The Water Finance Coalition gathers national and international public development banks aiming to improve the financing of the water & sanitation sector in order to achieve Sustainable Development Goal 6, the Paris Agreement objectives and to enhance biodiversity protection.

Why finance water?

Climate change is water change.

The greatest risk of global warming relates to water and the pressure over quantity and quality of water resources is a threat to human lives and ecosystems. 2.1 billion people do not have access to safe water and 4.1 billion people are still deprived of safely managed sanitation.


This lack of service coverage and sustainable water resource management has dramatic consequences on health, gender equality, economy and environment. The COVID-19 pandemic is a brutal reminder of the need for such basic services.

The water and sanitation sector remains underfinanced, according to the World Bank, more than US$ 110 billion would be necessary every year to achieve the safe access to water and sanitation targets, but only one-third of the needs are actually covered.
