The video says that they toke the water from springs under the pyramid. If the spring has enough pressure to make the water climb to 150 m, then just opening a vertical hole you must get a 150 m water jet. (Really, the water in the jet moves faster, so it has more internal frictions with the spring wall.) In Yellowstone, Old Faithfull has 50 m water jets, but it’s a geyser, not a cold spring with a lot of water.
