"Thousands have lived without
love, not one without water."
-
-- W. H. Auden
Where
there is water, there is life. Life exists around numerous uses
of water which makes it important for survival and luxury. It
is a part of our biosphere that should not be overused, ignored,
or taken for granted. Because of this, water should be conserved
to sustain our domestic needs for the future.

Domestic
Water Use and Demands
-
As world population
is constantly growing, the demand of water increases each and
every day. The luxuries of domestic uses of water have become
a necessity to people in their homes and backyards. Domestic
water is normally characterized by its use inside and outside
the home: washing the dishes, cooking a meal, laundry, bathing,
watering the lawn or garden, and other household activities.
-
-
In
a typical home in the United States, approximately 50% of water
is used in the bathroom. The toilet makes up 26%, while the
shower and sink use 23%. Outside of the house, 35% of water
use is for lawn or garden care. Below is a picture showing more
detailed information of water use inside of a home.

is a table showing specific domestic activities with normal uses
and conservation uses of water. Each activity is displayed to
show the differences between each. This table gives a great indication
that water is a valuable resource.

Due to these individual
and personal habits, domestic use of water is increasing. “Of
all the social and natural crises we humans face, the water crisis
is the one that lies at the heart of our survival and that of
our planet Earth," said UNESCO's director-general, Koichiro
Matsuura, in a prepared statement. "No region will be spared
from the impact of this crisis, which touches every facet of life,
from the health of children to the ability of nations to secure
food for their citizens" (Ehrenman, Mechanical Engineering).

Global
consumption of water has also increased twice as much as the
population during the past 20 years. According to the United
Nations, the demands for access for fresh water are unattainable
to more than one billion people.
-
This
graph shows the percentage of specific countries (Asia, South
America, Australia, Europe, North America, and Africa) withdraw
and consumption rates between the year 1995 and 2025.

Australian
Case Study
- In Australia there
are huge demands for water, (see Australia's
Economy for more information). It is one of the driest countries,
due to an extreme drought that has been occurring for the past
six years. Australia is also one of the top consumers of water
per person in the world. According to the figures below, the domestic
uses of water for Melbourne (based on average household water
consumption) are reasonably similar to those in the southwestern
areas of the United States. In Melbourne, an average family uses
19% of their total water for flushing the toilet and 35% for garden
and lawn watering.

Almost
65% (156 kiloliters) of water consumed per year is used indoors.
But the total water use for an average household in Melbourne,
Australia is 657 liters per day (240 kiloliters per year).
-
-
- As of now, most
households in Australia are supplied with a clean and sufficient
supply of water, but it may not stay this way for long. According
to Global Education, an online source indicates that
“in the next two decades, water use will increase by 40 percent,
and by 2025, nearly two-thirds of the world’s population will
live in regions where water supply is under stress.” These are
situations that should not be taken lightly. Currently, the effort
to conserve water usage throughout the city includes utilizing
all available water and reducing water consumption.

Water
Scarcity
Water
is a vital resource for the survival of all living things. Without
water, life on planet Earth would not exist. According to recent
studies, more than 508 million people in 31 countries face water
scarcity in the world today. It is predicted that by the year
2025, the number of people dealing with water scarcity will be
over 3 billion a year. If this cycle of overconsumption, pollution,
and wastefulness does not subside, our water supply will be severely
diminished.
This
graph shows much more detail about specific countries that are,
or could be, in demand for water in the future.

This is a short poem
written by Sir Alan Herbert. He expresses the joy of water and
how it is needed by all living organisms on the planet Earth.
It sends out a message in that water is not always an available
resource, so the need to conserve, reuse, and preserve water is
the key to survival.

"Water"
-
by Sir Alan Herbert
-
The rain is plenteous but, by God's decree,
Only a third is meant for you and me;
Two-thirds are taken by the growing things
Or vanish Heavenward on vapour's wings:
Nor does it mathematically fall
With social equity on one and all.
The population's habit is to grow
In every region where the water's low:
Nature is blamed for failings that are Man's,
And well-run rivers have to change their plans.
