Bocage Urbain

About

Whereas rainwater is usually seen as waste, this urban grove proposes an innovative management of rainwater by plants ; complementary to the existing solutions in the urban landscape: green roofs, valley gutters, retention basins, wells... The Bocage Urbain storage structure takes the form of prefabricated cubes combining a rainwater retention basin and a tank of plants specifically designed to maximize evapotranspiration. Its structures are installed : on the linear tracks, buried in the ground, to collect runoff water or at the foot of a building connected to the gutters to collect roof water. As the grove storage facilities are modular, they connect with each other in order to build a planted hydraulic network element replacing or supplementing mains drainage of cities. Also, urban grove answers to 5 fundamental issues of the city, it: reduces probability of floodings during heavy rains ; fights against urban heat islands ; helps vegetalization of the public space without the watering constraint ; improves urban air quality ; enhance biodiversity development in the city through the creation of green frames. Bocage Urbain also avoids water treatment systems (and maintenance) in urban projects and let the nature manage constraints.
