How Rome Drinks
Rome Runs on Water
It’s easy to take Rome’s water for granted. You fill your bottle at a nasone (a cast-iron fountain with an elegant curved spout), sip something cool and crisp, and keep it moving. No one stops to ponder an aqueduct. But maybe we should. That free, fresh flow of spring water is the culmination of more than two thousand years of engineering, empire, papal ambition, and a very Roman obsession with abundance.
Romans have always been a little water crazy. They weren’t in the market for the bare minimum. They wanted to flood their baths, top off their fountains, and animate gardens with cascades and jets. The city’s first aqueduct, the Aqua Appia, debuted in 312 BCE— mostly underground to both maintain a downward gradient for gravity feeding and to protect it from sabotage and stealing. But it was just the beginning. By the second century CE, the imperial capital boasted eleven major aqueducts stretching as far as sixty miles from their sources in the Apennines and beyond. Together, they delivered hundreds of thousands of gallons of water each day to the city’s homes, public baths, ornamental fountains, and vast leisure complexes. Some, like the Aqua Claudia, soared across the countryside on massive arcades; others tunneled silently beneath the hills.
Water, like food in Rome, had always doubled as both basic need and political tool. The curator aquarum, usually a high-ranking senator, oversaw distribution with bureaucratic zeal and military efficiency. Supply followed a strict hierarchy. Elite households and imperial properties had private pipelines (fistulae made of lead or terra-cotta) while the general population relied on public fountains and castellae (distribution tanks). But even those “public” water points reinforced the message: Water was a gift from those in power. Aqueducts were both plumbing and propaganda.
Then the empire collapsed, and so did the flow. Between invasions, neglect, and the repurposing of building materials (why quarry stone when you can just rip it off from an aqueduct?), Rome’s hydraulic system broke down. By the early Middle Ages, the city’s population had dropped from over a million to maybe twenty thousand. People drank from rainwater cisterns, shallow wells, or the Aqua Virgo, the lone flowing aqueduct that supplied the Field of Mars.
It wasn’t until the fifteenth century that the system began to recover. The Renaissance popes, eager to emulate and revive the grandeur of antiquity, realized they couldn’t anchor the capital of Christianity on muddy wells. So they brought back the aqueducts. Pope Nicholas V, the same humanist pope who founded the Vatican Library, jump-started the revival in 1453 by restoring the Aqua Virgo from its mere slow trickle. Originally built by Marcus Agrippa in 19 BCE to feed his baths near the Pantheon, the Aqua Virgo had survived—barely—through the Middle Ages. Nicholas turned it back on, and with it came a stream of Roman rebirth.
Over the next few centuries, each pope wanted his own splashy contribution. In 1586, Pope Sixtus V restored a branch of the Aqua Alexandrina and renamed it the Aqua Felice—after his given name, obviously. The fountain that celebrates the repair features a monumental Moses statue. Subtle. It brought water to the Quirinal Hill, then being redeveloped as a center of papal and aristocratic power. In 1612, Pope Paul V restored the Aqua Traiana and called it the Acqua Paola (again: after himself), culminating in the bombastic Fontanone that still rushes over the Janiculum with theatrical flair. These infrastructure upgrades were ideological monuments, liquid proof of papal dominance, architectural prowess, and access to divine abundance.
And then came the fountains. If ancient aqueducts were wonders of engineering, the fountains of Baroque Rome were feats of drama. The Trevi, built in the eighteenth century, is a marble riot of sea gods, horses, and roaring water. It may be the most famous, but it’s hardly alone. There are more than fifteen hundred fountains in Rome today, many with roots in restored ancient water sources.
By the time Italy unified in 1870 and Rome was declared the capital, the water system was again central to its identity. In 1874, the nasoni were introduced as part of a modern public health push. They’ve been flowing and growing in number ever since, dispensing free spring water across the city. Locals know the trick: Cover the spout’s bottom opening with your finger and a small arc of water spurts upward, letting you drink, no bottle needed.
Today, Rome still draws about 97 percent of its drinking water from natural springs in Lazio, including ancient sources like the Aqua Marcia. The Aqua Virgo feeds the Trevi. The Acqua Paola pours down the Janiculum. And the water, remarkably, still flows without chlorination; it’s filtered naturally through volcanic rock before it even reaches the city.
But the system isn’t flawless. Nearly 40 percent of the water is lost through leaks, thanks to aging infrastructure and decades of deferred maintenance. Climate change isn’t helping either. Hotter, drier summers and snowless winters put pressure on supplies and make Rome’s aqueduct network more vulnerable than ever. And yet, it endures: Fountains still gurgle, nasoni still drip under the umbrella pines, and deep underground, stone channels carved by hand two millennia ago still carry water into the heart of the city.
Egeria, The Spring That Time Forgot
To reach the Egeria Spring, head southeast from Rome’s historic center along the Appia Nuova, a modern road that echoes the ancient Via Appia Antica’s trajectory. Just past the built-up stretch of the Tuscolano district, turn onto Via dell’Almone and pull into the unassuming parking lot, where, on weekends, a small farmers’ market pops up with crates of seasonal produce and foraged greens. From there, descend the stone steps tucked behind a low wall. You’ll likely be following in the footsteps of locals clutching empty glass bottles or repurposed plastic jugs, ready to fill up on still or sparkling water for a nominal fee—only a few cents per liter.
This is the Fontana Egeria, a natural spring within the Caffarella Park, part of the Parco Regionale dell’Appia Antica. The spring feels like a secret, even if it’s hiding in plain sight. No grand Baroque sculptures, no tour groups. Just cool, mineral-rich water flowing from deep underground, as it has for thousands of years.
The name and myth of Egeria are rooted in Rome’s earliest days. She was no ordinary nymph; Egeria was a divine counselor, as well as the lover and adviser to Numa Pompilius, Rome’s purported second king and the architect of much of the city’s early religious life. According to legend, the pair would meet in the sacred groves near this very spring, where Egeria whispered the will of the gods into Numa’s ear. After his death, grief overwhelmed her, and she dissolved into tears, giving birth to the spring itself.
