Step-by-step methodology for monitoring wastewater treatment (6.3.1)

The Integrated Monitoring Guide provides a basis for national governments to monitor progress towards the new Sustainable Development Goal on water and sanitation (SDG 6). The Guide includes step-by-step methodologies outlining how countries can monitor each of the SDG 6 global indicators.

The methodologies have been designed to allow countries to monitoring SDG 6 at a level in line with their capacity and resource availability, and they promote harmonization and the use of international standards.

The step-by-step methodology for 6.3.1 explains how to monitor the proportion of wastewater safely treated, including definitions, computational steps, and recommendations on spatial and temporal resolutions.

WHO and UN-Habitat are the custodian agencies of indicator 6.3.1, and they have developed this methodology in a consultative process that included countries, international agencies and other experts.
