In past centuries, given the low number of world population, the small size of communities and the prevailing
culture of consumption, the water problem as we know it today did not exist [1]. However, after industrialization, the
phenomenon of urbanization and the easier exploitation of the God given natural resources, the trend of erratic
consumption increased more and more and led to the appearance of numerous difficulties [2]. Consequently with the
increase of global population and the global warming, the search for new resources to reduce the use of natural
resources has become an inevitable necessity [3]. One efficient method of using water resources is their re-treatment
and reuse in sectors such as agriculture and landscaping [4]. This research studies the reuse of grey water as a
recyclable water resource. The per capita grey water production in different countries is shown in table 1.
