But, the Hong Kong winter drought, the rainfall is unstable, depends
upon the natural rain water, with difficulty thorough settlement water

The Hong Kong once was insufficient as a result of the water storage
capacity, but has implemented the severe system water. In June, 1963,
each four days supply water for four hours. Another serious drought,
from 66 year in August to 67 years in June, continuously ten months.
On the other hand, our pond water in storage ability is limited,

例子2:
Providing an adequate water supply for Hong Kong has always been difficult because there are few natural lakes, rivers or substantial underground water sources. The annual rainfall averages 2 214.3 millimetres but this is insufficient to meet current demands — the average daily consumption of potable water during 2002/03 being 2.63 million cubic metres. The principal functions of the Water Supplies Department are to collect, store, purify and distribute potable water to consumers, and provide adequate new resources and installations to maintain a satisfactory standard of water supply. The department also supplies seawater for flushing.
