King Mohammed VI inaugurated the eastern coastal pollution control system in Greater Casablanca, built by Sogea-Satom. The system intercepts wastewater discharged between the port of Casablanca and the city of Mohammedia and channels it to the pretreatment plant at Sidi Bernoussi, which was also built by Sogea-Satom. The project involved 230,000 cu. metres of earthworks to a depth of 17 metres below sea level, 1,400 tonnes of reinforcement steel, 15,000 cu. metres of reinforced concrete and 4,700 sq. metres of roofing. It will better protect the population in the eastern part of Casablanca from the risk of pollution due to discharge of wastewater, notably from industry, into the sea.
