The Sanitation Crisis in Haiti

The world is experiencing an unprecedented sanitation crisis with more than half of the world’s population lacking access to a toilet that safely manages human waste. In Haiti, only 30% of the population has access to improved sanitation and less than 1% of wastes are safely treated, which has fueled one of the largest and most virulent cholera epidemics in recent global history.

While aquatic ecosystems become increasingly polluted with nutrients from human waste, the earth’s soil nutrients have been rapidly declining due to erosion and intensive agricultural practices, leading to a loss of biodiversity, extreme vulnerability to climate-related risks, reduced agricultural production, poverty, and malnutrition. As cities expand at staggering rates, it’s critical that the sanitation sector develops innovative approaches that work in dense urban areas to avoid exacerbating the toll of preventable waterborne disease.

Revolutionizing the Approach to Sanitation 

SOIL provides full-cycle sanitation services from containment to reuse by taking a circular economy approach that provides accountability across the entire sanitation chain.

By providing toilets and removing waste from communities, SOIL is preventing the spread of waterborne disease, increasing families’ safety and security, protecting vulnerable aquatic ecosystems, and providing critical livelihood opportunities.

SOIL then safely treats the collected waste and transforms it into compost which is sold to support agriculture, reforestation, and climate change mitigation efforts in Haiti.


Our Vision

Directly scale the sanitation service in Haiti to establish a global example for the sustainable provision of affordable, safe, and ecologically-friendly sanitation services.
