Water supply and sanitation in Hong Kong : ウィキペディア英語版 | Water supply and sanitation in Hong Kong
Providing an adequate water supply for Hong Kong has always been difficult because the region has few natural lakes and rivers, inadequate groundwater sources (inaccessible in most cases due to the hard granite bedrock found in most areas in the territory), a high population density, and extreme seasonable variations in rainfall. Thus about 70 percent of water demand is met by importing water from the Dongjiang River in neighbouring Guangdong province. In addition, freshwater demand is curtailed by the use of seawater for toilet flushing, using a separate distribution system. == History == Water supply in Hong Kong initially came only from local sources, including numerous small dams built in the valleys of the territory.
