WHITE PLAINS, N.Y. — Xylem pumps were chosen to be a key part of the solution in place to protect the ancient Sphinx and Pyramids in Giza, Egypt, from suffering water deterioration. When the Egyptian Antiquities Authority (EAA) determined that the groundwater levels at the Pyramids Plateau were too shallow and threatened the longevity of these ancient landmarks, action was needed to save the historical site. To solve the groundwater problems, the EAA and U.S. Agency for International Development created the Pyramids Plateau Groundwater Lowering Project.
The project plan outlined a solution for lowering and controlling the water table beneath the Pyramids Plateau and preventing erosion of the limestone that would preserve the pyramids for future generations to enjoy. The EAA, working with dewatering consultant and project designer AECOM, determined that lowering and controlling water levels in the aquifer below the pyramids would be best accomplished by drilling 18 water wells and installing high capacity stainless steel submersible turbine pumps.
Critical to the detailed planning was ensuring that the pumps would start when the water level reached a specific point in the aquifer. The pumps and related products chosen for this important job are made by Xylem, and they are now standing guard around the ancient site, removing groundwater when it rises too high and threatens the soft limestone structures.
EAA awarded the protection project to The Arab Contractors Dewatering Division (ACDD) located in Cairo, Egypt. The ACDD team drilled the wells and purchased and installed the required pumps and accessory equipment. Bids for the pumps and equipment were sent to companies specializing in water technology. Hydrotech was awarded the project based on providing the shortest lead-time, best product selection and overall financial package.
Hydrotech, in turn, evaluated the project and selected Xylem’s Goulds Water Technology submersible turbine pumps, motors and accessories as the best solution for the groundwater problem.
“Xylem’s Goulds Water Technology products were selected for this unique project because of their high quality, broad range, durability and energy efficiency,” said John Dimos, chairman at Hydrotech.
