Portail d'Hygiène
This portal describes sanitation technologies which can be applied from the household level to the village level.
A sanitation system does not consist of a single technology described below. A complete sanitation system consists of a chain of technologies, each taking care of a specific function, such as the toilet, the transportation, and treatment. Each technology below is dedicated to one particular function in this chain. An example is given at the end of this page.
Systèmes d’assainissement
Below, sanitation technologies are presented in different functional groups: User interface (Toilets, urinals, handwashing), Collection and Storage / Local Treatment, Conveyance, (semi-) Centralized Treatment, and Use of products / disposal.
Sanitation systems
In this section we give an example of a complete sanitation system, which consists of a chain of technologies. Reading the icons in the illustration below from the left to the right we have a Urine Diverting Dry Toilet connecting to Storage tanks, where the faeces are taken away through Human-Powered Emptying and Transport to be processed through Co-composting and then finally be used through Application of Compost - Eco-Humus and the Application of Urine.
The table below lists eight different examples of sanitation systems, going from very simple to more complex. Of course, many other systems are possible, depending on the local context.
1 Système à une fosse | 2 Systèmes à fosses sèches alternées | 3 Système à chasse avec double fosse | 4 Système à fosse sèche avec séparation d’urine | 5 Système de traitement des eaux vannes avec infiltration | 6 Système de traitement des eaux vannes avec réseau d’égout | 7 Système de traitement (semi-) centralisé | 8 Système de réseau d’égout avec séparation d’urine |
