Maya plumbing, first pressurized water feature found in New World
Maya plumbing, first pressurized water feature found in New World
May 4, 2010

A water feature found in the Maya city of Palenque, Mexico, is the earliest known example of engineered water pressure in the new world, according to a collaboration between two Penn State researchers, an archaeologist and a hydrologist. How the Maya used the pressurized water is, however, still unknown.

"Water pressure systems were previously thought to have entered the New World with the arrival of the Spanish," the researchers said in a recent issue of the Journal of Archaeological Science. "Yet, archaeological data, seasonal climate conditions, geomorphic setting and simple hydraulic theory clearly show that the Maya of Palenque in Chiapas, Mexico, had empirical knowledge of closed channel water pressure predating the arrival of Europeans."

The feature, first identified in 1999 during a mapping survey of the area, while similar to the aqueducts that flow beneath the plazas of the city, was also unlike them. In 2006, an archaeologist returned to Palenque with a hydrologist to examine the unusual water feature. The area of Palenque was first occupied about the year 100 but grew to its largest during the Classic Maya period 250 to 600. The city was abandoned around 800.

"Under natural conditions it would have been difficult for the Maya to see examples of water pressure in their world," said Christopher Duffy, professor of civil and environmental engineering. "They were apparently using engineering without knowing the tools around it. This does look like a feature that controls nature."

Underground water features such as aqueducts are not unusual at Palenque. Because the Maya built the city in a constricted area in a break in an escarpment, inhabitants were unable to spread out. To make as much land available for living, the Maya at Palenque routed streams beneath plazas via aqueducts.
