 As the project progresses, the amount of water to be diverted to the north will increase from 8.9 km3/year to 10.6 km3/year to 14.8 km3/year.Water from the Yangtze River will be drawn into the canal in Jiangdu, where a giant 400 m³/s (12.6 billion m3/year if operated continuously) pumping station was built in the 1980s.The water will then be pumped by stations along the Grand Canal and through a tunnel under the Yellow River and down an aqueduct to reservoirs near Tianjin.
