Importance of Water Purification- Why is it needed?

The shortage of groundwater is badly increasing everywhere. In addition, heavy pollution is worsening the situation. According to the UN Human Rights Report, the world is fast approaching a devastating situation where only the wealthy can afford basic resources in the face of fatal calamity. In some of the places in India, the disaster has already arrived. Chennai, the sixth-largest city in India, has nearly been dry in mid-2019. In this context, we can understand the Importance of Water Purification in India.

According to Aljazeera, By 2020, at least 21 cities in India, including Chennai, Hyderabad, Delhi, and Bengaluru might run out of groundwater, affecting around 100 million people.

However, you might not have faced such a situation of the water crisis yet. But, the water you drink might not be fully safe for drinking.


This is because the water you drink might be directly from the borewell or even from corporation/ municipal distribution without purification. As a matter of fact, municipal water is definitely treated. But, when this water passes through the pipes placed underground to reach you, there could be leakage. It has to come a long way through rusty and dirty pipes until it gets to you. Eventually, the water might get contaminated. The water that finally arrives at your taps may contain rust, germs, and impurities.

During monsoon, the chances of contamination increases. In such a situation, a person may get sick if he/she drinks the water directly or even cook with it.
