340. Despite bad weather work on the major 100-million-gallon irrigation dam at Ho Pui made satisfactory progress.
341. Construction of the lower dam at Tsing Tam made good headway, but work on the upper dam was rather slow until difficult foundation conditions were overcome. The two dams will impound a total of 30 million gallons on completion.
Shau Kei Wan Supply
342. To meet the needs of future development in the Shau Kei Wan area, a new service reservoir fed by a 27″ trunk main from Eastern Filters is required. The route of the trunk main was planned and an order placed for the pipes.
Extension of Kowloon Waterworks Depot-Argyle Street
343. A new three-storey block of offices to accommodate staff increases was completed. The design allows for the addition of a further three storeys should this prove necessary in the future.
Repairs to Pineapple Pass Dam
344. A slight but progressive movement of this dam has been taking place over many years and careful records have been kept.
345. The Consulting Engineers eventually decided that it would be advisable to take steps to prevent further movement by placing a wedge of suitably drained selected material over the whole downstream face of the dam, to provide additional weight. A toe wall was also necessary and the access road to Jubilee Reservoir skirting the foot of the dam had to be diverted slightly.
346. A contract was let, the toe wall and road diversion completed and a good start made on placing the earth wedge.
Water from China and the River Indus
347. Negotiations for a supply of water from China which had been opened towards the end of the previous year were continued and satisfactorily concluded by the signing of an Agreement at Shum Chun on 15th November, 1960, by representatives of the Po On County and the Hong Kong Government. It was agreed that:
(1) the Chinese Authorities would, for the time being, supply about 5,000 million gallons a year;
(2) the water would be delivered through a pipeline to the border and the Hong Kong Government would pay at the rate of 10 JMP (HK$.234) a thousand gallons.
