Sanitation and hygiene decisions are frequently based on infrastructure coverage, service indicators, or professional experience instead of direct assessment of fecal exposure and public health risk. Even basic monitoring data remain patchy: in 2025, only 70 countries, representing 48% of the global population, had estimates for basic sanitation services in health care facilities.
SaniPath, ComPASS, and WASH FIT turn field and laboratory data into maps and visual summaries that show decision-makers where risk is concentrated and which interventions matter most. In Senegal, PROMISE has strengthened municipal data systems. In Bangladesh, ITN-BUET brings experience institutionalizing sanitation data systems as a major training hub for WASH engineers. In Zambia, after finding limited routine use of formal decision-support tools, the team developed a framework with national and provincial stakeholders to embed them in government practice; the PROMISE External Advisory Board has highlighted it as a model other countries could adapt. In Uganda, evidence and approaches from PROMISE have been integrated into the 2026 Sanitation and Hygiene Policy and the National Environmental Health Strategy 2025–2030.
PROMISE partners have learned that cost, technical expertise, and complexity can limit routine use of these tools. Next steps include simplified workflows, interoperable data systems, dashboards, and decision-focused visualizations that keep scientific validity while being practical for government users, along with a PROMISE Knowledge Hub for sharing tools, training packages, and comparative evidence across countries.
