THE TEN USES
The availability of water always has played an important part in
determining not only where people can live, but also their quality of life.
Even though, there always has been plenty of fresh water on earth, it has
not always been available when and where it is needed, nor is it always
of suitable quality for all uses. Water must be considered as a finite
resource that has limits and boundaries to its availability and suitability
for uses. Everyone understands that water is essential to life. But many
are only just now beginning to grasp how essential it is to everything in
life, we must have water for it is one of the most vital natural resource
for all life on earth. People on earth uses water in different ways these

are; for Agriculture, Industrial, Commercial, Domestic, Public supply,
Livestock, Mining, Thermoelectric,
To begin the uses of water in agriculture covers a wide range of
consumptive and non-consumptive water uses in all the agricultural sub-
sectors related to ethical conflicts and significant social, economic and
environmental issues. But one of the main uses in agriculture is
irrigation. Irrigation uses about 70 percent of total globally abstracted
water volumes, while total agricultural use represents about 92 percent
of total uses of flowing water and rainwater. Within the agriculture
sector without the reach of water large scale farming could not provide
food for the worlds large population without the irrigation of crop fields
by water gotten from rivers, lakes, reservoirs and wells. The use of water
isnt just important for in irrigation but also for the production of crops.
Without the use of it there werent be any good produce of food on plots
where the farmers now werent have any goods to sell to their
customers.

Industries that produce metals, wood, paper, chemicals, gasoline, oils,
and most other products all use water in some part of their production
process. Industry depends on water, much like agriculture and domestic
households depend on water. Industrial reliance on water makes it
essential to preserve water in every aspect possible and make sure water
pollution is kept at minimal levels. Industry is reliant on water for all
levels of production. It can be used as a raw material, solvent, coolant,
transport agent, and energy source. Many litres of water are used to
produce glass, plastic, along with some fabric components. Fresh water
is not just for drinking anymore. Car washers are a great example of an
industry that uses gallons and gallons of water everyday. People in
developed countries use them frequently without really thinking about
all of the water being used. It is the Core countries that use the majority
of freshwater in industry.
Commercial use, includes fresh water for motels, hotels and civilian and
military institution. Commercial water use during 1990 was an estimate
of 19 percent. Over one-half of the increase occurred the result of
8/7/2019 Natural Science- Water
7/19
including offstream fish hatcheries in this category. Commercial use
represents about 2 percent of total freshwater use for all offstream
categories. Commercial withdrawals were an estimated 2,390 Mgal/d.
Surface water was the source for about 62 percent of commercial
withdrawals. Public suppliers delivered about 5,900 Mgal/d of
freshwater to commercial users during 1990; this accounted for about 15
percent of total public-supply withdrawals.
Domestic uses,of course some of the most important uses for water areat our homes. Domestic water use is water used for indoor and outdoor
household purposes all the things you do at home: drinking, preparing
food, bathing, washing clothes and dishes, brushing your teeth, watering
the yard and garden, and even washing the dog. Water generally gets to
our homes in one of two ways. Either it is delivered by a town/county
water department (or maybe from a private company), or people supply
their own water, normally from a well. The majority of people (about 86
percent) gets their water delivered from a public-supply system. This
makes sense, as people now largely live in urban centres.
8/7/2019 Natural Science- Water
8/19
In the Public supply uses, as we might know better as the country and
town water departments, which are vitally important to all populations.
The government of privately non facilities withdraw water from rivers,
lakes, and reservoirs, then deliver it to our homes business, and schools.
In some countries as the United States, majority of the population
nowadays gets their water in this manner. The public supply water is
used for public services as pole, parks, and public buildings.
Livestock water use is water associated with livestock watering,
feedlots, dairy operations, and other on-farm needs. Livestock includes
dairy cows and heifers, beef cattle and calves, sheep and lambs, goats,
hogs and pigs, horses, and poultry. Other livestock water uses include
cooling of facilities for the animals and animal products such as milk,
dairy sanitation and wash down of facilities, animal waste-disposal
systems, and incidental water losses
Like all other industries, mining corporations need water to make bare
rock give up its valuable minerals. Mining has played an important part
in the development of this Nation. Even before the first European
8/7/2019 Natural Science- Water
9/19
settlers set foot on this continent and mined coal to heat their homes,
Native Americans were using coal to bake clay for vessels. The United
States now produces a wide variety of mined commodities from gold to
coal to "exotic" minerals used in everything from pharmaceuticals to
jewelry to high-tech products. All these products would not be possible
without the use of water in mining. Mining water use is water used for
the extraction of minerals that may be in the form of solids, such as coal,
iron, sand, and gravel; liquids, such as crude petroleum; and gases, such
as natural gas. The category includes quarrying, milling (crushing,
screening, washing, and flotation of mined materials), re-injecting
extracted water for secondary oil recovery, and other operations
associated with mining activities. All mining withdrawals were
considered self-supplied.
Production of electrical power results in one of the largest uses of water
worldwide. Water for thermoelectric power is used in generating
electricity with steam-driven turbine generators. In 2005, about 201,000
million gallons of water were used to produce electricity (excluding
8/7/2019 Natural Science- Water
10/19
hydroelectric power). Surface water was the source for more than 99
percent of total thermoelectric-power withdrawals. In coastal areas, the
use of saline water instead of freshwater expands the overall available
water supply. Thermoelectric-power withdrawals accounted for 49
percent of total water use, 41 percent of total freshwater withdrawals for
all categories, and 53 percent of fresh surface-water withdrawals. One of
the main uses of water in the power industry is to cool the power-
producing equipment. Water used for this purpose does cool the
equipment, but at the same time, the hot equipment heats up the cooling
water. Overly hot water cannot be released back into the environment
fish downstream from a power plant releasing the hot water would get
very upset. So, the used water must first be cooled. One way to do this is
to build very large cooling towers and to spray the water inside the
towers. Evaporation occurs and water is cooled. That is why large
power-production facilities are often located near rivers, lakes, and the
ocean.

The uses of water are important in different ways and meanings to
people where they get there income and life living from people.

SCENARIO
Many people believe that the important of water is to be ignored. But in
some places it is an important asset to them. Now, as we see it water is
at the tip of our fingers in uses. Everyone is using it for different
purposes and most of all for agricultural, domestic and industrial.
Since we are living in a world of limited water many countries would
suffer it badly because they would not have enough sufficient water to
do their daily bases. Many industries would be low on their incomes
daily as the shipping industries. Farmers werent have enough water to
irrigate their crops, where they too would not be able to produce any
good crops and making any money, the economy would be on a down
fall. People would die and also diseases would arise. When we use water
to or leisure pleasure we are putting our self in danger, with the access of
the water we are getting now in the year 2025 we will all be complaining
and suffering for the water we did not put in use in the years back. Many
people would die, the population would low and persons would not be
8/7/2019 Natural Science- Water
13/19
able to function right. Children would suffer from diseases such as
typhoid, cholera and dysentery.

ANALYSIS
PROJECTION AND OPINION
Yes I do think that this figure is likely to increase. Because water
scarcity occurs even in areas where there is plenty of rainfall or
freshwater. How water is conserved, used and distributed in
communities, and the quality of the water available can determine if
there is enough to meet the demands of households, farms, industry and
the environment. It also affects one in three people on every continent of
the globe. The situation is getting worse as needs for water rise along
8/7/2019 Natural Science- Water
15/19
with population growth, urbanization and increases in household and
industrial uses. Almost one fifth of the world's population (about 1.2
billion people) live in areas where the water is physically scarce. One
quarter of the global population also live in developing countries that
face water shortages due to a lack of infrastructure to fetch water from
rivers and aquifers. Poor water quality can increase the risk of such
diarrhoeal diseases as cholera, typhoid fever and dysentery, and other
water-borne infections. Water scarcity can lead to diseases such as
trachoma (an eye infection that can lead to blindness), plague and
typhus. A lack of water has driven up the use of wastewater for
agricultural production in poor urban and rural communities. More than
10% of people worldwide consume foods irrigated by wastewater that
can contain chemicals or disease-causing organisms. 1,800 million
people will be living in countries or regions with absolute water scarcity
by 2025, and two-thirds of the world population could be under stress
conditions. Water scarcity causes enormous problems for populations
and societies. The available water is not sufficient for the production of
food and for alleviating hunger and poverty in some regions, where quite
8/7/2019 Natural Science- Water
16/19
often the population growth is larger than the capability for sustainable
use of the natural resources. The lack of water does not allow industrial,
urban and tourism development to proceed without restrictions on water
uses and allocation policies for other user sectors, particularly
agriculture. In regions of water scarcity the water resources are probably
already degraded, or subjected to processes of degradation in both
quantity and quality, which adds to the shortage of water. Health
problems are commonly associated with scarcity, not only because the
deterioration of the groundwater and surface waters favours water borne
diseases, but also because poverty makes it difficult to develop proper
water distribution and sewerage systems. Water conflicts still arise in
water stressed areas among local communities and between countries
despite legal agreements, since sharing a very limited and essential
resource is extremely difficult. Poverty associated with water scarcity
generates migratory fluxes of populations within countries or to other
countries where people hope to have a better life, but where they may
not be well received. Water for nature has become a low or very low
priority in water stressed zones. Preserving natural ecosystems is often
8/7/2019 Natural Science- Water
17/19
considered a superfluous use of water compared with other uses that
directly relate to healthy human life, such as domestic and urban uses, or
that may lead to the alleviation of poverty and hunger, such as uses in
industry, energy and food production. However, the understanding that
natural ecosystems, namely the respective genetic resources, are useful
for society is growing, and an effort to protect reserve areas is already
developing, even in water scarce regions.
