UAE ramps up decarbonisation of water sector
10 October 2023
This package on the UAE's water sector also includes:
> Dewa signs Hassyan water project agreements
> Petrojet joins Project Wave contractor team
> Project Wave first phase reaches financial close
> Alpha Dhabi acquires majority stake in Metito
> Hatta reservoir nears completion
> Sharjah moves Hamriyah bid deadline

As a water-scarce country, the UAE has relied on non-conventional water, particularly seawater treated in desalination plants, to meet rising demand.
Over the past decade, the energy-intensive water treatment process, especially when using older technologies, has been a key focus for policymakers tasked with aligning industries with the country’s energy diversification and, more recently, net-zero carbon dioxide emissions agendas.
Decarbonising the water supply has entailed decoupling power and water production and improving the level of treated sewage effluent (TSE) reuse. Other initiatives involve modernising the water pipeline transmission network and tapping renewable energy to power desalination plants.
Demand management initiatives such as tariff reforms and awareness campaigns to make end users conscious of their consumption have also been put in place.
The past few months have marked several milestones in the country’s plan to decarbonise its water sector.
Two private water desalination plants that use reverse osmosis technology to treat seawater are in the final commissioning stage, expanding the UAE’s water production capacity from more energy-efficient plants.
These are the 200 million-imperial-gallon-a-day (MIGD) seawater reverse osmosis (SWRO) plant in Taweela in Abu Dhabi and another plant in Umm al-Quwain, which has a capacity of 150MIGD.
Abu Dhabi’s second major SWRO project, the 120MIGD Mirfa 2 independent water producer (IWP), also reached financial close this year.
Crucially, Abu Dhabi dismantled the thermal-powered Taweelah A2 independent water and power producer (IWPP) plant last year, following the expiry of its long-term offtake contract. The plant’s desalination unit ran on the older multi-stage flash technology.
Hassyan 1
Dubai achieved an important milestone in October when state utility Dubai Electricity & Water Authority (Dewa) and Saudi-headquartered Acwa Power signed a 30-year water-purchase agreement (WPA) and shareholder agreement for the Hassyan 1 IWP project.
Acwa Power will develop and operate the power plant for 30 years at a levelised water cost of 36.5 $cents a cubic metre, a record low, although not nearly as low as the tariff proposed by another developer when the contract was first tendered.
The project supports Dewa’s plan to increase its water desalination capacity from 490MIGD to 750MIGD by the end of the decade.
Dewa has said the Hassyan 1 IWP will be powered by solar energy, further reducing the plant’s carbon footprint.
In Abu Dhabi, the official signing of a WPA for the Shuweihat S4 SWRO project is imminent, which will add another 70MIGD to the emirate’s installed water production capacity once complete.
The Shuweihat 4 plant will cater to potable water demand in Abu Dhabi’s Al-Dhafra region, a key focus of Abu Dhabi’s economic development plan.
The bidding process is also under way for two more SWRO plants in Abu Dhabi. The Hudayriat and Saadiyat RO plants, each with a capacity of 50MIGD, will be developed as one IWP contract.
Emirates Water & Electricity Company (Ewec) has not mandated the inclusion of a solar photovoltaic (PV) plant for its most recent IWP projects, as it did for the Taweelah RO plant in 2019. However, it will likely tap either solar or nuclear energy, or both, for its upcoming SWRO plants in line with its goal to halve its total carbon dioxide emissions to 22 million tonnes a year by 2035.
The northern Sharjah emirate is also procuring its first IWP. The planned Hamriyah SWRO plant will have a capacity of 90MIGD.
In addition to the utility clients, Abu Dhabi National Oil Company (Adnoc) has awarded the contract to develop the first phase of Project Wave, which aims to replace the aquifer water injection systems used to maintain reservoir pressure in Abu Dhabi's onshore oil fields.
The project is expected to reduce the water injection-related energy consumption of the oil fields by up to 30 per cent.
Wastewater
Dubai Municipality activated a major programme this year to develop deep tunnels and sewage treatment plants across the emirate. This long-term project could require an investment of up to AED80bn ($22bn).
Known as the Deep Tunnels Portfolio, the scheme will be developed as a public-private partnership (PPP) initiative and will expand the role of private companies in the emirate’s water infrastructure sector.
It involves the construction of two sets of deep tunnels terminating at two terminal pump stations located at sewerage treatment plants (STPs) in Warsan and Jebel Ali. A conventional sewage and drainage collection system and STPs will be built in Hatta. The scheme also includes recycled water distribution systems connected to the STPs.
Approved by Dubai’s Executive Council in June, 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 Dubai Urban Plan 2040.
In the UAE capital, Abu Dhabi Sustainable Water Solutions, formerly Abu Dhabi Sewerage Services Company, received bids for the contract to design, build and operate a planned TSE polishing plant in Al-Wathba earlier this year.
The plant is expected to have a design capacity of 700,000 cubic metres a day (cm/d), with the potential to expand this to 950,000 cm/d in a subsequent phase. The TSE facility will produce water for higher-end applications compared with TSE produced in a standard sewage treatment plant.
In addition to supporting the UAE’s long-term economic and demographic expansion, these water treatment projects also boost the country’s preferred circular carbon economy approach to energy transition.

Petrofac’s UAE operations continue after layoffs28 November 2025
The UK-headquartered company Petrofac is continuing to work on projects in the UAE after issuing termination notices to around 180 of its staff in the country.
Operations across Petrofac’s portfolio in the UAE are progressing as normal, according to statements sent to several media organisations.
The employees were given notice of their early release from the company on 19 November as part of restructuring measures.
On 27 October, Petrofac announced that it had applied to appoint administrators, a move that potentially put thousands of jobs at risk and increased uncertainty for projects worth billions of dollars in the Middle East and North Africa (Mena) region.
The total value of projects awarded to Petrofac and under construction in the region is $5.83bn, according to information recorded by the regional project-tracking service MEED Projects.
Petrofac also has bids under evaluation for 15 projects in the region worth a total of $19.28bn, according to MEED Projects data.
Ongoing restructuring
On 25 November, Petrofac released a statement saying that it was seeking to appoint administrators to its subsidiary Petrofac International Limited (PIL).
This subsidiary was previously focused on the group’s engineering and construction activities in the Mena region.
In its statement, Petrofac said that its subsidiary would “shortly make an application to the Royal Court of Jersey seeking a letter of request under section 426 of the Insolvency Act 1986”.
It added: “The purpose of this application is to ask the Royal Court of Jersey to issue a letter of request to the High Court of England and Wales and seek its assistance in appointing administrators to PIL.”
Petrofac said that PIL had no ongoing contracts in the Mena region and it intends to redeploy PIL’s 120 staff to other subsidiaries “wherever possible”.
It added: “The administration of PIL is expected to facilitate the purpose of Petrofac Limited’s administration, to help preserve the value of the wider Group and to facilitate the planned M&A solutions.”
Petrofac has said that it is continuing to push ahead with options for alternative restructuring and M&A solutions with key creditors.

Top deals signed at Dubai Airshow 202527 November 2025
The Dubai Airshow 2025 drew to a close on 21 November, with deals exceeding $202bn, double the $101bn secured at the 18th edition in 2023.
This new milestone reinforces Dubai’s position as a global aviation hub and central force shaping the future of the aviation and space industries, according to a statement from the Government of Dubai Media Office.
The 19th edition of the event, held at Dubai World Central under the theme ‘The Future is Here’, also drew record attendance, welcoming 248,788 visitors, including industry leaders, government officials and aviation specialists from across the globe.
More than 1,500 exhibitors took part, with 440 participating for the first time, along with 490 military and civil delegations from 115 countries. The show also included 21 national pavilions, 98 chalets, an extra 8,000 square metres of display space, and a startup ecosystem with 120 startups and 50 investors.
One of the most globally diverse editions to date, this year’s airshow featured the usual mega-orders, but also a surprise fleet pivot and an emerging picture of the region’s biggest players taking control of their futures by influencing the development of tomorrow’s jets and securing their supply chains.
Anchor customer
UAE national carriers placed orders for 502 aircraft during the five-day event, with Emirates leading the charge. On the first day of the airshow, Emirates announced a $38bn order for 65 new Boeing 777-9 aircraft. The airline also ordered 130 GE9X engines from GE Aerospace, which power the new twin-engined planes.
The deal gives Boeing a boost after the 777-9’s debut was delayed to 2027 – but equally significantly, it provides strong backing for Boeing’s feasibility study to develop the 777-10, a larger variant of its 777X family, as Emirates pushes to replace its Airbus A380 fleet.
“Emirates has been open about the fact that we are keen for manufacturers to build larger capacity aircraft, which are more efficient to operate, especially with projected air traffic growth and increasing constraints at airports,” said Sheikh Ahmed Bin Saeed Al-Maktoum, chairman and chief executive of Emirates Airline and Group.
“We fully support Boeing’s feasibility study to develop the 777-10 and have options to convert our latest 777-9 order to the 777-10 or the 777-8.”
Several days later, Emirates also ordered eight more A350-900 aircraft, worth $3.4bn and powered by Rolls-Royce Trent XWB84 engines, while also urging Airbus to explore a larger version of its A350-1000 wide-body.
Emirates’ commitment to new aircraft at the Dubai Airshow 2025 is worth $41.4bn at list prices, and brings the airline’s total wide-body aircraft orders to 375, with deliveries scheduled through 2038.
It was also announced that Emirates would deploy Starlink Wi-Fi across its entire in-service fleet, beginning with Boeing 777 aircraft in November 2025 and completing the rollout by mid-2027.
Airbus pivot
Flydubai also signed a memorandum of understanding (MoU) with Boeing to purchase 75 Boeing 737 MAX aircraft valued at $13bn. In one of the show’s biggest strategic shifts, a further MoU was signed with Airbus for 150 A321neo aircraft, making the airline a new Airbus customer.
Sheikh Ahmed, also chairman and CEO of flydubai, said this addition would diversify the airline’s narrow-body fleet and “enable flydubai to play a key role in the success of Dubai World Central’s expansion plans, an airport we aim to become the largest airport in the world”.
“We look forward to establishing a strong and enduring partnership between flydubai and Airbus,” he said.
Etihad Airways confirmed an order for 32 new Airbus aircraft, including freighters, marking a significant expansion of its wide-body fleet, while Gulf Air, Bahrain’s national carrier, finalised a firm order for 15 787 Dreamliners with options for three more as the carrier looks to further develop its international network. The order adds three Boeing 787s to the airline’s commitment this July and brings Gulf Air’s order book to 17 of the versatile widebody jets.
Saudi Arabia's emerging airline, Riyadh Air, confirmed a purchase of 120 CFM LEAP-1A engines for its incoming A321neo fleet.
Taking control
In a clear sign that Gulf airlines are taking charge of their supply chains, Emirates and France's Safran Seats signed an MoU to bring a manufacturing and plane seat assembly factory to Dubai. The joint industrial cooperation, the first of its kind, will initially focus on Emirates’ business and economy class seats for cabin retrofit projects, with plans to expand into new aircraft in the future.
“This agreement with Safran marks a pivotal and strategic cooperation that establishes Dubai as an aerospace manufacturing hub,” commented Sheikh Ahmed. “We're bringing world-class seat production capabilities and supply chain to our doorstep, creating highly skilled jobs, and developing capabilities to support Emirates and produce seats for export to other carriers.”
Emirates is also securing its own engine maintenance capabilities, signing an MoU with Rolls Royce to conduct engine maintenance, repair and overhaul on its own A380 fleet at a new plant in Dubai from 2027.
Green airline fuel
Sustainability was a core priority at the airshow, with initiatives including the supply of sustainable aviation fuel (SAF) for participating aircraft, the use of electric and propane-powered ground support equipment in partnership with Jetex, and exhibition halls run entirely on renewable energy.
On the sidelines of the event, Emirates and Enoc Group signed a memorandum of understanding to explore and develop joint initiatives for the supply of SAF to Emirates at its Dubai hub.
Defence deals
Capping the exhibition were the 36 deals signed on behalf of the Ministry of Defence and Abu Dhabi Police by the UAE’s Tawazun council – the national authority mandated to enable, regulate and sustain the UAE’s defence and security industrial ecosystem. Valued at AED25.455bn, the deals included contracts for drones, rescue gear, aircraft parts and support.

Riyadh to award Terminal 6 contract by mid-202627 November 2025

Saudi Arabia’s King Salman International Airport Development Company (KSIADC) is targeting mid-2026 to award the contract for the construction of Terminal 6 at King Salman International airport (KSIA) in Riyadh.
KSIADC, which is backed by Saudi sovereign wealth vehicle, the Public Investment Fund, plans to deliver the package on an early contractor involvement (ECI) basis.
MEED understands that the ECI timeframe will be around six months.
The ECI process requires selected contractors to submit methodologies for the project and a design proposal.
In July, MEED exclusively reported that several contractor consortiums had recently submitted proposals for a contract to develop the first phase of Terminal 6 and the Iconic Terminal at KSIA.
MEED understands that the consortium formations are:
- Albawani / Kalyon / Cengiz (local/Turkiye/Turkiye)
- China State Construction Engineering Corporation / El-Seif Engineering Contracting / Midmac (China/local/Qatar)
- FCC Construction / Almabani / Ic Ictas / Al-Rashid Trading & Contracting (Spain/local/Turkiye/local)
- Modern Building Leaders / Powerchina / Metallurgical Construction Corporation (local/China/China)
- UCC Holding / Consolidated Contractors Company (Qatar/Greece)
- Orascom / Shibh Al-Jazira Contracting Company / Larsen & Toubro (Egypt/local/India)
- Samsung / Nesma & Partners / Limak / Alayuni Investment & Contracting (South Korea/local/Turkiye/local)
- WeBuild / TAV / Algihaz (Italy/Turkiye/local)
In May, MEED reported that US firm Bechtel Corporation had been appointed as the delivery partner for the terminals at KSIA.
According to local media reports, KSIADC’s acting CEO, Marco Mejia, said the project developer has completed the project’s masterplan.
The reports added that Terminal 6 will boost the airport’s capacity by 40 million passengers.
The project is expected to be delivered before the start of the Expo 2030 Riyadh event.
In August last year, KSIADC confirmed that it had signed up several architectural and design firms for the various elements of the project.
KSIADC said that UK-based Foster+Partners will design the airport’s masterplan, including the terminals, six runways and a multi-asset real estate area.
US-based engineering firm Jacobs will provide specialist consultancy services for the masterplan and the design of the new runways.
The client also confirmed the appointment of UK-based engineering firm Mace for the delivery partner role on the project.
The airspace design consultancy contract was awarded to local firm Nera.
Project scale
The project covers an area of about 57 square kilometres (sq km), allowing for six parallel runways, and will include the existing terminals at King Khalid International airport. It will also include 12 sq km of airport support facilities, residential and recreational facilities, retail outlets and other logistics real estate.
If the project is completed on time in 2030, it will become the world’s largest operating airport in terms of passenger capacity, according to UK analytics firm GlobalData.
The airport aims to accommodate up to 120 million passengers by 2030 and 185 million by 2050. The goal for cargo is to process 3.5 million tonnes a year by 2050.
Saudi Arabia plans to invest $100bn in its aviation sector. Riyadh’s Saudi Aviation Strategy, announced by the General Authority of Civil Aviation, aims to triple Saudi Arabia’s annual passenger traffic to 330 million travellers by 2030.
It also aims to increase air cargo traffic to 4.5 million tonnes and raise the country’s total air connections to more than 250 destinations.
