Market Size and Growth
The market's historical CAGR of 8.90% (2020-2025) reflected steady municipal spending, but the report indicates forecast growth accelerates to 11.30% as service intensity rises from approximately USD 0.400 per cubic meter in 2025 to USD 0.550 by 2031. For investors, revenue growth outpacing contracted-volume growth signals a durable shift toward higher-value, outcome-linked service mix.
Structural Desalination Dependence and Rising Water Demand
Oman sourced approximately 90% of its national water production from desalination in 2025, and the report indicates demand is expected to rise by roughly 3% annually. The new Ghubrah III facility alone adds 300,000 cubic meters per day of planned capacity, expanding the installed base available for long-term service contracts.
Performance-Based Outsourcing of Municipal Operations
The first large municipal cluster contract covers 2.3 million residents, or 43% of the population, spanning 22 wastewater treatment plants and 280,000 cubic meters per day of treatment capacity. It uses 33 operating KPIs and targets cutting non-revenue water from 34% to 11% by 2040, per the report's contract documentation.
Infrastructure Expansion and Reuse Monetization
The report identifies OMR 453.3 million allocated to more than 113 water projects and OMR 212.7 million to more than 112 wastewater projects between 2025 and 2027. Treated-effluent reuse utilization is targeted to increase from 50% to 71%, converting a compliance cost into a contracted industrial and irrigation resource.
Competitive Landscape
Competition centers on concession access, performance guarantees, local consortium formation and the balance-sheet capacity required for multi-year availability commitments across 36 total operators.
Global O&M Specialists
- Companies: SUEZ, Veolia and Metito.
- Strategic Position: These operators combine global desalination and wastewater O&M experience with the balance-sheet strength required to underwrite long-duration availability payments. Their exposure is execution risk on aggressive loss-reduction targets when baseline asset condition data is incomplete.
Regional Engineering and Process Specialists
- Companies: GS Inima and VA Tech WABAG.
- Strategic Position: These operators compete on process engineering depth and regional delivery track record, positioning them well for industrial reuse and mid-scale municipal contracts. Their risk is procurement concentration, since large guarantees and localization obligations favor consortiums with deeper capital access.
Non-Revenue Water Is the Market's Central Pricing Risk
The report identifies high non-revenue water and aging network economics as the most consequential operating risk, with 177.79 million cubic meters of non-revenue water recorded in 2023 against a regulatory target of 10% by 2036.
- Reduction requires coordinated replacement of pipes, meters and district controls, not a single technology deployment, extending payback periods for operators.
- Performance-based contractors carry execution risk when baseline data, asset condition and customer metering are incomplete.
- Lost desalinated water destroys value after energy-intensive production, increasing the cost base carried by utilities and government support mechanisms.
- Operators that invest in digital leak detection and district metering before bidding can price loss-reduction targets more defensibly than competitors relying on legacy baselines.
For contractors and investors, this means technical due diligence on network condition now matters more than headline contract size.
Energy and Marine Operating Risk Compress Fixed-Fee Margins
Reverse-osmosis desalination requires reliable power and optimized pressure management, and the report indicates energy-price or outage volatility can compress operating margins under fixed service fees. Algal blooms and jellyfish intrusions increase pre-treatment loads and can force plant derating.
- Brine discharge standards raise monitoring and treatment obligations as plants scale and coastal carrying capacity tightens.
- The Al Ghubrah facility produced approximately 58.9 million cubic meters in 2025 while maintaining 96.55% plant availability in 2024, a benchmark new entrants must match to win availability-linked contracts.
- Operators with advanced dissolved-air flotation and intake management are better positioned to defend margin during marine fouling events.
- Contractors should price energy volatility explicitly into long-term availability payment structures rather than absorbing it as a fixed cost.
For financial institutions underwriting these contracts, energy-cost pass-through mechanisms deserve as much scrutiny as loss-reduction targets.

Analyst View
The future of this market will be decided by which operators convert loss-reduction and availability targets into predictable margin, not by concession count alone, ahead of the next cluster tenders expected through 2028. Global specialists with strong balance sheets can absorb execution risk on incomplete baseline data that would erode a smaller consortium's margin entirely, and that advantage compounds as more municipal clusters convert to performance-based structures.
Strategic Implications by Stakeholder
- For Operators: Invest in digital leak-detection and asset baselining before bidding, not after contract award.
- For Investors: Weight technical due-diligence depth and energy-cost pass-through terms as heavily as concession tenure.
- For Government Counterparties: Standardize KPI frameworks across clusters to lower bidder uncertainty and widen the qualified consortium pool.
- For Financial Institutions: Structure covenants around verified performance data rather than contracted volume alone.
Strategic Outlook
The report points to four forces shaping value creation through 2031: performance-based contracts scaling to 53% of revenue, industrial reuse and zero-liquid-discharge services expanding the addressable pool, digital water-loss reduction becoming a standalone monetizable service, and modular treatment structures serving remote and fast-growth demand nodes. Investors evaluating entry can compare this market against broader broader water infrastructure industry reports and competition benchmarking studies across the wider GCC utilities landscape.
