions.
10.72. A total length of 57,440 ft. of catchwater channels and 17,030 ft. of tunnels had been completed at the end of the year and only the final portion of Catchwater 'C' was outstanding.
10.73. At Sandy Bay the 1.5-million-gallon balance tank and gauge basin were almost completed and work continued on the installation of the pumps, switchgear and electric motors. A diesel driven pump was installed temporarily to enable the scheme to be used. At the 30-million-gallon Mount Davis Reception Reservoir concreting of the west half proceeded and excavation of the eastern half was completed and concreting started. At Kennedy Town site formation was completed and construction commenced on the 6-million-gallon service reservoir. All trunk mains on Hong Kong Island to carry the Shek Pik water into the existing system were completed making a total of 34,400 ft. of steel mains varying from 21" to 48" diameter of which 31,000 ft. were put into service.
Plover Cove Water Scheme

Stage II of this scheme includes, under the supervision of Consulting Engineers, the construction of the Plover Cove Dam, a pumping station at Tai Mei Tuk and the tunnels between Plover Cove and Tai Po Tau which serve the dual purpose of collecting run-off from the Pat Sin Range and delivering water to and from the main reservoir. During the year when work began on the second stage it became undesirable to continue to draw a distinction between Stages I and II, so the two stages were combined.
10.75. New works which began during the year included office and domestic accommodation for the Resident Engineers' staff at Plover
