Who built the first aqueduct?
Who built the first aqueduct? The first Roman aqueduct was built for the city of Roma by censor Appia Claudius Caecus, hence called Aqua Appia, and operational in 312 bc. Over 1000 Roman aqueducts are known today, built between 312 bc and the end of the Roman Empire (about 500 ad) and beyond. 2 Do we still have aqueducts today? Answer.
What were the aqueducts in ancient Rome?
Ancient Roman aqueducts were constructed to bring water from far away springs and mountains into cities and towns. The water would supply the city's fountains, gardens, public baths, latrines and houses of wealthy Romans (which had latrines and baths). The water from the aqueducts would also have agricultural and industrial uses.
How many aqueducts did Rome have?

Aqueducts in the Roman Empire. See also: List of aqueducts in the Roman Empire. Galería de los Espejos (Gallery of Mirrors), a tunnelled part of a 25 km Roman aqueduct built during the 1st century AD near Albarracín ( Spain) Hundreds of aqueducts were built throughout the Roman Empire.
How wide were Roman aqueducts?
Most Roman aqueducts were flat-bottomed, arch-section conduits, approximately 0.7m (2.3ft) wide and 1.5m (5ft) high internally, running 0.5 to 1 m beneath the ground surface, with inspection-and-access covers at regular intervals. Conduits above ground level were usually slab-topped. Early conduits were ashlar -built but from around the late Republican era, brick-faced concrete was often used instead. The concrete used for conduit linings was usually waterproof, with a very smooth finish. The flow of water depended on gravity alone. The volume of water transported within the conduit depended on the catchment hydrology – rainfall, absorption, and runoff – the cross section of the conduit, and its gradient; most conduits ran about two-thirds full. The conduit's cross section was also determined by maintenance requirements; workmen must be able to enter and access the whole, with minimal disruption to its fabric.
Why did the aqueducts fall?
Belisarius, defender of the city, had mills stationed on the Tiber instead, and blocked the conduits to prevent their use by the Ostrogoths as ways through the city defences. In time, some of the city's damaged aqueducts were partly restored, but the city's population was much reduced and impoverished. Most of the aqueducts gradually decayed for want of maintenance, creating swamps and marshes at their broken junctions. By the late medieval period, only the Aqua Virgo still gave a reliable supply to supplement Rome's general dependence on wells and rainwater cisterns. In the provinces, most aqueducts fell into disuse because of deteriorating Roman infrastructure and lack of maintenance, such as the Eifel aqueduct ( pictured right ). Observations made by the Spaniard Pedro Tafur, who visited Rome in 1436, reveal misunderstandings of the very nature of the Roman aqueducts:
Why was the Aqua Marcia aqueduct blocked?
The new aqueduct was intended supply water to the highest elevations of the city, including the Capitoline Hill.
Where did the water for the aqueduct come from?
Springs were by far the most common sources for aqueduct water; most of Rome's supply came from various springs in the Anio valley and its uplands. Spring-water was fed into a stone or concrete springhouse, then entered the aqueduct conduit. Scattered springs would require several branch conduits feeding into a main channel. Some systems drew water from open, purpose-built, dammed reservoirs, such as the two (still in use) that supplied the aqueduct at the provincial city of Emerita Augusta.
Why did the Romans build aqueducts?
The Romans constructed aqueducts throughout their Republic and later Empire, to bring water from outside sources into cities and towns. Aqueduct water supplied public baths, latrines, fountains, and private households; it also supported mining operations, milling, farms, and gardens. Aqueducts moved water through gravity alone, ...
What did the Romans use to make their water?
Before the development of aqueduct technology, Romans, like most of their contemporaries in the ancient world, relied on local water sources such as springs and streams, supplemented by groundwater from privately or publicly owned wells, and by seasonal rain-water drained from rooftops into storage jars and cisterns.
What is the Roman aqueduct?
The Roman aqueducts stand today, more than two thousand years later, as a testament to the engineering genius of the ancient Romans. These massive structures not only boggle the human mind as to how they were constructed but their function and reliability are still a modern marvel.
How many aqueducts were there in Rome?
There are eleven such aqueducts that supplied the ancient city of Rome, dating as early as 140 B.C. and spanning five hundred years.

Why were the aqueducts destroyed?
Towards the last days of the Roman Empire many of these Aqueducts were destroyed by invading German tribes as they sought to cut off Rome’s water supplies. The ducts were left in disrepair until the Renaissance when many were restored. At approximately the height of Rome’s population, 1 million inhabitants, the ducts provided up to 1 cubic meter ...
Why are the aqueducts visible above ground?
One of the reasons the Aqueducts are visible above ground is that the Romans were known for efficiently getting sources from one point to another in the least amount of time and distance. This helps explain the monumental archways and bridges of the Aqueducts we see traverse throughout the city.
How did the Roman water system work?
The entire system relied on various gradients and gravity to maintain a continuous flow. The water rushed from higher ground via the ducts and emptied into giant cisterns in the city. These cisterns then distributed the water through lead pipes which reached most of the city.

When was Aqua Anio Vetus built?
Aqua Anio Vetus was built in BC 272-269 and was a much more ambitious project than the previous Aqua Appia. At 260 meters above sea-level, this aqueduct tapped the Anio River east of Rome requiring a much longer system which was contained mostly underground.
Why was covering the aqueducts important?
Covering the aqueducts helped maintain water quality as the water slowly made its way downhill to Rome. Preventing animals, dirt, and other debris and substances from en tering the water system was important. Contaminated drinking water could spell trouble for Roman citizens who relied on the aqueducts for survival.
What system did the Romans use to supply water?
Introduction. Ancient Romans constructed complex hydrological systems known as aqueducts which supplied Rome with massive amounts of water through a complex system of open channels, tunnels, and pipes.
Why was the Aqua Claudia built?
The Claudia took 14 years to build and was built because of Rome’s growing size and demand for water.

How did aqueducts work?
Let us see how these aqueducts worked. The water in the aqueducts ran gently through concrete channels. Multi-tiered viaducts were developed by Roman engineers to cross low areas. Water from the aqueducts passed into large, covered catch-basins in designed to deposit their sediment.
When was the first aqueduct built in Rome?
The date of the first recorded aqueduct in Rome was in the year 312 B.C. From 312 BC to AD 226, 11 aqueducts were built to bring water to Rome from as far away as 57 miles. Aqua Appia, Aqua Nova, Aqua Alexandria and Aqua Virgo were some of them.
What materials were used to build the aqueducts?
The aqueducts were built from a combination of stone, brick, and cement made from volcanic materials called pozzuolana. The channels or waterways were built through rocks. The large water cisterns held the water for the city and they were connected to a large number of lead pipes.
Who was responsible for the construction of the Roman aqueducts?
Curator Aquarium was appointed to supervise it and workers and slaves were responsible for construction. Methods of construction of ancient Roman aqueducts have been described by Vitruvius of the first century BC in the book De Architectura. Many of the aqueducts of Rome are preserved and open to tourists today.
How many aqueducts did Rome have?
Rome had an incredibly complex system of aqueducts that brought water to the Empire’s Capital. There were 11 major aqueducts in total, and the Aqua Alexandrina was the final major aqueduct built in the city. Completed in 226 CE, water ran through the Aqua Alexandrina for more than 500 years until the 8th Century.
When was the first aqueduct built?
Without aqueducts, none of these luxuries would have been possible. With the first aqueduct completed in 312 BCE, the Romans expanded and improved on their designs over time, and created the many examples of Ancient Roman Aqueducts that we see today.
How does an Aqueduct Work?
The concept behind an aqueduct is extremely simple: because water will always flow downhill, by making a channel at a gradual decline the Romans were able to move water across great distances.
What was the name of the Roman aqueduct that rerouted water to the city of Tarraco?
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. Today along with several other important Roman sites, such as the city’s amphitheater, the Ancient Roman Aqueduct of Tarragona is listed as a UNESCO World Heritage Site.
What challenges did the Romans face when they built aqueducts?
The challenge comes when you have to make a consistently declining aqueduct over inconsistent terrain. So Roman engineers designed a system of tunnels whenever the aqueducts reached steep hills, and when the land dipped into valleys the Romans elevated the channels on top of arches. The elevated portions are the more famous and picturesque portions of Ancient Roman Aqueducts, although they made up only a portion of the overall construction.

What do you think of Roman aqueducts?
When you hear the words “Roman aqueduct,” do you think of lofty arches running to distant horizons? In fact, arches formed less than 20 percent of those conduits, the larger portion of which lay underground. This more economical design not only protected aqueducts against erosion but also minimized their impact on fields and neighborhoods. For example, the Aqua Marcia, completed in 140 B.C.E., was about 57 miles (92 km) long but comprised just 7 miles or so (11 km) of arches.
How many aqueducts were there in Rome?
Rome’s Urban Aqueducts. By the early third century C.E., 11 major aqueducts served the city of Rome. The first, the Aqua Appia, built in 312 B.C.E. and just over ten miles (16 km) long, ran almost entirely underground.

Originally, the Tiber River and nearby springs and wells provided sufficient water. From the fourth century B.C.E. on, however, Rome grew rapidly, as did its need for water.
How much water did the city's aqueducts carry?
How much water did the city’s aqueducts carry? A lot! The Aqua Marcia, mentioned earlier, daily channeled about 6.7 million cubic feet (190,000 cu m) of water into Rome. Once the water reached urban areas —gravity being the driving force— it flowed into distribution tanks and then into branches, which channeled the water to other distribution tanks or to locations for water use. Some estimate that Rome’s water distribution system grew to the point that it could have daily supplied more than 265 gallons (1,000 L) of water for each inhabitant.
How much water did the Aqua Marcia channel into Rome?
The Aqua Marcia, mentioned earlier, daily channeled about 6.7 million cubic feet (190,000 cu m) of water into Rome. Once the water reached urban areas—gravity being the driving force—it flowed into distribution tanks and then into branches, which channeled the water to other distribution tanks or to locations for water use.
How were aqueducts made accessible?
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. Rome’s Urban Aqueducts. By the early third century C.E., 11 major aqueducts served the city of Rome.
How long was the Aqua Marcia?
For example, the Aqua Marcia, completed in 140 B.C.E., was about 57 miles (92 km) long but comprised just 7 miles or so (11 km) of arches. Before building an aqueduct, engineers assessed the quality of a potential water source by examining the clarity, rate of flow, and taste of the water.
What did the Romans do with the aqueducts?
The aqueducts supplied the city and surrounding areas with water. Thanks to them, Romans installed fountains all around the city and helped many people in need. Let’s discover the top 10 facts about the roman aqueducts. 1.
What is the aqueduct called?
The aqueduct was then called “caput aquae”. In the end, they positioned pools or “limariae chambers” where the water was grossly purified. The conduction channel, made of stone or masonry, started from the same pool and arrived in the city.

What is the book of water?
The book of water: De Aquis Urbis Romae. You must know that there is an ancient book about the waters of Rome. The book called “De Aquis Urbis” by Sesto Giulio Frontino is a testimony of the situation in Rome. He tells us that until 312 BC the citizens were not satisfied.
Overview
Planning, surveying and management
The plans for any proposed aqueduct, public or private, had to be submitted to the scrutiny of civil authorities, who granted permission only if the proposal respected the water rights of other citizens. Inevitably, there would have been rancorous and interminable court cases between neighbours or local governments over competing claims to limited water supplies but on the whol…
Background
Before the development of aqueduct technology, Romans, like most of their contemporaries in the ancient world, relied on local water sources such as springs and streams, supplemented by groundwater from privately or publicly owned wells, and by seasonal rain-water drained from rooftops into storage jars and cisterns. Such localised sources for fresh water - especially wells - were in…
Uses
Rome's first aqueduct (312 BC) discharged at very low pressure and at a more-or-less constant rate in the city's main trading centre and cattle-market, probably into a low-level, cascaded series of troughs or basins; the upper for household use, the lower for watering the livestock traded there. Most Romans would have filled buckets and storage jars at the basins and carried the water to their apar…
Decline in use
During the fall of the Roman Empire, some aqueducts were deliberately cut by enemies. In 537, the Ostrogoths laid siege to Rome, and cut the aqueduct supply to the city, including the aqueduct-driven grist-mills of the Janiculum. Belisarius, defender of the city, had mills stationed on the Tiber instead, and blocked the conduits to prevent their use by the Ostrogoths as ways through the city defen…

Distribution
- Before the aqueducts, Rome depended on local sources such as the Tiber River and cisterns of collected rain water. Water quality, sanitation, and disease were daily problems Roman citizens were afflicted with. Droughts and drainage problems were deadly and as the population increased, so did the problem. The solution was the Civil Engineering marve...
Hydraulics
- Water is a heavy substance with adensity of 1,000 kilograms per cubic meter. With water flows ranging from 0.2 to 2.2 kilograms per second, there was a lot to consider when designing these hydraulic systems known as aqueducts. The water ran for the most part in open channels but siphons were used. A siphon is “a tube or conduit bent into legs of unequal lengths, for use in dr…
Water Quality
- Water quality was a problem in some of the aqueducts. Depending on the source of the water, debris and other finer materials would make the water unsuitable for drinking. Lakes and rivers that fed aqueducts were typically the sources of poor water quality, but rain could cause quality issues as well. Roman ingenuity came up with brilliant solution, settling tanks. Throughout the a…
Maintenance and Repair
- Maintenance was full time job in ancient Rome. A job requiring skill, aqueducts often failed due to soft building materials, erosion, and poor construction techniques. The Aqua Claudia was continually under repair due to breaches. Because of problems like this, access doors and diversion tunnels were used along with sluice gates and holding tanks to divert or store water w…
