Study On Performance Evaluation Of Rainwater Reuse Project In Nanjing Area

The sustained and healthy development of China's social and economic construction,to a great extent,provides a powerful impetus to the development of urbanization,and urbanization is also a necessary road to promote overall social progress.But we also found that with the rapid China urbanization,a series of city water system problems have gradually surfaced,become a hot topic,such as the frequent occurrence of city waterlogging,water environment deterioration,the shortage of water resource.Therefore,in the tide of China's economic construction,it is particularly important to adhere to the innovative road of urbanization and achieve sustainable development strategy.In eighteen big reports of the party has clearly put forward "in the face of severe resource constraints,serious situation of serious environmental pollution and ecosystem degradation,must establish respect for nature,comply with nature,protecting the natural ecological civilization,the ecological civilization construction in a prominent position".Therefore,the design and construction of a certain amount of natural accumulation function,has the natural penetration ability,good natural purification function of sponge city system construction is the construction of social economy especially is one of the important contents of the construction of ecological civilization must also is a major task in our city construction in the future.Urbanization is a powerful engine to maintain the sustained and healthy development of the economy,and also a necessary requirement to promote social progress in an all-round way.However,at the same time of rapid urbanization in China,a series of urban water problems inevitably appear,such as frequent waterlogging,deterioration of water environment and shortage of water resources.Therefore,we must innovate the road of urbanization and realize sustainable development.In eighteen big reports of the party put forward clearly "in the face of severe resource constraints,serious situation of serious environmental pollution and ecosystem degradation,must establish respect for nature,comply with nature,protecting the natural ecological civilization,the ecological civilization construction in a prominent position".To build a sponge city with natural accumulation,natural infiltration and natural purification is an important content of ecological civilization construction,and is also a major task for China's urban construction in the future.In the city to promote the sponge like a raging fire,from the central and local governments have attached great importance to administrative means,continue to launch,due to the lack of a clear performance appraisal standards,as investors lack professional knowledge,resulting in engineering design in the back of administrative compulsory requirements of the manufacture and use of rainwater,so that the final effect obviously uneven in quality.It is worth discussing,only in the performance management system to promote appropriate and accurate,generate economic benefits and comprehensive benefits to investors,in order to make the maximum effect of rainwater reuse.This paper aims at the preliminary data collection,reuse project related to rain in Nanjing area is analyzed,using the relevant theories of economics and mathematical modeling,attempting to organize and construct the performance evaluation system of Nanjing area rainwater may exist in the investors(owners)in compliance with government policy requirements at the same time,the implementation of social responsibility and,to recover the investment cost and profit.
