WASH-Flows

The WASH-Flows tool, developed by the Stockholm Environment Institute under the Bolivia WATCH Program, is a Microsoft Excel-based analytical tool designed to estimate and assess the vulnerability of water, sanitation, and hygiene (WASH) services at household and community levels. It aims to integrate WASH data into watershed planning and support progress toward Sustainable Development Goal (SDG) 6, particularly in rural and peri-urban settings in low- and middle-income countries.

• WASH-Flows is an analytical tool that uses a Microsoft Excel interface to convert qualitative household and community data into quantitative analysis and graphical representations to assess the vulnerability and status of WASH services.
• The tool's primary objectives include assessing progress toward national and SDG 6 goals, estimating environmental contamination loads from inadequate sanitation, and providing water demand and wastewater flow data for use in water resources management software like the Water Evaluation And Planning (WEAP) system.
• Developed following the "service ladders" methodology from the Joint Monitoring Programme (UNICEF & WHO), the tool was created under the Bolivia WATCH (WASH Thinking Connected to Hydrology) Program and funded by the Swedish International Development Cooperation Agency (Sida).
• The tool is currently in a beta version and has been applied in three Bolivian watersheds: Tupiza, Pampa Huari, and Choqueyapu-La Paz. There is reported interest in its application in Spain, Colombia, Perú, México, and Guatemala, with trainings already conducted for government agencies in Guatemala and various stakeholders in Bolivia between August and September 2023.
