In Saudi Arabia alone, contract awards worth almost US $154 billion were signed over the course of 2024 – the highest annual tally ever recorded. It underlines Riyadh’s determination to keep capital spending on track despite tighter global money markets and tightening oil prices. And it points to a wider story: drastic changes in the funding mix. Instead of leaning on the sovereign balance sheet, ministries across MENA are looking increasingly to the private sector to help deliver their project programmes.
One lever is the rapid roll-out of public-private partnerships (PPPs). From airports to pipelines, from hospitals to schools, projects are being re-packaged so that private developers design, build, finance and operate assets in partnerships with governments in contract concessions that may span decades. Consider the Saudi Arabian aviation authority’s ongoing Abha International Airport concession, which illustrates the trend. Bidding has been extended to allow international consortia to propose a comprehensive solution, complete with sewage-treatment and renewable-energy components.

Another lever is the use of sovereign and quasi-sovereign credit wraps. The Public Investment Fund, National Development Fund and a network of sector regulators now provide backstops to potential revenue risks. As a result, Saudi Arabia alone carries US $184.6 billion of power-and-water schemes at the bidding stage – the deepest deal pipeline anywhere in the Middle East.[1]
Finally, green-labelled debt is coming of age. Because many assets replace fossil fuel with renewables, they qualify for sustainability-linked loans and bonds. Under Basel III regulations, green exposures receive favorable treatment — allowing banks to strengthen liquidity ratios while securing long-term stable returns.
Altogether, it adds up to a capital toolkit that is broader – and cheaper – than ever before. For investors both inside and outside the region, the opportunities are immense. MENA infrastructure is poised to become the next big success story in international finance.
Where the money is flowing
As a case study in the possibilities from this financial re-engineering, consider MENA’s water sector. The region – not blessed with an abundance of natural freshwater supplies – is brimming with new water desalination, transmission and strategy storage projects, almost all of which will be implemented through the PPP model. It now accounts for the single largest slice of Saudi Arabia’s US $387 billion power-and-water project market. This includes the US $137.5 billion already under construction and a further US $249.5 billion moving through design and tender (also encompassing the US $184.6 billion of power-and-water schemes at the bidding stage cited above).[2]
Awards spiked in 2024, when power-and-water contracts cleared US $68 billion, triple the 2023 total. Digging deeper, the past ten-year ledger shows water pipelines absorbing US $27.6 billion, desalination plants US $14.8 billion and treatment facilities US $11.1 billion. It proves that many investors have already priced in the potential rewards pouring forth from the region, and are moving to capitalise further.
These activity levels are just the start. A sweeping capacity plan released by the Saudi Water Partnership Company (SWPC) – Saudi Arabia’s principal buyer of all produced water from both public and private sectors – is set to turbocharge water sector investment. Desalination capacity is scheduled to reach 8.1 million m³ per day by 2032, driven by coastal clusters such as Rabigh 4 (under construction) and a brace of mega-plants now in Transaction Phase. Waste-water treatment will climb to 2.6 million m³ per day by 2030, supported by a collection network of 11,550 km that threads through every major population centre. And transmission pipelines are being laid at break-neck speed. 1,640 km of new trunk lines – including the landmark Jubail–Buraydah and Riyadh–Qassim concessions – will deliver 2.43 million m³ per day of potable water by 2029. All of above capacity will be executed through the PPP module.
MEED data show that the Jubail–Buraydah pipeline alone carries a CAPEX tag of US $2.27 billion and is already attracting bids from blue-chip developers. On the treatment side, the Al Haer sewage plant is moving through construction tenders at 200,000 m³/d, while desalination’s next wave – Ras al-Khair 2, Al-Rais 2 and Tabuk 1 – is slated to close financing in 2026. The water sector’s momentum is clear, and the attraction for international capital is obvious.
Why Saudi Arabia is setting the pace
The entire MENA region is an international success story in investment innovation over recent decades. Now, however, Saudi Arabia stands out. Scale is the first attraction, with the value of all known, planned and unawarded projects in the pipeline now totalling US $1.57 trillion. Vision 2030 has hard-wired multi-year spending into fiscal planning, insulating infrastructure budgets from commodity price swings.
Investors prize revenue certainty. That is exactly what SWPC provides. As Saudi Arabia’s single bulk water buyer, it is able to cement 25- to 35-year offtake agreements and handle potential hurdles like regulatory uncertainty and currency logistics on behalf of developers. For example, while SWPC pays in Saudi Riyals, the tariffs are denominated in USD at a fixed exchange rate, ensuring long-term currency stability and revenue predictability for international investors. It currently oversees 49 live projects, 10 million m³/day of desalinated output and 600,000 m³/day of treated waste-water – a portfolio large enough to diversify operational risk across plants, geographies and technologies.
Last, the macro backdrop is impossible to ignore. GlobalData estimates suggest Saudi energy-and-utilities construction will grow at an average 5.8% per year between 2025 and 2028, powered by renewables and water infrastructure. MEED lists PPP expansion, net-zero commitments and record FDI targets among the top four drivers of the Gulf project market. Policy, demand and finance are all pulling in the same direction.
Higher interest rates may have made infrastructure finance a harder game worldwide. But the Gulf is writing its own rule-book. By putting innovative capital strategies at the heart to smooth the road ahead for investors, SWPC has already unlocked billions in liquidity for a booming water market. For global investors hunting both scale and resilient cashflows, it is an opportunity that cannot be ignored.
