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

children.
88% is attributed to unsafe water
supply, inadequate sanitation and
hygiene.

Stored water can be used in non monsoon months.
Catch it in anything that
