Abstract

The influx of migrants to cities is placing a huge burden to infrastructure delivery in the Western Cape. This burden leads to the need for shelter and that in turn means that land is invaded illegally. The population now creates informal settlements. The rise of informal settlements leads to the lack of basic infrastructure such as water and sanitation. The environmental impact increases like pollution and that increases human health and gives rise to air-bone disease. As a result people tend to use open fields to defecate, illegal dumping, discharge of untreated waste water into wrong streams.

The full range of technical options for providing adequate basic sanitation is still not widely known nor are the characteristics of the different options well understood. In particular, there is little appreciation of the long-term financial, environmental and institutional implications of operating and maintaining the various sanitation systems. As a result, in many cases communities and local governments are choosing technical options that, in the long term, are unaffordable and/or unsustainable. Challenges arise from the wide range of options available and the differing environments and conditions to which each is suited. On-site sanitation is the main form of excreta disposal in most sub-Saharan African cities and will remain the most appropriate level of service for the urban poor in the medium term. Despite heavy public investment in sewerage systems in most primary and some secondary cities, typically only 10-15% of the urban population benefit from access to the sewer network. About 80% of the urban population depends on on-site facilities such as septic tanks and pit latrines which, unlike sewers, are usually the responsibility of households.
