Taqa Water Solutions to launch TSE plant project
18 September 2024

Taqa Water Solutions, formerly Abu Dhabi Sustainable Water Solutions, is reviewing a previous plan to procure an advanced treated sewage effluent (TSE) plant that has an initial design capacity of 750,000 cubic metres a day (cm/d).
A plan to procure the project could be launched in line with the emirate's circular carbon economy push, Nader Assad Bin Taher, chief operating officer of Taqa Water Solutions, told MEED on the sidelines of the ongoing World Utilities Congress in Abu Dhabi.
He said that the process is under way to finalise the way forward for the project, which might eventually have a bigger capacity than initially planned.
MEED understands that the final procurement model for the project is also being discussed.
MEED reported in February 2023 that five companies and consortiums had submitted bids for the engineering, procurement and construction contract.
Among those that submitted proposals for the contract on 23 January were Spain's Acciona, UAE-based Tecton Engineering, and a team comprising Spanish contractor Abengoa and local contracting company Emarat Aloula.
It is understood that the project has been put on hold following the expiry of bid bonds.
The initial plan entailed a TSE plant that is expected to have a design capacity of 700,000 cm/d, with the potential to expand this capacity to 950,000 cm/d in a subsequent phase, as MEED reported.
The TSE facility will produce water for higher-end applications compared to TSE produced in a standard sewage treatment plant.
Twelve individual companies and teams were prequalified to bid for the contract in 2022. They were:
- Abengoa (Spain)
- Acciona (Spain)
- Aqualia (Spain)
- Aquatech (local)
- Hydropower / BEWG (Germany)
- Metito / GCC
- Six Construct (local) / Veolia (France)
- Sepco 3 (China)
- Tecnicas Reunidas (Italy)
- Tecton (local)
- VA Tech Wabag (India)
- Orascom (Egypt) / Cobra (Spain)
The scheme is one of the first major water treatment projects to be launched in Abu Dhabi in recent years.
Canada’s Stantec is the project’s technical consultant.
Bin Taher also confirmed that the bid evaluation process is under way for smaller TSE polishing plant in Abu Dhabi. Located in Khalifa Industrial Zone Abu Dhabi (Kizad), the plant has a capacity of 25 million litres a day, or about 25,000 cm/d.
Abu Dhabi National Energy Company (Taqa) announced the completion of its agreement to acquire Sustainable Water Solutions Holding Company (SWS Holding), formerly Abu Dhabi Sewerage Services Company, for AED1.7bn ($463m), earlier this month.
SWS Holding is the sole entity responsible for wastewater collection and treatment, as well as the production of recycled water in Abu Dhabi.
Taqa announced the rebranding of the company as Taqa Water Solutions in mid-September.

Chinese firm announces $1.9bn Abu Dhabi renewables contract23 March 2026
China Power Construction Corporation (PowerChina) has announced details of a contract signed for the engineering, procurement and construction (EPC) works on part of Abu Dhabi’s $6bn round-the-clock solar and battery storage project.
The independent power project (IPP) will combine 5.2GW of solar photovoltaic (PV) capacity with 19GWh of battery storage. Last October, Emirates Water & Electricity Company (Ewec) and Abu Dhabi Future Energy Company (Masdar) broke ground on what will be the world’s largest combined solar and battery energy storage system (bess), designed to supply 1GW of round-the-clock power.
India’s Larsen & Toubro and Beijing-headquartered PowerChina were awarded the EPC contract for the project last year, with PwC Middle East advising Ewec on financial structuring.
According to the Chinese firm, the full project has been divided into two blocks, north and south, indicating at least two major packages.
PowerChina’s contract, valued at about $1.9bn, covers the northern block of the project, which includes 2.1GW of DC-side PV installations and a 7.75GWh bess. The scope includes the design, procurement and construction of substations, PV facilities and battery energy storage systems.
Located in the Mshayrif area of Abu Dhabi, the wider project is designed to supply steady delivery of power between April and October each year, the UAE’s peak electricity demand season due to cooling loads.
This includes serving large energy users that require 24/7 clean electricity, such as fast-growing data centre operators and technology firms driving artificial intelligence deployment in the region.
Ewec will act as the offtaker under a long-term power purchase agreement.
MEED previously reported that China’s CATL (Contemporary Amperex Technology Co), Jinko Solar and JA Solar will supply the bess and PV modules, with Jinko and JA each providing 2.6GW of modules.
The project will avoid 5.7 million tonnes of CO₂ emissions annually and provide enough clean energy to power nearly half a million homes.
Construction is expected to be completed in 2028.

Kuwait tenders major infrastructure packages23 March 2026

Kuwait’s Ministry of Public Works (MPW) has tendered several contracts for infrastructure works across various parts of the country.
The first tender covers the construction of rainwater drainage systems in the Sabah Al-Ahmad South, Sabah Al-Ahmad, Al-Khairan and Al-Wafra residential areas.
The second tender includes the construction of a treated water system in Kuwait’s southern region.
The third tender covers the construction of a treated water system in Kuwait’s northern region.
The final tender covers the construction of roads, bridges, stormwater drainage, sewage and other services for a section of the Kabd-Sulaibiya Road, as well as a section of the Kabd-Sulaibiya industrial road link.
MPW issued all of these tenders on 22 March, with a bid submission deadline of 21 April.
UK analytics firm GlobalData expects Kuwait’s construction industry to grow by 5.1% in 2026-29, supported by government investment in the oil and gas sector aimed at raising production, as well as investment in the infrastructure sector.
In the short term, growth will be boosted by planned expenditure under the 2025-26 budget, which was approved in March 2025.
The construction industry in Kuwait is expected to record an annual average growth rate of 4.9% in 2026-29, supported by investments in renewable energy, transport, and oil and gas projects.
The commercial construction sector is expected to grow by 4.8% in 2026-29, supported by public and private sector investment in the construction of hotels, retail outlets and office buildings.

Qiddiya tenders new infrastructure package23 March 2026

Saudi Arabian gigaproject developer Qiddiya Investment Company (QIC) has tendered a contract inviting firms to bid for new infrastructure works in Qiddiya Entertainment City.
The scope covers two infrastructure development packages in District 0 of Qiddiya Entertainment City, including the construction of four event park-and-ride facilities.
The tender was issued on 11 March, with a bid submission deadline of 22 April.
Lebanese firm Dar Al-Handasah and Saudi-based Sets International are serving as project consultants.
QIC is accelerating plans to develop additional assets at Qiddiya City. Earlier this month, the company set a 16 April deadline for firms to submit prequalification statements for the Qiddiya high-speed rail project in Riyadh.
Previously, MEED reported that QIC had received bids from contractors on 23 February for a SR980m ($261m) contract covering the construction of staff accommodation at Qiddiya Entertainment City.
The project will cover an area of more than 105,000 square metres (sq m).
Last month, QIC started the main construction works on its performing arts centre at Qiddiya Entertainment City.
The Qiddiya City performing arts centre is one of several major projects within the greater Qiddiya development. Other projects include an e-games arena, Prince Mohammed Bin Salman Stadium, a motorsports track, the Dragon Ball and Six Flags theme parks, and Aquarabia.
In December last year, QIC officially opened the Six Flags theme park to the public.
The theme park covers an area of 320,000 sq m and features 28 rides and attractions, 10 of which are thrill rides and 18 designed for families and young children.
The Qiddiya project is a key part of Riyadh’s strategy to boost leisure tourism in the kingdom. According to UK analytics firm GlobalData, leisure tourism in Saudi Arabia has experienced significant growth in recent years.
The kingdom’s tourism sector posted record-breaking numbers last year, with over 130 million domestic and international visitors entering the kingdom, representing a 6% increase over 2024.

Kuwait’s Mina Al-Ahmadi refinery attacked23 March 2026
Register for MEED’s 14-day trial access
Several units were shut down at Kuwait’s largest oil refinery after it was hit by drones as Iran targeted energy infrastructure across the Gulf, according to a statement from state-owned Kuwait Petroleum Corporation (KPC).
Fires broke out across multiple units at the Mina Al-Ahmadi refinery in the morning of 20 March 2026 following the attack.
The refinery normally processes about 730,000 barrels of oil a day.
There were no casualties as a result of the attack, according to KPC.
Kuwait’s oil and gas sector has been severely disrupted by the ongoing regional conflict.
On 10 March, MEED revealed that the state-owned upstream operator Kuwait Oil Company (KOC) was operating with just 30% of its total workforce in their normal workplaces.
Earlier in the month, KPC also declared force majeure due to difficulties transporting oil and gas through the Strait of Hormuz caused by the conflict.
Force majeure, a French term meaning “superior force”, is a clause included in many international commercial contracts. It allows companies to suspend contractual obligations when extraordinary events occur beyond their control.

Iraq declares force majeure on foreign-operated oil fields23 March 2026
Register for MEED’s 14-day trial access
Iraq has declared force majeure on all oil fields developed by foreign oil companies as the US and Israel’s war with Iran disrupts navigation through the Strait of Hormuz.
The initial attack and Iran’s response have slashed Iraq’s exports.
Prior to the war starting on 28 February, Iraq was exporting between 3.3 and 3.5 million barrels a day of crude oil.
Oil sales account for nearly 90% of Iraq’s government revenues.
Earlier this month, two drone strikes hit infrastructure at Iraq’s Majnoon oil field, increasing security concerns in the country’s energy sector.
One of the drones hit a communications tower, and the other hit the office of the US engineering company KBR.
There were no casualties as a result of the attacks.
Foreign workers were evacuated from the site days after the US and Israel’s war with Iran started, and only Iraqi staff are currently working at the site.
Shortly before the war started, KBR announced that it had been awarded a “major contract” by Iraq’s state-owned Basra Oil Company to provide integrated field management services for the Majnoon oil field.
