SDG #6 is to “Ensure availability and sustainable management of water and sanitation for all”
Within SDG #6 are 8 targets, of which we here focus on Target 6.3:
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
Target 6.3 has two indicators:
Indicator 6.3.1: Proportion of domestic and industrial wastewater flows safely treated
Indicator 6.3.2: Proportion of bodies of water with good ambient water quality
The proportion of treated domestic wastewater worldwide stands at 57% as of 2022. Very few countries have enough data to report treatment for industrial wastewater.
The global proportion of water bodies with good water quality stands at 71% as of 2020.
