problems emanating from the river, Ankara Metropolitan Municipality assigned the ASKİ (Ankara Water and Canalization Administration) the task to plan a clean-up project in 2006, which will connect the river with the sewage system. All the water will be directed to the sewage system, the river will be covered completely in certain locations, and the only water left running through the river will be that of any precipitation. The plan will also eliminate the polluted irrigation problem downstream since the river itself will be dried up. The project is scheduled to be completed in 2020.
