Blue Flag’s 30th Anniversary in Kocaeli Municipality, Türkiye - Mud Removal Project - Best Practice Field Trip

During the event, attendees visited one of the initiatives known as "Cleaning, Dewatering, and Disposal Service of Izmit Gulf's East Basin Bottom Sludge" project. This initiative, backed by the Presidency's Strategy and Budget Department, aims to protect the Gulf of Izmit's environment. Led by the Ministry of Environment, Urbanization, and Climate Change and the Kocaeli Metropolitan Municipality, it targets clearing bottom mud in the Gulf's eastern basin to improve the area's environment. Additionally, Kocaeli Municipality, in partnership with TÜBITAK, MAM, and Istanbul University, is conducting thorough studies on the accumulated bottom mud, studying currents, surface water, and human activities in the region.

The research findings highlight the significant role of accumulated bottom mud in generating unpleasant odors and increased turbidity, especially during meteorological occurrences like southwesterly winds. This sediment obstructs water circulation, triggering detrimental effects such as algal blooms and a reduction in dissolved oxygen levels, creating an inhospitable environment for the marine ecosystem.  Notably, the study establishes a direct correlation between the bottom mud and the formation of mucilage in the Marmara Sea, adversely impacting the overall ecosystem.

The launch of a specialized project marks a crucial milestone in the restoration efforts for the Izmit Gulf, with far-reaching implications for the entire Marmara region, a vital Mediterranean corridor. This ambitious two-stage initiative aims to cleanse around 720 million tons of bottom mud across an extensive 8.5-hectare area. Upon the successful completion of the second phase, Izmit Bay will be ready for regeneration, planned to resemble a "giant aquarium," reflecting its pristine state from earlier times.

The implementation of the project involves the meticulous removal of sludge from the seabed through specialized pipes, facilitating its transportation to a designated "dewatering facility" situated behind the Izmit Athletics Track. The comprehensive endeavor is slated for completion over a five-year timeline, underscoring a dedicated commitment to environmental restoration and sustainable marine practices.
