At a time when the climate emergency takes center stage on the global agenda, responsible water management has become a cornerstone of urban sustainability. Barcelona, as a committed city, promotes innovative solutions to ensure efficient water use, including recycling, reuse, and reducing water consumption in public spaces.
The exhibition “Aigua Km Zero / BCN”, organized by the Museu d’Història de Barcelona (MUHBA), offers insight into this environmental and civic commitment.
“Aigua Km Zero / BCN”: a must-visit exhibition
The exhibition takes place at Casa de l’Aigua in Trinitat Nova, a historic and restored site located in the Nou Barris district. Through visual, interactive, and educational resources, the exhibition explains how water is recycled in the city, its environmental benefits, and the role each citizen plays in this collective process.
From Hotel Arc La Rambla, you can easily reach it by public transport:
Take metro line 3 from Drassanes station, right next to the hotel, to Vall d’Hebron, then transfer to line 11 to Casa de l’Aigua.
Estimated travel time: around 30–35 minutes
