Independent Industrial Water Consulting for Saudi Arabia’s Integrated Refining, Petrochemical & Power Complexes
Vendor-neutral advisory for Jubail, Yanbu, Ras Al-Khair, and Gulf/Red Sea coastal complexes — where seawater cooling, RCER compliance, and the Kingdom’s zero-liquid-discharge trajectory define every water decision. Program audits, seawater cooling and desalination advisory, ZLD and reuse strategy, boiler and RO systems, Legionella compliance, failure analysis, and vendor contract governance.

Saudi industrial complexes run on the sea. Makeup for cooling and process water is overwhelmingly desalinated seawater (SWRO or thermal) or, in coastal complexes, direct once-through and recirculated seawater. That drives a distinctive risk profile: high chloride and sulphate loads, elevated ambient and water temperatures (40–50 °C), aggressive scaling potential, and biofouling in warm seawater loops — all demanding corrosion-resistant metallurgy and disciplined chlorination.
Layered on top is national water policy. The Saudi National Water Strategy targets 100% industrial wastewater reuse in industrial zones by 2030, and new developments such as NEOM mandate zero liquid discharge (ZLD) as the baseline. For an operator, water is no longer a utility line-item — it is a compliance and capital-planning driver. We help translate that trajectory into a practical program roadmap rather than a reactive retrofit.
RCER-2025 and the Seawater Cooling Return Canal
Facilities inside the industrial cities of Jubail, Yanbu, and Ras Al-Khair fall under the Royal Commission Environmental Regulations. RCER-2025 (Volumes I–III) supersedes RCER-2015 with effect from January 2026, tightening discharge and permitting requirements. Key features that shape a water program:
- Regulator: Royal Commission for Jubail & Yanbu (RCJY); MEWA and the environmental authority Kingdom-wide
- Discharge to seawater cooling return canal: governed by RCER coastal water-quality standards (temperature, residual chlorine, metals)
- Pre-treatment before central WWTP: mandatory to defined “major/minor” pollutant limits
- Reuse (MEWA classes A/B/C): treated wastewater quality classes govern permissible reuse applications
- ZLD: baseline for new NEOM facilities; national reuse target 100% in industrial zones by 2030
- Permits: Environmental Permit to Construct and to Operate; 5-year operating permit cycle with monitoring/reporting
Discharge of cooling water to the return canal is explicitly regulated for temperature and residual chlorine — which couples your biofouling-control chlorination strategy directly to a compliance limit. We optimise the two together so microbiological control does not create a discharge exceedance.

Questions Operators Ask Us Here
Does RCER-2025 change how I can discharge cooling water?
RCER-2025 takes effect January 2026 and tightens discharge and permitting. Discharge to the seawater cooling return canal remains regulated for temperature and residual chlorine, so your biofouling chlorination and compliance limits must be optimised together.
How do I prepare for the 2030 industrial reuse and ZLD targets?
We build a staged roadmap — cycle optimisation and reuse first, brine concentration and ZLD where mandated (e.g. NEOM) — so you meet targets without over-capitalising early.
Is your scope only cooling water?
No. It spans seawater cooling, thermal/SWRO desalination, boiler feedwater, RO high-purity trains, reuse/ZLD, degraded-source and brine management, Legionella compliance, and contract/RFP support.
