Water is an important component of human body and is the need of life (Muhammad et al., 2012). Presence of deterious chemicals and pathogenic microbes can cause a serious health problem, leading to infections and death (Lima et al., 2005). The drinking water contaminated with any pathogenic bacteria is unsafe for human consumption and household use (Muhammad et al., 2012). Access to safe drinking water is not only the prime need for survival and health but is also basic human rights (WHO, 2000). Safety of drinking water remains an important public health concern particularly in emergency situations (Ferretti et al., 2010). Pathogens that cause diarrheal diseases are being linked with contaminated water consumption, such pathogens are the main cause of gastrointestinal infections. The childhood mortality rate due to diarrheal diseases is 2.5 million each year (Muhammad et al., 2012). Each year approximately five million children die due to the use of unsafe water (Shar et al., 2010). Approximately 1.8 million
