3. INTRODUCTION
It is said that freshwater will be the first natural resource to be depleted due to its pollution that is growing increasingly, threatening the ecosystem health and may causing various problems of nutrition and health on a global scale, especially in semiarid regions,such as North Africa and the Middle East. The water scarcity can limit the social and economic development especially on the reagions mentioned above. Thinking about it, it is necessary to create new alternative methods for the sustainable water use as the recycling of rainwater.
4. WHAT IS RECYCLING RAINWATER
Recycling rainwater, also known as rainwater harvesting, collects the rain that fall onto roofs and then stores it in a tank until required for use. When required, the water is then pumped to the point of use or to a secondary tank which distributes the rainwater to the whole establishment, avoiding the demand for mains-water. In the process, a volume of water is kept out of the storm-water management system, to assistance the reducing of flooding risks.
Rainwater harvesting is not a new concept; but, over the last century its use has restricted, with the availability of a clean and inexpensive water source through the mains supply.
Recently, localized flooding started to become a problem once the water demand has begun to exceed supply. Industry experts are now identifying the important role that the harvesting of rainwater, also known as grey water recycling, have to practice in order to improve these two problems.

...groups in order to provide clean and good quality water. In Beijing, the main water distribution system is being complemented by the rainwater collected in houses. When it comes to Africa, some countries such as Guinea-Bissau and Senegal, houses have a rainwater collecting system made of local, organic materials. In Zimbabwe, where the populations mostly has access to water via contaminated open wells, the government is implementing a program to ensure safe drinking water to rural schools through the installation of rooftop rainwater harvesting system.
9. CONCLUSION
Analysing the research and studies for the construction of this report, it can be concluded that recycling rainwater is a sustainable way of water usage and its use have increasingly been assimilated by companies, buildings and people who are interested in smart ways to reuse, recycle and save water.
In the chapter the “Rainy River” of the novel The Things They Carried by Tim O’Brien, O’Brien conveys a deep moral conflict between fleeing the war to go to Canada versus staying and fighting in a war that he does not support. O’Brien is an educated man, a full time law student at Harvard and a liberal person who sees war as a pointless activity for dimwitted, war hungry men. His status makes him naive to the fact that he will be drafted into the war and thus when he receives his draft notice, he is shocked. Furthermore, his anti-war sentiments are thoroughly projected, and he unravels into a moral dilemma between finding freedom in Canada or standing his ground and fighting. An image of a rainy river marking the border between Minnesota and Canada is representative of this chapter because it reflects O’Brien’s moral division between finding freedom in Canada or standing his ground and fighting in the Vietnam war.

There Will Come Soft Rains is a short story that is taking place on August 4, 2026. A nuclear event of some kind has occurred sometime prior to the story, and no signs of human life are evident. There is only one house left standing and it functions independently, and has been completing its daily tasks as if the family still lives there.
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
Rain rot is a severe skin infection in horses, but it is actually a normal inhabitant of the skin on horses. So why does this disease seem to be so serious? Although it lives naturally in the horses skin, rain rot can get very serious if it gets persistently damaged or wet. This can cause an infection to occur. Rain rot is also called rain scald or dermatophilosis. It is caused by dermatophilus congolensis. Dermatophilus congolensis is a gram-positive bacterium and is the etiologic agent of rain rot. It lives within the skin until the skin is disturbed some how. “The bacteria live in the outer layer of the skin and cause from pinpoint to large, crusty scabs.” (Mendell, 2014, January 29.) It can happen when there is high humidity, wetness for a log period of time, high temperature, or even attacks by biting insects. An increase in the number of biting insects can occur if there is high humidity or warm temperatures so it is best to have a cooling spot for the horses. The biting insects are how this disease can spread from horse to horse. Although there is a natural immunity, some horses are more susceptible to it and can get it year after year. Their must be an infected carrier, or even a fomite like a saddle or a blanket that has the organism in the form of a spore. The spores then have to come in contact with the susceptible animal. Once these spores attach, you can start to see the disease take over the horses body.
Acid rain has been proven to have damage forests, fresh waters and soils, killing insect and aquatic life-forms. It also causes damage to buildings and impacts on human health. Many people do not know what acid rain actually is. Acid rain is any form of precipitation that is unusually acidic, low pH levels, higher than normal amounts of sulfuric and nitric acid, occurs naturally and from man made sources. Forms when gases react in the atmosphere with water, oxygen, and other chemicals (what is acid rain?). The only water that will not have some amount of acidity is pure water. Pure water has a pH of 7 which is neutral; regular, unpolluted rain water has a pH of around 5.6. The acidity in rain water comes from the presence of Carbon Dioxide, Nitrogen Oxide, and Sulfur Dioxide. CO2 reacts with water to form carbonic acid. Nitrogen and water react during lightning storms, forming Nitric Oxide. NO is then oxidized to form N02. The NO2 reacts with water to form nitric acid. Due to this, the pH is lowered to be slightly acidic (Acid Rain). Acid rain can occur naturally in the environment, but the problem occurs when human interaction is the cause of the acidic levels.
Storm waters are widely used in many different areas, even required in some. They are a vital tool that helps keep streams healthy. Storm water ponds are used to capture, control, and filter all kinds of runoff that could be from anything like parking lots to roof tops. The use of storm water ponds is essential to slow the flow of water down, filter out toxins, and improve the health of streams for aquatic life and for consumption purposes. All of that is in efforts to protect local streams.
Have you ever wondered why little rain can cause drastic floods? Why rainwater doesn't just stay in one place, it goes with the force of gravity? If you have, you’ve thought about a cycle called runoff. Runoff can be negative and positive. It can cause floods, or water your crops.
...ds, which allow us to grow using between 50% and 90% less water than a comparable farm not practicing recirculation. Since we recirculate 100% of irrigation water, our greenhouses don't load the municipal drainage system and our plant nutrients don't end up in lakes and rivers.” If more cities use this method then we will have more water, which can be used to grow more crops to feed the world!

Water is one of the most essential non-renewable natural resources on the Earth. Technically, an un-hydrated human being can live no more than three days. In the United States, people consume water mainly from tap water and bottle water. However, the consumption between these two sources is not even but lean to one side heavily. According to the Natural Resources Defense Council, people consume from 240 to over 10000 times more per gallon for bottled water than they usually do for tap water. (NRDC) In addition, according to a survey from US National Library of Medicines, only 17% of the participants prefer to drink tap water exclusively.(US National Library) Compared to the bottled water which is shining like a superstar, tap water is like a diligent worker in the shade, unpopular but useful. The extremely unbalance of bottled water consumption implies that a commonly hold conception exists: bottle water is superior to tap water. In fact, scientific evidence proves that tap water is nothing different than bottle water. More importantly, the excessive consumption of bottled water is an irrational use of resources and creates severe environmental issues.
As of this year, nearly 1.1 billion people live without clean drinking water and 2.6 billion live without adequate water sanitation. The McDonald's down the street, however, will sell you a 1/3 pounder burger for only 150 gallons. Changes in lifestyle can easily reduce this number and help not only save water, but money as well. Currently, with our diminishing water supply, one of the main goals of humanitarian organizations is ensuring that everyone has the right and equality to water. With global access to water, it reduces the responsibility for political tension between countries fighting to literally stay alive.

Water scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need, causing them to die. This eventually affects the global population. Therefore, many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling. The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well, the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development.
