BACKGROUNDIFC is collaborating with the Ankara Water and Sewerage Administration (¡°ASKI¡± or ¡°the Client¡±) regarding the financing of the capacity expansion and treatment methodology upgrade of the Tatlar Wastewater Treatment Plant (¡°the Project¡±). Located in T¨¹rkiye¡¯s capital and second largest city; Ankara; Tatlar WWTP is the main wastewater treatment plant serving the central districts where 90% of the population lives and several industrial zones are located. Due to aging infrastructure and increasing utilization driven by rapid population growth; Tatlar WWTP was no longer able to process all the incoming sewage; resulting in a 40-45% of the wastewater being discharged directly into local stream. With the planned expansion; Tatlar WWTP will be able to serve Ankara¡¯s projected population of 6.8 million by 2040; avoiding the environmental and health risks connected to the discharge of untreated wastewater in nearby basins. Tatlar WWTP has been operating since 1997; with a design capacity of 765;000m3/day based on the anticipated population of 3.3 million in 2002; it can operate today at approximately 60% capacity utilization factor only. Furthermore; as the current design only removes carbon; the remaining nutrients are left untreated in the process. Both result in significant problems in terms of the quality of water discharged into Ankara Stream; which feeds into Sakarya river basin; and ultimately potable water sources of many cities in Marmara region including Istanbul.With this project; the Tatlar WWTP will be upgraded into an advanced biological wastewater treatment; with enhanced capacity of 1;350;000m3/day (adding 585;000m3/day). The capacity expansion and upgrade of the Tatlar WWTP is also expected to improve environmental sustainability and resilience to climate change. By enhancing the plant's capacity and upgrading its technology; the Project can better manage and treat wastewater generated in the Ankara metropolitan region; reducing pollution and greenhouse gas emissions. A reduction of 20;420 tCO2e per year is expected (to be confirmed). ASKI is a member of IFC¡¯s Utilities for Climate (U4C) network that supports emerging market utilities find climate-friendly solutions to their challenges through investment and advisory services; and providing access to a global knowledge network among peer utilities. Main objectives of the consultant¡¯s missionThe project realizes significant emissions reduction; which could be monetized on the Voluntary Carbon Market (VCM). The consultant¡¯s mission is to support ASKI and IFC in assessing and identifying opportunities to generate verified carbon credits related to the GHG emissions brought by the rehabilitation and extension of a WWTP under credible methodologies / standards; leading carbon credits certification issuance process for ASKI to obtain verified carbon credits; and conducting demand analysis; identifying potential buyers of carbon credits and assisting ASKI to establish the sales strategy of carbon credits.These Terms of Reference lay out the main role of the consultant; which is to provide a list of instructions for generating and selling carbon credits related to the ASKI WWTP project according to the three main phases below. This procurement is only for Phase 1; but the selected firm must show experience and capabilities to conduct phases 2 and 3 as well. PHASE 1 ¨C Assessment and identification of opportunities to generate carbon credits related to the capacity expansion and upgrading of the Tatlar WWTP under credible methodologies / standards. (The first phase is expected to last 4 months).PHASE 2 ¨C Carbon credits certification and issuance. (This phase will last around 1 year ). PHASE 3 ¨C Assistance and capacity building to ASKI in assessing the demand; identifying potential buyers and establishing sales strategy to sell carbon credits on the Voluntary Market. (This phase is expected to last 1 year; IFC¡¯s assistance is limited to the first issuance of carbon credits).Detailed scope of work is outlined in the TOR attached.
