Abstract [en]

In order to classify stormwater as a resource, rather than a problem, tools to emphasize added values generated by the stormwater system, are needed. In this study, the aim was to develop a method based on added values and risks for comparison and evaluation of stormwater systems.How added values are classified differs from case to case. The approach and the purpose of the analysis also affects the evaluation of added values. In this report added values are defined as:A value, for an individual, an organisation or the environment, other than the object's main intended purpose.In this report five different categories of risks and added values were studied, namely: environment, economy, technology, health and socioculture. In the analysis of added values the data collection was made in a questionnaire. A group was appointed the task to compile the answers and evaluate the outcome and identify the added values generated by the stormwater system. The risk assessment was conducted by estimating probabilities and consequences of a range of identified risk sources. The results were presented in a matrix.The methodology was tested in a case study where two stormwater systems were evaluated and compared to each other. One of the systems was a swale system and the other was a piped storm drainage system. The result showed no major differences with respect to added values, on the contrary, the risk assessment indicated some significant differences. The case study confirms that the developed and evaluated tool is applicable for this type of evaluation and comparison between different stormwater systems in diverse surroundings.The method, developed in this study can with advantage be used as a complementing tool when evaluating different stormwater system options.
