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.

  • Egypt signs PPA for 1GW Ras Shokeir wind farm

    2 September 2026

    Register for MEED’s 14-day trial access 

    A joint venture of the local Hassan Allam Utilities Energy and Infinity Power has signed a power purchase agreement (PPA) with Egyptian Electricity Transmission Company (EETC) for the development of the 1GW Ras Shokeir wind project in Egypt.

    The project is located in Egypt’s Red Sea Governorate, within the Gulf of Suez wind corridor. It will cover approximately 143 square kilometres.

    The PPA has a 25-year term. The project will supply electricity to Egypt’s national grid.

    Ras Shokeir is expected to generate enough electricity to power more than 1.2 million Egyptian homes. It is also expected to avoid more than 1.36 million tonnes of CO2 emissions annually.

    The PPA was signed by EETC chairperson Mona Rizk and Infinity Power co-founder and CEO Nayer Fouad, representing the Infinity Power-Hassan Allam consortium.

    The signing brings the project closer to development as Egypt seeks to expand its renewable energy capacity. Egypt has set a target for renewable energy to make up 42% of the electricity mix by 2030 and 65% by 2040.

    This includes the 500MW Amunet 2 wind project, which is being developed by UAE-headquartered Amea Power following the commissioning of the first Amunet wind project in June 2025.

    Hassan Allam Utilities Energy and Infinity Power are also developing Egypt’s $560m West Minya solar plant, which will combine 1,000MWac of solar photovoltaic capacity with a 600MWh battery energy storage system.

    In June, MEED reported that a joint venture of Hassan Allam Construction and India’s Sterling & Wilson Renewable Energy had won the engineering, procurement and construction contract for the project.

  • Bahrain receives bids for Hawar desalination plant

    1 September 2026

    Bahrain’s Electricity & Water Authority (EWA) has received three bids for an engineering, procurement and construction (EPC) contract to develop a new brackish-water reverse osmosis desalination plant on Hawar Island.

    The tender was opened on 31 August. The plant is designed to produce 300 cubic metres of potable water a day.

    The bidders and their prices are:

    • International Agencies Company (Bahrain): BD371,800 ($989,000)
    • Bokhowa Contracting & Trading Group (Bahrain): BD411,400 ($1.09m)
    • Almoayyed Contracting (Bahrain): BD646,393 ($1.72m)

    All three bids were accepted at opening. Bokhowa’s bid was accepted with a condition.

    EWA’s Planning and Studies department issued the tender under a selected local GCC invitation.

    As MEED understands, the project is separate from a larger seawater reverse osmosis (SWRO) desalination plant also planned for Hawar Island.

    In January, MEED reported that Malaysia-based Sparco Engineering submitted the lowest bid of BD3.23m ($8.6m) for an EPC contract to build a new SWRO desalination plant on Hawar Island.

    The contract covers the construction of the new Hawar SWRO desalination plant, designed to produce 1 million imperial gallons a day of potable water.

    EWA received 10 bids for the project. The bids submitted by Sparco Engineering and Redaa Developing were “accepted with conditions”, the authority said at the time.

    The Hawar Islands form an archipelago of 16 desert islands and islets located approximately 26 kilometres southeast of Ras Al-Bar in Bahrain. The largest island, Hawar, is about 17km long and hosts an eco-resort.

    The Hawar desalination plant project will connect with two related contracts: one covering the construction of the offshore seawater intake and outfall systems, and another involving the construction of two ground storage tanks and the installation of water transmission pumps.

    Hawar water packages 

    MEED previously reported that UAE-based Noble Development had submitted the lowest bid for a contract to construct a seawater intake and outfall system to serve a new desalination plant on the island.

    However, no contract has been awarded yet, and it is understood that it may be retendered.

    A third package linked with the SWRO project was tendered last November, with Greece-headquartered Ergotem submitting the lowest bid of $1.92m.

    This contract covers the construction of two steel ground storage tanks with a capacity of 1 million gallons each, pumping stations, motors, pipelines and associated facilities.

    The main desalination plant contractor will be required to ensure that the plant’s design and construction align technically and operationally with these two projects so that all three components function together as one integrated system.

    As MEED understands, this contract is also yet to reach the award stage.

  • Gas processing takes centre stage in Mena region

    1 September 2026

     

    National oil companies (NOCs) in the Middle East and North Africa (Mena) region are accelerating investment in gas processing and associated downstream infrastructure as demand rises and governments prioritise lower-carbon energy growth.

    Rising regional gas consumption is being driven by rapid population growth, greater household electrification, expanding industrial bases and demand from gas-intensive downstream segments such as petrochemicals, fertilisers and metals. 

    Power generation and water desalination are also key sources of demand, while new industrial zones are adding further baseload requirements.

    The push is not only about producing more gas, but also about treating it. As fields mature, a larger share of supply is sour, tight or associated gas that requires more complex processing, sulphur recovery and liquids handling.

    At the same time, NOCs are targeting higher-value outputs such as ethane, liquefied petroleum gas and condensates, to feed chemicals and export markets. 

    This makes fractionation and the recovery of natural gas liquids (NGL) central to project economics. Emissions constraints further elevate the importance of efficient plants, flare reduction schemes and integrated gas-gathering networks.

    Investment accelerates

    The multibillion-dollar projects planned and under way in the region illustrate the scale of investment flowing into gas processing infrastructure. 

    Saudi Aramco is advancing gas and liquids infrastructure linked to its $100bn Jafurah unconventional gas development, in addition to expansions to strengthen the kingdom’s Master Gas System transmission network.

    In the UAE, Abu Dhabi National Oil Company (Adnoc) continues to expand sour gas processing and downstream-
    linked gas treatment capacity to support domestic power needs and industrial growth. Meanwhile, debottlenecking and compression and pipeline projects improve system resilience. 

    QatarEnergy, already a global leader in liquefied natural gas (LNG), is expanding upstream gas handling, condensate and NGL infrastructure as part of its North Field expansion programme. The programme will also increase feedstock supplies for local industry. 

    In Oman, majority state-owned Petroleum Development Oman (PDO) and its partners are similarly focused on gas processing, compression and network upgrades to sustain supplies to power generation, industrial users and LNG.


    Saudi Aramco is expanding gas-processing and NGL infrastructure as domestic demand grows


    Leading spender

    The Mena region has seen significant spending on gas processing projects so far in 2026, with year-to-date capital expenditure (capex) exceeding levels recorded in any year since at least 2015.

    Adnoc Gas, the natural gas processing business of Adnoc Group, has been the biggest spender this year, following final investment decisions (FIDs) on the second and third phases of its Rich Gas Development (RGD) programme, worth a total of $8.2bn. The FIDs are part of the company’s previously committed $28bn capex budget for 2026-30.

    The second phase of the RGD programme relates to the construction of a new gas processing train at the Habshan gas processing complex, while the third phase covers an NGL fractionation train at the Ruwais gas processing facility.

    In its Q2 2026 financial results, Adnoc Gas said China-based Wison Engineering had secured the $3.9bn EPC contract for phase two of the RGD, while Italian contractor Tecnimont was selected for the $4.3bn phase three contract.

    Wison Engineering said the EPC contract for RGD phase two is the largest in its history. The Hong Kong-listed company said the $3.9bn EPC contract, together with an associated 220kV switch station, brings the total contract value to approximately $4.04bn. The scope includes gas pipelines, separation and condensate stabilisation units, acid gas removal units and core deep NGL recovery units, as well as the switch station.

    Tecnimont’s parent company, Maire, said its scope of work on the RGD phase three project includes EPC activities for the fifth NGL fractionation unit, which will separate the various hydrocarbon components, in addition to treatment and sweetening systems to remove impurities and ensure product quality.

    The contract scope also includes a regeneration gas treatment unit, a propane refrigeration system, ancillary systems and storage facilities. Once completed in 2030, the plant will have an output capacity of 23,000 tonnes a day, or about
    8 million tonnes a year, Milan-headquartered Maire said.

    Adnoc Gas also reiterated its $5bn capex for the first phase of the RGD scheme, which is under construction. The company awarded $5bn in engineering, procurement and construction management contracts in three tranches for phase one of the RGD in June 2025, marking its largest-ever capital investment in a single project.

    Across all three phases, Adnoc Gas has made a total investment of $13.2bn in the RGD programme.

    Capacity expansion

    Saudi Aramco spent $7.7bn on EPC contract awards on the Fadhili gas processing plant expansion in 2024. The project is set to increase the Fadhili gas plant’s processing capacity from 2.5 billion cubic feet a day (cf/d) to up to 4 billion cf/d through the addition of three processing trains, each with a capacity of 500 million cf/d.

    Following its significant capex on the Fadhili expansion, the Saudi energy giant is moving ahead with contract awards this year for various EPC packages under a wider project to boost gas compression capacity at the Shedgum and Uthmaniyah processing plants in the Eastern Province.

    The two plants currently receive about 870 million cf/d and 1.2 billion cf/d of Khuff raw gas, respectively. Through the multibillion-dollar project, Aramco aims to increase their compression and processing capacity and build new pipelines to improve gas transportation.

    Aramco has divided the scope of work on the Shedgum and Uthmaniyah gas compression project into nine EPC packages. It awarded the Uthmaniyah gas compression plant package to locally based Saipem Nasser Saeed Al-Hajri Contracting Company (SNSH), a joint venture of Italian contractor Saipem and local contractor Nasser Saeed Al-Hajri & Partners Company for Contracting.

    The SNSH contract is estimated at $1.24bn, with EPC works on the package scheduled to start in August. Separately, Milan-headquartered Saipem said its share of the contract is worth €900m ($1.04bn), with the EPC works scheduled to run for 42 months.

    Earlier this year, Aramco also awarded the package related to early works and site preparation to local firm Al-Shalawi International Company Trading & Contracting.

    The Shedgum and Uthmaniyah gas compression project will support Aramco’s target of increasing gas production and processing capacity by 80% by 2030, from a 2021 baseline.

    In Oman, PDO also moved ahead this year with a project to expand the Birba gas station in Dhofar Governorate. Known as the Budour-Northeast Birba integrated project, it will add units to enable the station to process additional volumes of sour gas.

    PDO awarded the EPC works on the project to Egypt’s Engineering for the Petroleum & Process Industries (Enppi), with the contract valued at $355m.

    Future pipeline

    Looking ahead, the Mena region has a gas processing pipeline worth at least $10.5bn, with planned projects in Oman, the UAE, Saudi Arabia, Kuwait, Iraq, Libya and Algeria at various stages of development.

    Aramco is expected to award the EPC contract for the other main component of the Shedgum and Uthmaniyah gas compression project, the Shedgum gas compression package, later this year, after several weeks of discussions with bidders.

    The project operator is also in advanced negotiations with frontrunners for the project’s two main pipeline packages and is expected to issue the EPC contracts in the third quarter of this year.

    Meanwhile, state energy conglomerate OQ Group is planning to build an NGL facility at Saih Nihayda in central Oman that will extract condensates and transport them to Duqm on the sultanate’s Arabian Sea coast for fractionation and export.

    OQ plans to deliver the project using a front-end engineering and design-to-EPC model and is in the process of evaluating the proposals it has received from shortlisted contractors. A main contract award is expected by the end of this year.

    Adnoc Gas is expected to re-emerge as a top spender on gas processing when it takes a FID on its estimated $8bn Bab gas cap development project.

    The project aims to build a gas processing plant and associated pipeline networks and ancillary units in the Bab area, about 170 kilometres from the city of Abu Dhabi. The planned facility will process up to 1.85 billion cf/d of additional raw gas once Adnoc Gas’ parent company, Adnoc Group, starts production from the onshore Bab gas cap reservoirs.

    Adnoc Gas has divided the EPC scope on the Bab gas cap development project into four main packages, which are in different stages of tendering.

    Regional gas processing capex is likely to remain robust through the remainder of the decade as NOCs seek to meet growing domestic demand, support industrial development and improve the efficiency of their gas networks.

    Further awards are expected for gas treatment trains, sulphur units, NGL recovery, gas compression and pipeline infrastructure, particularly where projects support petrochemical integration, reduce flaring and increase domestic gas supplies.
