Where does Beijing's urban drinking water source come from?

The drinking water source in Beijing comes from Miyun Reservoir.

Miyun Reservoir is located at 13km north of Miyun County, Beijing, and in the hilly area of Yanshan Mountains. It was completed in September 1960. It covers an area of 180 square kilometers, with Miyun Reservoir as the center and Fiona Fang 200 kilometers.

Miyun Reservoir, with a storage capacity of 4 billion cubic meters and an average depth of 30 meters, is the largest and only drinking water source in Beijing. Miyun Reservoir has two main inflow rivers, namely Baihe River and Chaohe River.

20 1 1 In order to ensure that Miyun Reservoir is not polluted, Miyun County has also put forward six major protection measures: water protection, river protection, mountain protection, forest protection, land protection and environmental protection, and established 7,000 forest rangers, more than 2,000 water managers and village-level cleaners.

An environmental protection team composed of more than 300 female environmental protection team members. Around Miyun Reservoir, the water environmental protection team set up by villages and towns has absorbed more than 1800 local residents, so that there is a village-level cleaner every 85 meters along the embankment, working for more than 6 hours every day.

After years of effective water source protection, Miyun has formed a beautiful natural environment. The content of negative oxygen ions in the air in the reservoir area is 40 times higher than that in the urban area, and the air quality remains at the first level all the year round. Miyun reservoir has also become the only pollution-free drinking water source in Beijing, and the water quality has reached the second-class standard for direct drinking.
