Present Status & Realistic Demand of China’s Low Impact Development Rainwater Control & Utilization Standardization

Abstract

With the progress of urbanization, the traditional rainwater flooding management is not applicable to the demand of new-type urban development, which causes the urban local flooding, water environmental pollution, water ecological non-recyclable and other issues. In recent years, with the pilot construction of the sponge city, the low impact development technology has been widely applied everywhere nationwide, while the state and local governments have actively developed and modified the relevant standards and specifications. Through teasing out the standards in the rainwater control & utilization and other relevant fields, this paper summarizes and analyzes the present status and realistic demand, so as to provide the reference for the next standardization construction of the sponge city.
