The Need and Implementation of Wastewater Usage Introduction Water is one of the most abundant substances on Earth, but the vast majority of it cannot be used for human or industrial use because of the salt content. With cost effective desalination processes several years away, we are limited to fresh water resources such as lakes, reservoirs, and aquifers, but these resources, in many areas, are being used drained at rates faster than they can replenish, or are too difficult to reach. Agriculture is one of the primary users of wastewater, as the Food and Agriculture Organization of the United Nations(FAO) points out in their publication “The Wealth of Waste: The Economics of Wastewater Use in Agriculture”. This is why the agriculture…show more content…
2). How little water is available for a population of seven billion people inhabiting this planet is staggering and a little frightening. To compound the problem, “[m]ost fresh water is remote from civilization or too difficult to capture for use”(Winnpenny et al, pg. 2). Also the average person may not consider fresh water for anything other than consumption or cleaning, but that is simply not the case as this reports points out. “Water is essential not only for direct human consumption and household purposes, but also for producing the food and manufactured goods necessary for life and improved standards of living”(Winpenny, et al, pg. 2). With all these concerns in mind, a good argument for recycling wastewater can be made. The Current Practice of Wastewater Reuse At the time of the publication of “The Wealth of Waste: The Economics of Wastewater Use in Agriculture”, there were over 3,300 water reclamation facilities in the world, with the vast majority in the United States and Japan(Winnpenny et al, pg. 11). There are also several hundred spanning every continent sans Antarctica. All of these facilities are reclaiming wastewater for various uses including human consumption, recreation, irrigation, and other industries. “In Europe, most of the reuse schemes are located in the coastal areas and islands of the semi-arid Mediterranean regions and in highly urbanized areas”(Winnpenny et al, pg. 13). The location of these
