Water is the infrastructure for the development of various sectors, and it is one of the important components of maintaining, the balance and stability of the ecosystem and the environment. In Iran, limited available water, non-uniform distribution, and inappropriate patterns of water consumption, It has caused problems in the supply of water in many parts of the country. Because the purpose of this research is to prioritize the use of water supply sources, This ranking was determined based on the type of climate and building type and with the approach of reducing costs and reducing water consumption, Therefore, the identification of different sources of water supply was done based on Köppen-Geiger climate classification and 4 building types. The economic analysis of water supply resources per unit volume of water was evaluated in a thirty-year period. In this research, the profitability and investment return period in case of implementation and exploitation of each of the water supply sources Based on three different water prices, i.e. mineral water price, export water price, and government water price, was examined. The results show that the highest cost of implementation and operation belongs to the humidity methods and the lowest cost is related to the methods of purifying sea and ocean salt water with modern methods. It has been the most economic profit based on the price of mineral water and export water in modern saltwater purification methods, And it is based on the price of government water in the method of water supply through the surface and subsurface water, the lowest economic profitability is in water supply methods through humidity methods.
