“Now in Jiangbei District, there are fewer and fewer black, smelly, and garbage rivers, and its water quality is also on the rise.” Ningbo Housing and Urban-Rural Development Bureau releases this Monday afternoon that Ningbo’s “Sponge City” Pilot Project has achieved some notable success: by the end of June 2019, 126 projects have been completed in the pilot area, with completion rate reaching 84%; completed drainage area has registered twenty-three square kilometers, accounting for 74% of the total area of the pilot area. According to construction requirements for sponge cities, Ningbo’s pilot project is expected to be finished in this October.

In April 2016, Ningbo made it to the list of pilot cities for the “Sponge City” Pilot Project. The Cicheng- Yaojiang area, covering an area of 30.95 square kilometers, was the first in Ningbo to be determined as pilot area. Each pilot zone is required to control 80% of its total annual runoff in 70% of its area, and the final goal is to build the zone into one with “sponge” effects where there is no pool of water on the street when it rains lightly, no risk of flood when it rains heavily, no black or smelly rivers, as well as alleviation on the “heat island effect”.

Over the past three years, Jiangbei District, where the pilot zone lies, has combined the pilot project with its work in renovation of old residential areas. By the end of this June, forty-three out of ninety-five projects have been finished. In Guangting Community of Tianshui Xiejia Area, nineteen old residential areas have undergone the “sponge plus” renovation. Except Sanhe Jiayuan Community and Yaojiang Garden Community, the “sponge plus” renovation mode also covers old residential areas like Guangsha Yiting Community, Chunhui Jiayuan Community, and Ningxinyuan Community.

Thanks to the “Sponge City” Project, many holes are now added to curbstones in the pilot zone, which connect curbstones and ecological trees, prevents rain drops to overflow, and purifies the water with the help of those trees; moreover, ecological means have been used to lead rain drops to green land to go through the seeping, retaining, storing, and filtering process, which supplies underground water and relieves the pressure of the city’s pipe network.
