Puquios
Summary
Puquios (from Quechua pukyu meaning source, spring, or water well) are ancient systems of subterranean aqueducts which allow water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. Puquios are found in the coastal deserts of southern Peru, especially in the Nazca region, and northern Chile. Forty-three puquios in the Nazca region were still in use in the early 21st century and relied upon to bring fresh water for irrigation and domestic use into desert settlements. The origin and dating of the Nazca puquios is disputed, although some archaeologists have estimated that their construction began about 500 CE by indigenous people of the Nazca culture.
The technology of the puquios is similar to that of the Qanats of Iran and other desert areas of Asia and Europe, including Spain. A few puquios in northern Chile and in other parts of Peru were probably constructed at the initiative of the Spanish after the conquest of the Inca Empire in the 16th century.
The puquios first became a subject of study in the early 20th century. Although they had been known before, historic evidence was scarce. Around 1900 scholars noted that puquios, locally known as socavones (lit. shafts), were spread through the oases of Atacama Desert. In the 21st century, puquios, in various states of use and decay, still exist in the valleys of Azapa and Sibaya and the oases of La Calera, Pica-Matilla and Puquio de Núñez. In 1918 geologist Juan Brüggen mentioned the existence of 23 socavones (shafts) in the Pica oasis, yet these have since been abandoned due to economic and social changes. The puquios of Pica-Matilla and Puquio Núñez tap the Pica Aquifer.
The puquios of the Nazca (or Nasca) region are of most interest to archaeologists as the area was the center of pre-Columbian civilizations such as Nazca culture which flourished from 100 BCE to 800 CE. Most archaeologists believe that the Nazca puquios are of pre-Columbian origin, but some believe that they were built by the indigenous subjects of the Spanish colonists in the 16th century.
