December, 1960 to 11 a.m. on 2nd January, 1961. At Chinese New Year a full supply was provided for a period of 19 days between 14th February, 1961 and 4th March, 1961, when the consumption averaged 70.13 million gallons per day, with a maximum of 91.70 million gallons on Chinese New Year's Eve.
Rainfall
SUPPLY
302. The annual rainfall recorded by the Royal Observatory was 88.92 inches, 4.18 inches more than the annual average of 84.74. The fifteen rain gauges located in the various Waterworks catchment areas showed an average rainfall of 86.48 inches. The total rainfall for the seven months, October to April, was 17.75 inches against an average of 18.28.
Storage
303. At the beginning of the year the impounding reservoirs contained 3,547 million gallons of water, but by 5th May this had dropped to 2,282 million gallons, representing the minimum figure for the year and only 21.8% of total storage. Full capacity of 10,469 million gallons was, however, reached on 1st September and maintained for 18 days, with all the reservoirs overflowing on 7 days during this period.
304. The total quantity of water consumed in the urban areas rose to 23,570.92 million gallons and in the New Territories to 883.02 million gallons, representing increases over the previous year of 1,858.59 and 163.82 million gallons, respectively. The total number of hours of supply was 4,067.5 as compared with 3,703 in 1959/60, being an average of 11.1 hours a day as compared with 10.1 hours a day in 1959-60.
305. The maximum consumption of 89.86 million gallons in 1 day was 3.48 million gallons less than the previous year's recorded maximum.
Distribution
306. Improvements to the distribution system and the longer hours of supply for most of the year resulted in significantly fewer complaints, the majority of which were received, as was to be expected, during the period of severe rationing in April and May.
Water Analysis
307. The standard of purity aimed at is high: complete absence of coliform organisms in a 100 c.c. of treated water, and to maintain this standard, Waterworks personnel systematically take samples for testing by the Government Pathologist.
