The Guogongzhuang Water Plant has passed a test run and is able to purify water that will be transferred to Beijing via the south-to-north water diversion project. The water plant, located in south Beijing, is the first major water plant built by the city in the downtown area for the project since 2000. It is expected to provide 500,000 cubic meters of water daily to meet the demand of nearly five million residents of Beijing. [Photo/Xinhua]
