Integrated urban stormwater management: Evolution and multidisciplinary perspective
Résumé
This paper proposes an introductory review of the historical evolution of urban stormwater management, as well
as of current trends, challenges, and changes of paradigm. It reminds us first that most of the existing urban
stormwater infrastructures in developed cities are based on the modern urban sewer systems developed in the
second half of the 19th century in Europe. They have been built and for decades managed almost solely by urban
sanitation and water specialists, relatively independently of other technical services and, more generally, of other
stakeholders in cities. They contributed significantly to public health and fast conveyance of stormwater outside
the cities. However, at the turn of the 1970s, it became evident with increasing urbanisation that they also had
drawbacks: artificialisation of soils, reduction of aquifer recharge, pollution of surface water and ecological
impacts, etc. The paper indicates how new concepts and paradigms thereafter emerged to manage stormwater by
means of more sustainable and integrated approaches, aiming to solve the problems engendered by the previous
approaches. This integration embraces more and more disciplines and issues, far beyond the traditional field of
urban water engineers and specialists. The paper attempts to explain the need for this evolution, making urban
stormwater management more much complex, dealing and interacting with ecology, biodiversity, bioinspiration,
architecture, landscape and water values, citizens’ well-being, history, culture, and socio-economic aspects.
