Key Facts & Information

HISTORICAL BACKGROUND

• Before aqueduct technology was developed, Romans and others in the ancient world depended on local water sources like springs, streams, wells, and rainwater collected in cisterns.
• The Romans heavily utilized local supplies of freshwater, particularly wells, throughout their history. However, depending on water resources from a limited area hindered the city’s ability to expand and ensure its safety. 
• The Tiber River’s water was nearby, but it was contaminated with water-borne diseases. Rome’s aqueducts were not exclusively Roman creations, as their engineers were likely acquainted with the water-management techniques of Rome’s Etruscan and Greek allies. Nevertheless, the aqueducts were notably successful
• During the early Imperial age, the city’s aqueducts facilitated a population exceeding one million, and a lavish water supply for public facilities had become an essential aspect of Roman life.

AQUEDUCTS IN ROME

• By 226 CE, Rome had constructed 11 aqueducts, considered significant engineering accomplishments, to provide water for its large population. 
• Sextus Julius Frontinus, the Curator Aquarum for Rome under the reign of Nerva, recorded thorough statistics for the city’s aqueducts in 97 CE. Subsequent aqueducts constructed after Frontinus are less well-documented. 
• These estimations may have overlooked water loss. Contemporary engineers have doubted the accuracy of these numbers and assessed Anio Novus limestone deposits to calculate the average wetted perimeter and surface roughness equivalent to just 2/3 of the provided flow value.

Below is the list of aqueducts in Rome:

• Aqua Appia
• Aqua Anio Vetus
• Aqua Marcia
• Aqua Tepula
• Aqua Julia
• Aqua Virgo
• Aqua Alsietina
• Aqua Anio Novus
• Aqua Claudia
• Aqua Traiana
• Aqua Alexandrina

• By 312 BCE, the city’s need for water had likely surpassed its local resources, prompting the construction of the Aqua Appia aqueduct by the censor Appius Claudius Caecus. The Aqua Appia and a military road between Rome and Capua, known as the Appian Way, were two significant public undertakings at that period.
• Both initiatives held considerable strategic importance, given that the Third Samnite War had been ongoing for about thirty years at that time. The route facilitated quick troop movements, while most of the Aqua Appia was located within an underground conduit, providing a level of security from potential attacks.
• The water source was a spring located 16.4 km from Rome. It descended 10 m throughout its course and released over 75,500 m3 of water daily into a fountain at Rome’s cattle market, the Forum Boarium, one of the city’s lowest public areas.
• By 145 BCE, the city had once more exceeded its collective resources. An official commission discovered that the aqueduct conduits were deteriorating, leading to water loss due to leakage and unauthorized tapping.
• Quintus Marcius Rex, a praetor, renovated the aqueducts and added a third one called Aqua Marcia, which was considered a healthier water supply. This aqueduct was the longest in Rome and had enough elevation to provide water to the Capitoline Hill.
• Aqueduct construction projects in the city peaked during the Imperial Era, with the emperors taking over the task and credit for providing public water supplies from competitive Republican political leaders. During Augustus’ rule, the Aqua Virgo and the Aqua Alsietina were constructed.
• The latter provided Trastevere with significant amounts of non-drinkable water for its gardens and was utilized to construct an artificial lake for simulated naval battles to amuse the public. Another brief Augustan aqueduct provided additional water of exceptional quality to the Aqua Marcia.
• Rome’s aqueducts primarily sourced water from many springs in the valley and highlands of the Anio, which is the present-day river Aniene situated to the east of the Tiber River.
• The city was supplied by a sophisticated network of aqueduct junctions, tributary feeds, and distribution tanks. 
• Trastevere, located west of the Tiber River, was mostly supplied water by extensions of some of the city’s eastern aqueducts.
• These extensions were carried across the river using lead pipes buried under the roadbed of the bridges, creating an inverted siphon. 
• During scheduled repair and maintenance of the cross-river supply, the Aqua Alsietina’s contaminated waters were utilized to fill Trastevere’s public fountains. The issue was resolved when Emperor Trajan constructed the Aqua Traiana in 109 CE, delivering fresh water from aquifers near Lake Bracciano directly to Trastevere.
• By the end of the 3rd century CE, the city received water from eleven aqueducts subsidized by the state. The total length of its combined conduit is estimated to be between 780 and slightly over 800 km, with over 47 km (29 mi) elevated on masonry supports above ground level. 
• Rome’s water supply relied on four aqueducts: the Aqua Anio Vetus, the Aqua Marcia, the Aqua Claudia, and the Aqua Anio Novus.

USES OF AQUEDUCTS

CIVIC

• The initial aqueduct at Rome released water at a consistent rate and low pressure in the city’s primary commercial area and livestock market. 
• The water likely flowed into a tiered system of troughs or basins, with the upper ones for domestic purposes and the lower ones for watering the animals being traded. 
• Many Romans would have collected water in buckets and jars from the basins and transported it to their rooms; wealthier individuals would have assigned slaves to do the same job. 
• The outlet’s low elevation prevented it from providing a direct water supply to city households or buildings.
• Instead, the excess water flowed into Rome’s main sewer system, emptying into the Tiber River.
• The majority of residents still depended on well water and rainwater. Rome did not have public baths at that period. The first public baths in the city were likely constructed in the following century, inspired by earlier versions in the nearby region of Campania. Initially, a few private baths and small public baths on street corners may have had their own water sources.
• However, with the introduction of aqueduct water to higher areas of the city, larger and more luxurious public baths and fountains were constructed across the city. 
• Roman culture was characterized by the presence of public baths and fountains, which served as significant social hubs, with the baths playing a particularly important role.

FARMING

• Water was likely the most crucial factor in the agricultural economy of the Mediterranean region. Roman Italy had plentiful natural fresh-water supplies such as springs, streams, rivers, and lakes in certain areas, while they were totally lacking in others.
• The rainfall was erratic. Water was often in short supply during the hot, dry summer planting season. Farmers living near a public aqueduct were allowed a set amount of water for irrigation at a specific time by using a bucket inserted into the conduit through inspection hatches.
• This system aimed to prevent excessive water usage and ensure a fair distribution among users during scarcity.
• Throughout the growing season, a “modest local” irrigation system might require as much water as the city of Rome, and the cattle responsible for fertilizing the fields needed to be fed and watered continuously.
• Having licensed permission to use aqueduct water on farmland can result in enhanced production, generating revenue from selling excess food products, and appreciating the land’s worth. In rural areas, obtaining permits to extract aqueduct water for irrigation was very difficult. The use and misuse of these rights led to legal conflicts and court decisions. In 184 BCE, Cato attempted to restrict all unauthorized rural water sources, particularly those belonging to wealthy landowners.
• Illegal tapping could result in the confiscation of assets, such as the unlawfully irrigated land and its yield. However, this rule appears to have never been enforced and was likely unfeasible. Despite benefiting farmers, water thefts could lead to excess food production and lower food prices. Shortages of grain could potentially result in famine and social upheaval. 
• A practical solution must balance between the water requirements of urban populations and grain growers, tax the profits of the latter, and ensure an adequate supply of grain at a reasonable cost for the Roman poor and the army.
