This strategic infrastructure project enhances Greater Cairo’s sanitation system by linking key
urban expansions to advanced sewage treatment at Gabal El Asfar. It supports New Cairo and
developments along Suez and Ring Roads. With a discharge of 550,000 m³/day, the system relies
on gravity-based reinforced concrete pipelines and extensive micro-tunneling over multiple
sectors to ensure efficient and sustainable wastewater management.
