The paper summarized the research progress and development trend for modern rainwater harvesting technology,pointed out that the modern rainwater harvesting technology is the result of combing the traditional rainwater harvesting technology with modern material,biology,computer simulation technology,modern water saving irrigation technology etc.

Applying the rainwater utilization technology in large-scale commonality construction has been laid store by people increasingly.

Analysis of urban rainwater utilization in Handan City;

The Application of Rainwater Utilization and Water Balance Analysis in Design of Waterscape for Urban Gardens and Residential Subdivisions;

Technologies and countermeasures of rainwater utilization in cities of China;

Study on the utilization of rainwater on urban municipal road pavement;

Based on the studies of the utilization of rainwater resources at home and abroad, the technology of rainwater utilization is investigated in this paper.

in Chinese rainfall utilization are firstly pointed out.

Urban rainfall utilization is proofed by practice a shortcut to mitigate those problems, and transforming the urban rainfall as resources is an inevitable tendency.

Thirdly, more attention should pain to rainfall utilization in development of water conservancy in r.

The rainwater utilizing measures and the treatment process of domestic sewage when the effluent is used to irrigate farmland are also studied.

Research the rainwater utilizing situation in the northern water city of Kaifeng,aims at supplementing the water source to ensure the urban water requirement,lessening the pollution of water resources,improving the standard of the prevention from the waterlogging inside the city.
