In South Africa, the main driver for wastewater reuse is drought conditions. [18] For example, in Beaufort West, South Africa's a direct wastewater reclamation plant (WRP) for the production of drinking water was constructed in the end of 2010, as a result of acute water scarcity (production of 2,300 m 3 per day).
Sewerage networks are not common and wastewater treatment is even less common. Sanitation is often in the form of individual pit latrines or shared toilets. 70% of investments in water supply and sanitation in sub-Saharan Africa is financed internally and only 30% is financed externally (2001–2005 average). Most of the internal financing is ...
Sustainable sanitation is a sanitation system designed to meet certain criteria and to work well over the long-term. Sustainable sanitation systems consider the entire "sanitation value chain", from the experience of the user, excreta and wastewater collection methods, transportation or conveyance of waste, treatment, and reuse or disposal.

For example, the Trekkopje mine in the Namib desert uses 14 million m 3 /year of high-quality water that must be free of any salt. Saline water extracted through local wells is used for dust suppression, thus reducing the need for freshwater. Furthermore, some of the wastewater is treated and reused, thus further reducing water demand.
Of the wastewater that enters the sewer network, only about 60% reaches the treatment plants. [31] The most common solution used for wastewater treatment in Kenya are waste stabilisation ponds . One of them is the Dandora Waste Stabilisation Pond System which treats the industrial and domestic sewage from the city of Nairobi and is the largest ...
Ecosan concept showing a separation of flow streams, treatment and reuse; 2014 illustration. Ecological sanitation, commonly abbreviated as ecosan (also spelled eco-san or EcoSan ), is an approach to sanitation provision which aims to safely reuse excreta in agriculture. [ 1] It is an approach, rather than a technology or a device which is ...
April 2021. Bugoloobi Wastewater Treatment Plant ( BWTP ), also Bugoloobi Sewerage Treatment Plant ( BSTP ), is a wastewater treatment project in Uganda. It is the largest wastewater treatment plant in the countries of the East African Community, and capable of processing 45,000,000 liters (45,000 m 3) of wastewater daily. [1] [2]
However, around 6 million people in Zambia still lack access to "at least basic water". As for sanitation, in 2015, 31% of the total population had access to "at least basic sanitation " service. 49% of the urban population had access to basic sanitation and 19% of the rural population. There are still around 11 million people who lack access ...
