Improve water quality, wastewater
treatment & safe reuse
WHO – UN-HABITAT, 2018
• Water quality is worsening
• >80% of wastewater
discharged untreated
• Mineral fertilizers grew 10x (1960)
• Pesticide sales grew 35x
($ terms since1970)
• Livestock 3x (1970)
• Chemicals, medicines, hormones,
micro-plastics …

Increase water-use efficiency &
ensure freshwater supplies
Data sources: FAO AQUASTAT, 2016
• Water stress: 2bn people
& rising worldwide
• Irrigation is 70% of global water
withdrawals
• Advances in agricultural water
use efficiency key
• Also ‘non-conventional’ water,
i.e., recycled wastewater,
desalination, rainwater

Remove hazards from the environment
Return resources - water, nutrients
and energy – to productive uses
• Groundwater recharge
• Industrial & landscape water
• Salt-water intrusion barrier wells
• Fertilizer pellets from sludge
• Energy from biogas

Summary
• We are not on track to meet SDG 6
• If we fail SDG 6, we will struggle with all SDGs
• Ambitious targets require ambitious solutions
• We must be ambitious
• We are the water managers, engineers, scientists
and citizens who must Shape our Water Future
