More than 465 million dirhams has been allocated for a major project to protect the city of Casablanca, particularly its eastern area, from flood risks. The project, known as the Eastern Reinforcement System (SRE), seeks to improve and strengthen the stormwater drainage network in a sustainable manner in an area experiencing rapid urban expansion, enabling it to cope with the effects of heavy rainfall.
Work on the project began in February and includes the construction of two underground stormwater storage tunnels with a combined capacity of nearly 45,000 cubic meters. The two tunnels will be built using modern excavation techniques designed to limit the impact of the work on traffic. Together, they will extend over a total length of 3.7 kilometers, with dimensions of 2.8 × 2.8 meters and 3.5 × 3.5 meters, connecting the existing “Al Quds” and “Hay Essadri” tunnels.
The project also includes the installation of 2.3 kilometers of collector pipelines, particularly along Sakia El Hamra Avenue, with diameters ranging from 1,000 to 2,000 millimeters, in addition to the construction of inspection chambers and drop structures, the installation of stormwater inlets, and the installation of a pumping system.
Work is currently progressing according to schedule, with the entire system expected to enter service during the second quarter of 2027.
Once completed, the “Eastern Reinforcement System” will help strengthen flood protection in Casablanca’s eastern area, particularly in the districts of Ain Chock, Ibn M’Sik, Sidi Othmane, and Sbata. It will also help improve the performance of the city’s stormwater drainage network.
The project is part of the “Priority Stormwater Drainage Program 2025-2030 ,” implemented by the Casablanca-Settat Regional Multi-Services Company to strengthen stormwater drainage infrastructure across the region. The program has a total budget of approximately 5.6 billion dirhams and includes the construction of six major stormwater collectors with a combined length of 90 kilometers and diameters of up to 6 meters.
The program is being implemented under the “National Integrated Sanitation and Treated Wastewater Reuse Program,” with joint financing from the Ministry of the Interior, the Ministry of Economy and Finance, the Ministry of Equipment and Water, the Casablanca-Settat Regional Council, and the Casablanca-Settat Regional Multi-Services Company.
