Page 175. Apart from six special days, e.g. Chinese New Year, when it is considered desirable, a full supply was not possible at any time of the year. In fact the average hours supply per day throughout the year were 9.5 as compared with 13.5 last year and 15.5 in 1949/50.
Page 176. Restriction. Previous reports have given the distribution of water as between Island and Mainland, but owing to the difficulties of operation on a five hours supply, it was found necessary to open a bye-pass from the cross harbour main to city distribution, which being unmetered caused fictitious figures to be recorded for the cross harbour main supply. The correct amount of water used on the Island could not, therefore, be calculated.
Page 177. With the early end of the rainy season it was evident that a very dry winter was in store and that if a repetition of the 1929 shortage were to be avoided, early enforcement of very heavy restrictions was necessary. The supply was, therefore, cut to 9 hours on October 12th and on November 16th it was still further reduced to only 5 hours per day. The winter yield was substantially as estimated and, with restrictions remaining unchanged to the end of the year, the reduction in storage took place at the rate anticipated.
Page 178. Restriction to 5 hours caused many difficulties in distribution and for the first week many people were without water. By opening some of the control valves in advance of the official time, and leaving difficult supply areas on for an extra hour when necessary, most of the difficulties were, however, overcome.
Page 179. Particularly difficult areas on the Island were the North Point and Shaukiwan districts and the Central and Western low level areas. Some improvements were, however, possible and the benefit from the replacement of the feeder in King's Road between Happy Valley and the North Point Service Reservoir
