The high increase of industrial development, especially in new industrial zones, will lead to increase the water demand and consequently the wastewater discharge. Amriya district was selected as a case study of the new industrial zones in Alexandria. According to Alexandria Comprehensive Plan for the year 2017, the area will be served by the sewerage network and a treatment plant. The aim is to determine the quality of the wastewater discharged from some selected industries [twenty industries which represent different types of the industrial sectors and comparison will be made with law 93/1962 that govern the discharge of wastewater into public sewers. The physico-chemical results revealed that eleven industries are in compliance with the law and they can be connected directly with the future sewerage network. The other industries [nine industries] are not in compliance with the law and need pretreatment of their wastewater before connection into the public sewerage network. This study recommended some treatment methods for those industries to give a final treated effluent that is in compliance with the environmental laws.
