Sanitation, as described by the World Health Organization (WHO), refers to the provisions of facilities and services for the safe disposal of human urine and feces. In the 21st century, lack of access to sanitation facilities by 40% of the world’s population sounds like an international scandal. This means that about 2.6 billion of the world’s citizens, majorly in developing countries, still rely on a bucket, a bush or a back street for excretion. For years, it was an inheritance of the colonial period to put emphasis on copying the western sanitary achievements by providing sewage coverage in developing countries.
