Feasibility studies and evaluations for the rehabilitation, construction, and operation of wastewater treatment plants (WWTP) within the Build-Operate-Transfer (BOT) model.
In this project, 4 Wastewater Treatment Plants (WWTP) have been selected, each with different municipalities and population scales. The first phase includes the preparation of feasibility reports that encompass the concept design and detailed estimates of the project cost (including capital and operating and maintenance expenses). In the second phase, financial analyses have been carried out to determine the net present value of the investment cost, cash flow, and tariff impact analyses, along with establishing a suitable Public-Private Partnership (PPP) structure for municipalities. The final phase includes the preparation of all necessary documents, agreements, and references required to complete the bidding process under the PPP model. Within the project: • Kocaeli Gölcük WWTP is designed with a capacity of 73,332 m³/day for the year 2032, 97,205 m³/day for the year 2042, and 130,278 m³/day for the year 2052. • Nevşehir Ürgüp WWTP is designed with a capacity of 11,520 m³/day for the year 2032, 14,338 m³/day for the year 2042, and 17,677 m³/day for the year 2052. • Capacity enhancement has been made for Kırıkkale Central WWTP, with a design flow rate of 51,976 m³/day for the year 2037 and 77,061 m³/day for the year 2052. • Capacity enhancement has been made for Kütahya Simav WWTP, with a projected treatment capacity of 7,815 m³/day for the year 2037 and 9,861 m³/day for the year 2052.
