Wang et al. (2007) affirm that populated arid and semi-arid areas occupy approximately 30% of the total global land area and that water shortages are a major stumbling block to social and economic development in these regions. In the supply of freshwater to the arid regions of the world, rationality and fairness should prevail. In the rational distribution of water resources, a balance between demand and supply must be considered together with other factors as annual rainfall distribution as well as various economic sectors in a region (Wang et al., 2007, p. 2). The fairness and efficiency of freshwater distribution are overriding principles in arid areas. A dynamic model for equitable provision of freshwater in arid regions is a pivotal measure towards the eradication of misfortunes that result from the absence of water in the human residence.&nbsp.

The options as follows:Recycling of wastewater.Transportation of water over a long distance in pipes.Harvesting groundwater using boreholes.Desalination&nbsp.

Mays (2009) reveals that wastewater collection (sewage) can be treated for human consumption. He argues that under particular specifications sewage water could be made safe for consumption. however little there is in the arid and semi-arid areas. The water treatment process is a biological process that takes place in water treatment plants. As much as this water is scientifically proven to be safe for human consumption, it is normally hard to convince consumers that it is 100% safe due to their disturbed minds regarding the source of the water (Stephenson et al., 2004). With a close reference to the National Academy of Science (2001), there are challenges associated with the recycling of wastewater, especially in the part of decision making and implementation.
