2026-10-10Key Facts: Jubail and Yanbu Power and Water Desalination Utility Company (Marafiq) announced the signing of a 30年 concession agreement with Saudi Aramco Total Refining and Petrochemical Company (Satorp) to develop, operate and maintain an advanced Industrial Wastewater Treatment Plant (IWWTP) for the Amiral complex currently under construction in Jubail II Industrial City. The project value is approximately 5亿 USD (18.75亿 Saudi Riyals), executed by a specially established project company, with shareholding of Marafiq 40%, Veolia Middle East 35%, and Lamar Arabia for Energy 25%. The facility will treat complex industrial wastewater including spent caustic, and the treated water will be reused in the original industrial process, achieving closed-loop reuse.
1. Transaction Structure: A Long-Term Concession with Three-Way Shareholding
Unlike the common EPC general contracting approach, this project adopts a concession model, with a term of up to 30年, carried by a specially established project company. The division of roles among the three shareholders is quite clear:
- Marafiq (40%) — the power and water desalination utility company for Saudi Arabia's two major industrial cities, Jubail and Yanbu, familiar with local utility regulation, industrial customer structure and long-term asset operation, and is the holder of local resources and assets.
- Veolia Middle East (35%) — the Middle East platform of the global water giant, bringing technical capabilities in complex industrial wastewater treatment and reuse processes, especially engineering track records in difficult refinery and petrochemical wastewater.
- Lamar Arabia for Energy (25%) — a local energy investor, supplementing capital and local industrial synergy.
This structure is consistent with the mainstream approach in Middle East industrial water in recent years: owners no longer buy equipment, but buy thirty years of effluent quality and reuse guarantees. For shareholders, the revenue curve shifts from one-off engineering payments to operating cash flow spanning thirty years.
2. Treatment Target: The Toughest Part of Refinery and Petrochemical Wastewater
Amiral is a large-scale integrated refining and petrochemical complex being built by Satorp in Jubail II Industrial City. Its supporting Industrial Wastewater Treatment Plant must treat not ordinary domestic sewage, but complex industrial wastewater streams, with spent caustic specifically named in the official statement.
Spent caustic is a strongly alkaline, high-sulfide, high-COD waste liquid generated from the caustic washing process of refining and petrochemical units. Conventional biological systems can hardly withstand it directly, and wet air oxidation or dedicated pretreatment units are required to destabilize it first. Explicitly including it in the project scope shows that the technical threshold of this IWWTP is far higher than that of a municipal wastewater plant, and also explains why the owner brought in a professional party like Veolia as a shareholder rather than merely as a technical consultant.
The requirements on the output side are equally high: the treated water is not for "discharge after meeting standards," but for reuse in the original industrial process. According to Marafiq, the facility will achieve efficient recovery of wastewater into demineralised water, directly supporting the sustainable operation of the Amiral project. From "treating and disposing" to "sending it back," this is a shift in the industrial water value chain.
3. Technical Logic: From End-of-Pipe Treatment to In-Process Circulation
Placing the positioning of this plant within the water system, its significance goes beyond a single facility.
- Closed-loop reuse — the treated effluent returns to the industrial process, which means both water intake and discharge decrease simultaneously. In a country like Saudi Arabia, which is extremely water-scarce and highly dependent on desalination for industrial water, every cubic meter of reused water simultaneously saves one cubic meter of desalination capacity and the corresponding energy consumption.
- Energy efficiency synergy — Marafiq explicitly mentioned that the project will deliver higher energy efficiency. The energy consumption of industrial wastewater treatment is generally lower than that of desalination for water production. Substituting part of the demineralized water supply with reused water is essentially replacing a high-energy water source with a low-energy water source.
- Reduced environmental footprint — the consortium's stated goal is to "reduce the environmental footprint of industrial operations while maximizing resource efficiency," pointing to a dual reduction in total emissions and resource intensity.
Worth comparing is another route being advanced in the Middle East during the same period: UK-based Bluewater Bio is providing upgrade technology for the MODON Jeddah First Industrial City industrial wastewater treatment plant, increasing treatment capacity from 25 MLD to 40 MLD. Its 6 sets of FilterClear tertiary filtration systems produce 24 MLD of tertiary treated water that is sent to a Reverse Osmosis system for reuse, serving more than 1100 factories. The two paths differ — one is deep reuse supporting a large new refining and petrochemical complex, the other is upgrading and expanding capacity at an existing industrial park facility — but the endpoint is the same: industrial wastewater no longer leaves the industrial park.
IV. Why Now: The Triple Drivers of Saudi Industrial Water
The closing of this deal is the result of three forces acting simultaneously.
- Refining and petrochemical capacity expansion — large new facilities such as Amiral are required at the design and approval stage to include high-level water reuse facilities. Environmental compliance has shifted from "retrofit after completion" to "built in by design."
- Utility company transformation — Marafiq is extending from a traditional power and desalination supplier to an integrated industrial water service provider, converting its existing customer relationships and pipeline network assets in Jubail and Yanbu into entry points for new business.
- International water giants increasing their stakes — Veolia's involvement through equity participation rather than simply supplying equipment reflects Middle Eastern owners' preference for long-term shared performance. For the technology provider, holding equity means staking thirty years of balance sheet on its own process commitments — which in itself is a form of capability endorsement.
For Chinese water companies still primarily engaged in EPC or equipment export, there is a clear signal here: the incremental market for Middle Eastern industrial water is shifting from "can you build it" to "do you dare to be responsible for thirty years of effluent quality."
V. Implications for Chinese Companies
- High-difficulty wastewater is the real moat — streams such as spent caustic, high salinity, and recalcitrant organics that "others cannot treat" are precisely the segments with the highest premiums in concession contracts. General municipal sewage capability is not scarce in the Middle East.
- Reuse rate is becoming a hard indicator — "meeting discharge standards" is no longer sufficient to constitute competitiveness in new industrial projects in the Middle East. Reuse rate and demineralized water substitution rate are the core evaluation criteria. This is consistent with the direction of domestic industrial park wastewater governance moving from "referencing urban standards" to "one standard per park."
- Holding equity is harder than supplying, and also more valuable — supply revenue is recognized on a one-time basis, while equity revenue spans thirty years and is tied to performance. The prerequisite is verifiable long-term operational track record, which is precisely the missing link for most companies going global today.
VI. TIANYI TECH's View
TIANYI TECH believes that this 5亿 USD, 30年 concession transaction marks the complete transition of the Middle Eastern industrial water business model from "project delivery" to "asset operation." For domestic companies, short-term opportunities remain in the supporting supply of high-difficulty wastewater treatment units and membrane-based deep reuse equipment — a segment where Chinese manufacturing already has cost and delivery advantages. In the medium term, two shortcomings must be addressed: long-term operational track record and localized consortiums. Otherwise, companies will remain stuck at the low-margin end of the value chain. Reuse rate is becoming the only universal language in this competition.
