Water supply and sanitation in Hong Kong is characterized by water import, reservoirs and treatment infrastructure. Though multiple measures were made throughout its history, providing an adequate water supply for Hong Kong has met with numerous challenges because the region has few natural lakes and rivers, inadequate groundwater sources, a high population density, and extreme seasonable variations in rainfall. Thus nearly 80 percent of water demand is met by importing water from mainland China, based on a longstanding contract. In addition, freshwater demand is curtailed by the use of seawater for toilet flushing, using a separate distribution system. Hong Kong also uses reservoirs and water treatment plants to maintain its source of clean water.
