Saudi Arabia’s Desalinated Water Infrastructure

Part 1: Scale, Growth, and Global Comparisons

Introductory Note

Saudi Arabia, one of the world’s most water-scarce nations, relies heavily on desalination to meet its water demands. With negligible rainfall and no permanent rivers, the country has invested aggressively in converting seawater into potable water. Over decades, it has built one of the largest and most sophisticated desalinated water distribution systems globally, combining advanced technology, massive infrastructure, and significant capital expenditure. This document explores the technical, financial, and operational dimensions of Saudi Arabia’s desalination network, compares it to global projects, and outlines its strategic importance in the nation’s water security.

1. Movement of Desalinated Water Through Underground Pipelines

Saudi Arabia uses a vast network of underground pipelines to transport desalinated water from coastal plants to urban centers and industrial zones. Key features include:

  • Pipeline Material : High-density polyethylene (HDPE) and steel pipes, resistant to corrosion and suitable for long-distance transport.
  • Pumping Stations : Strategically located to maintain pressure over long distances, often powered by renewable or excess grid energy.
  • Control Systems : Advanced SCADA (Supervisory Control and Data Acquisition) systems monitor flow rates, detect leaks, and optimize distribution.
  • Storage Reservoirs : Underground and elevated reservoirs buffer supply, ensuring continuity during peak demand or maintenance.

The Riyadh Water Transmission Line , for example, spans over 400 km, delivering 2.4 million m³/day from Jubail on the Arabian Gulf to the capital.

2. Desalination Capacity and Production

  • Total Desalination Capacity : ~6.5 million cubic meters per day (m³/day), accounting for ~20% of global desalinated water production.
  • Key Plants :
    • Jubail 3B Plant : Largest in the world (1.8 million m³/day).
    • Al Khafji Plant : First fully solar-powered facility (60,000 m³/day).
  • Technologies : Multi-Stage Flash (MSF), Multi-Effect Distillation (MED), and Reverse Osmosis (RO), with RO gaining prominence due to lower energy use.

3. Pipeline Network and Distribution

  • Total Pipeline Length : ~10,000 km of primary and secondary pipelines.

4. Water Usage and % of Total Supply

  • Municipal Use : 50% (domestic consumption, public services).
  • Industrial Use : 30% (oil refining, petrochemicals, mining).
  • Agricultural Use : 20% (down from 60% in the 1990s due to policy shifts).
  • % of Total Water Supply : Desalination accounts for 50% of total water use , with groundwater (40%) and wastewater reuse (10%) making up the rest.

5. Timeline and Historical Development

  • 1970s–1980s : First large-scale plants built (e.g., Jubail, Yanbu).
  • 1990s–2010s : Expansion driven by population growth and Vision 2030.
  • 2020s : Shift toward solar-powered desalination and privatization via the Water Sector Transformation Program.
  • Total Build Time : Continuous development over 50 years , with major upgrades every decade.

6. Total Cost and Capital Expenditure (Capex)

Feasibility of Indus River Diversion - In short, it is impossible

Himalayan River Systems: An Analysis of River Courses and the Feasibility of Indus River Diversion "Diverting the Indus to the Kashmir Valley is highly infeasible. The significant elevation difference and the Pir Panjal range pose major geographical barriers. The project would require immense engineering efforts and astronomical costs. Furthermore, it would likely cause catastrophic flooding and carries severe geopolitical risks" Executive Summary The Himalayan region is the source of major river systems in South Asia, including the Indus and Jhelum. The Karakoram, Ladakh, and Zanskar ranges significantly influence the courses of the Zanskar, Indus, and Shyok rivers, acting as both barriers and channels. The Indus River originates in Tibet and flows northwest through Ladakh and Gilgit-Baltistan, while the Shyok River originates in the Karakoram and joins the Indus. The Zanskar River originates in the Zanskar Range and also flows into the Indus. The Jhelum River originates...

India’s Ethanol Revolution

Image
India’s Ethanol Revolution: Fueling Energy, Farming, and the Future (2018–2030) Over the past seven years, India’s Ethanol Blending Programme (EBP) has transformed from a modest initiative into a cornerstone of energy and agricultural policy. Ethanol production has soared from 1,880 million liters in 2018–19 to 10,000 million liters in 2024–25, achieving 20% petrol blending (E20) ahead of schedule. The feedstock mix has shifted dramatically, with grain-based ethanol, especially maize, now equaling sugarcane’s share, driven by water concerns and policy incentives. This has saved $12.8 billion in crude oil imports (2014–2022) and boosted farmer incomes by ₹87,558 crore. However, rising maize and sugar prices, water stress, and food security concerns pose challenges. By 2030, India aims for 30% blending (E30), requiring 15,000 million liters, with a focus on second-generation (2G) ethanol. Balancing food and fuel demands will need innovative policies, as the program reshapes India’s ene...
