Cove and design work on a new pumping station and pipeline to deliver water from the Lower Shing Mun Dam supply basin to the North Conduit at the outlet of Jubilee Reservoir—a first step in the integration of the Plover Cove Scheme with existing resources. Contracts for the Plover Cove main dam and for the main tunnels were awarded in December and good starts were made by both contractors.
10.76. Work on the Tai Po Tau to Sha Tin section of the scheme was pressed on with the aim of benefitting from the summer rains of 1964, but with disappointing results. At Tai Po Tau the pumping station was ready for the installation of the pumps and the foundations for a 'Fabridam' were concreted. A 'Fabridam' is an inflatable structure constructed of neoprene-coated rubber which deflates when the water stored behind the dam reaches a predetermined level and thus avoids flooding upstream of the dam.
10.77. Fair progress was made on the Lower Shing Mun Dam but a bonus was negotiated with the contractor in order to accelerate completion of the dam. The delivery tunnel to the Sha Tin Treatment Works from the Lower Shing Mun Dam supply basin was completed and progress on the civil engineering works and plant erection at the Sha Tin Treatment Works and Pumping Station proceeded satisfactorily.
10.78. However, progress on the essential tunnel link between Tai Po Tau and Sha Tin was poor and although the main tunnel was holed through, much work remained to be done to complete the lining, intake shafts and intake works. The construction of the Tau Pass to Tai Po Tau culvert was commenced but progress here was also slow.
10.79. The laying of pipelines to deliver the filtered water proceeded satisfactorily. 1,200 ft. of two 48″ diameter and one 54″ diameter steel pipes were laid from the treatment works to the northern portal of the Lion Rock Tunnel. The tunnel was successfully holed through and the lining virtually completed. Work began on one of the three mains through the tunnel and the two reception service reservoirs at Lion Rock totalling 41 million gallons in capacity were completed but for minor site improvement works. 27,000 ft. of major distribution mains were laid from the Lion Rock Reservoirs into Kowloon, and a new 15-million-gallon service reservoir at Tsz Wan Shan to supply the developing area north of Kai Tak was 75% completed.
10.80. Irrigation works associated with this scheme in the area between Tai Po Tau and Sha Tin proceeded satisfactorily with the construction of 27 small diversion dams and 15,300 ft. of channel and pipelines.
