Water Supply In Hong Kong
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 (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 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. History Water rationing Until 1964 water rationing - the act of limiting water usage for each household by water providers - was a ...

Dongjiang
The Dong River is the easternmost main tributary of the Pearl River, flowing through Guangdong and Jiangxi in southern China. It's source is Mount Yajibo in Xunwu County in Jiangxi. Since 1960, water from the Dong has also been exported to Hong Kong. History Water exports In the early 1960s, the increasing demand of fresh water in Hong Kong was increasing due to a growing population. The government saw that the most efficient way to fulfill the unmet water needs was through the fresh water sources in neighboring Guangdong. On November 15th, 1960, The government reached an agreement with Guangdong authorities to take 23 million cubic meters of water a year from the Shenzhen Reservoir, which itself was connected to the Dong River. Later, additional pumping stations and dam works were built to further extend the supply. The new annual volume of water increased to 620 million cubic meters. More extensions in 1990 upgraded existing stations, leading to a new volume of 1.7 ...

Desalination
Desalination is a process that removes mineral components from saline water. More generally, desalination is the removal of salts and minerals from a substance. One example is Soil salinity control, soil desalination. This is important for agriculture. It is possible to desalinate saltwater, especially Seawater, sea water, to produce water for human consumption or irrigation. The by-product of the desalination process is brine. Many seagoing ships and submarines use desalination. Modern interest in desalination mostly focuses on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few water resources independent of rainfall. Due to its energy consumption, desalinating sea water is generally more costly than fresh water from surface water or groundwater, Reclaimed water, water recycling and water conservation; however, these alternatives are not always available and depletion of reserves is a critical problem worldwide. Desalinati ...

Reclaimed Water
Water reclamation is the process of converting Sewage, municipal wastewater or sewage and Industrial wastewater treatment, industrial wastewater into water that can be reused for a variety of purposes. It is also called wastewater reuse, water reuse or water recycling. There are many types of reuse. It is possible to reuse water in this way in cities or for irrigation in agriculture. Other types of reuse are environmental reuse, industrial reuse, and reuse for drinking water, whether planned or not. Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater. This latter is also known as groundwater recharge. Reused water also serve various needs in residences such as Flush toilet, toilet flushing, businesses, and industry. It is possible to treat wastewater to reach drinking water standards. Injecting reclaimed water into the water supply distribution system is known as direct potable reuse. Drinking reclaimed water is not typical. ...

Rainwater Harvesting
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a Rainwater tank, tank, cistern, deep pit (well, shaft, or borehole), Aquifer storage and recovery, aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water. Rainwater harvesting differs from stormwater harvesting as the runoff is typically collected from roofs and other area surfaces for storage and subsequent reuse. Its uses include watering gardens, livestock, irrigation, Drinking water, domestic use with proper treatment, and domestic heating. The harvested water can also be used for long-term storage or groundwater recharge. Rainwater harvesting is one of the simplest and oldest methods of Self-supply of water and sanitation, self-supply of water for households, having been used in South Asia and other countries for many thousands of years. Civilizations such as the Romans de ...
