Waterlogging Prevented by Sponge Infrastructure
Summary
"The Wuhan Sponge City Programme focuses on reducing waterlogging and increasing water quality via the ecological remediation of existing urban water systems and the construction of blue and green spaces to capture and store rainwater. The first phase of the project, from 2015 to 2017, will see the development of 389 so-called sponge projects, such as urban gardens and waterbodies in parks, roads, residential communities, and commercial and public buildings. These will cover 38 m2 of the city and provide habitat for plants and wildlife.
By the end of the pilot period, two new rainwater pump stations will have been constructed, providing at least 25% of the city’s water. Furthermore, 13 ports and channels will be repaired, drain pipelines will be improved, and at least one lake will be ecologically restored. Overall, the project is expected to reduce the occurrence of severe waterlogging events from once annually to once in 10 years in the pilot zone, a strong start to adapting the city to climate change."
