EPC teams start forming for $22bn Dubai tunnels

24 September 2024

Register for MEED's 14-day trial access 

Some prequalified engineering, procurement and construction (EPC) companies for the contracts to develop and operate various packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project have started forming teams in anticipation of the next stage of the tendering process.    

In August, Dubai Municipality prequalified 21 companies and consortiums that can bid for three packages known as J1, J2 and W, and 19 for a fourth package known as J3, of the six-package project.

Some companies are in the process of finalising their partners, while at least one has said it does not intend to tap a partner.

While the country of origin is expected to play a role in the formation of teams, it is expected that the complementarity of the companies' expertise and resources will be crucial in the selection process.  

The client and its advisers have opted to prequalify EPC contractors ahead of investors in a departure from the classic public-private partnership (PPP) procurement process.

"The idea is to issue the technical information pack to the prequalified EPC contractors before the prequalification process for investors starts, allowing EPC contractors time to undertake the design process," a source familiar with the project recently told MEED.

He added: "These designs should be ready once Dubai Municipality completes the prequalification process for investors, saving roughly three months compared to the usual route, where the prequalification processes for developers and EPC contractors are done simultaneously."

The staggered prequalification process is expected to help ensure the request for proposals process takes about six months rather than the typical nine months.

Six packages

Under the current plan, the $22bn DSST project is broken down into six packages, which will be tendered as PPP packages with concession periods lasting between 25 and 35 years.

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

The second package, J2, covers the southern section of the Jebel Ali tunnels, which will extend 16km and have 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.

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

J3 will be procured under a design-build-finance model with a concession period of 25-35 years. Once completed, Dubai Municipality will operate them, unlike the first three packages, which are planned to be operated and maintained by the winning PPP contractors.

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

The project’s remaining two packages entail the expansion and upgrade of the Jebel Ali and Warsan sewage treatment plants (STPs), and will be procured in a process separate from the four DSST-DLT components.

Market-sounding

Dubai Municipality is expected to hold a market-sounding event for investors, MEED reported in early September .

The event is set to take place during the first week of October, a few weeks before interested investors submit their statements of qualifications (SOQ) for the projects' various packages.

MEED previously reported that the client had extended the SOQ submission deadline from 5 September to 21 October.

 Gravity system project

The DSST 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 currently has two major sewerage catchments. The first in Deira is Warsan, where the Warsan STP treats the flow.

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

According to a source close to the project, the DSST will replace 120 pump stations, saving approximately 100 gigawatt-hours of electricity annually.

  • Bahrain advances utility reform

    7 November 2025

     

    In September, Bahrain’s government referred a draft law to parliament to restructure the kingdom’s electricity and water sector.

    This proposes dissolving the Electricity & Water Authority (Ewa) and transferring its assets and functions to a newly established National Electricity & Water Company, which will operate under the oversight of the Electricity & Water Regulatory Authority. 

    The reform marks the first full structural overhaul of Bahrain’s utilities sector in nearly two decades and signals a shift towards a more commercially driven model. 

    Regulatory and operational roles would be separated for the first time, allowing private sector participation under transparent licensing and tariff systems, aligning Bahrain with utility reforms seen in Saudi Arabia, Oman and the UAE.

    It comes amid a relatively subdued year for new contracts that broadly falls in line with 2024’s performance. Most significantly, Bahrain continues to move towards its two upcoming utility public-private partnership (PPP) schemes, the Sitra independent water and power project (IWPP) and the Al-Hidd independent water project (IWP).

    In August, a developer tender was issued for the main works package for the Sitra IWPP. This followed the prequalification of seven companies and consortiums, reflecting a wide range of international interest.

    The planned Sitra IWPP replaces the previously planned Al-Dur 3 and will be the first IWPP project to be awarded since the 1,500MW Al-Dur 2 IWPP was completed in 2021.

    The combined-cycle gas turbine (CCGT) plant is expected to have a production capacity of about 1,200MW of electricity, while the project’s seawater reverse osmosis (SWRO) desalination unit will have a production capacity of 30 million imperial gallons a day (MIGD) of potable water. The main contract is expected to be awarded by the end of the year, with commercial operations set for 2029. 

    A developer tender was also recently launched for Bahrain’s first independent, standalone SWRO plant following a prequalification process that shortlisted nine companies and consortiums.

    The Al-Hidd IWP is expected to have a production capacity of about 60MIGD of potable water and be completed in 2028. It is likely to be the last IWPP for Bahrain, which aims to reach net-zero carbon emissions by 2060.

    The imminent launch of the two projects boosts Bahrain’s projects pipeline, which has experienced muted growth in the aftermath of the Covid-19 pandemic, carried by relatively small-scale projects.

    Solar PV projects

    The creation of the National Electricity & Water Company as Bahrain’s new operational entity could also support the rollout of future renewable energy schemes. 

    As a corporatised offtaker, the company will be able to enter long-term power purchase agreements (PPAs) with private developers under a more bankable framework. Currently, these are negotiated by Ewa on a case-by-case basis.

    The government recently signed a 123MWp solar PPA with the UAE’s Yellow Door Energy, highlighting growing private sector interest in the market. The project includes the world’s largest single-site rooftop solar installation and will be developed at Foulath Holding’s industrial complex in Salman Industrial City.

    Bahrain has already set a target to source 20% of its energy from renewables by 2035 and reach net-zero emissions by 2060.

    In October, Ewa also issued a tender for the development of the Bilaj Al-Jazayer solar independent power project (IPP). The planned 100MW project will be developed on a build-own-operate basis with a 25-year contract term.

    In parallel, Bahrain is broadening its long-term energy strategy beyond solar. In July, the kingdom signed a cooperation agreement with the US on the peaceful use of nuclear energy, aimed at advancing research and potential deployment of small modular reactor (SMR) technology.

    For countries like Bahrain, which has limited land availability and high energy demand growth, SMRs could offer a way to produce low-carbon, reliable baseload power without requiring vast areas of land for solar or wind farms. 

    Officials have indicated that SMRs, along with floating solar solutions, are being studied as part of a broader push to diversify energy sources and expand renewable generation capacity.

    Water and waste

    Bids for four Ewa-owned projects are currently being evaluated. This includes the construction of a new SWRO desalination plant on Hawar Island and rehabilitation works for the Ras Abu Jarjur water treatment plant in Askar. Contracts for both projects are expected to be awarded this year.

    Bahrain’s Ministry of Works (MoW) is the other client for the island-state’s power and water infrastructure-related projects. It has awarded three smaller sewage-related contracts this year.

    It is also preparing to tender the construction of a $130m sewage treatment plant in Khalifa City, which will be developed in two phases. Meanwhile, the construction of MoW’s sewerage scheme phase 2 network in Bahrain remains in the early design stage with no further updates.

    As Bahrain moves ahead with these projects, the new electricity and water law could define how future investments are structured, regulated and financed. This could reshape the kingdom’s utilities landscape for decades to come.

  • Masdar and OMV sign 140MW green hydrogen plant deal

    7 November 2025

    Register for MEED’s 14-day trial access 

    Abu Dhabi Future Energy Company (Masdar) has signed a binding agreement with Austrian energy company OMV to develop and operate a major green hydrogen production plant in Austria.

    The 140MW green hydrogen electrolyser plant will be Europe's fifth-largest hydrogen plant, according to Masdar chairman, Sultan Ahmed Al-Jaber.

    It will be built in Bruck an der Leitha, about 40 kilometres southeast of Vienna.

    The facility will be developed under a newly established joint venture, in which Masdar owns 49% and OMV holds the majority 51% stake.

    The agreement was signed at the Abu Dhabi International Petroleum Exhibition and Conference (Adipec), in the presence of Al-Jaber; Austria’s Federal Minister of Economy, Energy and Tourism, Wolfgang Hattmannsdorfer; OMV CEO Alfred Stern; and Masdar CEO Mohamed Jameel Al-Ramahi.

    It is expected that the project will reach financial close in early 2026, subject to final documentation, shareholder consent and regulatory approvals.

    Construction began in September, with operations scheduled to start in 2027.

    OMV, which already operates a 10MW electrolyser in Schwechat, will procure renewable electricity for hydrogen production and retain ownership of the output.

    Several large-scale hydrogen facilities across Europe are currently under construction.

    In 2024, Germany's Siemens Energy signed a deal with German utility EWE to build a 280MW green hydrogen electrolysis plant. This is expected to begin operations in 2027.

    Masdar and OMV previously signed a letter of intent to cooperate on green hydrogen, synthetic sustainable aviation fuels (e-SAF) and synthetic chemicals in both the UAE and central and northern Europe.

  • Firms submit Saudi customs warehouses PPP bids

    7 November 2025

     

    Three Saudi-based firms submitted bids on 29 September for a contract to build new customs warehouses in Saudi Arabia.

    The project is being tendered as a public-private partnership (PPP) on a design, build, finance, operate, maintain and transfer basis, with a contract duration of 15 years, including the construction period.

    The bidders include:

    • Al-Drees Petroleum & Transport Services Company
    • Lamar Holding
    • Mada International Holding

    The contract scope covers the development of 13 warehouses – including the design and construction of 12 new facilities and the renovation of one – across 13 different points of entry in the kingdom, along with the maintenance of all sites.

    The contract also includes the supply of equipment, as well as logistical support and cleaning services, for all new and existing warehouses at 38 points of entry across the kingdom.

    In January, the Zakat, Tax and Customs Authority (Zatca), through the National Centre for Privatisation and PPP (NCP), prequalified five companies to bid, MEED reported.

    The client issued the expressions of interest (EOI) and request for qualifications (RFQ) notices for the project in October last year.

    PPP plans

    In April 2023, Saudi Arabia announced a privatisation and public-private partnership (P&PPP) pipeline comprising 200 projects across 16 sectors.

    The P&PPP pipeline aims to attract both local and international investors and ensure their readiness to participate in the schemes tendered to the market.

    The initiative supports the kingdom’s efforts to enhance the attractiveness of its economy and increase the private sector’s contribution to GDP.

  • KBR selected for Iraq gas project

    7 November 2025

    Register for MEED’s 14-day trial access 

    US-based KBR has been selected by Turkiye’s Enka to provide detailed design services for its part of the broader $27bn Gas Growth Integrated Project (GGIP) masterplan.

    KBR was selected to provide the detailed design services after successfully completing the front-end engineering and design (feed) work for Enka’s central processing facility (CPF) package, according to a statement issued by the company.

    The wider GGIP project is being developed by France’s TotalEnergies along with its partners Basra Oil Company (BOC) and Qatar Energy.

    In September, Enka signed a contract to develop a CPF at Iraq’s Ratawi oil field as part of the second phase of the field’s development.

    Enka did not give a value for the contract, but it is believed to be worth more than $1bn.

    The contract covers engineering, procurement, supply, construction and commissioning (EPSCC) of the CPF for the project known as ‘Associated Gas Upstream Project Phase 2 (AGUP2)’.

    The aim of the AGUP2 project, due to start in 2028, is to process oil and associated gas from the Ratawi oil field to increase production capacity to 210,000 barrels a day of oil and 154 million standard cubic feet a day of gas.

    GGIP masterplan

    The GGIP programme is being led by TotalEnergies, which is the operator and holds a 45% stake.

    Basra Oil Company and QatarEnergy hold 30% and 25% stakes, respectively. The consortium formalised the investment agreement with the Iraqi government in September 2021.

    The four projects that comprise the GGIP are:

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

    The CSSP is designed to support oil production in Iraq’s southern oil and gas fields – mainly Zubair, Rumaila, Majnoon, West Qurna and Ratawi – by delivering treated seawater for injection, a method used to boost crude recovery rates and improve long-term reservoir performance.

    China Petroleum Engineering & Construction Corporation (CPECC) won a $1.61bn contract in May to execute EPC works to build the gas processing complex at the Ratawi field development.

    CPECC’s project team based in its office in Dubai is performing detailed engineering works on the project.

    In August last year, TotalEnergies awarded China Energy Engineering International Group the EPC contract for the 1GW solar project at the Ratawi field. A month later, QatarEnergy signed an agreement with TotalEnergies to acquire a 50% interest in the project.

    The 1GW Ratawi solar scheme will be developed in phases that will come online between 2025 and 2027. It will have the capacity to provide electricity to about 350,000 homes in Iraq’s Basra region.

    The project, consisting of 2 million bifacial solar panels mounted on single-axis trackers, will include the design, procurement, construction and commissioning of the photovoltaic power station site and 132kV booster station.

    Separately, in June, TotalEnergies awarded CPPE an EPC contract worth $294m to build a pipeline as part of a package known as the Ratawi Gas Midstream Pipeline.

    Also, TotalEnergies awarded UK-based consultant Wood Group a pair of engineering framework agreements in April, worth a combined $11m, under the GGIP scheme.

    The agreements have a three-year term under which Wood will support TotalEnergies in advancing the AGUP.

    One of the aims of the AGUP is to debottleneck and upgrade existing facilities to increase production capacity to 120,000 b/d of oil on completion of the first phase, according to a statement by Wood.
