the quantity received from China doubled. All storage reservoirs were overflowing during 3 days in September and 3 days in October, so that the dry season started with the maximum quantity of 16,816 million gallons in storage, excluding the supply from China.
7.05. Considerable repairs to catchwaters were necessary particularly as a result of tropical storm 'Agnes' in September when damage to the Shek Pik catchwaters alone amounted to an estimated $2 million. The bulk of the blockages were cleared and slopes stabilized and in some cases channels decked over to help prevent future damage. It was also decided to install a radio transmission system between all the major control gates on Lantau to facilitate tighter control.
7.06. Complete overhaul and repainting of control gates was put in hand and normal maintenance of catchwaters and routine inspection and cleaning of service reservoirs, access roads and station surrounds continued. Several new service reservoirs were put into use during the year including Tsz Wan Shan, Beacon Hill High Level, Kwun Tong High Level, Chung Hom Kok and the western half of Mount Davis.
Distribution Section
7.07. 24-hour water consumption increased by 8 per cent compared with last year and averaged over 113 million gallons daily, with an all-time record of 138.6 million gallons on 31st August.
7.08. Corresponding with Government planning areas, four major supply zones in Kowloon and New Kowloon were created and consideration was given to re-adjusting the existing supply zones on Hong Kong Island.
7.09. Work continued on extensions to serve new development, enlargement of undersized and defective mains and alterations necessitated by road construction. Apart from mains laid on specific projects approximately 44 miles of pipe were laid to distribute fresh and salt water.
7.10. Systematic waste detection was carried out on a greatly increased scale and 86 areas were checked. A number of major leaks were discovered and repaired resulting in a daily saving of nearly two million gallons.
Housing Service Section
7.11. With separate metering now being required for all new flats and tenements there was an increase of 44% in the number of meters installed.
