The USAID mission in the Democratic Republic of the Congo (DRC) is seeking innovative partnerships to enhance rural and peri-urban sanitation through the "Democratic Republic of the Congo (DRC) Rural and Peri-Urban Sanitation" cooperative agreement. This opportunity invites concept papers that propose transformative solutions to improve access to sanitation services and promote hygiene practices, including support for open defecation free (ODF) campaigns. The initiative emphasizes market-based approaches and collaboration with existing USAID-funded programs to ensure sustainable service delivery. Interested applicants must submit their concept notes, limited to five pages and written in English, by June 2, 2021, and can reach out to Kathlyn Bryant at kbryant@usaid.gov for further inquiries.
