In Mbuji-Mayi sanitation is not what it should be: due to very rapid urbanisation usually several families share facilities. Sewers are lacking and sanitation is limited to communal latrines. Often 4 to 5 households share one toilet on their plot of land. In the morning, queues are long, even though everyone wants to get out of the poorly-maintained small room as quickly as possible. As it is very difficult to build a sewage system in a city that is bursting at the seams improving the sanitary situation seems a distant prospect.
Yet, waste water management is crucial for public health because a lot of diseases such as cholera and typhoid fever are transmitted via dirty water.
"To raise awareness about the importance of clean toilets and the health benefits associated with them, we came up with the idea of making people's toilet trips a more pleasant experience," explains Lucas Cornet, project manager at Enabel’s.
Now, people want to do this as quickly as possible and leave, without thinking about the next user. This is, of course, because they have to share those toilets, so they are not maintained. The company in charge of operating the sanitation project, Mbuji-Mayi Propreté, offers families a portable toilet to let. This is a toilet with a closed bowl underneath, similar to the toilets in caravans or RVs. A family 'takes ownership' of the toilet. It is used by far fewer people as it can be placed in their own home. The excrement is then collected every two days by a collection service. The collected contents are then placed in a bioreactor and converted by active bacteria into biogas.
The methane gas is then collected and can be used to for instance power a cooker.
