ABSTRACT
This article describes the hydrologic conditions that resulted in the most severe drought ever experienced in Metropolitan São Paulo (2014–2015). The dramatic situation was tackled by structural and non-structural initiatives by water authorities to avoid social chaos in a region home to more than 21 million people. The article also considers the post-crisis scenario when, in 2018, the metropolis was hit by another serious drought. Due to more rational consumption, a better prepared water system and the start-up of two major water transfer structures, which added new contributions from nearby basins, the critical situation was not perceived by the population.
