In this article, the impact of rainfall variability on the Casablanca city sewage network is studied. The city is ranked as one of the most vulnerable coastal areas to floods risks due to rapid changes in urbanization, demography and also the change in the rainfall regime induced by climate change. The combination of these factors has increased the occurrence of floods, causing damage to urban infrastructure and significant economic losses.
