چکیده

آب زیرساخت توسعۀ بخش‌های مختلف بوده و از مؤلفه‌های مهم در حفظ، تعادل و پایداری اکوسیستم و محیط زیست است و در ایران، محدودیت آب قابل دسترس، توزیع غیر یکنواخت و الگوی نامناسب استفاده، تأمین آب مورد نیاز را در بسیاری از مناطق کشور مشکل ساخته است. با توجه به اینکه هدف این تحقیق اولویت‌بندی استفاده از منابع تأمین آب است و از طرفی، این اولویت‌بندی براساس نوع اقلیم و تیپ ساختمانی و با رویکرد کاهش هزینه و کاهش مصرف آب تعیین شد، لذا شناسایی منابع مختلف تأمین آب براساس دسته‌بندی اقلیمی کوپن‌ـ گیگر و 4 تیپ ساختمانی انجام شد. تحلیل اقتصادی منابع تأمین آب به ازای حجم واحد آب در یک دورۀ سی‌ساله مورد ارزیابی قرار گرفت. در این تحقیق سودآوری و دورۀ بازگشت سرمایه در صورت اجرا و بهره‌برداری هر یک از منابع تأمین آب بر مبنای سه قیمت مختلف آب یعنی قیمت آب معدنی، قیمت آب صادراتی و قیمت آب دولتی بررسی شد. نتایج نشان می‌دهد بیشترین هزینۀ اجرایی و بهره‌برداری متعلق به روش‏های رطوبتی و کمترین هزینۀ مربوط به روش‏های تصفیۀ آب شور دریا و اقیانوس با روش‏های نوین بوده است. بیشترین سوددهی اقتصادی بر مبنای قیمت آب معدنی و آب صادراتی در روش‏های نوین تصفیۀ آب شور بوده و بر مبنای قیمت آب دولتی نیز در روش تأمین آب از طریق آب سطحی و زیرسطحی است و کمترین سوددهی اقتصادی نیز در روش‏های تأمین آب از طریق روش‏های رطوبتی است.

چکیده [English]

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.
