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.

17 September 2026
An invitation to bid has been issued for a contract to conduct environmental assessments for the project to expand the Mellitah oil and gas complex in Libya.

The bid submission deadline is 2pm today (17 September) Libyan time.

The scope of the project includes provision of:
- An environmental baseline study (EBS)
- An environmental impact assessment (EIA)
- An environmental management plan (EMP)
The client is Mellitah Oil & Gas (MOG), which is a joint venture of Italy’s Eni and Libya’s National Oil Corporation (NOC).

MOG is based in Tripoli and operates both onshore and offshore oil and gas facilities.

The joint venture owns and operates six major oil and gas fields across the North African country.

According to the tender documents, the company that is awarded the contract will need to prepare environmental management measures in compliance with:
- Libyan environmental legislation
- Ministry of Environment requirements
- NOC environmental guidelines
- Applicable international environmental standards and best practices
The expansion of the Mellitah oil and gas complex is part of a project estimated to be worth $8bn.

Security issues and political instability have been a major problem for Libya’s oil and gas sector since the country’s civil war started in 2011.

Earlier this month, the Mellitah oil and gas complex was forced to shut down temporarily due to a protest over deteriorating public services.

The existing onshore complex includes housing, processing units, storage facilities and export facilities.

It also serves as the launch point for the Greenstream pipeline, which delivers Libyan gas directly to Italy.

The planned expansion of the complex will involve:
- Construction of a new fourth gas processing train
- Construction of a third condensate train
- Construction of a third natural gas liquids fractionation train
- Construction of a fourth sulphur recovery unit train
- Installation of a hydrogen sulphide enrichment unit
- Installation of a sulphur recovery unit
- Construction of other associated facilities
The Mellitah complex is located about 100 kilometres west of Tripoli and is a key energy facility in the west of the country.

Dubai announces new 80km highway corridor
16 September 2026

Dubai has approved the construction of the new fourth corridor, a major highway programme aimed at boosting inter-emirate connectivity, increasing road capacity and easing congestion.

The corridor will extend 80 kilometres, from Al-Faya Road in Abu Dhabi to Al-Shanouf Road in Sharjah.

It will include 12 lanes, 72 bridges and 17 tunnels.

The project is expected to reduce travel times by up to 60% and serve more than 3.1 million people, while providing links to Al-Maktoum International airport and Etihad Rail.

It will have the capacity to accommodate 24,000 vehicles per hour in each direction.

The project will be delivered in two phases. The first phase, running from Al-Shanouf Road to Dubai-Al Ain Road, will be delivered at a cost of AED3.5bn ($953m).

The second phase will stretch from Dubai-Al Ain Road to Al-Faya Road in Abu Dhabi.

Hamdan bin Mohammed: In line with the directives of His Highness Sheikh Mohammed bin Rashid Al Maktoum to boost investment in infrastructure, I approved the New Fourth Corridor to strengthen Dubai’s road network and enhance connectivity with the UAE’s federal road network.… pic.twitter.com/zlIyY2yKBN

— Dubai Media Office (@DXBMediaOffice) September 16, 2026

The scheme adds a fourth spine to a network that has long relied on three main corridors: the E11 (Sheikh Zayed Road/Al-Ittihad Road); the E311 (Sheikh Mohamed Bin Zayed Road) and the E611 (Emirates Road), which together carry more than 850,000 vehicles commuting between Dubai and the northern emirates daily.

That concentration has made the route one of the country’s most congested, with peak-hour bottlenecks a persistent problem for residents. The new corridor is designed to divert a significant share of that traffic onto a higher-capacity route, rather than add pressure to the existing network.

The project also aligns with the Dubai 2040 Urban Master Plan, which anticipates population growth to 5.8 million by 2040 and calls for the expansion of roads, railways, airports and ports to support that growth and reinforce Dubai’s position as a global trading hub. This is reflected in the corridor’s direct links to Al-Maktoum International airport and Etihad Rail.

Engineering progresses on Ras Laffan LNG terminal berths

16 September 2026

Register for MEED’s 14-day trial access

Front-end engineering and design (feed) works are progressing on a QatarEnergy LNG project to build 13 liquefied natural gas (LNG) loading berths at the south export terminal in Qatar’s Ras Laffan Industrial City.

Ras Laffan Industrial City, which lies about 90 kilometres north of Doha, is the world's largest integrated LNG production and export complex, comprising 15 processing trains with a total capacity of 77.5 million tonnes a year (t/y). QatarEnergy began LNG operations at the facility, which houses all its processing trains and export infrastructure, in 1984.

According to sources, QatarEnergy LNG, a subsidiary of state enterprise QatarEnergy, awarded the feed contract for the project to build 13 LNG berths at the south export terminal at Ras Laffan to Australia-headquartered Worley.

The contract was awarded to Worley in the second quarter of this year. Its duration is estimated to be 200,000-250,000 man hours, sources told MEED.

Ras Laffan’s LNG processing and export capabilities will increase by up to about 63% when the three phases of QatarEnergy’s estimated $40bn North Field LNG expansion project come into operation by the end of this decade. Engineering, procurement and construction (EPC) works on all three projects are progressing.

QatarEnergy is understood to have committed nearly $30bn to the first two phases – North Field East (NFE) and North Field South (NFS) – which will lift Qatar’s LNG production capacity from 77.5 million t/y to 126 million t/y by 2028.

QatarEnergy awarded the main EPC contracts for NFE in 2021. The project was intended to raise LNG output to 110 million t/y by 2025. The $13bn EPC package – covering the engineering, procurement, construction and installation of four LNG trains, each with a capacity of 8 million t/y – was awarded in February 2021 to a consortium of Japan’s Chiyoda and France’s Technip Energies.

In May 2023, QatarEnergy awarded the $10bn main EPC contract for NFS to a consortium of Technip Energies and Consolidated Contractors Company (CCC). The contract includes two LNG trains, each with a capacity of 7.8 million t/y.

Once fully operational, the first two phases are expected to add 48 million t/y of LNG supply to the global market.

QatarEnergy took the final investment decision on the third phase, North Field West (NFW), this year, awarding an EPC contract estimated at $8bn to a joint venture comprising Technip Energies, CCC and Gulf Asia Contracting in February.

Chiyoda carried out the feed work for the NFW LNG project.

The NFW scope covers the EPC of two LNG trains with a combined capacity of 16 million t/y, as well as associated facilities for gas treatment, natural gas liquids recovery and helium extraction.

In addition to LNG, NFW is expected to produce about 175,000 barrels of oil equivalent a day of condensate, ethane and liquefied petroleum gas.

With all three phases under EPC execution – and NFE scheduled for commissioning later this year – QatarEnergy is positioning itself to remain one of the world’s largest LNG suppliers in the long term.

Design completed for Libyan oil field development

16 September 2026

Register for MEED’s 14-day trial access

Design work has been completed for a project to develop Libya’s I/R oil field, according to industry sources.

The front-end engineering and design work was completed by a team in the London offices of Italy’s EniProgetti and paves the way for the main engineering, procurement and construction contract to be tendered.

One source said: “At the moment, there is no fixed date for when the invitation to bid for the main contract will be issued, but the project has a lot of momentum and is progressing towards tendering.”

The I/R oil field is located in Murzuq Basin in southwestern Libya.

In June this year, Libya's National Oil Corporation (NOC) signed a unified operating agreement for the field.

The I/R field is operated by Akakus Oil Operations, which is a joint venture of NOC in partnership with Spain’s Repsol, France’s TotalEnergies Repsol, Austria’s OMV and Norway’s Equinor.

The agreement in June was signed by NOC as well as its concession partners.

NOC said the agreement would unify operational and administrative procedures related to field management, optimise resource utilisation and support production sustainability.
