China's largest water diversion project may start supplying water to Shandong Province by 2007 and Beijing by 2010, an official confirmed Tuesday.
The worsening water shortage in the two areas, caused by decades of drought, may be alleviated with water from the mighty Yangtze River in the South which will be diverted into the parched North, he said.
The water diversion project consists of three 1,300-kilometre canals that will carry water from the Yangtze along the eastern, middle and western parts of the country.
Zhang Jiyao, director of the State Council's office in charge of the South-to-North Project, told a national conference that ground will be broken in more places along two of the lines of the ambitious water diversion scheme, the largest of its kind in the world.
Before next year's flood season, construction of four new sections along the two lines will push the project further along the fast track. That would bring the total sections under construction to 13, since construction started in 2002 with an estimated investment of 124 billion Yuan (about US$15 billion).
When finished, the two water diversion canals will be capable of transferring 13.4 billion cubic meters of water a year.
