This portal describes sanitation technologies which can be applied from the household level to the village level.
A complete sanitation system does not consist of only one technology, but rather a chain of technologies, each taking care of a specific function, such as the toilet, 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.
For a helpful sourcebook in the training of professionals for the sanitation and water sector, browse or download the set of animated PowerPoints called Sustainable Sanitation, by clicking the pink box on the right.
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.
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 Single Pit System||2 Waterless System with Alternating Pits||3 Pour Flush System with Twin Pits||4 Waterless System with Urine Diversion||5 Blackwater Treatment System with Infiltration||6 Blackwater Treatment System with Sewerage||7 (Semi-) Centralized Treatment System||8 Sewerage System with Urine Diversion|
