Facing climate change through the expected temperature increase by 2.5-4 degrees in the coming years and drought, Turkish authorities predicted that the annual water potential per person will to to 1.120 m3 in 2030.  It became probable for Turkey to be included in the list of countries experiencing water shortage in the near future. So, it became necessary to develop practices based on strategies related with the economic and planned use of the available water sources in fighting with the water shortage problem that will emerge before us in the future. From these strategies, the option for the re-use of waste waters emerges as one of the most important methods used in the economic use of water.

This project is intended to examine and assess alternatives aimed for the re-use of the waters used in homes, industry, tourism, energy generation and agriculture in Turkey.


    1. The waste water potential in our country will be revealed in light of the previously conducted studies and current data to be collected from the institutions and organizations.
    2. The characterization of the waste waters in the country in general will be demonstrated on catchment basin basis.
    3. The “potential areas (agriculture, industry, tourism, etc.) for the re-use” of waste waters on catchment basin basis and “places for waste water storage” on regional basis will be determined for the country in general.
    4. The re-use practices in the world countries will be examined with respect to capacity and techniques, the status of the re-use practices in Turkey will be revealed, the re-use criteria for our country and the necessary treatment processes for treating waste water will be determined, and a re-use action plan draft will be prepared.
    5. The re-use practices will be examined from the technical perspective, and a guidance document providing information on the modes of application will be prepared so as to serve as a guide for the related institutions.
    6. The benefits and risks of the re-use practices will be demonstrated.
    7. The cost analysis (including collection, treatment and transmission costs) of the re-use practices will be made.
    8. The re-use capacity will be determined in two pilot provinces to be selected, feasibility study will be carried out so as to assess various use alternatives, and an implementation project will be prepared for the treatment process and transmission lines necessary for the re-use of waste water output by the largest treatment plant of the city.
    9. An internet website and public service announcement will be prepared for the project.
    10. It will be ensured that a database is formed for the data acquired in the project and this database is integrated with the National Water Information System (NWIS).
    11. Training, workshop and awareness increasing studies will be carried out concerning the project outputs.
    12. General assessment studies will be conducted.
