BACKGROUND AND AIM: The current level of investment for water, sanitation and hygiene (WASH) in Africa remains totally inadequate to meet the sectoral needs of the countries resulting in the lowest service coverage and annual deaths of about one hundred forty-three thousand children. The supply of WASH is also threatened by other factors including water scarcity, rapid population growth, urbanization and industrialization. Over eighty percent of the countries have been unable to achieve their national WASH goal due to insufficient funds, The aim of the study is to assess the current financing mechanism and the regional disparities for WASH service delivery and identify evidence based intervention that will harmonize the role of the development partners. METHODS: A review of relevant literature, reports on WASH financing from government and external financing agencies, regional inter sectorial framework, country case studies. RESULTS:As African countries get started to meet the Sustainable Development goal, lack of adequate financial resources are being magnified. A water sector infrastructure and investment framework in South Africa found that only half of the required fund for WASH project is available for the next ten years. In the past less than one percent of lending was targeted to Sub-Saharan Africa. We find household expenditure and capital investment for sanitation far below compared to drinking water. New strategy for the sector financing should consider grants, loans, community cost sharing, and repayable finances from external support agencies. As part of this effort, accountability and cost reduction need to be prioritized while strengthening alliance with development partners. CONCLUSIONS:Much effort is needed by the countries to optimize the mobilization of all possible resources to direct solutions to the critical financial need to achieve the goal of universal access to WASH in Africa.
