In the vast Sudanese desert, freshwater become one of the most precious resources. Ironically, deep under the dry, hot surface is the largest underground lake in the world, which would change residents' lives dramatically if it were tapped.

Polish architecture firm H3AR imagines a solution: Buildings are inspired by both water towers and the native baobab tree, which would access the water through underground pumps. These towers would contain a water treatment plant, a hospital, a school and a food storage center.
