SAVE WATERSAVE WATER

BY: GOEL & COMPANY LUDHIANA

Did you know that the water you drank this morning might

have been the same water a dinosaur drank millions of

years ago?

There is the same amount of water on Earth today as there

has always been. The water keeps moving around in an

endless cycle called the water cycle.

THE WATER CYCLE

Water evaporates from oceans, rivers and lakes

(water in its liquid form) and rises into the

atmosphere (water in its gas form) where it

condenses to form clouds. Precipitation then

falls to the earth in the form of rain (water in

its liquid) or snow (water in its solid form)

where it flows into oceans, rivers and lakes

and the process begins again

Amount of fresh water in the world …

Of all the water on Earth, only a small amount is available for us to use. It's true!

96.5% of the Earth's water supply is salt water.Only 2.8% is fresh water!

•That 2.8% is divided like this: •0.76% is groundwater (we can use some of this

water) •0.0132% is in lakes and streams (we can use

some of this water) •1.74% is in glaciers and icecaps

•0.001% is water vapor

Pollution of water

DOMESTIC POLLUTION Safe water supply Sanitation – open defecationDrainage Solid waste disposal

AGRICULTURE POLLUTION Pesticides Fertilisers Over extraction of ground water

Water and health The body is comprised of 75%of

water.

We cannot live without water for

more than 24 hours.

1.8 million people die from

diarrhoeal death where 90% are

children.

88% is attributed to unsafe water

supply, inadequate sanitation and

hygiene.

Methods of saving water

You can do something to save the environmentYou can do something to save the environment

Save Water : Reduce the demands on scarce and ground water sources.

Stored water can be used in non monsoon months.

Catch it in anything that

holds waters. Once you

have a container, simply

put a tank/drum beneath

where the rainwater runs

off your roof and you

have started harvesting.
