Día mundial del retrete 2018

World Toilet Day 2018

19th November

We celebrate World Toilet Day on the 19th November, declared by United Nations with the aim of raising public awareness of this issue. 

“When nature calls” is the theme chosen by United Nations this year.

The idea of waste is not present in nature: once the life cycle of resources is over, they are naturally recycled to keep the balance. Sometimes, it is enough to replicate these natural cycles to provide a solution to some of the most important sanitation problems around the world.

Sanitation solutions based on nature itself make the most of ecosystems by treating human waste before returning it to the environment. Most of these solutions are based on the protection and management of vegetation, soils and wetlands, including rivers and lakes.

Some of these solutions may be:

  • Latrines with a dunghill that collects and treats human waste inside the toilet, thus producing a free supply of fertilizers that can be used afterwards for farming.
  • Wetlands and reedbeds built my man that filter wastewater before it returns to rivers

Sanitary systems that work in harmony with the environment need to be developed. 

When nature calls, we need to listen to it and act.

892 million people
defecate in the open

1.8 billion people use a water source that may be polluted by feces

62,5% of the world population does not have access to improved sanitation

4.5 billion people live without a safe toilet


By means of a 3-phase-system it is possible to reduce the negative impact of feces on people and on the environment and to safely reuse them. For this reason, it is essential to build toilets and sanitation systems that work in harmony with natural ecosystems.

Conference “When nature calls”

When: 15th November at 7 pm

Where: Roca Barcelona Gallery

Participation: free 

Linked to the United Nations theme, the We Are Water Foundation organized the round table “When Nature Calls” where experts discussed and presented solutions based on nature to solve the water and sanitation situation. We were able to learn more about systems that allow communities to manage their waste with the available resources, producing a free supply of fertilizers to help farming, as well as options for filtering waste water before returning it to the water streams. In addition, together with Save the Children, Mujeres por África and the WAW Foundation itself, different case studies of projects implemented on site were presented, along with the processes followed to achieve them.
