Discovery
An ancient Maya palace in Palenque, Mexico, had a
pressurized water system that could have powered
residential wastewater disposal ... or a fountain.

The New World’s earliest known example of engineered water pressure was discovered by two Penn State archaeologists in the Maya city of Palenque, Mexico.

“Water pressure systems were previously thought to have entered the New World with the arrival of the Spanish,” the researchers wrote in a recent issue of the Journal of Archaeological Science. But this water feature predates the arrival of Europeans.

The city of Palenque was built around the year 100 in a constricted area with little land to build on and spread out to. By the time the city’s population hit its zenith during the Classic Maya period from 250-600, the Maya had saved precious urban space by routing streams beneath plazas using aqueductlike structures.

The pressurized water feature is called Piedras Bolas Aqueduct, a spring-fed channel on steep terrain.

From the tunnel’s entrance to its outlet 200 feet downhill, the elevation drops about 20 feet and its diameter decreases from 10 feet near the spring to about a half a foot where the water emerges.

This combination of a downhill flow and sudden channel restriction pressurized the water, shooting it from the opening to an estimated height of 20 feet.

2. It amazes me what the ancients were able to accomplish

without the technology we have today. To accomplish some of their feats, these people must have been so far advanced. We think we're the bee's knees. Think about all the accomplishments made by citizens of the earth between BC an AD.

I find it remarkable. Just travel to some of the ancient sights and see what was done before we all were a gleam in anyones eye. Truly amazing.

3. The Minoans (3000 BC- 1500 BC) had indoor plumbing too....

on the island of Crete.
