2. 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.

4. 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

6. 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

7. Pollution of water
DOMESTIC POLLUTION
Safe water supply
Sanitation – open defecation
Drainage
Solid waste disposal
AGRICULTURE POLLUTION
Pesticides
Fertilisers
Over extraction of ground water

8. Water and health

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.

Save Water : Reduce the
demands on scarce and ground
water sources.
Stored water can be used in non
monsoon months.

15. 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.
