During all periods of human history collecting rainwater has been a useful way to get access to water. With ongoing climate change the guarantee of having water available is changing. With increasing heat the weather behaviour is shifting leading to more intense weather, both extremer rain periods and droughts. Due to this situation collecting rainwater is getting more attention. Rainwater can be used for various water needs depending on how much treatment it has been going through. With a local recirculation of rainwater the stress on water sources and demand against the waterworks can decrease. The aim of this master thesis was to develop a dimensioning tool, a recirculation map. A tool to quickly and easily analyse the potential of rainwater collection and rainwater reuse. With the flexibility to compare different scenarios, users can evaluate their options on rainwater collecting system. The recirculation map contains two parts. An interactive map that gives the user a quick way to get access to the rooftop surface area in which the collection of rainwater occurs. The other part is a dimensioning tool to quickly analyse the potential in collecting rainwater in relation to various water needs. Input parameters like rooftop area, runoff coefficient, rainwater demand per day and water magazine size were used for the dimensioning tool to analyse potential in collecting rainwater. The recirculation map ended up fulfilling all the demands and goals that were set at the beginning of the project.
