Saudi Arabia holds sewerage plant site visits

30 January 2025

 

Representatives from more than 20 firms participated in the site visits conducted by Saudi Water Partnership Company (SWPC) for two upcoming independent sewage treatment plant (ISTP) projects in the kingdom.

SWPC conducted the site visits on 28 January, according to a source familiar with the projects.

Located in Mecca, the first scheme, the Arana ISTP, will have an initial capacity of 250,000 cubic metres a day (cm/d), expandable to 500,000 cm/d.

The second scheme, the Hadda ISTP, will also be located in Mecca and will have an initial capacity of 100,000 cm/d, expandable to 250,000 cm/d.  

SWPC expects to receive bids for the contracts by 5 May. However, the bid deadline is likely to be extended until the early summer, the source said.

Expected to be operational by 2028, both projects will be implemented using a 25-year build, own, operate and transfer model.

They also include treated sewage effluent (TSE) reuse systems consisting of transmission pipelines and TSE tanks.

In March last year, SWPC signed a 25-year water-purchase agreement with a team comprising the local Miahona Company and Belgium’s Besix for the contract to develop and operate the proposed Al-Haer ISTP in Riyadh, as part of the third batch of the kingdom’s ISTP programme.

The Miahona/Besix team offered to develop the project for SR1.9407 ($0.5173) a cubic metre, while the second-lowest bid, from a team comprising Spain’s Acciona and the local Tawzea, was SR2.2041 a cubic metre.

The Al-Haer ISTP project involves the development of a water treatment plant with a capacity of 200,000 cm/d.

It also includes developing a TSE reuse system that covers a 32-kilometre pipeline with a capacity of 400,000 cm/d, a pumping station and TSE reservoir tanks with a capacity of 200,000 cubic metres.

  • Taqa raises $750m to finance water projects

    30 July 2026

    Abu Dhabi National Energy Company (Taqa) has issued a $750m five-year blue bond to finance sustainable water and wastewater management projects.

    The company said the transaction is the largest blue bond issuance in the Europe, Middle East and Africa region. It is also the largest blue bond issued by an integrated power and water utility globally.

    Issuing the bond allows Taqa to raise money from investors specifically to support water-related environmental projects. These can include desalination, wastewater treatment, water recycling and reuse, and infrastructure that improves water efficiency.

    It is the first blue bond issued under Taqa’s Green and Blue Finance Framework, and follows another blue financing transaction in the UAE earlier this year.

    On 8 January, Dubai-based Emirates NBD bank announced the completion of a $1bn dual-tranche sustainable bond issuance, comprising a $300m blue tranche with a three-year tenor and a $700m green tranche with a five-year tenor.

    Emirates NBD said at the time that the $300m tranche was the largest blue bond issued in the UAE and GCC. The proceeds are intended to support marine conservation and sustainable water projects, while proceeds from the green tranche will finance green initiatives.

    Taqa launched its original Green Finance Framework in 2023 and updated it in 2026 to include blue financing instruments. The latest issuance takes its total green and blue labelled bond issuances to $2.6bn since 2023.

    The Taqa financing also comes as the company expands and modernises its water infrastructure. Taqa is targeting reverse-osmosis technology for 66% of its desalination capacity by 2030, up from about 40% in 2025.

    In June, Taqa awarded a contract for the construction of a 1-million-cubic-metre emergency lagoon in Abu Dhabi. The project will be developed in two phases.

    Phase one has a capacity of 500,000 cubic metres and is planned to be completed within 18 months of the contract award.

  • UAE renewables firm secures $375m in financing

    30 July 2026

    Positive Zero, the UAE-based renewable energy firm, has announced the successful closing of a financing facility of up to $375m.

    The long-term financing was arranged by Paris-headquartered Natixis Corporate & Investment Banking (Natixis CIB) and Saudi Arabia-based The Arab Energy Fund.

    Natixis CIB also acted as financial adviser, facility agent, security agent and green loan coordinator for the transaction.

    “The non-recourse financing is the first transaction of its kind in the region for a diversified portfolio of decentralised infrastructure assets, including distributed solar power generation, energy efficiency and clean mobility solutions,” Positive Zero said in a statement.

    “The financing will provide substantial long-term capital to support Positive Zero’s continued expansion in the United Arab Emirates, Saudi Arabia, Bahrain, Oman and Qatar, funding the growth of its distributed infrastructure portfolio, capital expenditure programme and strategic development initiatives,” the Dubai-based firm said.

    The new debt facility secured by Positive Zero builds on US-based BlackRock’s investment of up to $400m in the company in 2023, “further strengthening the company’s capital structure and supporting the next phase of its growth”.

    Positive Zero has the largest distributed solar capacity in the region with more than 500MW in operations and under construction, avoiding more than 450,000 metric tonnes a year of carbon emissions.

    The company has also saved over 100 million kilowatt-hours (kWh) in energy consumption across its client portfolio through its energy-efficiency solutions.

  • US-Saudi consortium to build $5bn refinery outside Strait of Hormuz

    30 July 2026

    Register for MEED’s 14-day trial access 

    A consortium of privately owned US and Saudi companies has announced an investment commitment of $5bn to build an integrated oil refining, storage and export facility outside the volatile Strait of Hormuz shipping lane.

    After three years of evaluating sites across the Gulf, the consortium has shortlisted three GCC locations beyond the Strait of Hormuz. Discussions have advanced over the past two years, with a preferred site expected to be selected by the end of 2026.

    The consortium, Mera Oil, comprises Fort Worth, Texas-based MWG Enterprises; the US-based Patel Family Office; and PWS, an associate company of Saudi Arabia’s AHQ Group.

    Mera Oil said it remains open to alternative proposals that meet its infrastructure, resilience and development requirements.

    The proposed project will feature a 200,000-barrel-a-day refinery, deepwater port connectivity, large-scale crude and refined-product storage, and marine export facilities.

    A pre-feasibility study covering refinery design, logistics, capital requirements and execution planning is at an advanced stage.

    Once a host jurisdiction is confirmed, the project will proceed to detailed site assessments and engineering design, with mechanical completion targeted for end-2029, followed by commissioning and the start of commercial operations.

    The consortium plans to focus on producing high-specification middle distillates, including ultra-low sulphur diesel and jet fuel, for selected international markets.

    The project is expected to occupy about 1,200-1,500 acres of port-connected industrial land and could create up to 3,000 direct jobs, and around 15,000 indirect and induced jobs, during construction and operations.

    Mera Oil is also progressing discussions with feedstock suppliers and expects financing to include sponsor equity, sovereign and institutional investment, project finance, export-credit support and sharia-compliant funding structures.

    “Designed as a route-resilient energy hub, the development aims to strengthen regional manufacturing, logistics, technical expertise and energy security,” Mera Oil said.

    The first phase of the planned investment will “incorporate energy-efficient refining technologies, emissions-control systems, and potential future capabilities including sustainable aviation fuel co-processing and carbon management.”

  • Local contractor to build nine Bahrain substations

    30 July 2026

     

    Bahrain’s Electricity & Water Authority (EWA) has awarded the local Al-Kooheji Electrical a contract to build nine 66kV substations across the kingdom, according to a source.

    The project is estimated to be worth $110m and is intended to support rising electricity demand from Bahrain’s domestic, commercial and industrial sectors.

    Four local contractors submitted commercial bids for the contract in January. The bidders were:

    • Nass Contracting ($28.4m)
    • Poullaides Construction Company ($31.7m)
    • Mohammed Jalal Contracting ($32.4m)
    • Al-Kooheji Electrical ($34m)

    The substations will be located at South Hidd Industrial, Mondelez, Alba Downstream Park, Muharraq North, Hamala West, Bani Jamra, Hoora, Maqabah East and West Riffa Club.

    The scope includes the construction of the nine substations and control rooms, as well as the installation of transformers, switchgear and feeders connecting the facilities to the grid.

    It also covers communication cabling, monitoring systems, safety and security systems, and associated civil and structural works.

    As MEED understands, the substations are scheduled to be commissioned in stages. Two are planned for 2026, followed by four in 2027 and the remaining three in 2028.

    Serbia’s Energoprojekt Entel was appointed as consultant for the project in April 2025. The consultant’s contract was valued at about $460,000.
