Desalination plants for hotels are becoming a key solution. The tourism sector continues to grow steadily, especially in Spain. Between January and July 2025 alone, the country received more than 55.5 million international tourists — a 4.1% increase compared to the same period of the previous year. 📈
This growth is taking place in a context where many tourist areas — especially coastal regions and islands — have limited water resources or face strong pressure during peak season. In these cases, water demand from hotels skyrockets.
Water independence: a strategic advantage
More and more hotel chains understand that securing their own water supply is a key decision. Having an independent source allows them to:
-
Ensure continued operations even during periods of stress on the municipal network.
-
Reduce reliance on external supply.
-
Increase resilience against climate variability or supply disruptions.
Seawater desalination plants using reverse osmosis are becoming a mature, efficient, and fully viable solution for hotels. They offer autonomy, savings, and high-quality potable water.
