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


5/19

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.


6/19

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


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.


8/19

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


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


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


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


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


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


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.
