Comparison of faecal sludge and wastewater flows across African countries
Effluents from treatment plants and raw wastewater generated near water bodies such as rivers, lakes, oceans and seas are often discharged with or without treatment. Such practices pollute water bodies and increase risk to public health.
In the majority of cities in Africa, less than 30 per cent of the population is connected to sewers, largely relying instead on on-site sanitation facilities. When the facilities are full, some are left unemptied (i.e. ‘contained’) and abandoned. Only a small fraction of the emptied sludge is reported to be treated and safely discharged or used. A greater fraction is emptied and unsafely discharged into drainage channels, residential areas and receiving waters and onto land.
