Transcript SAVE WATER - Water harvest

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

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 sources
 Wash hands after going to the toilet
 Use toilets – don’t openly defecate
 Wash hands before eating
 Wash vegetables well before
cooking
 Cover all food

Personal hygiene
Have bath daily
 Comb hair daily
 Brush teeth daily twice
 Cut your nails
 Wash hands with soap after going to
toilet
 Wash hands before eating
 Wear 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


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

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 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
depletion
ground water
 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.

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
