  1. 1.  By : Camila Mideros For : T. Angel Watler 5c
  3. 3.  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 .
  4. 4.  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 Cleopatras bath water!
  5. 5. We need to take care of waterThe water is aresource that no allpeople have so weneed 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.
  6. 6.  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]
  7. 7.  Fresh water is a renewable resource, yet the worlds 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 worlds 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
  8. 8.  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.
  9. 9.  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.
  10. 10.  Household : It is estimated that a 15 % of worldwide water use is for household purpose . These include drinking , cooking and gardening.
  11. 11.  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.
  12. 12.  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.
  13. 13.  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.
  14. 14.  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.
  15. 15. › 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 dont 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.
  16. 16. › Keep a jug of water in the refrigerator so that you dont 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!› Dont 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, dont 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.
  17. 17.  By keeping water as clean as possible › Dont put anything in streams, lakes, and rivers that should not be there. › Dont pour chemicals down the drain or on the ground. › Dont pour chemicals down the storm sewer. › Use soaps and detergents carefully.
  18. 18.  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 Utahs Wasatch Front.
  19. 19.  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, itll 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 arent scheduled to hear the Southern Nevada Water Authoritys 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.
  20. 20.  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, Herberts transition director. “Its going to require a lot of public participation.” TAKEN FROM: fiworr8.html

COLOMBIAN NEWS 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.
  23. 23.  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. Source: [subscription site], 23 Dec 2009
