4.  Hi everybody here in this presentation I
want to teach you about the water and
its uses and I hope that you finish whit the
motivation to take care of it .

5.  Water is a molecule that consists of two hydrogen
atoms and one oxygen atom. When these atoms
are heated to a high temperature, they join to
form water. The scientific way to write this molecule
is "H2O." Since most of the water on earth was
created when the earth was forming, the water
you are drinking today may have been a drink for
a dinosaur or maybe a part of Cleopatra's bath
water!

6. We need to take
care of water
The water is a
resource that no all
people have so we
need to take care of it
HOW DO PEOPLE
USE WATER
RESOUCES
People use water
resource for make
good things like cook ,
wash , drink and a lot of
more uses.

7.  Water resources are sources of water that are
useful or potentially useful to humans. Uses of water
include agricultural, industrial, household, recreatio
nal and environmental activities. Virtually all of
these human uses require fresh water.
 97% of water on the Earth is salt water, leaving only
3% as fresh water of which slightly over two thirds is
frozen in glaciers and polar ice caps.[1] The
remaining unfrozen freshwater is mainly found as
groundwater, with only a small fraction present
above ground or in the air.[2]

8.  Fresh water is a renewable resource, yet the world's
supply of clean, fresh water is steadily decreasing.
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. Awareness of the global importance of
preserving water for ecosystem services has only
recently emerged as, during the 20th century,
more than half the world's wetlands have been lost
along with their valuable environmental
services. Biodiversity-rich freshwater ecosystems are
currently declining faster than marine or
land ecosystems.[3] The framework for allocating
water resources to water users (where such a
framework exists) is known as water rights

9.  Agricultural : It is estimated that a 69 % of world
water irrigation is necessary to grow any crop at all,
in other areas it permits more profitable crops to be
grown of enhances crop yield. Agriculture is a small
but growing agricultural use of water. Freshwater
commercial fisheries may also be considered as
agricultural uses of water.

10.  Industrial: It is estimated that a 15 % of
world wide water use is industrial . Major
industrial users include power plants,
which use water for cooling or as a
power source.

11.  Household : It is estimated that a 15 % of
worldwide water use is for household
purpose . These include drinking ,
cooking and gardening.

12.  Recreation : Recreational water use is
usually a very small but growing
percentage of total water use.
Recreational water use is mostly tied to
reservoirs. Recreational usage may
reduce the availability of water for
others users at specific times and places.

13.  Environmental : Explicit environmental
water use is also a very small but growing
percentage of total water use .
Environmental water usage includes
artificial wetlands , artificial lakes
intended to create wildlife habitat, fish
ladders around dams , and water
releases from reservoirs timed to help fish
spawn.

14.  Water is probably the most important
resource on earth. We need water to
grow and stay alive. In fact we could
only live for a few days drinking water.
We also need water to grow plants and
care for animals , cook our food and
brush our teeth, flush the toilet, and
wash our clothes.

15.  You might think that there is plenty of water for everyone to
use . But did you know that most of the water is ocean water
? Ocean water is very salty. You cant drink it or use it for
growing plants , cooking food, bathing or washing clothes.
The water use for these things is called freshwater. It comes
from rain or snow that falls in rivers and lakes. If is also found
stored in rocks beneath the ground . Some people don’t
have enough freshwater where they live. It is important for
everyone to conserve, or save water so that there is enough
for everyone.

16. › When your family washes clothes, be sure that the
washer has a full load.
› When your family washes dishes, be sure that there is a
full load in the dishwasher, or fill the sink with water to
wash the dishes, then refill the sink to rinse them.
› Take shorter showers.... and get a special shower head
that uses less water.
› Take shallow baths. You don't need to fill the tub to the
brim to get clean.
› Shut off the water when you are brushing your teeth
and washing your hands. Just run it long enough to wet
your toothbrush or your hands, and then shut it off until
you need to rinse.

17. › Keep a jug of water in the refrigerator so that you
don't need to let the water run down the drain
while it cools for a drink.
› Find out how the landscape is watered at your
house, and how can it be done with less water.
› Tell your parents or teacher if some faucet is
leaking at home or at school. Explain to them that
the water that is dripping is costing them money!
› Don't use your toilet as a wastepaper basket. It has
its purpose, and use it for that only.
› If you run water waiting for it to get hotter or
colder, don't let it go down the drain. Save it in a
bucket to use later to water plants.
› Always, always shut off the faucet when you are
finished using the water.

18.  By keeping water as clean as possible
› Don't put anything in streams, lakes, and
rivers that should not be there.
› Don't pour chemicals down the drain or on
the ground.
› Don't pour chemicals down the storm sewer.
› Use soaps and detergents carefully.

19.  August 2009
 U.S. Water News Online
SALT LAKE CITY — Local officials are worried about a pending deal
between Utah and Nevada to pipe water from Snake Valley to Las
Vegas.
The deal would split the shared Snake Valley aquifer, eventually
allowing water to be piped south to Las Vegas. Environmentalists are
concerned that the project could dry up the valley around Great
Basin National Park and send dust storms toward Utah's Wasatch
Front.

20.  The Utah Department of Natural Resources says a draft agreement
on the plan is likely by August or September, but officials from
counties in both state are already wary of the deal.
“By the time they realize what the impacts are, it'll be too late,”
Millard County Commissioner Daron Smith said.
Mike Styler, director of the Utah Department of Natural Resources,
said the plan protects existing water users, air quality, and fish and
wildlife. Nevada officials aren't scheduled to hear the Southern
Nevada Water Authority's case for the pipeline until 2011, so
opponents want Utah to hold off on an agreement.
Salt Lake County Mayor Peter Corroon said scientists still need to
resolve how the pumping would affect the aquifer, desert
vegetation and the potential for dust pollution if the region
becomes even drier.
“It might hurt our air quality and our pocketbook,” Corroon said.
Officials on the Nevada side of the border are also concerned.
Gary Perea, a White Pine County, Nev., commissioner, wants the
states to hold off for at least another year and wait for the
groundwater studies.

21.  Utah Association of Counties attorney Mark Ward, who
represents Juab, Millard and Salt Lake counties in the issue,
said county officials fear the agreement will protect water
currently used by Utah residents and allow the remainder to
be pumped to Nevada.
“The counties have pressed this repeatedly with the state,
that they should slow way down on the negotiations,” Ward
said.
The Southern Nevada Water Authority argues the fear is
overblown. Spokesman J.C. Davis said the sooner the details
can be worked out, the better the agreement will be for
everybody involved.
Lt. Gov. Gary Herbert, who is set to take over when Gov. Jon
Huntsman resigns his post once he is confirmed as U.S.
ambassador to China, plans to discuss the plan with the
public once he is more familiar with it.
“We want to make sure we understand this issue well,” said
Jason Perry, Herbert's transition director. “It's going to require
a lot of public participation.”

 Colombia: government seeks to moderate water consumption
through rate increase
 January 29, 2010 · Leave a Comment
 The Colombian government will issue a presidential decree in
January 2010 to increase water tariffs in an effort to moderate water
consumption in the country, local paper La República reported.
 Rates will be adjusted in each region according to water usage and
climate variables, environment and housing minister Carlos Costa
was quoted as saying.
 Households located in cold areas with a monthly consumption of
more than 28m3 will experience rate increases, as will households in
warm areas that consume over 34m3/month and those in hot areas
with a monthly consumption exceeding 35m3, the report said.

24.  According to government projections, some 100
municipalities are at risk of water rationing in 2010,
as a result of the El Niño weather phenomenon,
which affects rainfall amounts.
 Bogotá city does not appear to be at risk and is
using its potable water reserve to support the water
supply in its surrounding municipalities, according
to the report.
 A total of 13 municipalities are already
experiencing water rationing, including Villeta, La
Mesa, Apulo, Barichara and San Juan
Nepomuceno.
