Sanitation in ancient Rome, acquired from the Etruscans, was very advanced compared to other ancient cities and provided water supply and sanitation services to residents of Rome. Although there were many sewers, public latrines, baths and other sanitation infrastructure, disease was still rampant. The baths are known to symbolise the "great hygiene of Rome".
It is estimated that the first sewers of ancient Rome were built around 500 BC by the Romans, in imitation of the Etruscans. These early drainage systems were underground channels made to drain rainwater as it might wash away topsoil. Also, ditches were used to drain swamps such as the Pontine Marshes and subterranean channels were used to drain marshy channels. Drainage systems evolved slowly and began primarily as a means to drain marshes and storm runoff. The sewers were mainly for the removal of surface drainage and underground water. [1] The sewage system as a whole did not dramatically improve until the arrival of the Cloaca Maxima, an open channel that was later covered, and one of the best-known sanitation artifacts of the ancient world. Most sources believe it was built during the reign of the three Etruscan kings in the sixth century BC. This "greatest sewer" of Rome was originally built to drain the low-lying land around the Forum. Some scholars believe that there is not sufficient evidence to accurately determine the effectiveness of the Cloaca Maxima. However other scholars believe that one million pounds of human feces and water was transported through the Cloaca Maxima. [2] [3]
Alongside the development of the Cloaca Maxima, other sewers were built. Many of them linked to each other. A law was eventually passed to protect innocent bystanders from assault by wastes thrown into the street. The violator was forced to pay damages to whomever his waste hit, if that person sustained an injury. This law was enforced only in the daytime, it is presumed, because one then lacked the excuse of darkness for injuring another by careless waste disposal. During Agrippa's time as Aedile in 33 BC the Cloaca Maxima was largely reconstructed and renovated. [4] Strabo, a Greek author who lived from about 60 BC to AD 24, admired the ingenuity of the Romans in his Geographica , writing:
Around AD 100, direct connections of homes to sewers began, and the Romans completed most of the sewer system infrastructure. Sewers were laid throughout the city, serving public and some private latrines, and also served as dumping grounds for homes not directly connected to a sewer. It was mostly the wealthy whose homes were connected to the sewers, through outlets that ran under an extension of the latrine.
The Romans had a complex system of sewers covered by stones, much like modern sewers. Waste flushed from the latrines flowed through a central channel into the main sewage system and thence into a nearby river or stream. However, it was not uncommon for Romans to throw waste out of windows into the streets (at least according to Roman satirists). Despite this, Roman waste management is admired for its innovation.
A system of eleven Roman aqueducts provided the inhabitants of Rome with water of varying quality, the best being reserved for potable supplies. Poorer-quality water was used in public baths and in latrines. Latrine systems have been found in many places, such as Housesteads, a Roman fort on Hadrian's Wall, in Pompeii, Herculaneum, and elsewhere that flushed waste away with a stream of water.
The latrines (public toilets) are the best-preserved feature at Housesteads Roman Fort on Hadrian's Wall. The soldiers sat on wooden boards with holes, which covered one big trench. Water ran in a big ditch at the soldiers' feet.
In general, poorer residents used pots that they were supposed to empty into the sewer, or visited public latrines. Public latrines date back to the 2nd century BC. Whether intentionally or not, they became places to socialise. Long bench-like seats with keyhole-shaped openings cut in rows offered little privacy. Some latrines were free, for others small charges were made. [5]
According to Lord Amulree, the site where Julius Caesar was assassinated, the Hall of Curia in the Theatre of Pompey, was turned into a public latrine because of the dishonor it had witnessed. The sewer system, like a little stream or river, ran beneath it, carrying the waste away to the Cloaca Maxima.
The Romans recycled public bath waste water by using it as part of the flow that flushed the latrines. Terra cotta piping was used in the plumbing that carried waste water from homes. The Romans were the first to seal pipes in concrete to resist the high water pressures developed in siphons and elsewhere. Beginning around the 5th century BC, aediles, among their other functions, supervised the sanitary systems. They were also responsible for the efficiency of the drainage and sewage systems, the cleansing of the streets, prevention of foul smells, and general oversight of baths.
In the first century AD, the Roman sewage system was very efficient. In his Natural History, Pliny remarked that of all the things Romans had accomplished, the sewers were "the most noteworthy things of all".
The aqueducts provided the large volumes of water that—after serving drinking, bathing, and other needs—flushed through the sewers. A system of eleven aqueducts supplied the city with water from as far away as the Anio River. Anio Novus and Aqua Claudia were two of the biggest systems. The distribution system was carefully designed so that all waste water drained into the Cloaca Maxima.
The management and maintenance involved in keeping the aqueducts flowing is well described by Frontinus, a general appointed by the emperor Nerva as water commissioner toward the end of the first century AD. He described his work on the distribution system in De aquaeductu published at the end of the first century AD. When first appointed, he surveyed and mapped the entire system, and strove to investigate the many abuses of the water supply, such as the act of tapping into pipes illegally. He also systematized aqueduct maintenance with gangs of specially trained workmen. He also tried to separate the supply, so that the best-quality water went to drinking and cooking, while second-quality water flowed to the fountains, baths, and, finally, sewers.
The system in Rome was copied in all provincial towns and cities of the Roman Empire, and even down to villas that could afford the plumbing. Roman citizens came to expect high standards of hygiene, and the army was also well provided with latrines and bath houses, or thermae. Aqueducts were used everywhere in the empire not just to supply drinking water for private houses but to supply other needs such as irrigation, public fountains, and thermae. Indeed, many of the provincial aqueducts survive in working order to the present day, although modernized and updated. Of the eleven ancient aqueducts serving Rome, eight of them entered Rome close to each other on the Esquiline Hill. [6] Also, the first aqueduct was the Aqua Appia built in 312 BC by the censor Appius. [6] Other aqueducts of importance to Roman sanitation was the Aqua Marcia built between 144-140 BC, which provided large amounts of quality water to Rome. [7] One Aqueduct with some major importance to Rome was Traiana, which tapped from the clear springs of the northern and western slopes above lake Bracciano. [7] It is said that the “Romans fully appreciated the importance of plentiful and wholesome supply of water, for domestic purposes to health of the Community. [8] It was stated by Amulree that for 441 years after the building of Rome, it depended on water from the Tiber for drinking and other domestic purposes, but in 312 BC Appius Claudius Crassus provide Rome with water from the Springs of the Alban hills and brought to consumers by the means of Aqueducts. [8] The Amulree notes state that this practice is in line with the teachings of Hippocrates: that stagnant water should be refused, not the spring water from the hills or rain water. [8]
Roman rubbish was often left to collect in alleys between buildings in the poor districts of the city. It sometimes became so thick that stepping stones were needed. "Unfortunately its functions did not include house-to-house garbage collection, and this led to indiscriminate refuse dumping, even to the heedless tossing of trash from windows." [9] As a consequence, the street level in the city rose, as new buildings were constructed on top of rubble and rubbish.
Although there were many sewers, public latrines, baths and other sanitation infrastructure, disease was still rampant. Most dwellings were not connected to street drains or sewers. Some apartment buildings (insulae) might have had a latrine and a fountain on the ground floor. This didn't stop the residents on the upper floors from dumping their waste onto the street. There was no street cleaning service in Rome. Thus, the neighborhoods were plagued with disease. [10]
The baths are known to symbolise the "great hygiene of Rome". Doctors commonly prescribed their patients a bath. Consequently, the diseased and healthy sometimes bathed together. The sick generally preferred to visit the baths during the afternoon or night to avoid the healthy, but the baths were not constantly being cleaned. This means the healthy who bathe the next day might catch the disease from the sick who bathed the previous day. [10]
Latrines could be found in many places such as in baths, forts and the colosseum. The Romans wiped themselves after defecating with a sea sponge on a stick named tersorium. [11] This might be shared by all of those using the latrine, or people would bring their own sponge. To clean the sponge, they washed it in a bucket with water and salt or vinegar. [12] This became a breeding ground for bacteria, causing the spread of disease in the latrine. [10] It is commonly believed the Romans used sea sponges on a stick and dipped in vinegar after defecation (for anal hygiene), but the practice is only attested to once. [13]
There was widespread presence of several helminth types (intestinal worms) that caused dysentery. [14]
The Ancient Roman technology which impacted the water and sanitation system include:
Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids. Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.
Environmental engineering is a professional engineering discipline related to environmental science. It encompasses broad scientific topics like chemistry, biology, ecology, geology, hydraulics, hydrology, microbiology, and mathematics to create solutions that will protect and also improve the health of living organisms and improve the quality of the environment. Environmental engineering is a sub-discipline of civil engineering and chemical engineering. While on the part of civil engineering, the Environmental Engineering is focused mainly on Sanitary Engineering.
Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route. For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through adequate sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis, cholera, hepatitis, polio, schistosomiasis, and trachoma, to name just a few.
Sewerage is the infrastructure that conveys sewage or surface runoff using sewers. It encompasses components such as receiving drains, manholes, pumping stations, storm overflows, and screening chambers of the combined sewer or sanitary sewer. Sewerage ends at the entry to a sewage treatment plant or at the point of discharge into the environment. It is the system of pipes, chambers, manholes, etc. that conveys the sewage or storm water.
A flush toilet is a toilet that disposes of human waste by using the force of water to flush it through a drainpipe to another location for treatment, either nearby or at a communal facility, thus maintaining a separation between humans and their waste. Flush toilets can be designed for sitting or squatting, in the case of squat toilets. Most modern sewage treatment systems are also designed to process specially designed toilet paper. The opposite of a flush toilet is a dry toilet, which uses no water for flushing.
The Cloaca Maxima was one of the world's earliest sewage systems. Its name is related to that of Cloacina, a Roman goddess. Built during either the Roman Kingdom or early Roman Republic, it was constructed in Ancient Rome in order to drain local marshes and remove waste from the city. It carried effluent to the River Tiber, which ran beside the city. The sewer started at the Forum Augustum and ended at the Ponte Rotto and Ponte Palatino. It began as an open air canal, but it developed into a much larger sewer over the course of time. Agrippa renovated and reconstructed much of the sewer. This would not be the only development in the sewers. By the first century CE all eleven Roman aqueducts were connected to the sewer. After the Roman Empire fell the sewer still was used. By the 19th century, it became a tourist attraction. Some parts of the sewer are still used today. Whilst still being used, it was highly valued as a sacred symbol of Roman culture, and Roman engineering.
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.
The Shrine of Venus Cloacina — the "Shrine of Venus of the Sewer" — was a small sanctuary on the Roman Forum, honoring the divinity of the Cloaca Maxima, the spirit of the "Great Drain" or Sewer of Rome. Cloacina, the Etruscan goddess associated with the entrance to the sewer system, was later identified with the Roman goddess Venus for unknown reasons, according to Pliny the Elder.
The Baths of Agrippa was a structure of ancient Rome, Italy, built by Marcus Vipsanius Agrippa. It was the first of the great thermae constructed in the city, and also the first public bath.
De aquaeductu is a two-book official report given to the emperor Nerva or Trajan on the state of the aqueducts of Rome, and was written by Sextus Julius Frontinus at the end of the 1st century AD. It is also known as De Aquis or De Aqueductibus Urbis Romae. It is the earliest official report of an investigation made by a distinguished citizen on Roman engineering works to have survived. Frontinus had been appointed Water Commissioner by the emperor Nerva in AD 96.
A toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as blackwater and the combined effluent, including other sources, is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet.
The history of water supply and sanitation is one of a logistical challenge to provide clean water and sanitation systems since the dawn of civilization. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely.
The ancient Indus Valley Civilization in the Indian subcontinent was prominent in infrastructure, hydraulic engineering, and had many water supply and sanitation devices that are the first known examples of their kind.
The Romanization of Hispania is the process by which Roman or Latin culture was introduced into the Iberian Peninsula during the period of Roman rule.
A toilet god is a deity associated with latrines and toilets. Belief in toilet gods – a type of household deity – has been known from both modern and ancient cultures, ranging from Japan to ancient Rome. Such deities have been associated with health, well-being and fertility and have been propitiated in a wide variety of ways, including making offerings, invoking and appeasing them through prayers, meditating and carrying out ritual actions such as clearing one's throat before entering or even biting the latrine to transfer spiritual forces back to the god.
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term aqueduct is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term aqueduct also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Near East, and ancient Rome. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water.
During the imperial period of Rome, disease was a devastating aspect of life. As the borders of the empire continuously expanded and the population steadily grew, cities in the Roman Empire were exposed to a multitude of diseases. There were a variety of potential causes of these diseases present in the highly dense and quickly growing society's way of living. The sewage systems, the public bathing houses, and the diet of citizens in Imperial Rome all contributed to the spread of disease.
A urine-diverting dry toilet (UDDT) is a type of dry toilet with urine diversion that can be used to provide safe, affordable sanitation in a variety of contexts worldwide. The separate collection of feces and urine without any flush water has many advantages, such as odor-free operation and pathogen reduction by drying. While dried feces and urine harvested from UDDTs can be and routinely are used in agriculture, many UDDT installations do not apply any sort of recovery scheme. The UDDT is an example of a technology that can be used to achieve a sustainable sanitation system. This dry excreta management system is an alternative to pit latrines and flush toilets, especially where water is scarce, a connection to a sewer system and centralized wastewater treatment plant is not feasible or desired, fertilizer and soil conditioner are needed for agriculture, or groundwater pollution should be minimized.
The Cloaca Circi Maximi or Cloaca Circi was one of the three main sewers in ancient Rome. Alongside the Cloaca Maxima and Chiavicone dell'Olmo
