Colloque avec actes et comité de lecture. internationale. ; International audience ; New policy guidelines regarding the design and operation of urban drainage systems have brought several innovative systems in the Dutch municipalities for infiltration of storm water. Although the concepts of sustainable urban drainage systems (SUDS) are widely spread little knowledge was available for operation and maintenance of SUDS. RIONED foundation is the Dutch knowledge and information centre for urban drainage. RIONED contracted TAUW BV (Technical engineering and consultancy for water en environment) to conduct a field study monitoring the hydraulic and environmental behaviour of SUDS. In the municipalities of Enschede, Zwolle and Eindhoven several SUDS have been analysed in the past decade. Attention has been given to loss of infiltration capacity, accumulation of pollutants, efforts for and results of maintenance and the appreciation of the SUDS by the inhabitants. After ten years gathering data conclusions have been drawn and recommendations for design, constructing and maintenance are given in this article.
