UAE begins massive reverse osmosis buildup

11 April 2023

This package on the UAE's water sector also includes:

Dewa extends Hassyan IWP bid deadline

Adnoc resumes Project Wave negotiations

Sharjah issues first independent water tender

Ewec rules out solar in desalination projects

French/local team wins contract to build Mirfa 2 IWP

Adnoc selects Cobra-led team for PPP project


State utilities in the UAE are seeking to increase the share of seawater reverse osmosis (SWRO) technology in the overall capacity of their desalination plants in line with their carbon emission reduction targets and the UAE’s net-zero by 2050 goal.

This will end the domination of water production capacity by thermal desalination plants over the past decades.

The demand for additional SWRO capacity is especially evident in Abu Dhabi, where nearly half of the existing water desalination capacity will come out of contract between 2025 and 2029.

The power- and water-purchase agreements (P/WPA) for four major utility plants in Abu Dhabi, with a total combined water desalination capacity of 441 million imperial gallons a day (MIGD), will expire during this period.

Unlike the thermal power plant components of these independent water and power projects (IWPPs), which are subject to extension negotiations, the state utility Emirates Water & Electricity Company (Ewec) is inclined to dismantle all thermal desalination plants associated with these assets – or convert them into SWRO plants – upon the expiry of their contracts. This strategy aligns with its goal to halve its carbon emissions.

Over the next two to four years, Ewec envisages putting 290MIGD of SWRO capacity in place. This is in addition to the Taweelah SWRO plant’s remaining 100MIGD of capacity that is yet to enter commercial operation. Once this plant is at full capacity, it will plug in the capacity from Taweelah A2, the emirate’s first thermal IWPP, which was mothballed in 2021.

Recent SWRO projects in Abu Dhabi include the 120MIGD Mirfa 2 independent water producer (IWP) project, which France’s Engie is developing; the 70MIGD Shuweihat 4 IWPHudayriat and Saadiyat islands, which will each have a capacity of 50MIGD.

Both Mirfa 2 and Shuweihat 4 have a target commercial operation date of 2025, while the two Abu Dhabi Islands IWP projects are expected to provide replacement capacity for the Sas al-Nakhl plant, whose contract expires in 2027.

Longer term, Ewec will need to procure 494MIGD of SWRO capacity by 2036, under the base-case scenario of its 2023-29 Statement of Future Capacity Requirements.

Demand fluctuations

Demand for desalinated water in Abu Dhabi over the short term is anticipated to decrease from just under 800MIGD in 2022 to 764MIGD this year. This is due to reduced exports to Etihad Water & Electricity (Ewe), which is commissioning its first 150MIGD IWP in Umm al-Quwain.

Demand is expected to grow slowly between 2023 and 2029, when it is projected to reach 805MIGD. This is just slightly higher than in 2022, primarily due to recycled water replacing desalinated water as the dominant irrigation supply source.

In Dubai, the procurement process is under way for the 120MIGD Hassyan IWP. The contract for the emirate’s first IWP was tendered before and awarded in 2020, but the project stalled and Dewa relaunched the tender in 2022.

Four teams led by Engie, Saudi Arabia’s Acwa Power, Spain/South Korea’s GS Inima and Metito are understood to be among those qualified to bid for the contract.

The project has a planned capacity of 120MIGD, with an alternative proposal for an aggregate capacity of 180MIGD. Dewa expects to commission it in phases between 2025 and 2026.

The facility is part of Dewa’s plan to increase its water desalination production capacity from 490MIGD to 750MIGD by 2030. By this time, it envisages RO to account for 41 per cent of its overall desalination capacity, in support of Dubai’s 2050 Clean Energy Strategy.

Northern emirates

As previously stated, the Northern Emirates’ first 150MIGD IWP in Umm al-Quwain is undergoing commissioning. This frees up capacity for Abu Dhabi, which has been exporting both water and electricity to the smaller northern UAE emirates.

In early April, Sharjah Electricity & Water Authority also issued the request for proposals for the contract to develop Sharjah’s first IWP. Located next to an existing desalination plant in Hamriyah, the planned IWP will have a capacity of 90MIGD.

UAE power sector shapes up ahead of Cop28

Other projects

Abu Dhabi Sewerage Services Company is evaluating proposals received earlier this year for a contract to design and build a treated sewage effluent (TSE) polishing plant in Al-Wathba

The plant is expected to have a design capacity of 700,000 cubic metres a day (cm/d), with the potential to expand this capacity to 950,000 cm/d in a subsequent phase. The TSE facility will produce water for higher-end applications than the TSE produced at standard sewage treatment plants.

The largest individual projects within the sector are the two seawater treatment plants, frequently called Project Wave, being procured by Abu Dhabi National Oil Company (Adnoc).

The Mirfa and Al-Nouf nanofiltration plants and their associated utilities have budgets of between $2bn and $2.5bn each. The Mirfa package is in the advanced procurement stage, with negotiations continuing between Adnoc and the shortlisted bidders as this article is published.

  • Riyadh sets December deadline for Prince Mishaal Road

    20 November 2025

     

    The Royal Commission for Riyadh City (RCRC) has allowed contractors until 3 December to submit bids for a contract to develop Prince Mishaal Bin Abdulaziz Road Axis-Taif Road in Riyadh.

    The previous deadline was 19 November.

    The scope of work covers general road improvement works, including street upgrades, drainage works, relocation of existing utilities, dry and wet utilities, and other associated infrastructure. RCRC is investing in improving the road network in and around the kingdom's capital.

    Earlier in November, MEED reported that RCRC had begun post-tender clarifications with bidders for a contract covering upgrade works on Najm Al-Din Al-Ayoubi Road in Riyadh.

    The scope of work covers general road improvement works, including upgrades to three bridges at Al-Zahabi Road, Abdulrahman Adakhel Road and Atia Al-Saady Road.

    In February, RCRC announced plans to develop eight road projects in Riyadh at an estimated cost of more than SR8bn ($2bn).

    The projects form part of the second group in the Riyadh Ring Roads and Main Axes development programme.

    The schemes include:

    • The northern part of the Prince Turki Bin Abdulaziz Al-Awwal Road development project, with a length of more than 6 kilometres (km). The scope includes the development of two main intersections, the construction of three bridges and a tunnel.
    • The middle section of the Al-Thumama Road Axis development project. The scheme will cover about 10km and includes the development of five main intersections and the construction of 11 bridges and five tunnels.
    • The Imam Abdullah Bin Saud Road development project, which will stretch about 9km and includes the development of four main intersections, the construction of three bridges and two tunnels.
    • The Dirab Road development project, which will cover 9km and includes the development of two main intersections and the construction of nine bridges.
    • The Imam Muslim Road development project, which stretches 12km and includes the development of four main intersections and the construction of four bridges. The project will serve as the future extension of the Prince Turki Bin Abdulaziz Al-Awwal Road Axis to the south.
    • The road network development project surrounding King Abdullah Financial Centre, with a length of 20km. This includes the development of three main intersections and the construction of 19 bridges.
    • The construction of a bridge at the intersection of King Salman Road in the east with Abu Bakr Al-Siddiq Road in the north.
    • The first package of engineering modifications for crowded sites in Riyadh, encompassing improvements to alleviate traffic congestion during peak times.

    In August last year, RCRC confirmed it had awarded four contracts worth SR13bn ($3.46bn) as part of the first phase of the programme to develop the city’s road network.

    RCRC said the first phase will develop the axis of the main and ring roads to improve traffic movement in the city.

    Other major projects by RCRC include Riyadh Metro, Riyadh Art, Sports Boulevard, King Salman International Park and the Green Riyadh project.

  • Riyadh advances with rail link prequalifications

    20 November 2025

     

    Saudi Arabia Railways (SAR) is expected to begin the second stage of the prequalification process for a contract covering the construction of a new railway line, known as the Riyadh Rail Link, which will run from the north to the south of Riyadh.

    MEED understands that the consortiums need to propose self-funded financing arrangements for the project as part of the new round of prequalifications.

    Contractors submitted their initial prequalification documents earlier this month.

    The scope of work includes constructing a 35-kilometre-long double-track railway line connecting SAR’s North-South Railway to the Eastern Railway network.

    The contract also covers the procurement, construction and installation of associated infrastructure such as viaducts, civil works, utility installations, signalling systems and other related works.

    The project is expected to form a key component of the Saudi Landbridge railway.

    The Saudi Landbridge is an estimated $7bn project comprising more than 1,500km of new track. Its core component is a 900km new railway between Riyadh and Jeddah, which will provide direct freight access to the capital from King Abdullah Port on the Red Sea.

    Other key sections include upgrades to the existing Riyadh-Dammam line and a link between King Abdullah Port and Yanbu.

    The start of tendering activity for the Riyadh Rail Link project makes the construction of the Saudi Landbridge more likely. 

    The project is one of the kingdom’s most anticipated infrastructure programmes. Plans to develop it were first announced in 2004, but the project was put on hold in 2010 before being revived a year later.

    Key stumbling blocks were rights-of-way issues, route alignment and its high cost.

    In December 2023, MEED reported that a team of US-based Hill International, Italy’s Italferr and Spain’s Sener had been awarded the contract to provide project management services for the programme.

    If it proceeds, the Landbridge will be one of the largest railway projects ever undertaken in the Middle East – and among the biggest globally.

  • Wood Group wins Iraq oil contract

    20 November 2025

    Register for MEED’s 14-day trial access 

    Aberdeen-based Wood Group has won a contract to deliver project management and engineering services for PetroChina at the West Qurna-1 oil field in southern Iraq, according to a statement from the company.

    Under the terms of the contract, Wood will manage engineering, procurement and construction (EPC) projects at the field. 

    Located approximately 50 kilometres northwest of Basra, West Qurna-1 holds more than 20 billion barrels of recoverable reserves.

    Ellis Renforth, Wood’s president of operations for the Europe, Africa and Middle East region, said: “This contract award deepens our decade-long partnership at West Qurna-1 and reflects the continued trust placed in Wood to deliver complex energy solutions in Iraq. 

    “We’re proud to combine our global expertise with a strong local workforce to help support Iraq’s energy ambitions.”

    The contract will be delivered by nearly 200 Wood employees based in Iraq and the UAE, the company said.

    On 17 November, in a vote, 88% of Wood Group’s shareholders backed the company’s takeover by Dubai-based Sidara.

    The vote came after months of delay, while Wood struggled to agree its accounts with its auditor.

    The company’s accounts were eventually published on 30 October, showing a pre-tax loss of more than £2bn and evidence that the auditor was still not satisfied with the figures going back several years.

    Wood Group accepted a $292m conditional takeover bid from Sidara in August.

    As of February, Wood Group employed 35,000 people across about 60 countries, many in consulting and engineering roles.

    In the Middle East, the company has project contracts in Iraq, Kuwait, Oman, Qatar, Saudi Arabia and the UAE, where it has opened its third office in Sharjah.
