Control and reuse of the rainwater in the urban context

Within a correct and sustainable urban development, the control of the flows of rainwater to the ground is particularly important. When the balance of the rainwater at a territorial level is meaningfully altered because of the ground changes, implementations of infrastructures of water collection are often necessary and they are expensive from both the economic and the environmental and landscape point of view. It is evident, therefore, the necessity to check the process of water collection at the origin replacing or placing side by side to the traditional infrastructures the so-called "green infrastructures", as suggested by the United States Environmental Protection Agency. The aim of this research concerns the use of the principles of the nature as a model of management of the rainwater stimulating the hydrological potentialities not developed by the site. The final result consists in the individualization of "green" technologies both passive, only natural, and active with small engineering, allowing to carry out an urban micro-basin self-ruling the meteoric waters picked up to the ground in the area that is object of study according to the logic of "design for water conservation".
