Operation and Maintenance
10.55. Two new pumping stations were commissioned. The division now operates a total of 56 pumping installations. The total installed horse-power throughout the Colony increased by 8.1%.
10.56. During the year, a shutdown of the Sha Tin Treatment Works and Tai Po Tau pumping station enabled inspection and maintenance to be undertaken: this was a particularly useful opportunity to inspect items of plant normally inaccessible. Two diesel pumpsets were temporarily installed at the Tai Po Tau pumping station during the shutdown to ensure a continuous supply of water to the Tai Po Tau treatment works supplying the Tai Po and Sheung Shui districts.
10.57. An extensive series of flow tests were carried out on the delivery main and aqueduct system between Tai Po Tau Pumping Station and Lower Shing Mun Supply Basin to provide information necessary for specifying the duty of the pumps for an extension to the pumping station. Similar test results on the pumping mains between Sha Tin Treatment Works and Lion Rock Reservoirs were used by Planning Division for the design of the Sha Tin Lion Rock Pumping System.
10.58. Power supplies at Tai Po Tau Pumping Station were arranged to uprate the capacity from 2500 kVA to 7000 kVA for the proposed extension of this installation. The permanent switchgear for control of the three 30 m.g.d. pumpsets was installed and the temporary switchgear removed.
10.59. An additional pumpset was transferred from another location and installed in the Sha Tin temporary pumping station to boost further the supplies of filtered water to Kowloon, and increase the output of the temporary station from 16 to 24 million gallons per day.
10.60. Two new 2,600 horse-power pumpsets, each capable of pumping 30 million gallons of water per day, were installed and commissioned in the Sha Tin Treatment Works Pumping Station increasing the nominal installed capacity of pumping plant to a total of 10,860 horse-power. These pumps together with the temporary pumps give a grand total of 13,410 horse-power and deliver 105 million gallons of filtered water per day to Kowloon from the Plover Cove Complex.
10.61. Telemetry and control equipment installations for the Plover Cove Scheme were extended, and the automatic control of the Sha Tin
