The Reference of Singapore ABC Water Plan to China's Sponge City: A Case Study of Singapore Interlaced Building

Abstract

In order to solve the increasingly serious water environment problems in Chinese cities, the concept of sponge city in China is being gradually applied in the process of urban construction, and needs to be optimized in practice. ABC water project in Singapore integrates three elements (water gathering elements, water treatment elements, transportation and water storage elements) into the source, path and direction of rain flood management in line with the water management strategy in the overall storm flood management. The site development of ABC water project includes urban surface environment such as circulation facilities, structures, vegetation, waterways, water bodies and other water collecting elements. Water treatment elements and water collecting elements complement each other and can be used to slow down, hold up and purify the initial rainwater. Water transport and storage elements mainly refer to water facilities such as waterways and water bodies, covering Singapore rainwater management network. Due to the different urban planning parameters and space configuration, each site will have different planning strategies. This paper takes the Singapore intersecting building as an example to study the coordination and reference role of ABC water plan in sponge city, and thus provides some enlightenment for the construction of China's sponge city.
