How Many Reservoirs Were in Rome?

By Robert Palmer

Rome, the eternal city, is known for its rich history and architectural marvels. One of the lesser-known aspects of Rome’s infrastructure is its extensive network of reservoirs. These reservoirs played a crucial role in supplying water to the city, ensuring its survival and growth throughout the centuries.

The Ancient Roman Aqueducts

Before we delve into the number of reservoirs in Rome, it’s essential to understand the marvel that made them possible: the ancient Roman aqueducts. These impressive structures were engineering feats that transported water from distant sources to cities like Rome.

The aqueduct system consisted of a series of channels and tunnels built on arches to maintain a steady flow of water. The water would then reach the city through lead or clay pipes, filling public fountains and private homes alike.

The Importance of Reservoirs

While aqueducts supplied a constant flow of water, reservoirs were essential for storing and distributing it efficiently. They acted as buffers between the aqueduct system and the city, ensuring a stable supply even during maintenance or repairs.

Reservoirs also played a crucial role during periods of drought or when demand exceeded supply. By storing excess water during times of abundance, they provided a backup supply for times when natural resources were scarce.

The Countless Reservoirs in Rome

Rome boasted an impressive number of reservoirs throughout its history. While it’s challenging to pinpoint an exact count due to incomplete records and lost information, historians estimate that there were well over one hundred reservoirs scattered across the city.

Aquarium Alexandri

  • Location: Near Circus Maximus
  • Description: One of the oldest known reservoirs, it had a capacity of over 8 million gallons of water.

Reservoir of the Seven Springs

  • Location: Oppian Hill
  • Description: This reservoir collected water from seven springs and supplied the nearby Baths of Trajan.

Piscina Publica

  • Location: Esquiline Hill
  • Description: A massive reservoir that provided water to the surrounding neighborhoods and public baths.

The Legacy of Rome’s Reservoirs

The construction and maintenance of these reservoirs were no small feats. The Roman engineers displayed exceptional skill in designing structures that could store vast amounts of water while ensuring its proper distribution.

The legacy of Rome’s reservoirs can still be seen today. Many ancient reservoirs have been repurposed or transformed into archaeological sites, providing valuable insights into ancient Roman engineering and urban planning. These remnants serve as a reminder of Rome’s innovative approach to infrastructure and its ability to adapt to changing needs.

In conclusion, the number of reservoirs in Rome was substantial, with estimates surpassing one hundred. These structures were integral to the city’s survival, ensuring a steady supply of water through an intricate network of aqueducts and storage facilities. The legacy left behind by Rome’s reservoirs continues to inspire awe and admiration for the engineering prowess of ancient civilizations.
