Urbanization has been identified as one of the issues with the greatest environmental impacts on water resources. This study aims to make an environmental diagnosis of urban water management with a systematic approach in a basin with great hydrogeological complexity. We have analyzed urban water management in the Langueyú basin, Argentina, in the period comprehended between 1940 and 2015 in which the city has had a disordered urban growth. It showed that the lack of integrated management together with urban expansion have resulted in a process of building densification and infrastructure that favors the recurrence and magnitude of exceptional hydrological events. This has been accompanied by a spatial displacement of these events and a lack of sanitary services with the same sense of urbanization. It was also demonstrated that the lack of integrated water management this not only had consequences on the Tandil city services associated with the urban hydrological cycle, but also on the quality of its surface water resources (contamination of streams in its urban section) and groundwater (elevation of nitrates levels in water from wells water supply). The absence of a systemic approach to the problem has not considered the relationships between the subsystems involved in water management. This management has been based mainly on the application of structural measures. The main non-structural measure carried out has been to expand the regulations and some neighbor's struggle movements. Other non-structural measures promoted by several actors involved in urban water management, such as authorities, should be carried out in order to raise awareness amongst the population on the importance of water resource protection, especially in areas with hydrogeological limitations. Display omitted •Urban water management (UWM) is an organizing axis of space.•Urban water cycle includes different subsystems closely and complexly linked.•UWM should have a systemic approach that is necessary to address that complexity.•Structural measures only are not enough for a sustainable UWM.•Sustainable UWM requires non-structural measures with different stakeholders.
