Veolia was distinguished in the following categories:
- Industrial Desalination Plant of the Year (Marafiq project)
- Water / Wastewater Project of the Year (Antarctica project)
- Municipal Desalination Plant of the Year (Az Zour North 1 project)
Although these Awards showcase Veolia’s international projects, Veolia Water Technologies in South Africa has developed similar local projects using the same technologies! Read more about these below!
Marafiq SWRO, Saudi Arabia - Industrial Desalination Plant of the Year
What is it? A 178 000 m³/d seawater reverse osmosis plant serving the Sadara Chemical Company’s massive manufacturing facility in the industrial city of Jubail, on the Gulf coast of Saudi Arabia. The facility reached full commercial operation in 2016.
Who is involved? The plant is owned and operated under a 20-year build-own-operate contract by Marafiq, the power and water utility company for the cities of Jubail and Yanbu. The offtaker for the water is Sadara, the Dow/Aramco joint venture based in Jubail. The plant was built by Veolia, which also supplied the DAF pre-treatment system. UF membranes were supplied by Pentair and RO membranes by Dow. ERI supplied energy recovery systems.
What makes it special?
- The delivery of the project through a dedicated single-user build-own-operate contract leverages the financial strength of a secure utility to guarantee a supply of high-quality water on a performance-linked basis. The choice of contract structure demonstrates a high degree of confidence in Marafiq as a reliable provider of utility services.
- The site deploys an array of high-end pre-treatment technologies – dissolved air flotation followed by self-cleaning microfiltration and ultrafiltration stages – to allow the plant to handle large volumes of water from a feed source at the extreme reaches of salinity and temperature for a desalination plant.
- The installing of a unique dual-train SWRO-then-BWRO process allows for a water recovery level approaching 50%, while a rotary isobaric pressure exchanger gives a specific power consumption of just 5.1kWh/m³, an impressive achievement for a plant of this scale dealing with hostile feedwater conditions.

Antarctic Reuse Project - Water / Wastewater Project of the Year
What is it? A multi-year programme to clean up contamination in the Antarctic. The project included landfill leachate treatment, remediating historical diesel spills, and culminated in 2016 with the installation of an MBR facility and the piloting of an advanced water treatment plant.
Who is involved? Veolia has been a long-term partner of the Australian Antarctic Division and the Australian Water Recycling Centre of Excellence, working with TasWater and Coliban Water, as well as two universities in Victoria. Xylem supplied the ozone and UV equipment for the advanced water treatment plant, which also employs Metawater’s ceramic MF membranes, a Dow RO system, and instrumentation from Hach and Wallace & Tiernan. Martin Membrane Systems supplied the MBR plant, while AECOM provided technical assistance.
What makes it special?
- The Antarctic is one of the world’s harshest yet most precious environments, with unique contaminant dispersal challenges. The sustained 15-year commitment to clean up historic pollution while using cutting-edge technology to provide fresh water to the dedicated research community is a shining example of how science and nature can work together for the greater good.
- An MBR plant commissioned in 2016 will be complemented by a seven-barrier advanced water treatment plant at the Davis research station, which brings the capability to produce world-class potable water from secondary effluent within a closed-loop system. The plant was rigorously pilot-tested in Tasmania prior to shipping it to the Antarctic, where it will operate in a temperature-controlled environment.
- The environmental benefit of the programme is not its only lasting legacy – the concurrent risk framework developed by Veolia, Coliban Water and the University of Melbourne around chemicals of concern has the potential to revolutionise mainstream water utilities’ sampling protocols, whilst significantly lowering infrastructure operating costs.

Az-Zour North 1, Kuwait – Municipal Desalination Plant of the Year
What is it? A 486 400 m³/d multiple effect distillation plant in Kuwait. The first privately owned desalination plant in the country, it forms the water desalination element of the first stage of the Az-Zour North independent power and water project.
Who is involved? The desalination plant was delivered by EPC contractor Sidem (Veolia) on behalf of the plant’s owner, a consortium comprising Engie (17.5%), Sumitomo (17.5%), A.H. Al-Sagar & Brothers (5%) and the Kuwaiti government (60%). Water is supplied to Kuwait’s Ministry of Energy and Water.
What makes it special?
- By showcasing the very pinnacle of what MED has to offer, the contractor delivered a massive asset that requires a minimum of handling. Combining low O&M costs with a limited requirement for scaling treatment, the plant allows its owners to push the margins of performance and profitability – a key condition for the country’s pathfinder water PPP.
- The plant redefines efficiency in thermal desalination. An ultra-low electrical consumption of around 1 kW h/m3 keeps its reliance on external power sources to a minimum. Sidem’s in-house MED expertise allows the plant to use relatively low-pressure steam, freeing up energy and resources at the attached power facility.
- The location of the plant meant it had to be configured to handle extreme levels of seawater salinity and a wide range of feedwater temperatures ranging from 13°C to 38°C. The delivery of a truly flexible plant of this size is a stunning paean to engineering excellence.
Did you know? Thermal desalination is used only in countries where the cost of energy is much lower, or free, in some cases, such as most oil-rich countries. Its infrastructure is also more expensive to build. Therefore, Veolia Water Technologies in South Africa utilises more cost-effective reverse osmosis desalination technologies in its desalination plants, we have constructed seven reverse osmosis plants in South Africa, including Mossel Bay (the country’s largest), Cannon Rocks, Lamberts Bay, Plettenberg Bay and Knysna.
