Portal de Saneamiento

This portal describes sanitation technologies which can be applied from the household level to the village level.

Languages available / langues disponibles

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.

Sanitation technologies

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 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
