• Four main force pipelines of 2.5 km in length and 600 mm diameter.
• One kilometre of micro tunnels of 600 mm diameter and one pipe of 1,300 m3/hr crossings of 2,900 mm diameter.
• The four pumping stations convey the sewage to the connecting chamber no. 2 on the main Greater Cairo Wastewater project.
