Sponge Cities: China’s $300 billion investment plan for green stormwater infrastructure

  • Soak up the rain... China has been on a path to create about 30 “sponge cities” to absorb, store and purify rainwater to deal with both floods and water shortages.
  • Ambitious plans... By 2030, China aims to have 80 percent of urban areas across the country behave like sponges.
  • Real money... The cumulative investment in sponge city projects could reach 1.9 trillion yuan [$300 billion USD] by the end of 2020.
