Mr. George Muruka, Domain Leader, Private Sector Development at MicroSave discusses financial product development processes in scaling up sanitation finance in Tanzania. Recognizing the nexus between microfinance and access to water and sanitation services, he opines that limited public financing should naturally lead the water and sanitation sector to leverage on private sector funding. Microfinance including savings and credit services help households and/or SMEs to access WASH facilities and services. However, some pertinent questions linger: What is the business case for bankers? How can WASH NGOs engage the bankers more effectively? In this video, Mr Muruka, Sophie Tremolet and stakeholders in Tanzania present lessons from a one year action research project in Tanzania that engaged MFIs and sanitation NGOs to improve financing to households and businesses. Poor households have real financial need to construct appropriate toilets, connect to clean and safe water networks and reduce waterborne disease burden on household incomes.
