SAVE WATERSAVE WATER
School Outreach Programme
Auroville Water Harvest
2005
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
INDUSTRIAL POLLUTION
Chemicals
Untreated water
Ground water contamination
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.
How water is linked to health
Drinking dirty water leads to ill health.Unclean water sources like latrines near hand
pumps or taps can contaminate the water from the ground.
Not washing hands before eating.
Leaving drinking water containers
uncovered.
Household wastes near homes leading
to breeding ground for flies.
No proper drainage near homes –
stagnant water where mosquitoes breed.
How to avoid health problems …
Protect all drinking water sources Drink water from only protected water
sourcesWash hands after going to the toiletUse toilets – don’t openly defecateWash hands before eatingWash vegetables well before cookingCover all food
Personal hygiene Have bath dailyComb hair dailyBrush teeth daily twice Cut your nails Wash hands with soap after going to toilet Wash hands before eatingWear clean clothes
Sanitation
Don’t defecate in the open
Always wash yourself
Use toilets where they are
Don’t defecate near water sources
Dispose of your waste in a responsible
manner
Reuse your bathing water
Environment
Don’t throw your household waste near drinking water sources
Clean your house and surroundings daily Don’t throw paper, plastic, households wastes
into open drains that run through the street Throw litter into a bin and dispose of it properly Don’t cut down trees but grow more plants See that the drains are not blocked
Do you know …..
In 1955, an Indian citizen had 5000 cubic
meters of water at her disposal. Today she
has less than 1500 and it will get lesser in
the future.
More than 1 billion people in the world
have no access to improved water
sources and nearly 2/3 live in Asia.
Why do you think so …..Because there is not enough water left for
everyone…..
So we must try to conserve water and
harvest rain whenever we can
Using water wisely
Lifestyle choices, population growth and
climate change are placing increasing
demands on our water supplies. It's
important that we do not take this precious
resource for granted and that we all use
water wisely to ensure that there is
enough for everyone in years to come.
Saving water starts with you
Check your water meter and track your
bills
Wash fruits, vegetables in a pan of water
rather than running water
Collect the water you use for rinsing
produce and reuse it to water houseplants.
Time your shower to keep it under 5
minutes. You'll save up to 4000 ltrs a
month.
When you give your pet fresh water,
don't throw the old water down the drain.
Use it to water your trees or shrubs.
When you are washing your hands, don't
let the water run while you lather.
Turn off the water while you soap and shampoo
yourself. You can save more than 200 ltrs a
week.
Check all taps and pipes for leakages. A
dripping tap can waste 140 liters a week.
Turn off the water while you brush your teeth
and wash your face. Keep water in a mug. You
waste 6 liters a minutes with running water.
Do one thing every day that will
save water.
REMEMBER – every drop counts
Do you know how much water it takes to …
Bath 50 lts
Brushing teeth with tap running 6 lts per min
Brushing teeth with water from mug
1 lt
Dripping tap 140 lts per week
Washing machines 65 lts
Why do we need to harvest
rainwater?
The ultimate source of water that we utilise
in our daily life is from the monsoons.
The rain used to fall on the ground and
slowly seep inside till the underground
storages were filled up. But today, there
are more building and roads and less
water is being able to seep inside.
At the same time, people are drawing out
more and more water from the
underground storages.
The result being that there is less and
less water for us to use.
Our duty is to see that we can get
enough water to use and also
have some left for the future.
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.
Reduces erosion and storm water run-off
Saves natural resource presently wasted
Prevents ground water depletion
Supports water conservation & self-
dependence
Stores water that would otherwise lead
to flooding.
How do we harvest rain?
Simple ….
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.
Precipitation
Methods of saving water
Rain water harvesting in Chennai and Bangalore
Environmental cleanliness
We depend on nature for life. We need to protect nature or else we get
fucked up Nature fucked up – we pretty big fuck up
Solid waste management
Separate solid wet and solid dry (organic
and ….. Wastes) into different containers
Dig a pit and put organic wastes in to it
with a layer of soil – can be used for
compost
Don’t burn plastic or bury it
Recycle paper, plastic, metal, glass
What schools can do …
Form committees for drinking water and sanitation
These committees will be in charge of the school and see that
the drinking water areas and toilets are maintained well.
Ensure that the school practices water conservation and water
harvesting
Have exhibitions in their own schools for the neighbourhood
