The feasibility of different techniques for providing fresh water to Research Paper

The feasibility of distinct techniques for providing fresh pee to arid regions of the world - Research Paper ExampleTo make matters worse, the little urine received in these areas is usually not safe for domestic, agriculture and commercial use and there an imperative need to provide fresh pissing. To do so, policy makers explore various fresh water homework techniques as discussed in subsequent sections of this report. 2.0 Fresh water provision techniques In endeavors to provide fresh water to the arid regions of the world, different techniques are employed that include ground water applicationing, desalinization and piping techniques. These techniques oftentimes vary from those employed in areas where precipitation is high. Therefore, climatic conditions in arid regions dictate to a spectacular extent what technique(s) is most appropriate. Key issues in water provision and water resource management which dictate appropriate techniques will include availability of adequat e go forth, conservation measures, cost effectiveness, pricing and sustainability. 2.1 Ground water supply Drilling Technique Ground water is normally obtained from aquifers through drilling and piping the water to the come along for various uses. This technique involves identification of areas in arid regions that have sufficient and quality underground water for agriculture, domestic and commercial use. The technique is more preferred to its low cost of establishment compared to other techniques akin desalination. To ensure sustainable use of underground water, policy makers and regulatory authorities establishes water databases through adaption of wells and their yields, documenting water composition, control of drilling in all phases and regular monitoring of water bow and changes in salinity. However, the challenge with this technique is that over time demand for fresh water has attachd twain socially and economically requiring more wells to be dug. For example, over th e last 3 decades, demand for water within the United Arab Emirates and other Gulf states which are often classified as arid regions, was estimated to increase from 4,250Mm3/ year in 1980 to 35,395Mm3/ year by 2010 (Alsharhan et al 2001, 277). Therefore, this means that governments in arid regions have to drill more wells or explore alternative fresh water supply techniques. This water supply technique faces various challenges relating to quality and sustainability. One, underground water may contain dissolved solid substances whose abide by is above the established norm. Establishing these levels require sophisticated technology which is costly and often not at the garbage disposal of most governments in arid regions. Where levels are higher than the benchmark standard, such wells have to be closed or alternative technologies to reduce the hazardous effects of these particles employed (California Environmental Protection mission 1995, 5). For example, high fluoride levels are com mon in arid regions where fluoride levels have to be reduced to the World wellness Organization (WHO) to reduce effects of tooth decay and bone weakening. In addition, underground water
