COVID-19 pandemic led to significant changes in domestic water use in many cities. One important question is whether and to what extent the pandemic stressed the resilience of the water supply system. Another question examined in the paper is whether changes in water use during confinement differed according to the sociospatial configuration of cities. We examine these questions in the context of a medium size city of Northern Spain characterized by a mix of residential land uses, and internal variations in education, age composition, and in- come, producing step gradients in water use. First, we select and analyze influencing factors in domestic water consumption. Second, using statistical regression tests, we assess whether or not and to what extent the same factors influenced consumption during the COVID 19 lockdown. Results indicate that COVID-19 related confinement increased work and study from home and reinforced WASH habits, leading to more water con- sumption. However, this increase was larger in medium and low-income neighborhoods than in high-income neighborhoods, showing the relevance of sociodemographic factors but also of other variables more relevant for outdoor water use such as precipitation. Despite this rise in consumption, the water supply system was able to withstand the shock caused by confinement showing a robust resilience both in physical and in social terms. However, more challenging scenarios such as the coincidence of a pandemic with a severe drought should be taken into account in future resilience development
