SOIL is a non-profit research and development organization working in Haiti to design, test and implement social business models to increase access to full-cycle household sanitation services in vulnerable urban communities. Over the last 10 years, SOIL has pioneered approaches to sustainable sanitation service delivery that combine innovative service delivery models and new technologies with a strategic, catalytic approach to financial sustainability. SOIL's flagship programme, EkoLakay, provides household-level ecological sanitation to families in vulnerable urban communities in Haiti. EkoLakay is a monthly toilet rental service: clients pay a small monthly fee and receive a toilet and weekly waste collection services.
