Saudi Arabia, a nation characterized by arid climate and minimal freshwater resources, has long relied on water desalination to meet its growing domestic and industrial water needs. With the Kingdom’s ambitious Vision 2030 strategy driving industrial growth—especially in its coastal economic and industrial zones—the need for a reliable, sustainable water supply is more critical than ever.

In this context, conducting a water desalination plant feasibility study becomes essential. Engaging with experienced feasibility study companies in Saudi Arabia ensures that such large-scale infrastructure projects are viable, efficient, and aligned with environmental, technical, and economic realities.

The Strategic Importance of Coastal Industrial Zones

Saudi Arabia’s coastal regions—such as Jubail, Yanbu, Jazan, and NEOM—are being developed into high-value industrial hubs focusing on petrochemicals, manufacturing, logistics, renewable energy, and maritime trade. These zones are designed to attract international investment, create jobs, and diversify the Kingdom’s economy beyond oil.

However, their success hinges on uninterrupted access to industrial-grade water, which is essential for:

• Cooling systems in power and petrochemical plants

• Boiler feed water for manufacturing processes

• Cleaning and maintenance operations

• Supporting population growth in surrounding urban areas

Given the limited availability of natural freshwater sources, desalination becomes the primary solution.

Why Conduct a Feasibility Study?

A feasibility study helps evaluate whether a proposed water desalination plant project is achievable from a technical, financial, regulatory, and environmental standpoint. It provides decision-makers with detailed information about:

• Site suitability

• Water demand forecasts

• Technology options (e.g., RO, MSF, MED)

• Capital and operating costs

• Return on investment (ROI)

• Environmental impact

• Regulatory compliance

Without this foundational assessment, project stakeholders risk delays, cost overruns, environmental penalties, or failure to meet water supply demands.

Role of Feasibility Study Companies in Saudi Arabia

Feasibility study companies in Saudi Arabia play a central role in guiding water infrastructure development. These firms combine local regulatory knowledge with technical expertise, ensuring project alignment with national development goals and global best practices.

Their role includes:

1. Technical Feasibility

• Analysis of coastal site conditions (e.g., seawater salinity, temperature, tides).

• Identification of the most suitable desalination technology.

• Evaluation of grid connection, power sources, and pipeline routing.

• Infrastructure compatibility with existing water networks.

2. Economic and Financial Assessment

• Capital expenditure (CAPEX) and operational expenditure (OPEX) modeling.

• Cost comparison of design-build vs PPP vs BOOT models.

• ROI calculations based on projected water tariffs and consumption.

• Sensitivity analysis under various scenarios (e.g., energy cost fluctuation).

3. Environmental and Regulatory Review

• Environmental Impact Assessment (EIA) in compliance with Saudi environmental laws.

• Marine ecosystem protection and brine disposal strategies.

• Coordination with Saudi Ministry of Environment, Water & Agriculture (MEWA) and Saline Water Conversion Corporation (SWCC).

4. Demand and Supply Forecasting

• Population and industrial growth modeling in coastal zones.

• Future expansion capacity planning.

• Integration with national water grid or industrial water loops.

Types of Desalination Technologies Considered

During the feasibility study, consultants assess various desalination technologies such as:

• Reverse Osmosis (RO)

• Most energy-efficient option

• Modular and scalable

• Preferred for new sustainable developments
   

• Multi-Stage Flash (MSF)

• Suitable for large-scale facilities

• Integrated with thermal power plants

• Higher energy demand but robust
   

• Multi-Effect Distillation (MED)

• Efficient in low-temperature waste heat recovery

• Lower chemical usage

• Suitable for co-generation projects

The choice depends on site-specific factors, energy availability, and environmental impact.

Leading Feasibility Study Companies in Saudi Arabia

Saudi Arabia is home to several reputed feasibility study firms and engineering consultancies that specialize in infrastructure and water projects. Some of the prominent ones include:

1. Saudi Consulting Services (SAUDCONSULT)

One of the oldest engineering and consultancy firms in the Kingdom, offering services in water, energy, and environmental sectors.

2. Dar Al Riyadh

Known for urban and infrastructure feasibility studies, including water treatment and desalination.

3. AECOM Saudi Arabia

Global engineering firm with local offices delivering desalination plant design and financial feasibility support.

4. ILF Consulting Engineers

Specialized in water infrastructure, ILF has executed feasibility studies for desalination and wastewater treatment plants in the region.

5. WorleyParsons Arabia

A major player in feasibility, engineering, and project management for industrial water systems.

These firms collaborate with government authorities like SWCC, NWC (National Water Company), and the Royal Commission for Jubail and Yanbu to develop holistic and compliant desalination strategies.

Environmental Considerations

Desalination, while necessary, poses environmental challenges:

• Brine discharge can damage marine ecosystems if not properly managed.

• High energy consumption contributes to carbon emissions unless renewable sources are used.

• Intake systems can harm marine life.

Feasibility study companies address these by:

• Recommending zero-liquid discharge (ZLD) or brine concentration techniques

• Exploring solar-powered desalination or integration with waste heat from nearby industries

• Suggesting marine outfall designs that dilute and disperse brine safely

Opportunities for Public-Private Partnerships (PPPs)

Feasibility studies often reveal that PPP models are highly suitable for desalination projects in industrial zones. Through PPPs, the government shares risk and capital burden with private operators, who bring innovation and operational efficiency.

Saudi Arabia has already launched several successful PPP desalination projects through entities like:

• Water and Electricity Holding Company (Badeel)

• Saudi Water Partnership Company (SWPC)

Feasibility consultants guide government and private partners in structuring these agreements transparently and profitably.

Conclusion

Water security is not just a domestic issue for Saudi Arabia—it is a foundational pillar of the Kingdom’s industrial, economic, and environmental sustainability goals. With coastal industrial zones forming the backbone of Vision 2030's industrial diversification, ensuring adequate, cost-effective water supply is a national priority.

Feasibility study companies in Saudi Arabia serve as essential partners in this mission. By delivering in-depth, multi-dimensional assessments, they help government bodies and investors make informed decisions on desalination plant development—balancing technology, economy, environment, and long-term strategic needs.

As industrial expansion continues, the value of these companies will only grow—supporting Saudi Arabia’s transformation into a water-resilient, industrial powerhouse of the region.
