The city as a sponge: solutions for precipitation increase due to climate change

Jiangsu Sponge City Technology Research Institute and KWR to set up joint research projects

On October 28, Hong Hai and Dragan Savic signed a Memorandum of Understanding stating that their research institutes – the Jiangsu Sponge City Technology Research Institute (JSCTRI) in China and KWR, respectively – want to jointly set up projects to develop and apply ‘sponge city technologies’ in the urban environment in China and Europe. Technologies that increase a city’s water absorption capacity are necessary to cope with climate change.

Climate change is bringing longer periods of drought and heavier, unpredictable showers in many places. The approach currently used in many cities – to drain precipitation away from the city as quickly as possible – is often inadequate and makes it impossible to put the fallen water to good use during subsequent droughts. New technologies are needed to store water in the city. The city needs to start working like a sponge, rather than an impenetrable desert of concrete and asphalt.

CEO Hong Hai signed the MOU on behalf of JSCTRI.

Sponge city technologies

JSCTRI is a Chinese government research institute established in 2019 that focuses on the development and application of so-called ‘sponge city technologies’ The collaboration between JSCTRI and KWR will accelerate research through pilot and demonstration projects in so-called proof of value applications. Following the signing, both institutes mapped out their cooperation opportunities.
