Our primary needs are food, water and shelter; but water is the most important need of every person. Without water, we cannot survive. Even for one day, we cannot live without water. If we have safe and clean water for drinking , we’ll live healthy and prosper. The clean water we drink and which is germless is called potable water. The water we drink in our homes, is supplied by the municipal community. We think that it is safe and germs free but in reality it is not fully safe for using in household works and also for drinking , for the reason that it is filtered in huge tanks ; the big particles and comparatively small particles are filtered but not purified . So we should ensure that we purify the water before drinking.
There are two types of water :
i) The drinking water
ii) The water for household works
There are different sources of water and are classified as :
Natural sources : Rivers , Ponds etc.
Man made resources : Canals, pipeline services etc.
Before drinking water , we should purify it by using certain purifiers . If we drink dirty or unsafe water that contain germs; then we’ll fall ill and certain diseases will be caused such as diarrhoea , typhoid etc. People wash their clothes and their animals also take bath in rivers and pounds ; due to which the water get dirty and several types of germs are generated in the water and are transferred to the infected person to the healthy person . these types of diseases which are transmitted from one person to the another are called communicable diseases . If we take care of some small-n’-small things, then we can maintain our health; because prevention is better than cure. We receive potable water from the canals, rivers, and ponds ; groundwater is also potable. Now, the question is that how is water polluted?
