Improved Sources of Drinking Water

Safe drinking water has been a major public health concern. Source of drinking water regulates the safety of drinking water. UNICEF (n.d.) defined the “improved drinking water sources” as sources “that, by nature of their construction or through active intervention, are protected from outside contamination, particularly fecal matter”. UNICEF(n.d.) categorized public taps or stand popes, tube wells or bore holes, protected dug wells, protected springs and rainwater collection as improved water sources and unprotected dug well, unprotected spring, surface water such as rivers, lakes and ponds as unimproved drinking water sources.

Proportion of global population using improved sources of drinking water increased from 1990(76%) to 2011 (89%) (WHO, 2013). In Europe, 98% of the population has access to improved drinking water sources in 2011 which was 96% in 1990 (WHO, 2013). A significant proportion of the world population are still requiring sustainable access to safe drinking water. Eleven percentage of the global population or 783 million people don’t have access to improved drinking water source (UN Water, 2012). According to CDC (2012), 605 million people won’t be able to access improved water sources in 2015 if the current trend continues.

UN Water (2012) estimated the number of people having access to improved sources of drinking water as two billion between 1990 and 2010. According to WHO(2013), proportion of African population with access to improved drinking water sources increased from 50 percentage in 1990 to 64 percentage in 2011. South East Asia has significant increase in the proportion of people having access to improved water sources. Seventy one percentage of the population in south-east Asia were using improved drinking water sources in 1990 which increased to 90 percentage in 2011 (WHO, 2013).
