We all need water. Plants as well as animals also need water to stay alive.
We need water for drinking, bathing, cooking, and gardening.
Rain is the main source of water on the earth. The rainwater fills up the ponds, lakes, rivers and oceans. These are called the waterbodies. These waterbodies give us surface water.
Some of this water also seeps deep into the ground. This is called groundwater. We get the groundwater by digging a well, handpump or a tube well.

The water that we get directly from these sources is not clean. It has impurities like dirt, sand and germs. This water is first purified and then used. In towns and cities, it is supplied into our homes through taps.

The water that reaches our home looks clean. However, it still needs to be made safe for drinking. This can be done either by boiling the water or by filtering it. Boiling kills the germs present in the water. It can also be purified using water filters and water purifiers. Clean drinking water is called potable water. This water is tasteless, colourless, odourless and germ free.
If we drink unclean water, we may suffer from diseases like jaundice, cholera and typhoid.
Storing Water
At home, we store water in containers like the pot, bucket, tub and overhead tank.
Do you know
- Our body is actually about 65% water.
- Water stored in dams across the rivers is used to produce electricity.
- The Egyptians were the first people to record methods for treating water.
The water available for our use is limited. So, we should not waste water. Given below are some tips to save water.
Another good way to save water is through rainwater harvesting. Rainwater is collected in big tanks with the help of pipes. It is then filtered, purified and stored. This water can then be used when needed. Nowadays, many houses, schools and factories store water in this way.

In Bikaner, Phalodi and Barmer of Rajasthan, almost all the houses traditionally had underground tanks or tankas for storing drinking water.
