The Economics of Sanitation Initiative (ESI) was launched in 2007 with a Water and Sanitation Program (WSP) study from East Asia, which found that the economic costs of poor sanitation and hygiene amounted to over US$9.2 billion a year (2005 prices) in Cambodia, Indonesia, Laos, the Philippines, and Vietnam. The groundbreaking study was the first of its kind to attribute dollar amounts to a country’s losses from poor sanitation. The report sparked public awareness and Government action in several countries. The ESI initiative was born as a response by WSP to address major gaps in evidence among developing countries on the economic impacts of sanitation. Following the success in East Asia, ESI studies were completed in Africa and South Asia, with a study currently underway in Latin America. ESI work continued at the global level through a WHO publication, Global costs and benefits of drinking-water supply and sanitation interventions to reach the MDG target and universal coverage, which found that the global economic return on sanitation spending is US$5.5 for every one dollar invested.
