7.05. At the end of the year 5,291 million gallons of water was held in storage compared with 12,029 million gallons at the same time last year. The yield from the catchment areas was much lower than last year but the quantity drawn from China was greater. Due to the agreement by the People's Council of Kwantung Province to increase the quantity to be drawn from Sham Chun, the quantity available during the supply period became 16,800 million gallons and at the end of the year the amount still due was 5,375 million gallons. The June rainstorms filled most of the storage reservoirs but a period of unusually dry weather followed and the normal dry season started with only 13,510 million gallons of water in storage.
7.06. The 24-hour a day supply which had been generally maintained for 897 days from the 1st September, 1964 was discontinued on the 15th February when the supply of water was restricted to 16 hours a day; e.g. from 6 a.m. to 10 p.m. Restrictions were necessary in view of the poor storage position which resulted from a continuation of the dry spell which began in the summer and were aimed at reducing consumption by 5%. This has in fact been attained.
7.07. Consumption on a 24-hour a day supply increased by 10 per cent over the previous year and averaged 126 million gallons a day, with an all-time record of 149.5 million gallons on the 15th August.
7.08. Considerable damage to Waterworks installations was caused by the rainstorm on the 12th June. In particular, the supply for Hong Kong Island was seriously affected by the flooding of Sandy Bay Pumping Station, damage to the Sandy Bay balance tank and the wash-out of the supply main from Aberdeen. This resulted in the supply on Hong Kong Island having to be restricted to 8 hours a day for 3 days. Catch-
