prepare a comparative chart to indicate how your grandparents get water and how you get water for your daily use
Answers
During the times of our grandparents, they mostly collected water from the rivers.
Rivers, those days, were not as polluted as they are now.
As a result, river water was enough to meet the daily needs of the people.
But now, rivers have become excessively polluted due to disposal of sewage, factory and agricultural wastes, garbage matter etc.
So river water is treated first by the Municipal Co-operation after which they are supplied to households.
