Untreated sewage 

Mathare is a place where most youths engage in Changaa. When we were passing by Nairobi river near Mathare slum, we had an opportunity to see how Changaa is made.
The whole process was taking place next to a river that is full of sewage and the sewage was the one that was used as a colant. they could use their bear hands to put and remove the pipes that were put in the sewage , which we as the members thought endangered their lives.
As we tried to enquire from them why they use the sewage, they replied it was the deepest colant they used
