It is the duty of the Corporation or a Municipality to provide clean and safe water to the people. They should also see that the water supply is maintained regularly. Checking that the drinking water is of a satisfactory standard requires better quality control. Rainwater may be harvested (collected) in a tank. It may meet our requirements during dry seasons. Citizens on their part are expected to do their duty. It is the duty of every citizen to see that he or she does not pollute water. They should not waste water while washing clothes or brushing their teeth. They should avoid washing their cars or watering their garden and plants with drinking water. It is a precious thing and should not be wasted.
