Three examples of temporary stormwater catchments in dense urban areas: a sustainable development approach

摘要

The Seine Saint-Denis County Council carried out a study involving 200 water storage installations within its jurisdiction. The results showed that many of the basins were inadequate in such a dense urban area. The main problems were the following: difficulty of access, insufficient maintenance and poor integration into the urban landscape. To remedy the situation, the DEA launched research and information projects aiming to foster the development of techniques which would be better suited to dense urban areas, looking especially at catchments in parking lots, squares and other urban spaces. Three examples follow, illustrating the high potential of these techniques as well as the concrete or theoretical obstacles they may encounter. On a broader level, the examples demonstrate that these techniques are part and parcel of a "sustainable development" approach.
