The Water, Sanitation, and Hygiene Sustainability Index Tool (WASH SIT) was developed through joint funding from Rotary International and USAID as part of the International H2O Alliance. The tool covers a range of quantitative and qualitative indicators grouped under the five main factors that influence the sustainability of services: 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 Liberia is to inform USAID WASH programming under the Agency’s Water and Development Strategy, particularly with respect to sustainability of water supply interventions.

While the SIT provides a sector-wide perspective, it does so through the lens of the interventions of a specific project in Liberia. The entry point for the application of the SIT is the USAID Improving Water, Sanitation, and Hygiene (iWASH) Program.
