Presenting target 6.3 on water quality and wastewater
What and why?
Target 6.3 sets out to improve ambient water quality, which is essential to protect both ecosystem health (target 6.6 and SDGs 14 and 15) and human health (recreational waters and drinking water sources, target 6.1), by eliminating, minimizing and significantly reducing different streams of pollution into water bodies. The main sources of pollution include wastewater from households, commercial establishments and industries (point sources), as well as runoff from urban and agricultural land (diffuse sources).
Progress towards target 6.3 at the global level will be monitored through two indicators:
- 6.3.1 Proportion of wastewater safely treated
- 6.3.2 Proportion of bodies of water with good ambient water quality
Examples of additional aspects that can help track progress towards target 6.3 include how much wastewater that is recycled and reused (also see indicator 6.4.1 on water use efficiency), agricultural practices to reduce pollution, solid waste management, as well as overall ecosystem health (also see indicator 6.6.1 on water related ecosystems)
