This WASH-FIN Brief looks back at the experience of the USAID Sustainable Water and Sanitation in Africa (SUWASA) program in promoting access to commercial financing for water and sanitation in Kenya. SUWASA ran from 2010 to 2015, building on accomplishments of the Kenyan government in advancing sector reforms in the context of devolution and decentralization. This brief highlights the process, successes, and challenges of commercial financing for WASH and identies lessons for moving forward with continued commercial financing under the new USAID WASH-FIN program.
