Throughout the world, providing drinking water via desalination engineering becomes a more and more adopted option. With quickly progressing desalination engineering and market maturation, desalination prices are fast dropping, and the ecological effects of desalination are steadily relieved. Even if desalination is probably to stay more costly in nearly all areas than conventional water provision solutions, it could turn into progressively a solution to satisfy inevitable deficiencies for particular markets. Consequently, desalination has to be employed strategically inside a combined water-planning program. This work discusses desalination as a practicable option to reduce a water provision-need vacuum and its techniques and features. Ecological duties should force a huge extension of used water gathering and handling; further, increasing water shortage and prices could render used water reuse growingly a profitable solution. Nontraditional solutions like wastewater reuse and desalination have to be considered jointly to deal with water shortage. Improving adopted technologies and increasing allocated funds to these future and indispensable nontraditional solutions remain unavoidable. Secured technologies like membrane processes should be largely applied throughout the world to secure potable water for all humankind.
