the need to give effect to urban renewal, environmental improvement and long term highways development.

The Town Planning Office bases its work on the need to meet the demands of a population growing both in number and sophistication.
It uses data provided by the Census and Statistics Department and other Government departments and from field research to assess the forward requirements of the community and translates these requirements into the provision, on outline development and layout plans, of land for communications and for industrial, residential, commercial, community development and recreational use throughout Hong Kong.
WATER
The Need
3.38
The demand for fresh water for domestic, industrial and commercial purposes has risen from 25 million gallons per day in 1946 to 225 million gallons per day during 1975/76.
3.39
A review of the probable future increase in demand was carried out during the year, indicating an estimated growth rate of the order of 6% per annum during the remainder of the seventies and the beginning of the eighties. There was a recovery of the average daily demand in the latter half of the year, reflecting the general improvement in the economy, but the situation has not yet stabilised.
3.40
Apart from the overall growth of demand, the distribution of demand varies according to the pattern of development and redevelopment. Thus a continuous review of planning proposals is necessary so that resources can be developed and the associated treatment works, pumping stations, pipelines, service reservoirs and distribution systems can be built to satisfy the demand for water.
3.41
The variability in the rainfall into, and the volume of storage and size of catchment areas of the sixteen reservoirs which at present provide Hong Kong's fresh water supply, impose a need to plan the various draw-offs so that the productivity of the collective sources is maximised.
3.42
Planning for the development of the salt water flushing systems is similarly required. During the year, these systems supplied 41 million gallons daily for sanitary purposes.
The Machinery
3.43
In the early post-war years, staff was scarce, and the priorities were more obvious. There was no specific planning section in the Waterworks Office, and much of the thought on where new works were needed was done personally by the head of the Office. As the organisation grew, and planning became more complex, one planning officer was appointed in 1965. Planning is now undertaken by a staff of four or five engineers responsible to a
