The Water, Sanitation, and Hygiene (WASH) Sustainability Index Tool (SIT) is designed to assess a range of quantitative and qualitative indicators grouped around five main factors that influence the sustainability of services. These are institutional, management, financial, technical, and environmental. The SIT utilizes data collected from multiple sources, recognizing that factors for sustainability include practices at the household and service provider levels, as well as the enabling environment at the sub-national and national levels. 

The overall purpose of the WASH SIT assessment in Ethiopia is to inform the United States Agency for International Development (USAID) WASH programming, particularly about sustainability of interventions. It is also intended to inform broader sector dialogue and policy development in the country. While the SIT provides a sector-wide perspective, it does so through the lens of a specific project’s interventions. In Ethiopia, the entry point for the application of the SIT is the Your Health in Your Hands (YHYH) project implemented by Save the Children (STC) between 2009 and 2013.

This project worked in four regions of Ethiopia and in 46 woredas. Following consultations with both USAID and STC staff, the SIT was designed to focus on four intervention types: community-led total sanitation and hygiene (CLTSH); community handpumps (CHPs); institutional sanitation in schools (INS); and springs with on-spot distribution systems (SPO). Data collection for the SIT occurred in 12 of the 46 woredas across the four target regions (Amhara, Oromia, SNNPR, and Tigray) and focused on 75 unique interventions. It included 1,080 household surveys at the kebele level and 137 key informant interviews with service providers.
