Friday is an important day for China's South-North water transfer project, with water beginning to flow from the Danjiangkou reservoir in central China to Beijing.

The water will travel more than 1,400 kilometers before it reaches the capital. The channel takes advantage of natural geographic conditions, so the water can flow by itself, at a speed of one meter per second. It will take 17 days to complete the whole journey. Water quality will be monitored by the minute to ensure that it reaches or exceeds the country's second best water quality level.
It's the biggest project of its kind in the world.
