This document is a virtual booklet about water resources that discusses how water is used by people, the importance of conserving water resources, and some proposals for doing so. It notes that most of the world's water is undrinkable and located in oceans, while sources of fresh water include surface water, groundwater, and frozen water. It outlines how water is used for household, personal, agricultural, industrial, recreational, and environmental purposes. The document also discusses both wasteful and efficient water usage habits.

3. Introduction
This is a virtual booklet about water
resources explaining about how
people use water, how we should take
care of it and many things that we
should learn about water
conservation this booklet is an
attempt to make us aware about the
water problems that we are facing
and how we should to save this
beautiful world.

4. Prior knowledge
Water resources is

the humans and do many things
animals. or

We would have to Water is a
take care of the renewable natural
water because in resources also like

there's not
going to be enough
water for us.

5. Water Resources
 sources of water are
useful to humans. Uses of
water include agricultural,
industrial, household,
recreational and
environmental activities.
Virtually all of these human
uses require fresh water.

6. Fresh water is renewable
resources like soil and air.
The world is supplied by
clean and fresh water and it is
decreasing. Water is one of our
most critical resources, but
around the world it is under
threat.
Water demand already
exceeds supply in many
parts of the world and as
the world population
continues to rise, so too
does the water demand.

7. Water resources are divided:
 Water resources are
divisible into two distinct
categories : the surface-
water resources and the
ground-water resources.
Each of these categories
is a part of the earth's
water circulatory system,
called the hydrologic
cycle, and is derived
from precipitation,
which is rainfall plus
snow.

8. Distribution of water on Earth
This is how the water is distributed
on Earth. If you see here that most
amount of water is in the oceans.

9. This is another
graphic illustration
about the world’s
water and how it is
distributed.
Here also you could
see that the total
volume in the
hydrosphere of
water is 1.386 km2
(100%)

10. Sources of Fresh Water
 Surface water:
Surface water is water in a river, lake or fresh
water wetland. Surface water is naturally
replenished by precipitation and naturally lost
through discharge to the oceans, evaporation,
and sub-surface seepage.

11.  Ground Water:
Sub-surface water, or groundwater, is fresh
water located in the pore space of soil and
rocks. It is also water that is flowing within
aquifers below the water table.

12.  Frozen Water:
Several schemes have been proposed to make
use of icebergs as a water source, however
to date this has only been done for novelty
purposes. Glacier runoff is considered to
be surface water.

14. Uses of water
 Agricultural: It is estimated that
69% of worldwide water use is for
irrigation, with 15-35% of irrigation
withdrawals being unsustainable.
Aquaculture is a small but growing
agricultural use of water.
•Industrial: It is estimated that 15%
of worldwide water use is
industrial. The distribution of
industrial water usage that is varies
widely, but as a whole is lower than
agricultural use.
This is the process of irrigation

15.  Recreational water: use  Household: It is
is usually very small but estimated that 15% of
growing percentage of worldwide water use is
total water use. for household purposes.
Recreational water use These include drinking
is mostly tied to water, bathing, cooking,
reservoirs. sanitation, and
gardening.
Environmental: Explicit
environmental water use is
also a very small but growing
percentage of total water
use.

16. Good and bad uses of water
 Ways people waste water: (How to save it).
 Dishwasher -Dishwashers can waste so much water if you
run it when it is not full. A way to prevent this is to wash
your dishes without use of the dishwasher.
 Brushing Teeth / Washing Dishes WITH the Water Running-
DO NOT keep water running while brushing your teeth/
doing the dishes. When you brush your teeth, wet the
toothbrush first and turn the water off.
 Shaving - When you taking the shower, do you really need
the water running? Turn off the water while you shave your
legs. I put conditioner in my hair, fill cup with water, sit in
the bathtub and shave, with the water off.

17.  If Its Yellow, Let it Mellow. If Its Brown, Flush it Down-
Some people are bothered by this, but it is essential. Every
time you flush the toilet, you waste 10 gallons of water.
 Car Wash-This may be hard for us city folks, but if you have a
lawn, Wash your car on it! Use Biodegradable soap, and a
bucket of water. Only turn on the hose for the final rinse.
 Bath time! Bath time is no longer Fun time. It wastes an
unnecessary amount of water. an average shower uses 1/5 the
amount of water that is needed for a bath!
 Using the Toilet as a Garbage Can- Do Not Do This! Throw
out everything in a garbage can, even if it is tempting to just
throw it in the toilet.
 Hot Water-Only use hot water when absolutely necessary.
Hot water uses a lot more energy, and it isn’t always
necessary.

18. Proposals: How to conserve
water
If you want to learn how to conserver water and protecting the
environment, learning to conserve water is a great way to make a
positive impact. A four-minute shower may not sound like much, but in
reality can cost up to 40 gallons. But don't worry--there are ways to
change water-hogging household habits into leaner, greener activities.
Water Conservation Tips
 Run your dishwasher for only full loads.
 Turn off the tap when you brush your teeth.
 Check your faucets and toilets for leaks.
 Take shorter showers.
 Water your lawn in the morning.
 Use a cover on your pool.
 Wash your car with a nozzle on the hose.

19.  We are fortunate enough to live in a
place where clean water flows freely
on demand, it can be easy to take it
for granted. From your daily
dishwashing routine to your daily
shower, every drop of this natural
resource is precious. Practicing
conservation is not only good for the
environment, but can save you money
in energy bills.

22. Glossary
 Useful: To do something in order to be
helpful.
 Virtually: almost, but not quite.
 Decreasing: smaller increase in output than
input: a situation in which an increase in input
causes output to increase by a smaller
proportion.
 Exceeds: be greater than something- to be
greater than something in quantity, degree, or
scope.
 Replenished: replace used items- to restock
depleted items or material.
 Discharge: carry something out.

23. Conclusion
Finally we have made this
presentation and we hope
you enjoy and like it. I
hope you understood
about this important
topic, for then it would be
easily to talk about it and
share this information to
save the water resources
and more important our
beautiful world.
