One out of three people has no access to a nearby clean toilet or latrine. Unsound sanitary installations and unhygienic habits in the vicinity of a drinking water supply can cause this source to become contaminated. Here, Protos has adopted an approach where behavioural change is the key. Our local partners promote and provide training in good hygienic practices such as the systematic use of a latrine, washing hands, fetching and properly storing clean drinking water. Occasionally we build latrines, but more often we prefer to stimulate the demand for sanitary installations from within the community and support small local companies in meeting this demand. Furthermore, we assist local authorities in meeting their responsibilities with regard to sanitary installations.
