In its modern concept, environment includes not only water, air and soil but the social and economic condition under which we live (Park, 2011). The key to mans health lie largely on his environment. Infact, much of mans’ ill-health can be traced to adverse environmental factors such as water, soil and air pollution poor housing conditions, presence of animal reservoir and insects vectors of diseases, which poses serious threats to man’s health. Man is often responsible for the pollution of the environment through urbanization, industrialization and other human activities. According to the National sanitation foundation of USA, the word sanitation is defined as “way of life that is expressed in the clean lines of homes, farms, business, premises, neighborhood and community Parks (2011). Furthermore, World Health Organization (WHO) defines sanitation as the provision of facilities and services for the safe disposal of human urine and faeces and other waste materials (UNICEF and WHO 2012).
