Oman awards $186.5m sewer network packages

22 October 2024

Oman's Nama Water Services has awarded several contracts with a total combined value of $186.5m for the construction and development of packages of a sewer network catering to Muscat.

The B7A contract to build a sewer network comprising a main trunk sewer and pumping station in South Azaibah in the Muscat Governate has been awarded to the local United Gulf Construction Company, which offered to build the project for $54.5m.

Nama Water Services tendered the contract in September last year. In addition to the supply and installation of pumping stations, the scope includes the construction of a 3.5-kilometre (km) gravity sewer network and property and house connection chambers.

Nama Water Services awarded a second contract – C13 Package C4 – worth $30m to the local firm Target. The main scope includes the construction of a 16km gravity sewer network with diameters ranging from 200 millimetres (mm) to 600mm in Oman's Seeb catchment. It also includes the construction of about 265 gravity sewer manholes.

Cairo-headquartered Arab Contractors won a $35m contract to construct a sewer network at the C5A and C5B areas in the Aseeb catchment in Muscat.

C5A involves the construction of a 35km gravity sewer network with diametres of 200mm-900mm and 420 gravity sewer manholes. 

C5B entails the construction of a 32km gravity sewer network with similar diametres to C5A, and a further 375 sewer manholes.

Nama Water Services awarded a fourth contract to Target. Valued at $67m, it involves the construction of sewer network B7D, as part of the Bausher sewer infrastructure at Al-Ansab in Oman.

The main project scope involves the construction of a 75km gravity sewer network, 103km of property and house connection chambers and a pump station.

  • Public Investment Fund backs Neom

    16 April 2026

    Saudi Arabia’s Public Investment Fund (PIF) has backed Neom by including it as one of six strategic ecosystems in its newly approved 2026-30 strategy.

    The future of the $500bn gigaproject had been thrown into doubt following the postponement of the 2029 Asian Winter Games at the Trojena mountain resort, the cancellation of construction contracts – such as the $5bn deal with Italian contractor Webuild for dam works at Trojena – and the slowdown of development at The Line, where tunnelling contracts were cancelled and staff left the project.

    The backing comes as Neom’s operational focus appears to be evolving in response to shifting regional dynamics and global economic conditions. For example, on 15 April Neom posted on its official X account about a new Europe-Egypt-Neom-GCC corridor, describing it as a faster route for time-sensitive goods. It said the corridor combines trucking and ferry services to move goods quickly into the Gulf, adding that importers from several European markets are already using it to reach the UAE, Kuwait, Iraq, Oman and beyond.

    Powered by Pan Marine, DFDS and regional RoPax services, the initiative is positioned as a way to add flexibility and resilience to regional supply chains. This emphasis on logistics and immediate trade utility suggests a shift away from the more speculative architectural announcements that characterised Neom’s early years, towards activity more directly tied to current market realities.

    PIF’s broader 2026-30 strategy places heavy emphasis on “delivering competitive domestic ecosystems to connect sectors, unlock the full potential of strategic assets, maximise long-term returns and continue to drive the economic transformation of Saudi Arabia”.

    The inclusion of Neom as a standalone ecosystem within the Vision Portfolio suggests that while the project remains part of the kingdom’s Vision 2030 goals, it will be subject to the fund's focus on working with the private sector.

    That means the long-term success of Neom will increasingly depend on its ability to attract external investment and function as a viable economic hub rather than just a state-funded construction site.

  • Kuwait gas project worth $3.3bn put on hold

    16 April 2026

     

    State-owned Kuwait Gulf Oil Company’s (KGOC’s) planned tender for the development of an onshore gas plant next to the Al-Zour refinery has been put on hold due to uncertainty created by the US and Israel’s war with Iran, according to industry sources.

    The project budget is estimated to be $3.3bn, and the last meeting with contractors to discuss the project took place in Kuwait on 10 February.

    Previously, it was expected to be tendered in late March, but the tendering process was delayed due to the regional conflict and disruption to shipping through the Strait of Hormuz.

    One source said: “This tender is now effectively on hold while KGOC waits for increased stability in the region before it invites companies to bid for the contract.”

    Under current plans, the plant will have the capacity to process up to 632 million cubic feet a day of gas and 88.9 million barrels a day of condensates from the Dorra offshore field, located in Gulf waters in the Saudi-Kuwait Neutral Zone.

    Ownership of the field is disputed by Iran, which refers to the field as Arash.

    Iran claims the field partially extends into Iranian territory and asserts that Tehran should be a stakeholder in its development.

    It is believed that the Dorra field’s close proximity to Iran will make development difficult due to the current security environment.

    The offshore elements of the project are expected to be especially difficult to protect from attacks from Iran.

    In July last year, MEED reported that KGOC had initiated the project by launching an early engagement process with contractors for the main engineering, procurement and construction tender.

    France-based Technip Energies completed the contract for the front-end engineering and design.

  • Iraq pushes to revive oil pipeline through Saudi Arabia

    16 April 2026

    Iraq is pushing to revive an oil pipeline that passes through Saudi Arabia, allowing it to diversify export routes.

    Saheb Bazoun, a spokesman for Iraq’s Oil Ministry, said the pipeline would help to insulate Iraq from any future blockades of the Strait of Hormuz, which has been largely closed since 28 February.

    The original pipeline through Saudi Arabia has not been used for more than 30 years and would need work to be done in order to bring it online.

    It is 1,568km long, extending from the city of Zubair in Iraq to the Saudi port of Yanbu on the Red Sea.

    The pipeline was built in two phases during the 1980s. The first phase stretches between Zubair and Khurais, while the second extends to Yanbu. The pipeline’s operating capacity reached over 1.6 million barrels a day (b/d).

    Following the Gulf War, the pipeline was shut down in August 1990. It has remained out of operation for decades, despite Iraq’s several attempts to restart it.

    The original pipeline project cost over $2.6bn, including storage tanks and loading terminals.

    In the wake of the US and Israel attacking Iran on 28 February, global markets have lost 11 million barrels a day (b/d) of oil supply due to the effective closure of the Strait of Hormuz.

  • Algeria opens bidding for water treatment plant

    15 April 2026

     

    State-owned Cosider Pipelines, part of Algeria’s public infrastructure group Cosider, has issued a tender for the construction of a demineralisation plant in In Salah in Algeria.

    The contract covers the design, supply, installation, testing and commissioning of a plant with a treatment capacity of 62,000 cubic metres a day (cm/d).

    The tender is open to local and international companies specialising in the design and construction of demineralisation and reverse osmosis desalination plants.

    The bid submission deadline is 26 April.

    The project will be located at In Salah, a key industrial area in southern Algeria, where treated water supply is important for both municipal and industrial use.

    Cosider said that individual bidders must demonstrate that they have completed at least one reverse osmosis demineralisation or desalination plant with a capacity of 20,000 cubic metres a day or more.

    They must also show an average annual turnover of at least AD1bn ($7.7m) for their five best years over the past decade.

    For consortium bids, all partners must share full responsibility for the contract, while the lead company must meet the technical and financial requirements.

    Recent projects

    In 2023, MEED reported that Riyadh-based water utility developer Wetico had won two contracts to develop water desalination plants in Algeria.

    Societe Algerienne de Realisation de Projects Industriels (Sarpi) awarded the contract for the El-Tarf desalination plant, while Entreprise Nationale de Canalisations (Enac) is the client for the Bejaja facility.

    Both plants were commissioned in 2025, each with a production capacity of 300,000 cm/d.

    Separately, Wetico was the main contractor on a third plant commissioned last year. The Cap Dijinet 2 seawater desalination plant in Boumerdes province covers 18 hectares and also has a capacity of 300,000 cm/d.

    Like many countries, Algeria is facing pressure on resources due to longer and more frequent droughts. Seawater desalination is seen as a key driver of the government’s strategy to guarantee drinking water supply.

    According to previous reports, the government is planning to build up to six additional plants by 2030.
