Feasibility Study: Alexandria West Wastewater Treatment Plant Extension and Upgrade

The project “Feasibility Study for Alexandria West Wastewater Treatment Plant Extension and Upgrade” aims to expand capacity and upgrade treatment levels at Alexandria West Wastewater Treatment Plant (WWTP). Currently, the plant handles 340,000–410,000 m³/day, with a design capacity of 462,000 m³/day, but only provides primary treatment. It also receives untreated sludge from the East WWTP, discharging effluent into Lake Maryut, a heavily polluted environmental hotspot under the National Action Plan (NAP). 

Upgrading the treatment process will improve sanitation and environmental conditions in Alexandria and Lake Maryut, limiting waterborne diseases and enhancing economic opportunities. The project will provide a sustainable water source for agriculture and forestry, reducing pressure on scarce water resources. Biogas generation from sludge will cut WWTP energy costs and reduce its ecological footprint.

The project contributes to efficient water resource management and climate protection in Egypt by: 

  • Expanding WWTP capacity to 800,000 m³/day (serving 2.9 million people). 

  • Reusing treated effluent and digested sludge in agriculture and forestry. 

  • Lowering O&M costs through biogas utilisation. 

  • Minimising greenhouse gas emissions. 

  • Reducing pollution in Lake Maryut, El Mex Bay, and the Mediterranean.

Project Activities

Feasibility Study (FS) for the extension in both capacity and type of treatment of the Alexandria West Wastewater Treatment Plant (WWTP). More specifically, the technical, economic, financial, social and environmental feasibility of the following measures will need to be determined: 

  • Rehabilitation of the existing plant facilities where required. 

  • Increase of the design capacity of the WWTP. 

  • Upgrade of the current primary wastewater treatment to secondary wastewater treatment. 

  • Upgrade of the current sludge dewatering treatment to sludge digestion with energy generation.
