Plover Cove Water Scheme
10.46. Work proceeded on all contracts for Stage I. These consist principally of an intake and pump house at Tai Po Tau, tunnels around the western head of Tolo Harbour to deliver stream course yields to a 900 million gallon storage reservoir at Lower Shing Mun, and a 60 million gallon per day treatment works at Sha Tin, all under the supervision of Consulting Engineers. Construction of a road tunnel through Lion Rock to accommodate three water mains under the carriageway and service reservoirs and attendant trunk mains, was under the control of the Waterworks Office.
10.47. Driving was in progress at three points on the tunnels between Tai Po Tau and Pai Tau Hang, and one of the minor tunnels was completed. Concreting was completed up to, and including, the pump floor slab of the Tai Po Tau pumping station.
10.48. On the Lower Shing Mun Dam site, works on the cut-off wall, filter layers, earth fill, bellmouth and gate shaft and tunnels continued.
10.49. At Sha Tin Treatment Works, good progress was maintained and concreting of the second pair of clarifiers had started.
10.50. Of the Lion Rock tunnel, required to accommodate the delivery mains to two service reservoirs on the southern slopes of the Kowloon Hills with a combined capacity of 41 million gallons, a further 2,400 feet, making a total of 2,500 feet, was driven. This is about half the full length. Concrete works for the Lion Rock and Tsz Wan Shan service reservoirs made good progress, and contracts were let for associated trunk and distribution water mains.
10.51. The design and the preparation of contract documents for Stage II, which includes the Plover Cove main and subsidiary dams, ancillary works and tunnels, was undertaken by the Consulting Engineers. Most tests were started at the Hydraulics Research Station on the Main Dam closure.
Shek Pik Scheme
10.52. A network of open channels and tunnels will bring the yield of 6,200 acres of indirect catchment into Shek Pik Reservoir. 101 miles of open channel and 3 miles of tunnel were completed.
10.53. Grouting of the cut-off of the Shek Pik Dam continued, while concreting of the diversion tunnel and construction of the bellmouth spillway were completed. A total of 5,620,000 cubic yards of selected filling material was placed, bringing the main dam to 90% completion.
