1.1 BACKGROUND TO THE STUDY.
Waterborne diseases are a major health issue, because of the burden they place on man. Waterborne diseases are caused by pathogenic microorganisms that most commonly are transmitted in contaminated fresh water (Wikipedia, free Online). According to this school of thought, waterborne diseases may result from bathing, washing, drinking, in the preparation of food or the consumption of food thus affected. Thus waterborne diseases can be described as all illnesses that results from having contact with or drinking contaminated water. According to World Health Organization-WHO (2012a), 88.0% of all infectious diseases worldwide and 90.0% of all infectious diseases in developing countries are water-related.
