This paper discusses water security and wellbeing within a public health perspective and focuses on urban areas with high population density. It analyses access to safe water and the multiple challenges to water security in two megacities: São Paulo and London, comparing differences and similarities. It illustrates how water security and health are related to Agenda 2030 Sustainable Development Goal 6 (SDG6): universal and equitable access to safe drinking water, sanitation, and hygiene, and SDG3: healthy lives and well-being for all, focusing on the problem exacerbated by the context of the COVID-19 pandemic, during 2020
