Dubai seeks EPC firms for $22bn tunnels project

8 February 2024

 

Register for MEED's guest programme 

Dubai Municipality has invited engineering, procurement and construction (EPC) companies to prequalify for the contracts to be procured under the multibillion-dollar Dubai Strategic Sewerage Tunnels (DSST) project

The project aims to convert Dubai's existing sewerage system from a pumped system to a gravity system by decommissioning the existing pump stations and providing "a sustainable, innovative, reliable service for future generations".

Dubai Municipality has requested interested companies to submit their statements of qualifications by 26 February, according to an industry source.

It expects to announce the prequalified EPC contractors by 11 March, following which it plans to start the prequalification process for the public-private partnership (PPP) consortiums that can bid for the project.

Dubai is currently served by two major sewerage catchments. The first, located in Deira, is called Warsan, where the flow is treated by the existing Warsan sewage treatment plant (STP).

The second catchment, called Jebel Ali, is in Bur Dubai, where the wastewater is treated at the Jebel Ali STP.

The DSST project is broken down into six packages, which will be tendered separately.

The first package, J1, comprises Jebel Ali tunnels (North) and terminal pump stations (TPS). The tunnels are to extend approximately 42 kilometres with the links extending 10km. 

The second package, J2, covers the southern section of the Jebel Ali tunnels, which will extend 16km, with a link stretching 46km.

W for Warsan, the third package, comprises 16km of tunnels, TPS and 46km of links.

J3, the fourth package, comprises 129km of links, which will be operated by the Dubai Municipality once completed, unlike the first three packages, which are envisaged to be operated and maintained by the winning PPP contractors.  

J1, J2 and W will be procured under a design-build-finance-operate-maintain model with a concession period expected to be between 25 and 35 years.

J3 will be procured under a design-build-finance model with a concession period ranging between 25 and 35 years.

J1, J2, W and J3 will comprise the deep sewerage tunnels, links and TPS (DLT) components of the overall project.

Meed understands the remaining two packages of the project, the expansion and upgrade of the Jebel Ali and Warsan STPs, will be procured in a process separate from the four DSST-DLT components of the project.

The requests for proposals (RFPs) for the four DSST-DLT packages are likely to be issued in sequential order on a staggered basis around six to 12 months apart.

According to the prequalification document, the bidders for each of the PPP RFPs will be prequalified consortiums comprised of sponsors, EPC contractors and operation and management (O&M) contractors.

Dubai’s Executive Council approved the DSST project in June 2023 and said it would require an investment of about AED80bn ($22bn).

The Council said that the project has been designed to serve the needs of the Dubai population for the next 100 years in alignment with the Dubai Economic Agenda D33 and the Dubai Urban Plan 2040.

Dubai Municipality appointed advisers for the overall scheme last year. It selected Abu Dhabi-headquartered Tribe Infrastructure Group as lead and financial adviser, UK-based Ashurst as legal adviser and the US' Parsons as technical adviser.

  • Iraq solar package on track to come online in December

    9 September 2026

     

    The 1,000MW solar photovoltaic project in Artawi – also called Ratawi – in southern Iraq is on track for its second phase to come online on 8 December, according to industry sources.

    This phase has a capacity of 250MW and will bring the project’s total online capacity to 500MW.

    The first phase of the project, also with a capacity of 250MW, came online in March this year.

    The third and fourth phases, each with a capacity of 250MW, are expected to be brought online next year.

    The solar project is part of the broader Gas Growth Integrated Project (GGIP), which has an estimated total value of $27bn and a first phase worth an estimated $10bn.

    The solar project’s ownership differs from the headline GGIP ownership structure, with its ownership equally divided between France’s TotalEnergies and QatarEnergy.

    The wider GGIP consortium includes TotalEnergies, Iraq’s Basra Oil Company and QatarEnergy, which hold stakes of 45%, 30% and 25%, respectively.

    China Energy Engineering Corporation is part of a consortium that is executing the main engineering, procurement and construction contract for the project.

    It announced that the first 250MW of capacity had been connected to the grid on 4 March this year.

    The consortium also includes China Energy Engineering Group Tianjin Electric Power Construction Company and Chengdu-headquartered Southwest Electric Power Design Institute Company.

    The project scope includes:

    • Construction of a substation
    • Installation of a 132kV booster station
    • Installation of solar panels
    • Installation of transformers
    • Laying of transmission lines
    • Construction of related infrastructure

    In February 2025, Basra Investment Commission director Alaa Abdul Hussein said the solar plant had an estimated total value of $820m.

    The GGIP programme is focused on developing four major projects in Iraq:

    • The Common Seawater Supply Project (CSSP)
    • The Ratawi gas processing complex
    • The 1GW solar power project for Iraq’s electricity ministry
    • A field development project at Ratawi, known as the Associated Gas Upstream Project (AGUP)

    All four of these projects are currently under execution, though there have been some delays related to the regional war that started when the US and Israel attacked Iran on 28 February.

    The conflict has caused significant disruption to shipping through the Strait of Hormuz, which Iraq uses to export crude oil and import equipment and materials for projects.

  • Saudi water sector hits sharp slowdown

    8 September 2026

     

    Saudi Arabia’s water sector has recorded a sharp slowdown in contract awards this year, with $3.94bn of new contracts awarded as of early September.

    According to regional project tracker MEED Projects, this is well below the $10.7bn recorded in 2025, $13bn in 2024 and a record $15.3bn in 2023.

    The slowdown comes as several major projects remain in the procurement process, with some yet to reach financial close or contract award, while tender deadlines for other schemes have been pushed back.

    Among the largest is the estimated $2bn Riyadh-Qassim independent water transmission pipeline. The 859-kilometre project will have a transmission capacity of 685,000 cubic metres a day (cm/d). Vision Invest was selected as the preferred bidder last December; however, more than eight months later, an official developer’s agreement has not yet been signed.

    Similarly, the Arana and Hadda independent sewage treatment plant (ISTP) projects have yet to reach the financial close originally targeted for the second quarter. The two schemes will provide a combined treatment capacity of 350,000 cm/d.

    Delays extend further down the procurement pipeline. The latest developer bid deadline for the estimated $150m Riyadh East ISTP is 29 September, almost a year after the request for proposals (RFP) was issued in October 2025.

    Procurement for the main contracts for the Jubail-Buraidah and Ras Mohaisen-Baha-Mecca independent water transmission system projects could also slip into 2027, amid delivery-model changes by Water Transmission Company.

    New awards

    The market received a boost in September when Saudi Arabia’s National Water Company (NWC) announced it had signed a SR1.3bn ($347m) deal with a Saudi-Chinese consortium for package 10 of its long-term operations and maintenance programme.

    The consortium – comprising China’s Jiangsu United Water Technology and Saudi-based Armada Holding – will rehabilitate, operate and maintain nine sewage treatment plants (STPs) with a combined design capacity of more than 337,000 cm/d. Based on the latest procurement timeline, it is unclear whether the selected consortium for package 11 will be formally announced this year. Packages 12 and 14 remain under tender while package 16 is next in line, with its RFP not expected to be issued before November.

    NWC is the second-largest awarding entity by value in 2026, accounting for $1.09bn, or about 28% of the total. Saudi Aramco is the largest, with $2.15bn, meaning the two organisations account for more than 82% of awards so far this year.

    Aramco’s activity has been led by two major oil field developments. In June, it awarded the $1.5bn Safaniya onshore surface facilities project: package 1 to a joint venture of Tecnimont and Consolidated Contractors Company. The package includes a water treatment and injection plant supporting upstream production.

    It also awarded the second phase of its Zuluf water treatment project to a joint venture of Almar Water Solutions and AlJomaih Energy & Water. The project will add a 308,000-cm/d treatment facility at Tanajib in the Eastern Province, supplying water for injection at the offshore Zuluf oil field.

    The concentration of awards in industrial projects this year has been notable. Against the slowdown in municipal water infrastructure procurement, much of the value awarded so far has been linked to the water requirements of oil and gas and mining developments.

    The third-largest award is the $350m Taif Ar Rjum water pipeline project, being developed by Saudi Arabian Mining Company (Maaden) in Mecca. The project will support the Ar Rjum gold mining and processing facility and is being developed under a build-own-operate-transfer model. 

    By project type, treatment projects make up the largest share of awards, at $2.85bn or about 72% of the total. Transmission projects account for $980m and cooling projects for a further $110m, while no major desalination or water storage contracts have been awarded so far this year.

    Project pipeline

    The slowdown in awards appears to reflect the timing of projects moving through procurement rather than a fundamental weakening in demand for water infrastructure.

    Saudi Arabia continues to face rising demand for desalination, wastewater treatment and water transmission as population growth and industrial expansion drive demand for water.

    Sharakat, formerly Saudi Water Partnership Company, set out the next phase of the kingdom’s water investment programme in its latest seven-year statement, published in March.

    The plan points to a significant expansion in desalination capacity. Capacity from Sharakat-procured projects is expected to increase from about 3.88 million cm/d in 2025 to roughly 7.18 million cm/d by 2031.

    The increase will be supported by seven new independent water plants (IWPs) with a combined capacity of about 2.8 million cm/d, in addition to projects already operating, under construction or in procurement.

    However, several of the planned projects have yet to move into active procurement, while others have seen their expected timelines pushed back.

    Among the schemes affected are the Ras Al-Khair, Tabuk, Shuqaiq and Jizan IWPs, which have all progressed through prequalification, but have seen changes to their expected procurement schedules.

    The largest is phase two of the Ras Al-Khair IWP, a 600,000-cm/d reverse osmosis desalination plant that has been in development for more than a decade.

    The revised schedule indicates that the $400m Al-Shuqaiq 4 IWP is expected to be the first of the seven new plants to reach commercial operation. Its main contract had been expected to be tendered later this year, but it is now understood that the first RFP will not be issued until early 2027.

  • Kuwait grants loan for GCC grid extension study

    8 September 2026

    The Kuwait Fund for Arab Economic Development has signed a KD200,000 ($647,000) grant agreement with the GCC Interconnection Authority (GCCIA) to finance a feasibility study on extending the Gulf power grid to electricity networks outside the GCC.

    The agreement was signed on 3 September by Ahmed Bin Ali Al-Ibrahim, CEO of the GCCIA, and Kuwait Fund acting director general Rashid Al-Bader.

    The study will assess opportunities to expand the GCC power interconnection system to neighbouring countries. It will examine their electricity requirements and the technical and economic feasibility of connecting their national grids to the Gulf network.

    The Kuwait Fund did not identify the countries or potential interconnection routes. However, it is understood that the study will identify potential phases for future expansion, determine priority projects and assess the most appropriate interconnection options based on technical and economic criteria.

    It will cover the proposed project’s main components, costs, implementation arrangements and expected timeframe. The study will also assess the potential economic and social benefits for GCC member states and connected countries, as well as how the GCC network would operate alongside neighbouring national grids.

    A preliminary assessment of the project’s potential environmental and social impacts will also be carried out, together with proposed mitigation measures.

    The Kuwait Fund has previously provided three loans worth a combined KD78m ($252m) to GCCIA to support expansion of the GCC power interconnection system and its connection to southern Iraq’s electricity grid.

    In August 2025, the fund announced two loans worth KD70m ($224m) for the expansion of the Gulf Power Interconnection Project. The financing included support for the Al-Wafra 400kV substation and infrastructure connecting Kuwait’s grid with Iraq. 

    The Al-Wafra substation facilitates electricity exchanges and enables Kuwait to access surplus power available through the GCC interconnection system.

  • Chinese firm to set up $300m anode facility in the UAE

    8 September 2026

    Beijing-headquartered Sunstone Development has signed a memorandum of understanding (MoU) with the UAE Ministry of Investment to develop an anode production facility in the UAE, with an estimated investment of about $300m.

    The MoU follows Sunstone’s December 2025 joint-venture agreement with Emirates Global Aluminium (EGA) to build the project.

    Upon completion, the plant is expected to replace most of EGA’s current anode imports and support the UAE’s ambition to become one of a limited number of global anode-exporting countries, aligning with the Make It In The Emirates initiative and Operation 300bn.

    The ministry said the agreement reflects its role in helping strategic investors navigate the UAE’s investment ecosystem and convert commitments into long-term operations, in line with the National Investment Strategy 2031.

    By localising a key stage in the aluminium value chain, the facility will reduce reliance on imported anodes, enhance the competitiveness of the UAE aluminium sector and support wider economic diversification.

    The Ministry of Investment and Sunstone will establish a joint working group, chaired by the ministry, to oversee project delivery.

    The project is expected to create skilled employment opportunities for UAE nationals and residents, while strengthening domestic manufacturing capacity and industrial capabilities.
