Main ideaMain idea Implementation of dry latrines to provide
the surrounding communities of lake Atitlán - in the developing process - of decent and efficient services that also contribute to clean the villages and natural wealth.
The eco latrine model doesn’t use water and substitutes the cesspool (highly polluted) with containers that decompose the solid excretes making them less contaminant or, in the best of cases, takes advantage and uses them as a fertilizer.
