The city’s waterlogging problem must be the first issue reflected by the Zhengzhou flood. Zhengzhou government has invested 8.25 billion USD in the past 5 years to address the urban waterlogging problem. In 2016, Zhengzhou was selected as a provincial pilot site for the development of “Sponge City” in Henan Province.
Zhengzhou has invested a lot of human and financial resources in developing Sponge City. According to the Zhengzhou Evening News on May 29, since 2016, Zhengzhou has completed 5,162 kilometers of drainage network and the 50% utilization rate of recycled water. After implementing the Sponge City Development, Zhengzhou has eliminated 125 flood-prone sites in the city, with a 77% elimination rate.
Some people said: “Even if the contractors cut corners 10 times, as long as they follow the normal procedures to lay the foundation, the tree along the sidewalk will not grow directly to the ground. ” He also said that,” those new concepts of smart city and sponge city only sound fancy but useless.”
