Project Description

The Baku Water Desalination Project (the “Project”) represents part of Azerbaijan’s strategic response to water security and is designed to provide new or improved reliable water access to estimated 1.5 million people. To support this IFC is considering a senior loan towards the construction and operation of a 300,000 m3/day Seawater Reverse Osmosis (SWRO) desalination plant in Sumgayit Chemical Industrial Park, in the Republic of Azerbaijan (the "Project"). The Project is to be developed by Caspian Sea Azerbaijan Project Company LLC (“the Company”), a special purpose vehicle (SPV) established by ACWA (“the Sponsor”), a Saudi-based independent power and desalination company. More information about the Sponsor can be found at www.acwapower.com. The Project is a brownfield development utilizing a former wastewater treatment plant area, and consists of the design, construction, financing, operation and maintenance of a SWRO desalination plant, which will supply potable water to United Water Supply Service of Large Cities (UWSSLC), the off taker.

The Project consists of marine works in the Caspian Sea and an onshore desalination plant. The marine works include a 2 m diameter 3,475 m offshore seawater intake pipelines which will supply water to the desalination plant, and a 1.2 m diameter 2,000 m brine outfall pipeline through which the brine resulting from the desalination will be returned to the Caspian Sea. The desalination plant to be constructed within the Sumgayit Industrial Park comprises a pre-treatment system, reverse osmosis system, post treatment facilities, and product water storage and ancillary facilities. Power for the Project will be delivered from a planned substation to be built by Azerishyg OJSC connected to Azerishyg’s existing adjacent overhead powerline running within 100 m of the Project. Potable water generated by the Project will be delivered to the water distribution system via a 15 km 1.6 m diameter pipeline which will be designed, constructed, operated, and maintained by the Azerbaijan State Water Resources Agency (ADSEA), its owner, and will be installed underground within a legally defined 20 m protection corridor. The alignment has been designed to follow, where practicable, existing infrastructure corridors within the Sumgayit Industrial Park and ADSEA utility corridors, avoiding residential areas and environmentally sensitive receptors. Both the substation, short OHTL, and pipeline are associated facilities (AFs). During Project construction, material will be delivered from external sources, and concrete will be delivered from an offsite facility, any localized areas of contaminated soil resulting from the previous industrial uses of the brownfield site which are required to be removed from the site as part of the construction will be disposed of to local licensed landfills.

Overview of IFC's Scope of Review

IFC's appraisal of this proposed investment took place from October 2025 to May 2026 and was supported by an Independent Lenders’ Environmental and Social Advisor (“LESC”). The appraisal included: (i) a desktop review of available information; (ii) virtual and face to face meetings with the Project team including technical and Environmental and Social (E&S) staff; (iii) a site visit that included the proposed locations for the marine infrastructure, the desalination plant and the proposed routing of the water conveyance system. Documentation reviewed included an Environmental and Social Impact Assessment (ESIA), a Stakeholder Engagement Plan (SEP), selected draft ESMS documents, and an Environmental and Social Management System Implementation Manual produced by the Company.
