GENERAL
299. The most significant achievement of the year was the completion of an agreement with the People's Committee of Po On County of China for the supply of water from their new reservoir situated about 2 miles north of the Hong Kong border near the township of Shum Chun. The agreement was signed on 15th November, 1960 and the supply of water from China began on 5th December, 1960. By the end of the year under review 2,309 million gallons of water had been received from China and this quantity was supplemented by 1,175 million gallons pumped from the River Indus into the same pipeline. The engineering aspects of this project are described in paragraphs 347-349.

MAINTENANCE AND DISTRIBUTION
300. With development proceeding apace, particularly the establishment of more resettlement and low cost housing estates, the steadily increasing demand for water necessitated considerable extensions to the distribution system.
301. At the beginning of the year the hours of supply were restricted to four a day, but the very dry winter and the lack of early summer rains made it necessary to reduce the period to three hours daily between 24th April and 6th May. However, when it was found that the change from four hours to three hours caused hardly any reduction in the daily consumption and only resulted in numerous additional complaints, the hours were increased to four a day on 7th May. After heavy rains on 8th June the supply was further increased to ten hours a day on 10th June. The rains continued until well into September, and with a satisfactory storage position at the beginning of October and the additional water from the River Indus and from China, the ten hours a day supply was maintained for the rest of the year. Over Christmas water was available from 4 p.m. on 24th December, 1960 to 11 a.m. on 27th December, 1960, and over the New Year from 4 p.m. on 31st

Jordan Valley Dam for Salt Water Flushing Supply
This dam, which is 90 ft. high, will impound 54 million gallons of stream water supplemented by sea water pumped during periods of low yield. [para. 334(3)]
Ma Lau Tong (Kwun Tong) Dam for Salt Water Flushing
This scheme is similar to that at Jordan Valley but for 14 million gallons of flushing water. [para. 334(4)]
