Youth around Bole Medhanealem area capitalise on the faulty drainage system, putting stones and collecting 10 Br to cross the other side of the road. Addis Abeba experiences rainfall in two seasons, with the major one occurring between June and September, constituting nearly 70pc of the annual rainfall of about 1,400mm. It has witnessed intense flooding on two notable occasions recorded in history: in 1978, claiming the lives of 12 people and destroying nearly 56 homes, and later in 1994, rendering 3,000 people homeless. These incidents were triggered by an overflow from the Little Akaki and Bantyiketu rivers.
