Beijing makes efforts to protect water supplies at source
Water resources are quite limited in China, but a lack of water itself is not the only challenge. Pollution threatens the few resources there are. Liu Xinqing traveled to Beijing’s largest reservoir to take a look at the efforts to protect water supplies at their source.
The reservoir in Miyun county some 70 kilometers to the north of Beijing is the only surface source of drinking water for the capital. It supplies about two thirds of Beijing’s drinking water, so obviously protection work here is extremely important.
Hu Minggang, deputy director of Miyun Reservoir, said, "We strictly follow water safety regulations and for years we have kept the water quality here at grade two - which is acceptable for drinking water."
Ensuring water quality is the number one issue. Water samples are collected from over 40 spots every week for testing in this lab. The fight isn’t an easy one. The reservoir covers over 80 square kilometers and there is a large population living around it. That makes for a very high pollution threat.
Hu Minggang, deputy director of Miyun Reservoir, said, “For historical reasons, there are still 30,000 residents living around the reservoir, but we have been working with the local government to treat the waste water from residents, discourage them from using polluting substances in farming and encourage them to grow water-cleansing plants.”
Mr Hu told us that tourists are also a big concern, because some of them manage to find their way to the reservoir with the help of local residents. Monitors in this room reach almost every place at the reservoir. This enables staff to quickly locate people entering without permission.
Zheng Chunhong, reservoir worker, said, "Our major task here is to find tourists entering without permission, collect garbage they leave behind and explain its potential risk of water pollution."
A large number of these workers patrol the reservoir everyday - putting them on the front lines of the fight against water pollution. The efforts are clearly worth it. Major incidents of water pollution earlier this year in Guangxi in south China and in Songhua River in northeast China several years ago - have been hard lessons and it should be avoided in the future.
MiYun Reservoir is one of the best protected water sources in the country because it is so close to so many living in the capital city. But the situation nationwide is not as optimistic. The threats to water quality posed by China’s rapidly expanding economy will remain a tough challenge.
