The swimming pool is a facility that is colliding with the new climate regime. Many local authorities currently find themselves in a triple impasse (from the point of view of energy, ecology and budget) in the day-to-day management of their aquatic infrastructures. In this article, we look at some new experiments carried out by certain territories that start to think about the end of swimming pools as “exo-terrestrial” infrastructures, characteristic of urban and planning modernity. They invite us to think about an ecology of redirection based on a design of (good) closure and descalarity.
