Data portal
GLAAS provides policy- and decision-makers at all levels with reliable, easily accessible, comprehensive data on water, sanitation and hygiene (WASH) systems, including on governance, monitoring, human resources and finance. GLAAS monitors elements of WASH systems that are required to sustain and extend WASH services and systems to all, and especially to the most vulnerable population groups.
The GLAAS 2025 report and Key findings have been launched!
The GLAAS 2025 report, State of systems for drinking-water, sanitation and hygiene: global update 2025, and Key Findings of the Report were launched on 26 January 2026 at the High-Level Preparatory Meeting for the 2026 UN Water Conference in Dakar, Senegal.

The report examines the status of key components of WASH systems: policy, plans, institutional arrangements and national targets; monitoring, review and use of data for decision-making; regulation and surveillance; human resources; and finance. The report provides an expanded analysis of the two SDG 6 means of implementation targets and indicators: (6.a) international cooperation and capacity-building support and (6.b) local participation. It also includes sections on development partner support and leaving no one behind as well as on WASH and climate.
