Plumbing is also known to have been used in East Asia since the Qin and Han Dynasties of China. Sixty additional tile wells southwest of Beijing are also believed to have been built around 600 BC for drinking and irrigation. The well was caused by four rows of logs with a square frame attached to them at the top of the well. A well excavated at the Hemedu excavation site was believed to have been built during the Neolithic era. Archaeological evidence and old Chinese documents reveal that the prehistoric and ancient Chinese had the aptitude and skills for digging deep water wells for drinking water as early as 6000 to 7000 years ago. The Chinese text The Book of Changes, originally a divination text of the Western Zhou dynasty (1046–771 BC), contains an entry describing how the ancient Chinese maintained their wells and protected their sources of water. The Neolithic Chinese discovered and made extensive use of deep drilled groundwater for drinking. Some of the earliest evidence of water wells are located in China. Ancient East Asia Ancient China A Chinese ceramic model of a well with a water pulley system, excavated from a tomb of the Han Dynasty (202 BC – 220 AD) period 2400 BCE, Pyramid of Sahure, and adjoining temple complex at Abusir, was discovered to have a network of copper drainage pipes. Persian qanats and ab anbars have been used for water supply and cooling. The first sanitation systems within prehistoric Iran were built near the city of Zabol. See also: Qanat, Ab anbar, Shushtar Historical Hydraulic System, and Pillar of Gor In ancient Peru, the Nazca people employed a system of interconnected wells and an underground watercourse known as puquios. Bronze and early Iron Ages Ancient Americas Thereafter, wastewater was used for disposal, irrigation, and fertilization purposes by Hellenic civilizations and later by Romans in areas surrounding cities (e.g. Mesopotamian, Indus valley, and Minoan) since the Bronze Age (ca. Likewise, land application of domestic wastewater is an old and common practice, which has gone through different stages of development.ĭomestic wastewater was used for irrigation by prehistoric civilizations (e.g. Reuse of untreated municipal wastewater has been practiced for many centuries with the objective of diverting human waste outside of urban settlements. Waste water reuse is an ancient practice, which has been applied since the dawn of human history, and is connected to the development of sanitation provision. The size of human settlements was largely dependent on nearby available water.Ī primitive indoor, tree bark lined, two-channel, stone, fresh and wastewater system appears to have featured in the houses of Skara Brae, and the Barnhouse Settlement, from around 3000 BCE, along with a cell-like enclave in a number of houses, of Skara Brae, that it has been suggested may have functioned as an early indoor latrine. Wells dug around 8500 BCE, have been found on Cyprus, and 6500 BC in the Jezreel Valley. Prehistory Skara Brae, a Neolithic village in Orkney, Scotland with home furnishings including water-flushing toilets, 3180 BC–2500 BCĭuring the Neolithic era, humans dug the first permanent water wells, from where vessels could be filled and carried by hand. Furthermore, treatment processes to purify drinking water and to treat wastewater have been improved. Over the millennia, technology has dramatically increased the distances across which water can be relocated. Rivers would often serve as a crude form of natural sewage disposal. Early human habitations were often built next to water sources. a river or ocean, where it would be diluted and dissipated. The historical focus of sewage treatment was on the conveyance of raw sewage to a natural body of water, e.g. Throughout history, people have devised systems to make getting water into their communities and households and disposing of (and later also treating) wastewater more convenient. Major human settlements could initially develop only where fresh surface water was plentiful, such as near rivers or natural springs. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely.Īstronaut Jack Lousma taking a shower in space, 1974 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. Qanat in Kashan surfacing within the Fin Garden it is thought to have served Iran's Sialk area for thousands of years.
