Egypt’s Sphinx, Pyramids threatened by groundwater, hydrologists warn

One month ago, Giza’s antiquities inspectorate installed a new system to pump subterranean water out from under Egypt’s historical Sphinx monument and the underlying bedrock.

Subterranean water levels at the Giza Plateau, especially the area under the valley temples and Sphinx, have recently increased due to a new drainage system installed in the neighbouring village of Nazlet Al-Seman and the irrigation techniques used to cultivate the nearby residential area of Hadaeq Al-Ahram.

The system involves 18 state-of-the-art water pumps capable of pumping 26,000 cubic metres of water daily.

The project, which cost some LE22 million and is financed by USAID, has raised fears among some hydrologists and ecologists that it could erode the bedrock under the Sphinx and lead to the historic monument’s collapse.
