Beijing is seriously short of water. With an increase in urban population and extension in urban functions, the water shortage has become a new issue that urgently requires a solution. It is learned from relevent organs that in recent years, Beijing has implemented measures such as preserving water resources, collecting rainwater, diverting water from other regions and calling for water conservation to ensure water supply for rural and urban residents, industry and agriculture and realize Beijing's sustainable social and economic development.

The water capacity of reservoirs increases and the quality improves

Preserving water is particularly important for a city like Beijing that faces a severe shortage of water resources. Beijing's mountain areas are rich in both landscape, and water source conservation and protection areas. The numerous urban residents who spend their holidays and carry out entertainment and leisure activities there bring economic benefits on the one hand, but also leave rubbish and waste water on the other hand.

Focusing on preserving water sources, Beijing has set aside 6,000 square kilometers of area as water source conservation areas and implemented strict water resource protection regulations to control pollution at the source. Three lines of defense – ecological restoration, ecological management and ecological protection, have been put in place around reserviors to develop eco-friendly, minor drainage areas.

In order to improve the quality of water in Miyun Reservoir to the standard of surface water, Beijing's scientists and engineers have carried out research on a water eutrophication prevention and control system for the reservoir and put forward a number of technical measures to control area pollution sources and reduce pollution sources in the inner lake. The techniques, which integrate engineering, management, biological and ecological measures, have had a noticeable effect in protecting water sources.

Thanks to the implementation of a batch of technical solutions to improve water quality and the construction of demonstration projects, Miyun Reservoir has not only maintained normal water supply, but also increased its water capacity again while ensuring good water quality. As of the end of 2008, the reservoir's water capacity had exceeded 1.1 billion cubic meters and the water quality was above the Class-II level.

Guanting Reservoir, which was once one of Beijing's two major water sources, was removed from the drinking water supply system in 1997 due to water pollution. Given the level of pollution in Guanting Reservoir, Beijing's relevant organs have gradually approved two key scientific and technological projects and over 20 specific projects, and formulated a systematic engineering plan to restore the water in the reservior. The plan has already passed an inspection organized by the Ministry of Water Resources.
