Thanks to Richard Ashley for this report.

Arcadis: This report seeks to expand on our annual Sustainable Cities Index to focus solely on water and identify which city is harnessing its water assets for the greatest long term advantage. It is our hope that city leaders find this ranking to be a valuable tool in helping them to think of water as an opportunity and as a resource for economic development while also meeting the critical needs and safety of their residents and the environment.

The overall index examines the water sustainability of 50 cities from 31 countries across all continents of the world. Each of the cities included have distinctive water relationships that helped shape their urban character and define their commercial identity and competitiveness. The cities are ranked according to not only how sustainably they manage and maintain water, but also against their natural risk and vulnerability across three pillars of water sustainability – resiliency, efficiency and quality.   To find out more click here.
