British Poet W. H. Auden once noted, “Thousands have lived without love, not one without water” (Auden, 1957). Water shortage has become an increasingly crucial crisis facing many cities around the world. The demand for water is rising constantly. Lack of access to safe water and adequate sanitation jeopardizes the lives of the urban poor (Zandaryaa, 2010). In such a situation, Rivers offer a great water source for many. The Nairobi River is a water source for the majority of the informal settlements where they use the water for both cooking and cleaning.
