Abstract:
Municipal water management has become increasingly complex due to aging infrastructure, climate change, increasing population, pollution and tight community budgets. Diverting storm water through sewer systems is common practice but is neither flexible nor provides additional ecosystem benefits. Therefore, the implementation of nature-based solutions such as green infrastructure has become a common urban drainage concept. The project “FlexAdapt” aims at evaluating stormwater management concepts from a technical, economic, environmental, and organizational point of view, to help small and medium sized communities choose the appropriate type of water management strategy. This thesis serves as a case study for FlexAdapt and executes a sensitivity analysis of the surface area of Wagram on the sewer system during heavy precipitation events. The method offers support for the geographic positioning of green infrastructure measures. An automated decoupling process was created to assess the impact of each catchment on the total and maximum discharge at the combined sewer overflow. A positive correlation was found between the sub-catchment size and both the total and maximum discharge. In the second part of this thesis the retention and infiltration capabilities of green infrastructure measures were assessed. This evaluation found that green infrastructure can realistically provide retention and infiltration capabilities comparable to the complete decoupling of a sub-catchment. Further detailed analyses are required to specify ideal green infrastructure parameters for a given catchment within a municipality.
