Chongqing's annual rainfall, the bulk of which falls in Summer and Autumn, is above 1,000mm. Due to the complex landscape, the city faces challenging considerations around flood control and drainage. As a typical mountainous area, Chongqing's ecosystem is sensitive, fragile and difficult to recover,coupled with climate, water, vegetation and man-made factors. As such, a normal underground pipe network cannot guarantee the city's safety from storm water. The challenge is one of making full use of the distinctive natural features, moving away from the traditional drainage-oriented rainwater treatment concept, and creating a soft system for urban drainage. This is a major hurdle Chongqing must overcome in order to build a sponge city.
The AQUADVANCED® urban drainage system, developed by SUEZ NWS, does realtime monitoring of the sewage and rainwater network system for water treatment enterprises and water management institutions, to mitigate flood risks and control the quality of water discharged to the natural environment.
The system has been successfully applied to 20 cities and regions, including Bordeaux, Paris, Marseille, Barcelona, and Singapore.
- The first phase of the project of Yuelai Sponge City Monitoring and Information Platform was completed and put into trial run in January 2018, spanning 18.67km2. It includes Yuelai Exhibition & Convention City, Yuelai Ecological City, and Yuelai Smart City. In the future, it will extend to the other areas of Liangjiang New Area.
- This project is of important significance to the successful construction of sponge city in Chongqing, and will have the first intelligent stormwater control system of China’s 30 sponge cities. This helps to establish the group's leading strategic position in the sponge city construction industry.
