Toward New Urban Hydrographies

The contribution to the book, entitled 'Towards New Urban 'Hydrographies'', is of a theoretical nature and is intended as a reflection on the hypothesis of the concept of 'new urban hydrography', which would consist of creating a rainwater collection system (from the private roof, via the backyard garden, the public pavement and the street) that always remains visible and is treated entirely on the surface. While we conclude this article by questioning the feasibility of such an idea - especially in terms of the division of private/public responsibilities and long-term management - the Brussels Region has shown itself to be particularly sensitive to these issues and has since developed a number of tools and strategies to promote the construction of new kinds of 'hydrographies'.
