The project aims to ensure a sustainable supply of drinking water for Greater Casablanca and the regions of Berrechid, Settat, and El Jadida, while alleviating pressure on water resources in the Oum Er-Rbia basin. The plant, spread over 50 hectares, will have a treatment capacity of 200 million m³ per year, expandable to 300 million per year by 2030, including 250 million dedicated to drinking water and 50 million to irrigation.
