Marmara Basin is the most developed basin of our country in terms of population and industrialization. The unplanned and uncontrolled development of industrialization has caused significant damage to natural resources, especially in İstanbul and Kocaeli. In İstanbul, all OIZs and industrial facilities are connected to the sewerage infrastructure. However, it can be stated herewith that the wastewater treatment facilities of many organized industrial zones and various industrial facilities are either not available at all or inadequate.
