Future water is already flowing through our cities

From the newsletter

As freshwater supplies come under growing pressure, African nations are looking beyond rivers, dams and aquifers to strengthen water security. Wastewater is increasingly viewed as a recoverable resource capable of supplying reclaimed water while generating energy, nutrients and industrial feedstocks for the circular economy. 

• Africa generates an estimated 28 billion cubic metres of wastewater annually, much of which is discharged with little or no treatment, representing a largely untapped resource. 

• The UN's latest SDG 6 report argues wastewater reuse and water efficiency must accelerate, positioning treated wastewater as an increasingly important pillar of future water security.
