Northern Haiti

Since building Haiti’s first EcoSan toilet in 2006, SOIL has gone on to build EcoSan toilets around northern Haiti. SOIL’s public EcoSan toilets are being managed by schools, community groups, tourism cooperatives and clinics in or around the northern Haiti communities of Cap-Haitien, Milot and Borgne.

Organizations or individuals wishing to build additional public toilets in these communities are welcome to contact SOIL about having the toilet wastes treated at SOIL’s compost site in Limonade (outside of Cap-Haitien).


Following the earthquake, SOIL expanded operations to Port-au-Prince and, with the support of Oxfam Great Britain, piloted a unique program to use ecological sanitation in emergency settings. After just a few months on the ground in Port-au-Prince, SOIL built over 200 public EcoSan toilets which provide sanitation services to over 20,000 people living at over 31 camps in the neighborhoods of Delmas, Tabarre, Petionville and Cite Soliel. SOIL is proud to say that our clean, effective and well-received EcoSan toilets in Port-au-Prince have been widely recognized as being some of the most well-functioning toilets in the city.

SOIL is now taking the lessons learned from this innovative new project in Port-au-Prince to create a sustainable ongoing sanitation solution for the greater metropolitan area.

What We Do / Compost

The majority of sanitation projects carried out in Haiti are implemented without forethought as to how the waste will be treated. Most toilets flush directly into rivers or the ocean and latrines are either abandoned when full or emptied untreated into sites that, again, leach directly into rivers or the ocean. SOIL is committed, not only to providing safe sanitation, but also to safely treating human waste through the process of composting.


According to World Health Organization standards, fecal pathogens are killed after one week at a sustained temperature of 122 degrees Fahrenheit. SOIL composts the human wastes collected from EcoSan toilets for six months to insure that the all pathogens have been killed and the organic matter has sufficiently broken down to be used for agricultural uses.


SOIL is currently transforming over 5,000 gallons of human excreta per week into rich compost critical for agriculture and reforestation efforts in Haiti.


SOIL has four waste treatment compost sites in Haiti. Learn More (button links to What We Do/Compost/Locations)
