Abstract: The performance of an urban drainage system is usually measured through the changes in the characteristics of the flood hydrograph in reference to a baseline. When designing and assessing the performance of Sustainable Urban Drainage Systems (SuDS), we must consider other impacts on the catchment, such as changes in the hydrological regime and contributions to the water supply system. The Urban Water Metabolism concept considers input, output and retained water flows in an intent to replicate the resource efficiency of a natural system (Renouf et al., 2018). The growing surface imperviousness and the centralization of water supply systems are one of the causes that make urban catchments metabolically-inefficient. SuDS impact directly on hydrological indicators and can enhance the efficiency of the urban water metabolism by replicating the capacity of recycling and adaptation of natural systems. This study quantifies indicators of the water metabolism of a small catchment in Brazil for an extreme event considering the implementation of SuDS.
