10.93. Much time was spent in investigating and constructing schemes for improving the inadequate yield during the winter, for example, by recovery of wash water at Tsuen Wan Filters, pumping from the Shing Mun River at Sha Tin and by sinking wells in the urban areas and setting up water-selling kiosks.
10.94. Much time was also spent in calculating how hours of supply might be varied to meet existing or potential water storage positions, and a Report on Water Supply 1963-68 was prepared in June, which recommended:
1. Continuation of Tanker Supplies
2. Negotiations for a supply of water from the East River in China.
3. Acceleration of the River Indus Pumping Scheme.
4. Examination of the possibilities of flood-pumping and desalination.
10.95. In the field of planning, plans were drawn up for fresh- and salt-water supply to Kwun Tong, Yau Tong, Ho Man Tin and Beacon Hill areas in Kowloon and to Aberdeen and Pok Fu Lam on the Island.
10.96. Some consideration was given to supplies in Castle Peak and Sha Tin areas and work was begun on a complete revision of the proposals for fresh- and salt-water supplies in the Tsuen Wan/Kwai Chung area.
10.97. Basic data were obtained, by site measurements, for the design of salt-water flushing supplies in industrial areas and proposals were prepared for the resiting and enlargement of Kai Tak Salt Water Pumping Station.
Hydrological Section
10.98. In the past Waterworks has collected data from rain-gauges and stream-gauges and use has been made of the records. However, systematic hydrological studies have only begun during the present year with the appointment to Waterworks Office of a hydrologist and supporting staff.
10.99. The Hydrological Section was set up so that the individual outputs of existing and proposed water-supply schemes in the Colony could be more accurately assessed, so that a rational system of inter-connexion of the individual schemes could be determined and so that data would be available to enable a programme of construction to be drawn up to ensure that resources at any time would be able to meet demand.
