Abu Dhabi to tender Project Wave phase two in 2024

30 October 2023

Abu Dhabi National Oil Company (Adnoc) and Abu Dhabi National Energy Company (Taqa) are expected to start the tendering process for the Al-Nouf seawater treatment plant and water collection and distribution network project in the second half of 2024.

It is the second public-private partnership (PPP) phase of Project Wave, which will replace the current aquifer water injection systems used to maintain reservoir pressure in all onshore oil fields in Abu Dhabi.

According to a source close to the project, the tender could be issued to qualified developers between the middle and end of 2024.

Like the first-phase Mirfa seawater treatment plant, the Al-Nouf facility will be developed and maintained as a build-own-operate-transfer (BOOT) project. 

The $2.2bn Mirfa water treatment plant reached financial close in September.

Adnoc and Taqa awarded the 30-year BOOT contract for the Mirfa scheme to a team of Egypt's Orascom Construction and Metito in May this year.

Adnoc and Taqa will hold a joint majority stake of 51 per cent in the project company, while the developer consortium will hold the remaining 49 per cent.

The Orascom-Metito team will develop and operate the facilities to treat and supply seawater for Adnoc's operations at the Bab and Bu Hasa fields in Abu Dhabi.

The Mirfa plant package involves the development of a nanofiltration plant with a capacity of 115 million imperial gallons a day (MIGD) in Mirfa.

The package also includes the plant's seawater intake and outfall facilities, two pumping stations, a 75-kilometre water transmission pipeline and 230 kilometres of distribution pipelines to the Bab and Bu Hasa oil fields.

The project is expected to reduce the water injection-related energy consumption of the oil fields by up to 30 per cent.

Orascom, Metito and Egypt's Petrojet will undertake the engineering, procurement and construction (EPC) works for the project. 

Aquifer injection system

Project Wave aims to utilise seawater as an additional source for enhanced oil recovery-based injection into Abu Dhabi's onshore fields.

The Mirfa and Al-Nouf facilities were initially expected to have a total combined treatment capacity of about 210MIGD. This is understood to have been expanded.

Adnoc will be the sole offtaker of the treated seawater at the battery limit of the Adnoc Onshore fields.

A team of UK-based Alderbrook Finance and Saudi Arabia-based SMBC are the financial advisers to the client for the BOOT projects. Austria-headquartered ILF Consulting Engineers is the technical adviser.

In-field distribution 

Engineering, procurement, construction and management (EPCM) work for a third component of Project Wave is under way. 

Adnoc Onshore awarded Greece's Archirodon the EPCM contract for an in-field distribution network to disseminate treated seawater to water injection wells in Adnoc's onshore oil fields.

The EPCM contract will cover the replacement of an existing water injection infrastructure with a new treated seawater injection network, as well as the installation of sub-adits.

The contract awarded to Archirodon is for three years, with the client expected to tender the EPC work at some point during the duration of the contract.

  • Veolia wins Jordan water services contract

    18 February 2026

    Register for MEED’s 14-day trial access 

    France's Veolia has signed a four-year performance-based management contract with the Water Authority of Jordan to support water and wastewater services in the country’s northern governorates.

    Under the contract, Veolia will provide operations, maintenance and management services to Yarmouk Water Company, the public utility responsible for water supply and wastewater services in the region.

    The agreement covers Irbid, Jerash, Ajloun and Mafraq, an area spanning nearly 30,000 square kilometres and covering about 3 million people.

    The scope includes water and wastewater operations, maintenance, billing and collection, and customer service.

    According to the firm, the performance-based structure prioritises measurable improvements, including service delivery, cost efficiency and revenue management.

    The company said it will deploy technical and management specialists to support operations, rehabilitation works and investment initiatives.

    The contract builds on Veolia’s existing operational role in Jordan’s water sector. The company operates the Disi-Amman scheme, which supplies about 100 million cubic metres of drinking water a year, under an operations and maintenance contract.

    It also operates the Al-Samra wastewater treatment plant, which produces about 133 million cubic metres of treated wastewater annually for agricultural reuse.

  • SAR tenders phosphate rail project management deal

    18 February 2026

     

    Register for MEED’s 14-day trial access 

    Saudi Arabian Railways (SAR) has floated another tender inviting firms to bid for a contract covering the project management consultancy services for its Phosphate 3 rail programme.

    The tender was issued on 15 February with a bid submission deadline of 5 April.

    The contract duration is 54 months.

    The latest tender follows SAR floating a multibillion-riyal tender to double the tracks on the existing phosphate transport railway network connecting the Waad Al-Shamal mines to Ras Al-Khair in the kingdom’s Eastern Province.

    The tender – covering the second section of the track-doubling works, spanning more than 150 kilometres (km) – was issued on 9 February. The bid submission deadline is 15 April.

    Earlier this month, MEED reported that SAR received bids from contractors on 1 February for the project’s first phase, which spans about 100km from the AZ1/Nariyah Yard to Ras Al-Khair.

    The scope includes track doubling, alignment modifications, new utility bridges, culvert widening and hydrological structures, as well as the conversion of the AZ1 siding into a mainline track.

    The scope also covers support for signalling and telecommunications systems.

    The tender notice was issued in late November with a bid submission deadline of 20 January.

    Switzerland-based engineering firm ARX is the project consultant.

    MEED understands that SAR is expected to tender a total of four packages for the phosphate railway line.

    The other packages expected to be tendered shortly include the depot and the systems package.

    In 2023, MEED reported that SAR was planning two projects to increase its freight capacity, including an estimated SR4.2bn ($1.1bn) project to install a second track along the North Train freight line and construct three new freight yards.

    Formerly known as the North-South Railway, the North Train is a 1,550km-long freight line running from the phosphate and bauxite mines in the far north of the kingdom to the Al-Baithah junction. There, it diverges into a line southwards to Riyadh and a second line running east to downstream fertiliser production and alumina refining facilities at Ras Al-Khair on the Gulf coast.

    Adding a second track and the freight yards will significantly increase the network’s cargo-carrying capacity and facilitate increased industrial production. Project implementation is expected to take four years.

    State-owned SAR is also considering increasing the localisation of railway materials and equipment, including the construction of a cement sleeper manufacturing facility.

    Register for MEED’s 14-day trial access 

    Saudi Arabia's Smart Accommodation for Residential Complexes Company (Sarcc) has signed an agreement with Riyadh-based Mawref Company to develop a 12,000-bed worker accommodation project in North Riyadh.

    The project will cover about 120,000 square metres (sq m), with a total built-up area of 150,000 sq m.

    The development is expected to cost over SR669m ($178m), with the first phase slated for completion in 2029.

    Sarcc is backed by the Public Investment Fund (PIF), the Saudi sovereign wealth vehicle.

    The agreement follows Sarcc signing another agreement in September last year with privately-owned local firm Tamimi Global Company to explore collaboration in developing worker accommodation facilities in the kingdom.

    The PIF launched Sarcc in October 2024 with the aim of developing and operating staff housing and accommodation assets in the kingdom.

    Sarcc will develop and operate the staff accommodation facilities at major construction projects in Saudi Arabia.

    The company will seek opportunities to invest in the sector to strengthen staff housing standards. Sarcc will also look to engage the private sector by enabling investment and partnership opportunities in sectors including construction, catering, transportation and retail.
