Dholavira, India: A magnificent reminder of ancient civilisation
The Dholaviran people knew how to conserve water: tapping rain and perennial streams in great reservoirs, laying an underground sewerage system. In fact, Dholavira’s system of stone-faced channels and reservoirs — a must in the arid region — is the oldest in the world and used to store and distribute fresh rainwater or river water round the year.
Their society was stratified into three distinct classes of rulers, overseers and workers with their separate living and working areas, as is evident from the way the city is laid out, with a citadel, a walled middle town and a peripheral area probably for menuals.
