The quality of drinking water is falling day by day. It is no longer as clean as it was during our ancestor’s time.
Primary reasons why tap-water may no longer be safe for human consumption are:-
Climatic changes, low rainfall and uncontrolled industrialization has led to raise levels of waste being disposed into our water sources such as rivers, dams and ground well water.
Rivers are no longer sufficient to meet society’s ever increasing demand of drinking water and hence there is an increased reliance on ground well water, which contains excessive levels of dissolved impurities making the water hard (salted).
Due to ever increasing pollution levels, the water sources are under alarming stress and are getting polluted with dissolved impurities, bacteria, viruses and cyst.
Aging pipeline network and poor maintenance results in municipal water getting contaminated by the time it reaches our homes.
Since the demand for municipal water is greater than the supply and due to the onset of multi storied buildings, the practice of storing water in overhead tanks has become more common. These storage tanks are not airtight and become breeding grounds for unwarranted harmful micro-organisms like bacteria and viruses.
