Much water body running in urban residential subdivisions in China is not successful, and deteriorated water and bad scenery happened frequently in rainy seasons. The main purpose of this study is to recommend a feasible water scenery planning program in urban residential subdivisions construction to improve water quality. Based on the detailed analyses, the main reasons of unsuccessful water running might lie in sustainable water resource shortage, improper water scale, water body structure, and subsequent weak self-purification ability. A feasible planning program was recommended, and a case design based on this program was presented. It is concluded that rainwater is a promising sustainable water resource to maintain water body. Such general planning as water scenery layout and scale, water balance analysis are main aspects in the water body construction design. If the results obtained in this study were extendedly applied, the water scenery in residential subdivision could be improved successfully.
