Providing solutions to water challenges in big cities
The world’s major urban areas face severe water-related challenges today and exponentially in the foreseeable future. Vulnerable communities disproportionately feel the effects. With a focus on the intersection of water and climate change, we will provide scalable solutions to water challenges in the world’s major urban areas, particularly in the developing world.

In the current state of climate crisis, cities face significant and increasing climate risks. The majority of these are due to changes in both our global and local water cycles. Whether it is too much water in the form of floods due to sea level rises, extreme precipitation and storms, or not enough water resulting in water shortages and droughts, no city in the world is immune to these climatic changes.
