10.55. At Pui O, the excavation for the pump house was completed, and concrete work started on the basement and walls.
10.56. A 200,000 gallon wash water tank at the treatment works overlooking Silver Mine Bay was completed. The excavation over the site was almost finished and concreting commenced on the footings, walls of the sedimentation tanks, chemical house, filters and service reservoir.
10.57. 8 miles of twin 30" steel welded pipelines were laid in a trench in the sea bed between Silver Mine Bay and Sandy Bay on Hong Kong Island and subsequently tested.
10.58. On Hong Kong Island, the excavation for the pumping station and balance tank at Sandy Bay was completed, and tenders were received for their construction. 155,000 cubic yards of bed rock excavation was carried out in preparation for the 30 million gallon service reservoir at Mount Davis.
10.59. 65% of the trunk mains to be laid on the Island were supplied and 2,600 feet laid.
10.60. All villagers displaced by the reservoir construction were resettled.
The Integrated Water Scheme
10.61. The preliminary investigation was completed, and the full report on the scheme was received.
10.62. In the meantime, all contracts for stage I of the scheme were let. This stage consists of an intake and pump house at Tai Po Tau, tunnels around the western head of Tolo Harbour to deliver the stream course yields to a 900 million gallon storage reservoir and 60 million gallon per day treatment works at Sha Tin. The water will thus be pumped through Lion Rock Tunnel to two service reservoirs with a combined capacity of 41 million gallons on the southern slopes of the Kowloon hills. The excavation for the treatment works was completed, some 100 feet of the tunnel under Lion Rock had been driven, excavation for the two service reservoirs was finished and concreting of the walls started. All other contracts were in the preliminary or early stages of construction.
10.63. Authority was given to the Consulting Engineers to proceed with the preparation of the contract documents for stage II, the principal item being the construction of a dam across the entrance to Plover Cove to convert this sea inlet into a fresh water lake providing storage for 30,000 million gallons of usable water.
