Spain is one of the most water-stressed countries in Europe — and yet it has built some of the most advanced management systems in the world. With over 80% of its territory at risk of drought, Spain had no choice but to innovate.
Today:
- Spain operates over 750 wastewater treatment plants for reuse, making it the leading country in Europe and the fourth worldwide in water reuse.
- More than 10% of treated wastewater is reused, compared to less than 3% in the EU average.
- The country has invested heavily in desalination plants, with Catalonia and the Mediterranean coast relying on desalinated water for up to 60% of supply in drought years.
This transformation turned Spain into a global model for resilience, efficiency, and circularity in water management.
The International Certificate in Management and Innovation for Water and Sanitation Utilities will immerse participants in this success story. Over five days, executives will explore Spain’s innovative models through lectures, case studies, and technical visits to leading projects.
👉 For leaders seeking practical solutions to water scarcity, Spain offers lessons that cannot be ignored.
