Trends in wastewater reuse in selected countries
Wastewater effluent reuse (before or after treatment) varies significantly within Africa and is influenced by a number of factors such as the area’s aridity; population’s proximity to the wastewater source; retrofitting versus new installations; quantity of reuse; pricing; source quality; public health; political will; public trust and knowledge; and regulations and guidelines for reuse in the particular country. In some countries, wastewater reuse is practised without much legal control.
The biggest challenges surrounding the acceptability of wastewater reuse are observed in North Africa.
South Africa’s Water Services Act of 1997 has no objection to the reuse of wastewater for various non-drinking water purposes. The country also has guidelines on wastewater sludge management (Herselman et al., 2008).
