"Such a conclusion had been reached by archaeologists long ago, since Kalibangan, for instance, shows no evidence of independent water supply; unlike Mohenjo- daro, it had very few wells, and unlike Dholavira, no reservoirs, yet it was continually occupied for several centuries: for its water supply through the year, it must therefore have depended on the Sarasvati, on whose left bank it lay, with entries into its fortified enclosures facing the riverbed."
