In pure numbers, 7.5 out of every 10 glasses that are drank in Beijing contain this water from the south.
You never miss the water till the well runs dry... Luckily that problem is being solved in China, thanks to the mega water diversion project that has directly benefited over 120 million people.
Check out the aerial views in this video to see how many miracles China's South-to-North Water Diversion Project has made and will make.
In Beijing, three in four cups of water people drink today is from the Yangtze River, thanks to a project called South-to-North Water Diversion Project.
The south-to-north water diversion project, the world's largest, was designed to take water from China's longest river, the Yangtze, through eastern, middle and western routes to feed dry areas in the north. Over the past five years, the middle and eastern routes of the project have benefited more than 120 million people.
Veteran engineer Li Shuncai witnessed the development of the world's largest water diversion project.
