Most of us in the development community are aware that proper water and sanitation services are crucial for life and health. Proper sanitation especially can decrease the instances and spread of disease. But in making the case to Ministers of Finance, it is often the economic and financial case that we have to make in order to garner the investments needed to make a difference.
A Water and Sanitation Program report we released last month, called Economic Impact of Sanitation in Indonesia (pdf), makes that case for that country. The report says that the economic costs of poor hygiene and sanitation in Indonesia reached an estimated US$6.3 billion, or 2.3 percent of GDP in 2006.
