Water For Every Household

Can You Recall?

We need water all the time. We have to store water in the house so that we can get it when we need it. Earlier brass and copper pots as well as earthen pots were used to store water. Ask your parents or grandparents for the names by which these different pots were known. People also built tanks in their houses to store water. Nowadays, steel or plastic is also used to make different containers for storing water.

The picture below shows some containers used for storing water at home.

Can You Tell?

Which of these have come into use more recently?

What materials are used to make these different containers?

What are the advantages of having a lid and a tap on the container?

Teacher's Note

In India, many families still use clay pots (matka) to store water because it keeps water cool naturally. Today, plastic and steel containers are common in cities.

Exam Trick

Remember: Lid and tap = clean water. Just like you close your lunchbox to keep food fresh, a lid and tap keep water clean and germs out.

Points to Remember

We need water every day in our house.

Water was stored in clay pots, brass pots, and copper pots long ago.

Today, steel and plastic containers are used to store water.

A lid and a tap on a container keep water clean and easy to use.

Care Of Drinking Water

To ensure good hygiene, we must have safe drinking water. If we consume contaminated water, it can cause diseases. That is why we take special care of the water we store for drinking and cooking.

We keep the drinking water containers covered. This prevents dust and other rubbish from entering the water. If we dip our hands in the water to take it out, the dirt on our hands can enter the water. So we use a dipper to take the water and we replace the lid at once.

But the best method of taking water is to have a tap on the container. This way, it becomes easier to take the water, and it also prevents contamination.

When the water in a container is finished, we wash the container well before refilling it. If we take such care, drinking water remains clean.

Teacher's Note

In many Indian homes, water is stored in covered pots with a tap or a dipper to keep it clean and safe for drinking.

Exam Trick

Remember: Covered container + tap = safe drinking water. The lid stops dirt, and the tap stops your hands from touching the water.

Points to Remember

Safe drinking water is very important for good health.

We must cover water containers to keep dust and dirt away.

Using a tap is the best way to take water from a container.

We must wash the container before refilling it with water.

Clean water keeps us healthy and safe.

Do You Know?

Water Does Not Become Stale

Some people believe that the previous day's drinking water must be thrown away and fresh water stored every day, because the previous day's water becomes stale. But this is a misconception. Throwing away that water amounts to wasting good water. We should use drinking water for other purposes only if it gets dirtied due to some reason.

Use Your Brain Power!

Why have people begun to use plastic or steel containers for storing water?

Try This

Do this under adult supervision.

Take a plastic bottle. Cut off its upper narrow portion. Make four small holes on the four sides of the bottle near its base.

Cut a spent ball-pen refill into four pieces. Fix one piece into each of the four holes tightly.

Teacher's Note

This simple activity shows children how water flows through pipes. In India, water distribution systems use pipes to bring water to every house.

Exam Trick

Remember: Four holes = water flows from four places. This shows how one water tank can supply water to many homes through pipes.

Points to Remember

Pipes help distribute water from one tank to many houses.

Water flows downward naturally but needs force or machines to flow upward.

Taps on pipes let us control how much water we take.

One water tank can supply many different areas at the same time.
