Capital absorbs 'sponge city' ideas

Beijing is collaborating with the US state of Wisconsin to build a "sponge city" by creating an ecological circle, from the removal of water to its sustainable return to nature.

The Chinese capital city's water authority, together with The Water Council nonprofit organization in the United States and the Wisconsin Economic Development Corp, hosted a water conference on Wednesday to transfer the US technology, following a similar one in Nanjing, Jiangsu province, two days earlier.

On the theme of "One Water, One World", the meeting was the first event between the two countries on a water solution, with a special focus on building a "One Water" sponge city circle.
