Sources: 19. Developments: 2. Turkey is undertaking significant water infrastructure and wastewater treatment upgrades across several major regions to address pollution and long-term water security. In the İzmir and Istanbul regions, efforts are focused on combating an ‘ecological crisis’ caused by industrial waste. In İzmir, officials have identified heavy metals such as lead, mercury, and aluminum in the İzmir Gulf, prompting a 976 million TL investment to modernize the Çiğli Advanced Biological Wastewater Treatment Plant. In Istanbul, the goal is to ensure all wastewater discharged into the Marmara Sea undergoes advanced biological treatment by expanding the capacity of the Ambarlı plant. In the capital, the Ankara Metropolitan Municipality has secured approximately $500 million in international financing for projects aligned with the 2054 Ankara Master Plan. These investments include expanding the capacity of the Ankara Central (Tatlar) Wastewater Treatment Plant, developing drinking water supplies in several surrounding regions, and implementing measures to reduce water loss and leakage throughout the metropolitan area. ## Timeline ### 2026-08-20: Ankara secures $500 million for major water infrastructure projects Ankara has secured $500 million in international financing for three major water infrastructure projects to improve wastewater treatment, drinking water supply, and reduce water loss by 2054. 5 sources. https://clstr.news/cluster/ankara-secures-500-million-for-major-water-infrastructure-projects ### 2026-08-14: Turkey implements major wastewater infrastructure upgrades to combat pollution Turkish authorities are tackling water pollution through major infrastructure projects in İzmir and Istanbul, targeting industrial waste in the Gediz River and upgrading wastewater treatment for the Marmara Sea 16 sources. https://clstr.news/cluster/gediz-river-industrial-waste-pollutes-izmir-gulf --- Cite as: Turkey water infrastructure and wastewater upgrades.
