Barcelona is upgrading water treatment on the Besòs river, with officials planning to use the same model already applied on the Llobregat. The aim is to strengthen water supply across the metropolitan area and reduce reliance on rainfall and reservoir levels.
The move is part of a wider effort in Catalonia to make water management more resilient during drought periods. By adding treatment capacity on the Besòs, authorities want to diversify supply sources and ease pressure on traditional reserves.
The Llobregat system has already shown that treated river water can provide a steadier source when natural reserves are low. Extending that approach to the Besòs is intended to support a more stable network for Barcelona and nearby areas.
For readers following water policy in Catalonia, this is another sign of how local authorities are adapting infrastructure to changing climate conditions. The focus is on long-term supply security rather than short-term fixes.
