plant specifications were issued in respect of a further three. Design work commenced on eight further projects. Notable amongst the new installations was Muk Wu pumping station, at the border, which accepts and repumps the water coming into the Colony from China. Here, new plant, totalling 84 m.g.d. capacity, was installed and the 60 m.g.d. plant, temporarily borrowed from the River Indus flood pumping station, was returned and reinstalled. The whole operation was completed within 12 weeks against the deadline imposed by cessation and restoration of supplies from China.
Mechanical Section
8.52. Pumping from the wells at Muk Wu continued throughout the year and preliminary investigations were put in hand for the installation of automatic unattended pumps to replace the temporary diesel powered units.
8.53. Extensive large diameter pipework complete with valves was installed at the River Indus pumping station to permit direct pumping of Chinese water from this point to Sha Tin. This work was associated with the pumping arrangements introduced at Plover Cove.
8.54. The Larner-Johnson valve regulating the flow of supplies from Shek Pik reservoir developed serious trouble which could not be rectified on site. The five ton valve was dismantled and shipped from Lantau to Hong Kong for overhaul in the workshops. The overhaul was completed and the valve reinstalled.
8.55. The training workshop for female meter repairers at Jordan Valley was completed and the first group of fifteen girls engaged. Results were encouraging and a further fifteen girls were recruited.
Electrical Section
8.56. Maintenance programmes were devised and inaugurated during the year.
8.57. The number of high voltage plant overhauls carried out was higher than usual, due to the necessity to operate plant associated with major supply schemes as early as possible and often whilst construction works were in progress nearby. In-service training of instrument mechanics and trade apprentices continued.
