Water Shortage In The United States

Water shortage in United States is a potential problem. Today almost no one consider how serious the issue is. Water is the main resource of our living; we have it and do not realize how much water we waste. In U.S.A. there are over usage of water in irrigation, agriculture, industry and over usage in residential purposes. According to CBS News report (Strassmann, 2010), average American uses about 150 gallons every day, while Englishmen use 40 gallons, Chinese – 22 and Kenyan - 13 gallons. Strassmann also points out that scientists count, that consumption of water is much more than supply, so that in next three years 36 states will faced the problem of water shortage. Nowadays, Las Vegas, Texas, California, Colorado,

Seas and oceans are 97% of all water, so if we will take just few per cents it would be a big help to water crisis. It is using at coast areas, where is the huge amount of salt water. But this way of producing fresh water is very expensive and spent much energy. There are several types of desalination, such as multi-stage flash distillation, reverse osmosis. These methods almost always do not dip themselves. As Heimbuch (2010) states, it could be said, that more practical and economical ones would be forward osmosis and low temperature thermal desalination, but they are not explored

Water from rains is one of the cleanest because of distillation process, but of course our current pollution effects to its purity. Rainwater harvesting is seems to be a good solution for areas, where are no seas, no groundwater but it rains regularly. The term “rainwater harvesting” is usually taken to mean “the immediate collection of rainwater running off surfaces upon which it has fallen directly”. (Penn, C. 2008) Water usually collects by special roofs, such as tiled roofs, thatched or palm leafed roofs. It tends to be no water woes if humans would use it more rational. Americans always consume a lot of water, but seldom consider about the necessity of economy. Economy at home is likely to be an effective method against water shortage. Government should provide educational programs for people about how to save water. For example, person can use the bath not shower, or reduce the time of having a shower. Also nowadays there are huge variety of water-economy technologies and gadgets, using in order to spare, starting with low-tech toilets and touch taps ending with water-control
