Community-based Water Quality Improvement in a Rehabilitated Slum Building

Water being an indispensable necessity of life, it is imperative that every human being has access to clean drinking water. However, for a large population of the globe, this remains either difficult to attain or actually impossible. According to a 2009 United Nations World Water Development Report, only 54% of the world’s population had a piped connection to their dwelling, plot or yard, and 33% used other improved drinking water sources. The remaining 13% (884 millionpeople) relied on unimproved sources. 

The rising populations are making matters worse. More than 60% of the world’s population growth between 2008 and 2100 will be in sub-Saharan Africa (32%) and South Asia (30%) where the water stress is already severe. According to this report, an estimated 90% of the 3 billion people who are expected to be added to the population by 2050 will be in developing countries, many in regions that are already experiencing water stress and the current population does not have sustainable access to safe drinking water and adequate sanitation. The same report also mentions the fact that more than 5 billion people, i.e., 67% of the world population – may still not be connected to public sewerage systems in 2030. Read more...................
