Availability of fresh water in rural and semi urban areas is a major problem as they do not have connection with government water grid. Surface water is polluted by human, agriculture and industrial waste. Ground water, in many parts of the world is found to have excess impurities like salt, Flouride, Nitrate, Iron, Chromium, Lead, Cadmium, Arsenic, Uranium etc. largely due to over extraction from borewells.
Extensive use of ground water for agriculture, industrial or any other purpose are increasing salinity (TDS levels) and hardness in raw water. Consumption of this quality of water results in many diseases including chronic kidney diseases. In Urban areas people treat this raw water through Reverse Osmosis and Softening plants resulting in huge wastage of water; This is not only exacerbating the water crisis but also adding huge electricity bills, carbon emissions that fuels effect of Climate Change.
