Percentage of wastewater safely treated , disaggregated by economic activity
This indicator is proposed as an indicator for Sustainable Development Target 06.3 By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally.
Existing data are available from WHO/UNICEF JMP, FAO-QUASTAT, IBNET and UN-Water GLAAS, as well as population density data, and land-use/ landcover data from earth observations. New data will come from a variety of sources combining utility and regulator data for off-site systems and potentially household surveys and measured data for onsite systems, supplemented by modelled estimates where no reliable national data exist. Modelled estimates can be generated using JMP data combined with
treatment performance in different population density and income settings
WHO and UN-Habitat, on behalf of UNWater. Under the UN-Water umbrella, a partial monitoring framework is already in place, currently being finalized under the inter-agency monitoring initiative known as GEMI (Integrated Monitoring of Water and Sanitation Related Targets). GEMI is a new coherent monitoring framework, working closely with JMP), an autonomous programme affiliated with UN-Water, to ensure long-term monitoring for the entire SDG 6. The GEMI monitoring initiative in collaboration with WHO/UNICEF JMP will provide baseline estimates for safe management of faecal wastes. Through combined data sources, data is available for at least 85 countries. Less data are available for onsite and industrial.
