The paper argues that the concept and practice of sustainability have proved too difficult to achieve within traditional water management, and there is a lack of political will to move towards truly sustainable water services. Instead, compromised concepts, including resistance, resilience, ecosystem services, natural capital and adaptation are defining approaches; each of which may contribute partially to sustainability. Pressures due to the changing climate, ecological degradation, human demands, urbanization and deteriorating assets are challenging sustainability and compelling changes to water management. Water is now seen less as a problem to be managed than as an opportunity, as wherever situated, water brings many opportunities to contribute to anthropogenic needs. New ideas are helping to frame the way in which water management is being approached: (i) waste is no longer waste, but a potential resource within a circular economy; (ii) the interconnectedness of infrastructure systems and services and circularity of the water cycle mean there is a need to integrate approaches; (iii) nature-based systems should be preferenced for water infrastructure. These issues and ideas are considered here, together with examples of schemes showing that managing flooding can lead to wider benefits, and potential longer-term sustainability. This article is part of the theme issue 'Urban flood resilience'.
