• On the occasion of the visit to France of the Head of State of the Sultanate of Oman, His Majesty Sultan Haitham bin Tariq, the Oman Water and Wastewater Services Company S.A.O.C. (NAMA Water Services) announced it has granted SUEZ and its partners, National Trading Company L.L.C. and National Energy Center S.A.O.C., a Performance-based Contract to provide water and wastewater services to the capital of the Sultanate Muscat, the North Sharqiyah and South Sharqiyah Governorates (Cluster 1).
• This 15-years contract, for a total amount of 2 billion euros, will cover the Operation and Maintenance of water and wastewater assets and services for 2.3 million inhabitants, equivalent to 43% of the population of the Sultanate of Oman. It also includes a water loss reduction target to meet the highest international standards.

​Xavier Girre, CEO of SUEZ, said: “It is an honor for SUEZ to collaborate with the Omani authorities to provide sustainable drinking water and sanitation services to more than 2 million people. This is also a great source of pride as it is the largest contract ever awarded to SUEZ in the Middle East, illustrating the strong momentum of our development in the region. This success reflects the recognition of SUEZ teams’ expertise in addressing critical water challenges in a context of structural water stress.”

Providing effective and sustainable water and wastewater services to the Omani population

• As Oman faces economic growth and rising demand, ensuring effective and sustainable water management is a major priority for the country’s future. The Omani authorities aim to address these challenges, in the ‘Vision 2040’ strategy, by reducing costly water losses and implementing performance-driven practices to improve operational efficiency. They also aim to ensure workforce stability and enhance the long-term attractiveness of the Omani water sector by accelerating capacity building and knowledge transfer.
• To achieve these objectives, the national water company NAMA Water Services is implementing a new Performance-based Contract, in line with international best practices, to provide water and wastewater services throughout Muscat and the North Sharqiyah, and South Sharqiyah Governorates (Cluster 1), the most populous region of the country, with 2.3 million inhabitants.

The scope of the contract, drawn on SUEZ’s expertise, will cover both:

• Water services with the operation and maintenance of 240 wells and 10,700 km of pipelines to distribute 470,000 m³/day of drinking water. It also covers the refurbishment and upgrading of 4 desalination plants and the operation of more than 400 000 smart meters.
• Wastewater services with the operation and maintenance of 22 wastewater treatment plants, representing a total treatment capacity of 280,000 m3/day, around 3,000 km of sewer networks, and 400 km of treated effluent networks delivering treated water for reuse, and installation and operation of new wastewater house connections.

Combining global expertise and local capabilities to deliver measurable and sustainable performance
This performance-based contract comprises 33 key performance indicators to ensure the sustainable operation and delivery of high-quality water services, that will determine the operators’ remuneration. These KPIs include:

• Reduce water losses from 34% to 11% by 2040
• Guarantee a high-quality, 24-hour water supply
• Carry out optimized preventive maintenance activities to improve service reliability and extend asset lifespan

These service improvements rely on SUEZ’s proven practices, along with the implementation of the Group’s technologies and digital solutions: Aquadvanced to monitor plants and networks, optimize performance and reduce energy and chemicals consumption; Inflowmatics and iDroloc to ensure advanced leak detection and Sewerball to enable rapid detection of water pollution or infiltration in sanitation networks.

Beyond technologies, the success of the project relies on the expertise of the Omani teams. A comprehensive capacity-building programme, drawing on international expert knowledge, has been designed to develop operational and managerial skills over the long term. The performance-based contract involves strong commitment to omanization (>83%) and In Country Value¹, supporting the Government's strategic goals of Oman Vision 2040.

A shared governance between NAMA Water Services and SUEZ to ensure performance services
In this partnership, NAMA Water Services retains its strategic and regulatory role of supervision and governance, while the Consortium will be responsible for day-to-day operations, through the dedicated company National Sustainable Water Alliance L.L.C:

NEC will play a central role in driving smart utility technologies, digital transformation initiatives, advanced metering infrastructure, operational optimization and performance enhancement programs throughout the contract.
