The Water Was Free

At the empire's peak, Rome's aqueducts delivered roughly 1 million cubic meters of water per day to a city of about a million people — close to 1,000 liters per person, far more than most modern cities use today. And the water was free at public fountains, available to anyone regardless of status.

This was not charity. It was political infrastructure. A guaranteed water supply prevented riots, enabled hygiene, and fed the huge bath complexes where political deals were struck. Emperors who built aqueducts got their names inscribed for a thousand years. Those who let the aqueducts crumble got overthrown. Water was politics in stone.
