WASH-Flows

WASH-Flows is a Microsoft Excel-based tool developed under the Bolivia WATCH Program to bridge the gap between household-level WASH data and watershed-scale planning. It transforms qualitative household information into quantitative data to assess service vulnerability, estimate environmental contamination loads, and provide water demand and wastewater flow data for water resources management software. While developed for Bolivia and currently applied in the Tupiza, Pampa Huari, and Choqueyapu-La Paz watersheds, the tool is intended for use in low- and middle-income countries across rural and peri-urban settings.

• The WASH-Flows tool utilizes a Microsoft Excel interface to convert qualitative household data into quantitative analysis and graphical representations, allowing planners to assess the current state and vulnerability of WASH services at the community level.
• The tool is designed to support the achievement of Sustainable Development Goal (SDG) 6 by monitoring progress and prioritizing interventions in rural and peri-urban areas to ensure no one is left behind.
• WASH-Flows provides critical data for environmental and resource management, including estimates of contamination loads from inadequate sanitation and data on water demand and wastewater flows that can be integrated into watershed modelling tools like the Water Evaluation And Planning (WEAP) system.
• Developed under the Bolivia WATCH Program and financed by Sida, the tool has been applied in its beta version to three Bolivian watersheds: Tupiza, Pampa Huari, and Choqueyapu-La Paz.
