GOSB Central Wastewater Treatment Plant Project Feasibility Report, Preparation of Tender Documents and Consultancy Work

The project involves conducting technical, economic, and administrative studies for the establishment of a central wastewater treatment plant needed by the Gebze Organized Industrial Zone (GOSB). Within the scope of the study, the ‘build-operate-transfer’ and ‘turnkey fixed-price’ tender models have been technically evaluated; analyses of water consumption, wastewater characterization, and pre-treatment needs have been conducted based on up-to-date information collected from the OIZ participants. During the project process, alternative treatment technologies were examined, wastewater recovery opportunities were evaluated, design parameters for the plant were determined, and a feasibility report including all technical, economic, and environmental analyses was prepared. Additionally, technical documents to be used in the tender process were created; bids were received, evaluated from a technical and financial perspective, and consultancy support was provided to determine their compliance.

Within the scope of this project, the following services have been provided by our personnel:

  • Technical evaluation of “Build-Operate-Transfer” and “turnkey fixed-price” models,

  • Collection and analysis of data regarding water consumption and wastewater characterization from GOSB participants,
