How Many Aqueducts Did Rome Have?

By Robert Palmer

Have you ever wondered how many aqueducts Rome had during its peak? Rome, known for its impressive engineering feats, was home to a vast network of aqueducts that supplied water to the city. In this article, we will explore the fascinating world of Roman aqueducts and discover just how many of these magnificent structures existed.

The Engineering Marvels of Ancient Rome

During ancient times, the Romans were renowned for their advanced engineering skills. They built grand structures, roads, and aqueducts that still awe us today. The aqueducts were one of their most significant achievements and played a crucial role in providing clean water to the citizens.

The Network of Roman Aqueducts

Rome had an extensive network of aqueducts that stretched across vast distances. These aqueducts were designed to transport water from distant sources to the city. The primary purpose was to provide drinking water and support various public baths, fountains, and private residences.

While it’s difficult to determine the exact number of aqueducts Rome had due to incomplete records and ruins, historians estimate that there were around eleven major aqueduct systems serving ancient Rome. Each system had multiple branches and channels.

1. Aqua Appia

The Aqua Appia was the first-ever Roman aqueduct constructed in 312 BC during the early Roman Republic. Its source was around ten miles east of Rome in the Alban Hills.

2. Anio Vetus

The Anio Vetus was built in 272 BC and relied on gravity flow from two sources: the river Aniene and diverted springs.

3. Aqua Marcia

Constructed in 144-140 BC by Quintus Marcius Rex, the Aqua Marcia was one of the most significant aqueducts. It had a length of over fifty-six miles and supplied water to the highest elevations in Rome.

4. Aqua Tepula

The Aqua Tepula, built in 126 BC, provided cool and clean water to the southern part of Rome.

5. Aqua Iulia

Commissioned by Augustus in 33 BC, the Aqua Iulia was designed to ensure a steady water supply to new residential developments on the right bank of the Tiber River.

6. Aqua Virgo

The Aqua Virgo is one of the few ancient Roman aqueducts still in use today. Built by Agrippa in 19 BC, it continues to supply water to some of Rome’s famous fountains like Trevi Fountain.

7. Aqua Alsietina

The Aqua Alsietina was constructed during Emperor Augustus’s reign and supplied water to his villa at Martignano Lake.

8. Aqua Claudia

The construction of the Aqua Claudia began under Caligula’s rule but was completed by Emperor Claudius in 52 AD. It was one of the longest aqueducts with a length of nearly forty-six miles.

9. Anio Novus

Built around 52 AD, the Anio Novus was considered one of Rome’s most impressive aqueducts due to its massive volume and flow rate.

10. Aqua Traiana

The Aqua Traiana was constructed by Emperor Trajan in 109 AD and utilized both underground tunnels and elevated channels.

The Legacy Lives On

The aqueducts of ancient Rome were a testament to the engineering prowess of the Romans. They revolutionized the way water was supplied to cities and laid the foundation for modern water systems. Although many aqueducts have deteriorated over time, their remnants continue to inspire awe and admiration.

The exact number of aqueducts in ancient Rome may remain a mystery, but their impact on the city’s development and culture is undeniable. These incredible structures stand as a testament to Roman ingenuity and are a reminder of the remarkable achievements of our ancestors.

Now that you know about some of the major aqueducts in Rome, take a moment to appreciate their significance and marvel at the engineering brilliance that shaped ancient Rome.
