Abstract

With increasing population, reducing the per capita amount of water resources and increasing the physical, chemical and microbial contamination of water, water crisis is one of the major global problems. The purpose of this study is to examine the use of dual system for rural communities in Ferdows city. The study options include the installation of desalination water with a separate network, the establishment of fixed tanks in the villages and water supply by mobile tankers, alley-to-alley traffic, and the use of mobile tankers or routine methods, the transfer of drinking water through the creation of a dual network in the village And the construction of water harvesting platforms, supply of drinking water by the construction of an industrial sweetener plant and the connection to the village distribution network and Use Freshwater Cards Sales Economically and risky, the study was prioritized. According to the results, the cost of supplying drinking water by Use Freshwater Cards Sales per cubic meter is 8000 Rial, but with a mean risk of 20.33, it has the highest risk among the options. The transfer of drinking water through the creation of a dual network in the village economically, at a cost of 15000 Rial, is the second economic priority, with a mean risk of 6.5% with the lowest risk which can be considered as a priority for integrated water supply, given its economic status.  Due to regional climate change and frequent droughts, creating a dual network is the most effective way to deal with problems.
