Bocage Urbain

Bocage Urbain is an ecosystemic, efficient and economic solution creating synergy between water, plants and human within the city. 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 flooding 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.

Implementation Stories

Bocage Urbain by VERTUO
Implemented by Icade in Aubervilliers (France) in 2020

Icade, a real estate developer, implemented a 102 m2 green corridor with Bocage Urbain® in Aubervilliers in 2020. This project, requiring a budget of 88,000€ (excluding VAT), has the capacity to store a ten-year rainfall over the entire street and allows irrigation of the park by infiltration into the soil. The solution is autonomous and can store 60 days of reserve in case of drought.


System has self-watered for past 2 years, even in times of hot and dry summers
