Water has always been a precious com modity in Hong Kong and the government has had to devise major schemes to ensure *** that sufficient supplies are available for both domestic and industrial use. In November, the Governor officially opened High Island Reservoir, a massive engineer- ing feat which cost $1,350 million. High Island, with a projected storage capacity of 273 million cubic metres," was formed by damming and draining a channel between the island and the New Territories' main- land, and replacing the seawater with fresh- water. It is Hong Kong's second reservoirs reclaimed from the sea. The first, Plover Cove, with a present capacity of nearly 230 million cubic metres, was built in the 1960s and later expanded. "In addition, Hong Kong has 15 conventional reservoirs and one of the world's largest desalination" plants, together with treatment works, pumping stations and a network of under- ground tunnels and submarine pipelines. There is generally an abundant annual rainfall, but a change in weather. pattern can significantly affect water*** storage. At the start of 1978, residents had a limited water supply of 10 hours a day until restrictions were lifted in April However it is seldom necessary to in- 2 troduce water rationing, particularly as China now provides approximately 30 per cent of Hong Kong's needs. This results from a further agreement "signed in November which will enable Hongpadala Kong to meet consumption demands up re to 1982. The Water Supplies Department***** is continuing to plan for the future by investigating proposals for recycling water, reverse osmosis för desalination and the development of minor catchment areas.

Previous page: Early in the year, the water level had dropped dramatically at this reser voir at Tai Tam, on Hong Kong Island. Left! But umbrellas were necessary when early rains boosted water supplies.
