Underground Water Table and Aquifer System

Beneath the Giza plateau lies a significant aquifer. Archaeologists have documented a complex system of water channels and shafts beneath and around the pyramids. The Osiris Shaft, discovered beneath the causeway of Khafre, descends 30meters through three levels to a water-filled chamber containing a granite sarcophagus on a small island. Geophysical surveys have detected voids and water-filled spaces beneath the plateau not yet excavated. Some researchers propose that flowing water beneath the pyramid was integral to its function — either for construction (hydraulic theory), energy generation (hydroelectric theory), or symbolic/spiritual purposes (primordial waters of Nun in Egyptian mythology).
