Improving WASH Evidence-Based Decision-Making (IWED) is a program under Water for Africa through Leadership and Institutional Support (WALIS) that supports demand-driven initiatives identified by selected national WASH focal agencies in sub-Saharan Africa to foster better WASH policies, strategies, and decision-making.
The IWED Mozambique program worked with the National Directorate of Water Supply and Sanitation of Mozambique to create a National Water and Sanitation Information System (SINAS) to provide reliable, publicly available data on water and sanitation nationwide. SINAS is a web-based GIS system that houses detailed information and maps on water and sanitation access points throughout the country, which is collected using mobile data collection tools (tablets). The data- which are collected at the local level, validated at the regional level and stored in the national database- are being used by decision-makers to prepare and execute realistic plans for the development of water supply and sanitation infrastructure and services.
