The layout of the pipes ensures that essential services like drinking water would have a priority over things like fountains and public baths. The arches at the lowest portion are some of the largest the Romans ever built. Not only did it function as a regular aqueduct, it also doubled as a bridge that allowed people and vehicles to cross the Gardon River.
Its constant usage as a bridge lead to the preservation of the structure since the times of the Ancient Romans. Located in the heart of the historic center of the city, the Ancient Roman Aqueduct of Segovia is one of the best-preserved examples of Roman Architecture. The square surrounding the aqueduct is one of the most popular spots in Segovia, and the modern city has grown in harmony around the ancient structure. The aqueduct continued to function for more than 1, years, finally being decommissioned in the mid 19 th century.
Today the city invests in keeping the aqueduct intact and sponsors constant restoration projects. Les Ferreres Aqueduct was constructed during the reign of Augustus and supplied water to the city of Tarraco, modern-day Tarragona. The aqueduct rerouted water from the nearby Francoli River. Les Ferreres Aqueduct is regarded as one of the best preserved aqueducts from the Roman Empire.
The water channel is particularly well preserved, and in certain locations it still holds water during period of heavy rain. Due to the steepness of the valley the engineers had to build an aqueduct that was 89 feet 27 meters tall at its highest point. The total length of the system was 43 miles 69 km but most of that span is within an underground tunnel. The raised portion of the aqueduct was made with stone and a massive amount of Roman Concrete, which was maintained by the Romans for hundreds of years.
Eventually, when the Roman Empire was split into two halves, Constantinople, now modern-day Istanbul, became the capital in the east. Valens, who ruled the Eastern Roman Empire in the late 4th century CE , completed the construction of a large aqueduct that brought in water from natural springs to the west.

After the fall of the empire, the aqueduct eventually stopped bringing water to the city. However, these bridged structures made up only a small portion of the hundreds of kilometers of aqueducts throughout the empire. The capital in Rome alone had around 11 aqueduct systems supplying freshwater from sources as far as 92 km away 57 miles. Despite their age, some aqueducts still function and provide modern-day Rome with water.

Springs served as the most common sources for the aqueduct. However, some aqueducts got water from dammed reservoirs like the two still used in the provincial city of Emerita Augusta. Roman engineers used a number of different tools to plan the aqueduct's construction.
Horizons were checked using "chorobates," a flat-bedded wooden frame fitted with a water level. The aqueducts themselves ran 0.
While early aqueducts were made from ashlar, late Republic-era Rome used brick-faced concrete for a better seal. Contemporary Roman engineers such as Vitruvius recommended a low gradient of not less than 1 in for the channel. This was presumably to prevent damage to the structure. Once built, aqueducts had to be maintained and protected.
The city of Rome at one time employed about maintenance personnel for this purpose. The excellent planning of the ancient Romans ensured that maintenance requirements were incorporated into the design. For instance, underground sections of the aqueducts were made accessible by means of manholes and shafts. When major repairs were needed, engineers could temporarily divert the water away from a damaged section. The combined conduit length of the aqueducts in the city of Rome is estimated between to a little over miles.
That's a capacity of percent of the current water supply of the city of Bangalore, which has a population of 6 million — amazing! The city used it for centuries, and ruling governments maintained the aqueduct long after the Roman empire collapsed. They wielded unilateral control of their nation and could utilize slave labor to marshal grand projects.
In fact, that was part of the point. And yet aqueduct construction sometimes faced familiar hurdles. For example, in 19 B. C, the Roman general and legendary builder, Agrippa, was constructing a new aqueduct, the Aqua Virgo, which approached the city from the east. Agrippa was forced to divert the aqueduct to the north on a much longer course and negotiate a mix of public and private land use.
Construction of new aqueducts — and other projects — ultimately faded across the Roman empire in the centuries leading up to its collapse in A. And in the centuries that followed, the aqueducts would repeatedly fall into neglect and disrepair, only to be saved by last-ditch repair efforts that kept clean water flowing to the city of Rome.
In fact, the Aqua Virgo, the aqueduct that Agrippa so carefully orchestrated, still flows through the city today. Register or Log In. The Magazine Shop. Login Register Stay Curious Subscribe.
