Kunshan City of Jiangsu Province was recently listed as one of the country’s three “model sponge cities”.

The Jiangnan Lixiang community of Kunshan is piloting the “sponge” system, an ecologically friendly drainage system with rainfall gathering tanks installed along the roads. The rainwater on the building roofs and roads will run into the roadside tanks first. Aquatic plants will be used to remove nitrogen and phosphorus and purify the rainwater before it flows into the terminal tanks.

Besides, the city has taken the lead in Chinese cities by applying the technologies for the “sponge city” initiative in building the Central Elevated Expressway. The road landscape under the expressway features numerous tanks, placed every hundreds of meters, in order to restore and purify the rainwater, with each tank at 1.5 meters wide and 15 meters long.

The city has around 100 “sponge city” projects, under construction or completed, of various functions and types, such as inside the parks, public buildings, residential communities, and along the roads.

Moreover, Kunshan plans to host the innovation demonstration center for the “sponge cities”, a cooperation project of Jiangsu province and Victoria state of Australia with an investment nearly 100 million yuan ($16 million), in a bid to promote the Australian practices into China.
