Sponge City Construction was an initiative launched by the Chinese government as an approach to tackle water related problems in the cities of China.
The Qian'an Sponge City Construction PPP Project concerns wastewater treatment, water supply, river restoration, municipal transportation, country parks, information platforms and other facilities.
The municipal government decided to undertake this project under a public-private partnership (PPP) model.
The concept of a sponge city was born in 2013 and refers to cities that are like sponges: with an infrastructure that collects excess rainfall and integrates flood control in urban planning.
