The use of packed water in urban drinking water and its advantages to other methods of separating drinking water from undrinkable water (the case study : Ferdows city in South Khorasan)

Today, more than one billion people of the world don't have access to safe drinking water. Therefore, due to the population increase and consequently increasing water needs, and the reduction of drinking water sources available, separating drinking water and non-drinking water seems necessary. In this article, the use of packed water is compared to other methods, such as two networks (drinkable and non-drinkable) water supply, public water stations, purifying drinking water, and transferring high quality water from distant areas. Some statistics and information about the cities of Birjand, Ferdows for statistical analysis are used. Most scientists believe that changing the world weather is because of the greenhouse effect, which has had many harmful effects on the planet. With the increasing of the use of fossil fuels and accumulation of pollutant gases in the atmosphere of the earth which are the results of spreading industries and cars in the recent centuries, the greenhouse effect has occurred that the heat and returning long waves can't go out of the atmosphere, and consequently the earth temperature has increased. The increasing temperature phenomenon then would be a sign of a trend to a drier climate.
