The structure itself is built from a spine of tubes that carry water to and from the river. It utilizes three methods of water purification — first the tubes collect water from the river via capillary action and separate out the garbage, which is then used to create fertilizer. Second, water is filtered to eliminate dangerous contaminants and add beneficial minerals before being sent back to the river. Third, waste water from households is collected, processed and filtered and then added back into the river. Household waste is converted into fertilizer for use on the banks of the river and in the new ecosystem of the building.
