11. Creating awareness about wastage of water

due to negligence 

Background

“If you have water, you can think of the future”. The amount of water recommended by the United Nations for drinking, washing, cooking and maintaining proper hygiene is a minimum of 50 litres per person per day, i.e., approximately 2½ large size buckets of water per person per day. Millions of people in our country do not get enough water to meet their requirements. The problem is likely to worsen. It is therefore important that we should use it judiciously and conserve it.

Methodology

1. Notice whether there is any leakage of taps at your home/ school. If there is any leakage put a bucket under it and collect the water leaked.

2. Also estimate the amount of water wasted due to negligence, such as leaving the tap open during washing, shaving, while collecting water, washing of vehicles.

3. Calculate approximately how much water is wasted per day/week.

Conclusion

Conclude by writing a paragraph about your findings.

Follow-up

1. Prepare a slogan on conservation of water.

2. Take initiative to repair leakage of water from pipes, tanks, etc., in school, home or the colony.
