The Cairo Sewage Project (Shenzo Aapy Axis) was a great project at a critical location in Cairo. The target of this project is to cross Shenzo Aapy Axis with 1200 mm HDPE pipeline Crossings with total length 2200 meters.

There were four crossings ( 850,550,470and 330 meters long), The challenge was  the length and diameter of the crossing, the bad soil condition ,  and working at a critical and main axis in Cairo.
