Around 40 % of the population in Namibia's urban spaces have no access to improved sanitation facilities (MAWF 2009). It is however fair to assume that the situation in informal settlements is far more drastic. There is an acute need for action to improve the sanitary conditions. The Namibian Sanitation Strategy drawn up in 2009 aims to create awareness of sanitary infrastructure as a public commodity incorporating the aspects 'health promotion', 'environmental protection' and 'energy efficiency' (biogas), along with 'food production' (water re-use) (ibid). The rapid growth characterising many towns in the Global South should not be underestimated, even in a sparsely populated country such as Namibia. Outapi, a town in central northern Namibia, lies roughly 70 kilometres from the Angolan border and has 4,600 inhabitants (2010). However, according to the mayor of Outapi, the population is currently doubling in number roughly every 3 years.
