The central theme will be: “Seeing the invisible: the value of water”, and seeks to reflect on the problems of the lack of this precious liquid in many parts of the world.

In July 2010, the General Assembly of the United Nations (UN) recognized the right of all people to water and sanitation.

This means that each individual must have access to between 50 and 100 liters of the precious liquid per day for domestic use.

It must be safe, acceptable and affordable, its cost should not be more than three percent of household income, and the source should not be more than one kilometer from the home, nor should its collection take more than 30 minutes, the UN emphasizes.

In many countries around the world, hospitals do not have clean, running water, which causes serious problems, infections and many deaths related to this lack of hygiene.

The lack of water has a great impact on food production, energy, climate change, education and health.

According to several international organizations, it is estimated that four out of every 10 inhabitants of the planet are affected by water shortage.

Every year, 340,000 children under the age of five die from diarrheal diseases, and at least 1.8 billion people worldwide drink water that is not protected from contamination by feces.
