Water Consumption in Saudi Arabia

Water Consumption in Saudi Arabia: Managing Scarcity at Scale

Saudi Arabia faces one of the most acute water scarcity challenges of any major economy. The Kingdom receives less than 100 millimetres of average annual rainfall, possesses no permanent rivers or freshwater lakes, and relies on a combination of desalinated seawater, non-renewable groundwater extraction, and treated wastewater to meet the needs of its population, agriculture, and industry. Water management is integral to the Kingdom’s Vision 2030 sustainability objectives. Per-capita water consumption in Saudi Arabia exceeds 250 litres per day, significantly above the global average and among the highest rates in water-scarce nations.

Supply Sources

Desalination: Saudi Arabia is the world’s largest producer of desalinated water, accounting for approximately 22 per cent of global desalination capacity. The Saudi Water Authority (formerly the Saline Water Conversion Corporation) operates a network of desalination plants along both the Red Sea and Arabian Gulf coasts, with total production capacity exceeding 7.5 million cubic metres per day. Desalinated water supplies the majority of municipal and industrial demand in major cities.

Groundwater: Non-renewable fossil aquifers, including the Saq, Tabuk, and Wasia-Biyadh systems, have historically supplied agricultural and rural water needs. Decades of intensive extraction for wheat cultivation and other irrigated agriculture have significantly depleted these aquifer systems. The government’s decision to phase out domestic wheat production and reduce agricultural groundwater consumption reflects recognition of the depletion trajectory.

Treated Wastewater: The reuse of treated wastewater is expanding, with the National Water Strategy targeting a substantial increase in treated effluent reuse for irrigation, industrial processes, and aquifer recharge. The current reuse rate, while growing, remains below potential, representing an area of active investment and policy focus.

Consumption by Sector

Agriculture has historically been the largest water consumer, accounting for over 80 per cent of total water withdrawal in the Kingdom. The phase-out of water-intensive crops and the shift towards controlled environment agriculture, including greenhouse and hydroponic systems, are reducing agricultural water intensity. However, fodder crop production, particularly alfalfa for dairy operations, remains a significant water consumer.

Municipal consumption accounts for approximately 10 per cent of total water use, driven by residential demand in the Kingdom’s growing urban centres. Industrial consumption, including petrochemical processing, mining, and manufacturing, constitutes the remaining share and is projected to grow as industrial diversification accelerates.

Water Tariff Reform

Water tariff reform has been implemented alongside electricity tariff restructuring as part of the Fiscal Balance Program. Tiered pricing for residential water consumption incentivises conservation by imposing progressively higher rates on excessive usage. The National Water Company (NWC) manages urban water distribution and wastewater collection, with performance improvement programmes targeting reduced non-revenue water losses, which have historically exceeded 25 per cent of supply in some distribution networks.

Infrastructure Investment

The Kingdom is investing heavily in water infrastructure. New desalination capacity, including the Jubail 3A and Rabigh 4 independent water producer (IWP) projects, adds to supply. Strategic water storage capacity is expanding through reservoir construction and managed aquifer recharge. Transmission networks connecting coastal desalination plants to inland cities, including Riyadh, represent critical infrastructure enabling urban growth.

Public-private partnerships are a primary delivery mechanism for new water infrastructure. International developers including ACWA Power, Veolia, and Engie participate in desalination and wastewater treatment projects through long-term concession agreements. The water sector’s privatisation and corporatisation programme aims to improve operational efficiency and attract private capital.

Conservation and Efficiency

The Saudi government has set ambitious water conservation targets. Smart metering deployment enables consumption monitoring and leakage detection across distribution networks. Building codes mandate water-efficient fixtures and greywater recycling in new construction. Public awareness campaigns promote water conservation behaviours, supported by the tiered tariff structure.

Agricultural water efficiency improvements, including drip irrigation adoption, crop selection optimisation, and deficit irrigation techniques, are being promoted through the Ministry of Environment, Water and Agriculture. The National Water Strategy targets a significant reduction in per-capita water consumption by 2030.

Outlook

Water security remains a foundational challenge for Saudi Arabia’s economic development. The Kingdom’s response, combining massive desalination investment, demand management, agricultural reform, and wastewater reuse, represents one of the most comprehensive water management programmes globally. For investors and technology providers, the Saudi water sector presents significant opportunities across desalination, distribution, treatment, and efficiency technologies.
