Abstract

According to the forecast of future population growth and recent droughts in the country, one of the major challenges for policymakers on the one hand is to provide safe drinking water and on the other hand, is to solve environmental and health problems caused by undesirable wastewater disposal. To solve this problem in Mashhad, the regional water company of Khorasan Razavi and the water and wastewater company of Mashhad in multilateral cooperation have developed an effluent model to construct a wastewater treatment plant, water supply, and effluent recycling. In this model, due to the lack of public budget and internal resources of companies, the use of private capital by transferring wastewater to the investor to achieve environmental goals and water supply in Mashhad, which has significant benefits for the private sector and community is defined. In this model, two investment packages have been developed between the two companies, the details of which are discussed in the paper. What is very important in this project is to achieve a sustainable effluent model for achieving the defined goals. In this investment model, a total of 93% of water needs and 29% of the required capacity for wastewater treatment will be provided.
