Only 1,000 million cubic metres of water are reused in Europe, a volume that could be multiplied sixfold.

Omissions

• The 1 billion m³ figure refers specifically to treated urban/municipal wastewater reused annually in the EU, not to total water consumption or abstraction.
• The sixfold figure is an estimated potential ('up to six times more'), not a realised or guaranteed increase; achieving it depends on investment, infrastructure and implementation of the EU Water Reuse Regulation.
