English: "This indicator is measured as the ratio of the volume of wastewater treated before being discharged into the environment to the volume of wastewater being generated through particular activities.

Domestic wastewater refers to that generated by residential settlements, which is primarily generated through human metabolism and by household activities.

Industrial wastewater refers to that which is discharged after being used in, or produced by, industrial production processes, and is of no further immediate value to these processes.

Wastewater treatment involves physical, chemical or biological processes that remove solids, microorganisms and pollutants from water, to render it fit to meet environmental standards or quality norms for recycling or reuse.

The interactive visualizations show data for this indicator. The first chart shows the proportion of domestic wastewater that is safely treated and the second chart shows the proportion of industrial wastewater that is treated.

Target: “Halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally” by 2030.1"
