As of 2008, more than a billion people lack safe water and 2.6 billion lacked access to sanitation worldwide. However, numerous technologies and approaches exist to provide access to clean water, sanitation, and hygiene (WASH). In this report from the Pacific Institute and the Woodrow Wilson Center’s Environmental Change and Security Program (ECSP), the authors evaluate 120 resources in the WASH sector and finds significant gaps. They recommend the development of a comprehensive decision-making tool to assist practitioners in evaluating and identifying the best technology or approach to meet their particular WASH needs.
