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.

  • Aramco extends deadline for Ras Tanura refinery gas pipeline

    1 July 2026

     

    Saudi Aramco has granted contractors more time to prepare bids for a tender to replace a pipeline in the Gas Line Abqaiq–Ras Tanura (GART) transmission network.

    The GART grid transports associated gas and natural gas liquids (NGL) from the Abqaiq oil processing complex as feedstock, northwards to the Ras Tanura refinery in Saudi Arabia’s Eastern Province.

    The aim of the project is to replace the GART-22 pipeline that connects the Juaymah export terminal on the Gulf coast in the Eastern Province to the Ras Tanura refinery, to ensure reliable fuel gas supply and meet ongoing demand.

    The basic scope of work for the project is to install a new 24-inch pipeline system to replace the GART-22 line and the abandoned GART-24 line. It will cover a distance of 18 kilometres between Juaymah and the Ras Tanura terminal.

    The scope also includes the installation of associated scraper trap facilities (launcher and receiver), pressure control valves, motor-operated valves and gas detection and sampling systems.

    Aramco issued the tender for the project in May, setting an initial deadline of 30 June for contractors to submit proposals, MEED previously reported.

    The Saudi energy giant has now extended that deadline until 10 July, according to sources.

    The following contractors, among others, are understood to be bidding for the project:

    • ACE Pipeline Arabia
    • Combined Group Contracting Company
    • Gas Arabian Services Company
    • Max Streicher Saudi Arabia
    • National Basics Company
    • Saad Ali Alessa Group
    • Sicim
    • Sinopec Engineering Group Saudi
    • Tecton Engineering & Construction
    Ras Tanura refinery complex

    The Ras Tanura refinery is the oldest, and one of the largest, crude oil refineries in Saudi Arabia. The complex has a refining capacity of 550,000 barrels a day (b/d).

    The facility also has a 305,000 b/d NGL processing facility, a 960,000 b/d crude stabilisation facility, combined steam and gas turbine electrical power generation plants with a summer capacity of 145MW and a winter capacity of 158MW, and a combined 150-pound and 600-pound steam capacity of 6,217 million pounds an hour.

    It has 75 crude oil and products storage tanks with a combined capacity of 5.8 million barrels.

    The Ras Tanura refinery’s major facilities include a 325,000 b/d crude distillation unit, a 225,000 b/d gas condensate distillation unit, a 50,000 b/d hydrocracker and 107,000 b/d of catalytic reforming capacity.

    The facility is Aramco’s only refinery to contain a Visbreaker processing unit, which has a 60,000 b/d capacity.

    The Visbreaker reduces the quantity of residual oil produced in the distillation of crude oil and increases the yield of more valuable middle distillates, heating oil and diesel.

    The refinery complex also produces 17,000 b/d of asphalt, more than any other refinery in Saudi Arabia.

    Ras Tanura receives crude feedstock from the Abqaiq, Safaniya and Manifa oil field developments.

    Crude is typically transferred to Ras Tanura through a pipeline and can also be supplied by ship.

    Most of Ras Tanura’s production is transferred to the Dhahran bulk plant for domestic use, while some products are exported from the nearby Ras Tanura shipping terminal.

  • Siemens Energy to supply turbines for Oman IPP projects

    1 July 2026

    Germany’s Siemens Energy has announced it will supply power generation technology and long-term service agreements for the 2.6GW Misfah and Duqm independent power producer (IPP) projects in Oman.

    The scope includes the supply of six F-class gas turbines, six generators and 20-year long-term service agreements for the equipment.

    The combined-cycle gas-fired plants will add almost 20% to the sultanate’s electricity generation capacity. They are expected to provide electricity to more than two million people.

    Oman’s Nama Power & Water Procurement (Nama PWP) signed power-purchase agreements (PPAs) for the development and operation of the plants in January.

    The two combined-cycle gas turbine plants are being developed by a consortium comprising Korea Western Power (Kowepo), Qatar’s Nebras Power, the UAE’s Etihad Water & Electricity (EtihadWE) and Oman’s Bhawan Infrastructure Services.

    The Misfah IPP will be led by Nebras Power and located in Wilayat Bousher in Muscat Governorate, with a planned capacity of 1,600MW.

    The Duqm IPP will be led by Kowepo and located in Wilayat Duqm in Al-Wusta Governorate, with a capacity of 800MW.

    In May, MEED exclusively reported that a consortium of China-headquartered Shandong Electric Power Construction No. 3 Company (Sepco 3) and South Korea’s Doosan Enerbility had been appointed as the main contractor.

    The gas turbines will have hydrogen co-firing capability, providing flexibility to increase hydrogen use over time, Siemens said in a statement.

    The turbines will be manufactured at Siemens Energy’s facility in Berlin. The generators will be produced at the company’s plant in Muelheim, Germany.

    Register for MEED’s 14-day trial access 

    Saudi gigaproject developer Qiddiya Investment Company (QIC) has awarded an estimated SR4.3bn ($1.1bn) contract for the construction of a racecourse at Qiddiya entertainment city, on the outskirts of Riyadh.

    The contract was awarded to Taj Dhabi, a local subsidiary of UAE-based Trojan Construction.

    The racecourse venue will cover 1.3 million square metres and accommodate 70,000 spectators.

    QIC issued the tender for the construction works in December last year, but formally announced the project only on 10 February. Contractors submitted their bids on 15 February, MEED previously reported.

    According to a statement published on QIC’s website: “The venue will include the region’s first straight-mile turf course, alongside a 2.2 kilometre (km) main turf track and a 2.4km inner dirt track.

    “A 21,000-seat grandstand will anchor the venue, with the ability to expand capacity to up to 70,000 guests through event overlays during major race days,” the statement added.

    A centrepiece of the venue will be a 110-metre central parade ring, located in the middle of the racecourse.

    The project also includes an equine hospital that will provide advanced veterinary services, including diagnostics, surgery, rehabilitation and emergency care for horses.

    The Qiddiya City horse racing venue is one of several major projects within the greater Qiddiya development. Other projects include an e-games arena, the Prince Mohammed Bin Salman Stadium, a motorsports track, a performing arts centre, the Dragon Ball and Six Flags theme parks, and Aquarabia.

    The project is a key part of Riyadh’s strategy to boost leisure tourism in the kingdom. According to GlobalData, leisure tourism in Saudi Arabia has experienced significant growth in recent years.

  • NCP seeks firms for Saudi Arabia university hospital PPP

    1 July 2026

    Saudi Arabia’s Umm Al-Qura University, in collaboration with the National Centre for Privatisation & PPP (NCP), has launched an expression of interest for the completion of the construction and operation of the Umm Al-Qura University Hospital in Mecca.

    Issued to contractors on 30 June, the notice has a submission deadline of 21 July.

    The scope includes completing the remaining construction works, as well as the subsequent operation of the hospital.

    Upon completion, the hospital will have a capacity of 391 beds.

    The project will be delivered as a public-private partnership (PPP) under a design, build, finance, operate and maintain model.

    The contract duration is 30 years.

    The project is the latest healthcare project to be procured on a PPP basis in the kingdom. In June, MEED reported that Saudi Arabia’s Ministry of Health and NCP had awarded a PPP contract for the operation and management of the Sabic Specialised Behavioural Healthcare Hospital in Riyadh.

    That contract was awarded to SEH Healthcare, a consortium comprising local firms Specialised Medical Company (SMC Healthcare) and Health Gates Complex, and Germany’s Dr Ebel Fachkliniken.

    In a filing with the Saudi Exchange (Tadawul), SMC Healthcare said the total estimated project value is about SR3.8bn ($1bn).

    In January, Saudi Arabia launched a national privatisation strategy aimed at mobilising $64bn in private sector capital by 2030.

    Building on the privatisation programme first introduced in 2018, the strategy focuses on unlocking state-owned assets for private investment and privatising selected government services.

    In a statement, NCP said the strategy comprises 147 opportunities drawn from a broader pipeline of more than 500 projects across 18 sectors.
