Discussion on rainwater utilization technique specification in Shenzhen City

The technological specification for rainwater utilization in Shenzhen City is discussed in this paper, which consists of definition, objective, different utilizing ways, and system setting. It is suggested that the objectives of rainwater utilization include peak flow decreasing, non-point source pollution control, and rainwater collection. The underlaying surface of Shenzhen could be divided into six kinds of different rainwater utilization area: mountainous region, building and residential area, urban village, commercial area, municipal roads and hotspot, and the water utilization methods for each area were introduced primarily. Finally, the methods and consideration employed in specifications about the water quality volume of non - point source pollution and rainwater collection volume were illustrated.
